Description

Technical Field

[0001] The present disclosure relates to a fragrance premix composition comprising a silicone polymer, an amino-functional material and a fragrance material comprising an aldehyde and / or ketone moiety, wherein these components are suitably miscible. The present disclosure also relates to a consumer product composition comprising such a premix. The present disclosure also relates to related methods of preparing and using such premixes and products. Background Art

[0002] Manufacturers of consumer products such as fabric care compositions desire an efficient way to deliver perfume materials to their products and, perhaps more importantly, to the consumer's target surface when treated with the consumer product. For example, if the consumer product is used to treat fabrics during a laundry washing operation, it is highly preferred that the perfume material be deposited onto the fabrics rather than washed down the drain.

[0003] Perfume raw materials ("PRMs") can be blended with silicones and can improve deposition efficiency; however, there is room for further improvement. Aminosilicones can be used in such blends with certain PRMs and deposition efficiency can be further improved due to the interaction between the amine groups of the aminosilicone and the PRM.

[0004] However, the loading capacity and / or number of interactions may be limited by the number of amino groups on the silicone. Furthermore, it is not necessarily a simple matter to increase the amine content of the aminosilicone, as this will tend to increase the solubility of the aminosilicone, thus reducing its tendency to readily emulsify in water and / or deposit onto fabrics. Additionally, if the aminosilicone is too hydrophilic, it is believed that certain PRMs (many of which are relatively hydrophobic) will not partition into the silicone droplets and therefore will not associate adequately with the silicone polymer, resulting in suboptimal perfume deposition upon use.

[0005] Other amine-containing (non-silicone) compounds are known to be useful for perfume delivery purposes, but such compounds tend to cause undesirable discoloration of the perfume premix and / or the final product.

[0006] There is a need for improved fragrance premix compositions, related consumer product compositions, and / or related methods that address one or more of the above-mentioned problems. Summary of the invention

[0007] The present disclosure relates to fragrance premix compositions and related consumer products.

[0008] For example, the present disclosure is directed to a fragrance premix composition comprising: a siloxane polymer, wherein the siloxane polymer is characterized by at least one of: (a) a percent extractable after 24 hours (% extractable) of less than 8, and / or (b) a solubility in water measured at 21° C. of less than about 1000 mg / L, and / or (c) an amine content of 0.0 to about 2.2; an amino-functional material, wherein the amino-functional material is characterized by a molecular weight of less than about 1000 Daltons, and wherein the amino-functional material comprises at least one amine moiety selected from a primary amine moiety, a secondary amine moiety, or a combination thereof; and a fragrance material, the fragrance material comprising one or more fragrance raw materials, wherein the one or more fragrance raw materials comprise an aldehyde moiety, a ketone moiety, or a combination thereof; wherein the mixture of the siloxane polymer, the amino-functional material, and the one or more fragrance materials is suitably miscible, for example, characterized by a percent transmittance (%T) at 480 nm of at least 40 when in a 9.9:0.1:0.1 weight ratio. The present disclosure also relates to methods of making such fragrance premix compositions.

[0009] The present disclosure also relates to consumer product compositions comprising such fragrance premix compositions, consumer product compositions containing droplets comprising components of the premix compositions, and methods of making and using such consumer product compositions. DETAILED DESCRIPTION

[0010] The present disclosure relates to fragrance premix compositions and related consumer products and methods. The fragrance premix compositions comprise silicone polymers, amino-functional materials, and fragrance materials comprising certain fragrance raw materials. Each of these materials is selected based on certain properties and compatibility, as described in more detail below. For example, the silicone polymer may be characterized by a certain solubility in water, the amino-functional material may be characterized by a relatively low molecular weight, and the PRM may contain certain functional groups. In addition, these three components may be relatively miscible with each other. Failure to appropriately select one or more components may result in a premix or consumer product that is less efficient (e.g., as demonstrated by reduced fragrance performance).

[0011] Without being bound by theory, it is believed that by at least partially removing the amine groups from the siloxane polymer, the loading efficiency of the PRM into the droplets can be increased while maintaining the relative hydrophobicity of the siloxane, thereby allowing for convenient preparation of the emulsion and / or enabling deposition to occur more efficiently.

[0012] Additionally, it has been found that pairing the amino-functional material with the silicone polymer can result in improved color stability in the premix and / or final product. Without wishing to be bound by theory, it is believed that at least some of the amino-functional material can partition into the silicone droplets and the amine groups can thereby be "protected" from color-changing side reactions.

[0013] The components, premixes, compositions and methods are described in more detail below.

[0014] As used herein, the articles "a" and "an" when used in a claim are understood to refer to one or more of the things protected or described by the claim. As used herein, the terms "comprising," "including," and "containing" are intended to be non-limiting. The compositions of the present disclosure may comprise, consist essentially of, or consist of the components of the present disclosure.

[0015] The term "substantially free of" or "substantially free from" may be used herein. This means that the referenced material is very little, not intentionally added to the composition to form part of the composition, or preferably the referenced material is not present at analytically detectable levels. This refers to compositions in which the referenced material is present only as an impurity in one of the other materials that are intentionally added. If present, the referenced material may be present at a level of less than 1%, or less than 0.1%, or less than 0.01%, or even 0% by weight of the composition.

Such compositions can be used as laundry pre-treaters, laundry post-treaters, or can be added during the rinse cycle or wash cycle of a laundry operation.

[0017] As used herein, "fragrance premix composition," "premix composition," and "premix" are used interchangeably unless otherwise specified.

[0018] As used herein, unless otherwise specified, "amine content," "amine value," and "amine content value" are used interchangeably and can be determined according to the method provided in the Test Methods section.

[0023] Fragrance premix composition

[0024] The present disclosure relates to fragrance premix compositions. The fragrance premix compositions of the present disclosure can be useful components of consumer product compositions and can help improve the fragrance delivery and performance of those consumer product compositions compared to products that do not use such premixes. In addition, it is believed that combining ingredients in a premix in a consumer product provides more effective fragrance delivery and performance, particularly in aqueous consumer products, than if the ingredients were added to the consumer product individually (e.g., not as a premix).

[0025] The perfume premix composition comprises a silicone polymer, an amino-functional material and a perfume material, each of which is described in more detail below. The components should be selected based on various properties. Failure to make an appropriate selection may result in a suboptimal premix composition.

[0026] The silicone polymer, amino-functional material and fragrance material should be suitably miscible with one another as a ternary system (silicone polymer, amino-functional material, fragrance material). If these components are not suitably miscible, they may not associate with one another and / or may not form droplets containing all three components in an emulsion or consumer product composition. It is desirable to form such droplets to facilitate what is believed to be the most effective fragrance delivery system.

[0027] To determine whether the three selected components are appropriately miscible, they can be mixed together and visually inspected; if a mixture of 9.9 parts (by weight) of a siloxane polymer, 0.1 parts of an amino-functional material, and 0.1 parts of a perfume material is mixed with a vortex mixer, water (if any) is removed, and the mixture is then visually inspected, if the mixture appears transparent, the components can be considered miscible. Additionally or alternatively, to determine whether the three selected components are appropriately miscible, they can be mixed together and analyzed for percent transmittance. More specifically, a mixture of 9.9 parts (by weight) of a siloxane polymer, 0.1 parts of an amino-functional material, and 0.1 parts of a perfume material can be provided, mixed with a vortex mixer, and then analyzed for percent transmittance (%T) at 480 nm. More details of these measurements are provided in the Test Methods section below. The %T of the ternary system at 480 nm may be at least 40, or at least 50, or at least 60, or at least 75, or at least 80, or at least 85, or at least 90, or at least 95, or at least 98. Larger %T values ​​are associated with greater clarity of the mixture, indicating a greater degree of miscibility.

[0028] The siloxane polymer and the amino-functional material can be suitably miscible in the absence of a fragrance material. A mixture of 9.9 parts (by weight) of a siloxane polymer and 0.1 parts of an amino-functional material (i.e., a binary system) can be provided, mixed with a vortex mixer, and then analyzed for percent transmittance (%T) at 480 nm according to the test method provided below. The %T at 480 nm of the binary system can be at least 40, or at least 50, or at least 60, or at least 75, or at least 80, or at least 85, or at least 90, or at least 95, or at least 98. Larger %T values ​​are associated with greater clarity of the mixture, indicating a greater degree of miscibility.

[0029] The fragrance premix composition is a liquid. The premix may be characterized by a viscosity of, for example, about 10 Pa·s to about 10000 Pa·s, preferably about 10 Pa·s to about 5000 Pa·s, preferably about 10 Pa·s to about 1000 Pa·s, preferably about 10 Pa·s to about 500 Pa·s, preferably about 20 Pa·s to about 400 Pa·s, more preferably about 25 Pa·s to about 300 Pa·s, even more preferably about 100 Pa·s to about 300 Pa·s, measured at 0.1 rad / s and 25°C. For processability reasons, it may be desirable to obtain a fragrance premix composition having a target viscosity, particularly because a premix having a very high viscosity may be difficult to formulate into a product.

[0030] The perfume premix composition may be substantially free of water. The premix composition may contain less than 10%, or less than 5%, or less than 2%, or less than 1%, or less than 0.5%, or less than 0.1%, or even 0% water by weight of the premix composition. For example, such a low water premix may be desirable when the premix is ​​to be formulated into a low water consumer product, such as a solid composition or a composition encapsulated by a water soluble film. In this case, the silicone polymer may be a fluid that is the bulk of the premix.

[0031] The fragrance premix composition may include water. The fragrance premix composition may include from about 1% to about 90%, or from about 1% to about 75%, or from about 1% to about 60%, or from about 1% to about 50%, or from about 5% to about 50%, or from about 10% to about 50%, or from about 25% to about 50% water by weight of the composition. Given that silicone polymers are relatively hydrophobic, the presence of water may promote the formation of droplets, which may promote more convenient dispersion of the premix in a consumer product.

[0032] The fragrance premix composition may be in the form of an emulsion. The emulsion may preferably be an oil-in-water emulsion. The emulsion may comprise a plurality of droplets, preferably wherein the plurality of droplets are characterized by an average diameter of from about 1 micron to about 10 microns, preferably from about 1 micron to about 5 microns. Without wishing to be bound by theory, it is believed that a certain minimum size of droplets is desired for effective deposition onto a target surface, but droplets exceeding a certain size may produce performance and / or stability issues, such as spotting on the target surface.

[0033] The fragrance premix composition may include one or more emulsifiers. As used herein, "emulsifier" and "emulsifying agent" are used interchangeably. Selecting an appropriate emulsifier can facilitate the formation of droplets of a desired size, and / or the premix is ​​stably incorporated into the final product. The emulsifier may also be selected so as to have no undesirable effect on the viscosity of the emulsion, for example by increasing the viscosity to an undesirable level.

[0034] The one or more emulsifiers may include a nonionic surfactant. Suitable nonionic surfactants may include alkoxylated fatty alcohols. The nonionic surfactant may be selected from ethoxylated alcohols and ethoxylated alkylphenols of formula R(OC2H4), OH, wherein R is selected from the group consisting of an aliphatic hydrocarbon radical containing about 8 to about 15 carbon atoms and an alkylphenyl radical containing about 8 to about 12 carbon atoms in the alkyl radical, and the average value of n is about 5 to about 15.

[0035] The one or more emulsifiers may include linear emulsifiers, branched emulsifiers or mixtures thereof, preferably linear nonionic surfactants, branched nonionic surfactants or mixtures thereof. In particular, linear emulsifiers may be used to emulsify fragrance materials, and branched emulsifiers may be used to emulsify silicone polymers, in particular amino-functional silicone polymers.

[0036] The one or more emulsifiers may be substantially hydrophobic. The one or more emulsifiers may be characterized by an HLB value of about 5 to about 20, or about 8 to about 16. The HLB value of the nonionic surfactant may be determined according to the method provided below.

[0037] The silicone polymers, amino-functional materials and fragrance materials are described in more detail below.

[0038] Siloxane polymer

[0039] The perfume premix composition of the present disclosure comprises silicone polymers (or simply "silicone", as used herein). Without wishing to be bound by theory, it is believed that the hydrophobic nature of silicone polymers promotes efficient deposition of perfume materials onto target surfaces such as fabrics during laundry operations.

[0040] The perfume premix composition may comprise from about 30% to about 98%, or from about 40% to about 95%, or from about 50% to about 90%, or from about 60% to about 85% silicone polymer by weight of the perfume premix composition.

[0041] The siloxane polymer can be relatively hydrophobic. Relatively hydrophobic siloxanes can be emulsified in water, in a premix, and / or in a consumer product composition and form droplets in the composition. This can enable the amino-functionalized material and the fragrance material to be distributed into the droplets, allowing the components of the ternary system to associate with each other, thereby resulting in effective fragrance deposition and performance in end use, and improved color stability. On the other hand, if the siloxane is too hydrophilic or too soluble in water, it may not promote effective distribution or fragrance delivery.

[0042] The siloxane polymer may have a relatively low solubility in water. The siloxane polymer may be characterized by a solubility in water measured at 25° C. of less than about 1000 mg / L (e.g., less than about 1000 mg of siloxane dissolved in 1 L of water), or less than about 750 mg / L, or less than about 500 mg / L, or less than about 250 mg / L, or less than about 150 mg / L, or less than about 100 mg / L.

[0043] Siloxane polymers can be characterized by their percent extraction ("% extraction"). The percent extraction of a siloxane polymer is related to how much (usually reported as % by weight) of the initial polymer sample combined with DI water can be found in water after a certain period of time. Therefore, a relatively low % extraction value indicates a relatively low degree of water solubility. As described above, it may be preferred that the siloxane polymers of the present disclosure are characterized by relatively low water solubility, and therefore it is also preferred to follow relatively low % extraction values. For example, the siloxane polymers of the present disclosure may be characterized by an % extraction value of less than 8%, or less than 5%, or less than 4%, or less than 2%, or less than 1%, or less than 0.5%, or even less than 0.1% after 24 hours. The siloxane polymers of the present disclosure may be characterized by an % extraction value of less than 15%, or less than 10%, or less than 5%, or less than 3%, or less than 2%, or less than 1.5% after six days. The percent extraction is determined according to the method provided in the test method section below.

[0044] The molecular weight of the siloxane is usually indicated by the viscosity of the reference material. The siloxane may have a viscosity of about 10 to about 2,000,000 centistokes at 25°C. Suitable siloxanes may have a viscosity of about 50 to about 200,000 centistokes, or about 100 to about 100,000 centistokes, or about 500 to about 60,000 centistokes, or about 1000 to about 50,000 centistokes, or about 1000 to about 10,000 centistokes at 25°C. Relatively high molecular weights and / or viscosities of siloxanes may be preferred because such siloxanes may be relatively hydrophobic.

[0045] Preferably, the silicone polymer is fluid at room temperature (eg, 22° C.) so that efficient dispensing and droplet formation can occur conveniently.

[0046] Suitable siloxanes may be linear, branched or cross-linked. Siloxanes may include siloxane resins. Siloxane resins are highly cross-linked polymeric siloxane systems. Cross-linking may be introduced by combining trifunctional and tetrafunctional silanes with monofunctional or difunctional silanes or both during manufacture of the siloxane resin.

[0047] Suitable siloxanes may include non-functionalized siloxane polymers, functionalized siloxane polymers, or combinations thereof. Siloxanes may include non-functionalized siloxane polymers. (Non-functionalized means that the functional groups, if present, are generally non-reactive - e.g., methyl groups.) Siloxane polymers may include polyalkyl and / or phenyl siloxane fluids, resins, and / or gums.

[0048] The silicone polymer may include aminosilicone, silicone polyether, polydimethylsiloxane (PDMS), cationic silicone, silicone polyurethane, silicone polyurea or a mixture thereof. The silicone polymer may preferably be selected from polydimethylsiloxane (PDMS) polymer, aminosilicone or a mixture thereof.

[0049] The siloxane polymer may include a cyclic siloxane. The cyclic siloxane may include a cyclic siloxane of the formula [(CH3)2SiO] n A cyclic polymethylsiloxane wherein n is an integer which may range from about 3 to about 7, preferably from about 5 to about 6.

[0050] The siloxane polymer may include at least one methyl group on at least some of the siloxane atoms, or at least two methyl groups on at least some of the siloxane atoms. Such polymers may also contain additional functional moieties, such as amino functional moieties, or such polymers may be free of additional functional moieties. The siloxane polymer may be polydimethylsiloxane (PDMS).

[0051] The siloxane polymer may have an empirical structure according to the following formula (I):

[0052] [R1R2R3SiO 1 / 2 ] n [R4R4SiO 2 / 2 ] m [R4SiO 3 / 2 ] j Formula (I)

[0053] in:

[0054] i) Each of R1, R2, R3 and R4 can be independently selected from the group consisting of: H, -OH, C1-C 20 Alkyl part, C1-C 20 Substituted alkyl moiety, C6-C 20 Aryl moiety, C6-C 20 Substituted aryl moieties, alkylaryl moieties and / or C1-C 20 an alkoxy moiety;

[0055] ii) n may be an integer from about 2 to about 10, or from about 2 to about 6; or is 2; and n=j+2 is selected;

[0056] iii) m may be an integer from about 5 to about 8,000, from about 7 to about 8,000, or from about 15 to about 4,000; and

[0057] iv) j may be an integer from 0 to about 10, or from 0 to about 4, or is 0.

[0058] In the siloxane polymer according to formula (I), the R2, R3 and R4 groups may independently comprise methyl, ethyl, propyl, C4-C 20 Alkyl and / or C6-C 20 Aryl moiety. Each of R2, R3 and R4 may be a methyl group. Each R1 moiety that blocks the end of the siloxane chain may include a moiety selected from the group consisting of hydrogen, methyl, methoxy, ethoxy, hydroxy, propoxy and / or alkoxy.

[0059] Non-limiting examples of such siloxanes are polydimethylsiloxanes (interchangeably used herein with "polydimethylsiloxane" or "PDMS" or "dimethicone"), such as Xameter PMX 200 fluid available from Dow Chemicals (Midland MI), and / or silanol-terminated siloxanes (also known as dimethiconols), such as DMS-S31, DMS-S32, and DMS-S42, all available from Gelest Inc. (Morrisville, PA).

[0060] The siloxane polymer may be a homopolymer or a homopolymer or copolymer comprising one or more of the following repeating units: diphenylsiloxane, phenylmethylsiloxane, alkylarylsiloxane, 2-phenylpropylmethylsiloxane, ethylmethylsiloxane, propylmethylsiloxane, butylmethylsiloxane, octylmethylsiloxane, dodecylmethylsiloxane, tetradecylmethylsiloxane, hexadecylmethylsiloxane, octadecylmethylsiloxane or mixtures thereof.

[0061] Examples of such polymers are: PDM-1922, PDM-0821, PMM-1043, PMM-1025, PMM-0021, APT-133, APT-213, APT-263, ALT-143, Alt-281, DMA-021 (all available from Gelest Inc, Morrisville, PA) and / or Silwax 3H12-MS, Silwax 3H-MS and Silwax-L118 (all available from Siltech Corporation, Toronto, Canada).

[0062] Siloxanes can include functionalized siloxane polymers. Functionalized siloxane polymers can include one or more functionalized moieties selected from the group consisting of amino, amido, alkoxy, hydroxyl, methanol, polyether, carboxyl, hydride, sulfhydryl, sulfate, phosphate and / or quaternary ammonium moieties. These moieties can be directly connected to the siloxane backbone through divalent alkylene groups (i.e., "side groups"), or can be part of the backbone. Suitable functionalized siloxane polymers include materials selected from the group consisting of aminosiloxanes, amidosiloxanes, siloxane polyethers, siloxane-urethane polymers, quaternary ABn siloxanes, aminoABn siloxanes, and combinations thereof.

[0063] The silicone polymer may include aminosilicones (also disclosed herein as "amino-functional silicones" and used interchangeably therewith). Aminosilicones may be preferred because such silicone polymers provide additional amine groups for further perfume loading, thereby providing a more effective perfume delivery system. Suitable silicone polymers may preferably contain amine groups but not other hydrophilic functional groups, such as carboxyl or hydroxyl groups, because such functional groups may undesirably increase the water solubility of the silicone polymer without providing suitable perfume loading sites for aldehyde- or ketone-containing PRMs.

[0064] Suitable aminosilicones may have an empirical structure according to formula (II):

[0065] [R1R2R3SiO 1 / 2 ] (j+2) [(R4Si(XZ)O 2 / 2 ] k [R4R4SiO 2 / 2 ] m [R4SiO 3 / 2 ] j Formula (II),

[0066] in:

[0067] R1, R2, R3 and R4 are each independently selected from -H, -OH, C1-C 20 Alkyl, C1-C 20 Substituted alkyl, C6-C 20 Aryl, C6-C 20 Substituted aryl, alkylaryl, C1-C 20 Alkoxy and combinations thereof, provided that in addition to the other groups mentioned, R1 may also be selected from XZ;

[0068] X is a divalent alkylene group containing 2 to 12 carbon atoms and / or is independently selected from -(CH2) s -、-CH2-CH(OH)-CH2-、 and mixtures thereof, wherein s is from about 2 to about 10 on average;

[0069] Z independently chooses freedom and The group consisting of, wherein R5 is selected from -H, C1-C 20 Alkyl, C1-C 20 Substituted alkyl and combinations thereof such that at least one R5 on each nitrogen is a hydrogen atom;

[0070] k is about 3 to about 40 on average;

[0071] m averages from about 100 to about 2,000; and

[0072] j is about 0 to about 10 on average.

[0073] In preferred siloxane polymers according to formula (II), R1, R2, R3 and R4 are all -CH3 groups and j=0.

[0074] It may be preferred that the silicone polymer comprises a siloxane according to the following structure:

[0075] or mixtures thereof, wherein k and m are as defined above with respect to formula (II). Such silicone polymers are believed to be particularly useful in the perfume premixes of the present disclosure.

[0076] The aminofunctional silicone can be characterized by one or more amine content values. The amine content, i.e., the primary, secondary, tertiary and / or total amine value (meq / g), is defined as the milliequivalents of amine functional groups (primary, secondary, tertiary and / or total amines) present in one gram of sample. Without wishing to be bound by theory, it is believed that the amine content of the aminofunctional silicone contributes, at least in part, to the solubility of the aminofunctional silicone in water. For example, as the amine content increases, the aminofunctional silicone is generally more soluble in water. Therefore, it may be desirable to limit the nitrogen content of the aminofunctional silicone to maintain a relatively low solubility, thereby promoting the partitioning of the fragrance material from the aqueous phase of the emulsion.

[0077] The aminofunctional siloxanes may be characterized by a total amine content of from about 0.05 to about 2.2, preferably from about 0.1 to about 2.14, or from about 0.071 to about 1.78, or from about 0.71 to about 1.43, or from about 0.14 to about 1.07, or from about 0.14 to about 0.71, or from about 0.21 to about 0.71, or from about 0.36 to about 0.71. The aminofunctional siloxanes may be characterized by a primary amine content of from about 0.05 to about 2.2, preferably from about 0.071 to about 2.14, or from about 0.071 to about 1.78, or from about 0.71 to about 1.43, or from about 0.14 to about 1.07, or from about 0.14 to about 0.71, or from about 0.21 to about 0.71, or from about 0.36 to about 0.71. The amino-functional silicone may be characterized by a ratio of primary amine content to total amine content of from about 1:2 (e.g., 50%) to about 2:2 (e.g., 100%), or about 1.2:2, or about 1.5:2, or about 1.8:2. It may be preferred to select an amino-functional silicone having a relatively high proportion of primary amines compared to total amines to improve PRM loading efficiency since it is believed that the PRM residues are associated with or may even have reacted with primary amines on the fabric.

[0078] The amino-functional siloxane may be characterized by the weight percent of nitrogen. For example, the amino-functional siloxane may be characterized by a nitrogen content of from about 0.1% to about 4%, or from about 0.1% to about 3%, or from about 0.1% to about 2%, or from about 0.2% to about 1.5%, or from about 0.2% to about 1.0%, or from about 0.3% to about 0.8%, or from about 0.3% to about 0.75%, reported as the functional group equivalent weight percent. The functional group equivalent weight percent may be determined by the amine value of the amino-functional siloxane, as described in more detail in the test methods section. The siloxane polymer may be free of nitrogen, in which case its nitrogen content may be 0.0%; therefore, a suitable siloxane may be characterized by a nitrogen content of from 0.0% to about 4%.

[0079] Exemplary commercially available aminosilicones include Xiameter 8566, Xiameter 8822, available from Dow Performance Silicones; KF-873, KF-861, KF-867, KF-8003, available from Shin-Etsu Silicones of North America, Akron, Ohio; and Magnasoft Plus and SF-1708, available from Momentive Performance Materials, Tarrytown, NY.

[0080] Amino Functionalized Materials

[0081] The fragrance premix composition of the present disclosure comprises an amino-functional material. It is believed that the amino-functional material associates with the fragrance raw materials described herein and promotes the deposition and release of the fragrance when used, for example, in a consumer product. In addition, it is believed that when the amino-functional material can be fully associated with the siloxane polymer, further deposition and color stability benefits can be achieved.

[0082] The fragrance premix composition may comprise from about 1% to about 20%, or from about 2% to about 15%, or from about 3% to about 12%, or from about 4% to about 10%, or from about 5% to about 10%, of the amino-functional material, by weight of the fragrance premix composition.

[0083] The amino-functionalized material may be characterized by a relatively low molecular weight. A relatively low molecular weight may be preferred for mass efficiency reasons (e.g., a favorable / high ratio of amine groups to molecular weight). For example, the amino-functionalized material may be characterized by a molecular weight of about 40 Daltons to about 1000 Daltons, preferably about 50 Daltons to 800 Daltons, more preferably about 60 Daltons to about 600 Daltons, even more preferably about 60 Daltons to about 500 Daltons.

[0084] The amino-functionalized material may contain one, two or three amine moieties per molecule, preferably one or two amine moieties. The amine moieties may be selected from the group consisting of a primary amine moiety, a secondary amine moiety or a combination thereof. It is believed that primary and / or secondary amine moieties may associate better with PRMs than tertiary and / or quaternary amine moieties. In addition, two or even three amine moieties may provide improved association / loading in combination with fragrance raw materials compared to compounds having only one amine group. However, as described in more detail below, it may be desirable to limit the number of amine groups.

[0085] Generally, the greater the number of amine moieties, the greater the solubility of the compound in water. It is believed that if a material is too soluble in water / too hydrophilic, it may not be sufficiently miscible with siloxanes, which are typically hydrophobic. One way to quantify the amine content of a molecule is the amine equivalent weight of the molecule. For the purposes of this disclosure, the amine equivalent weight is defined as the molecular weight of the amino-functionalized material divided by the sum of the number of primary amine groups and the number of secondary amine groups per molecule. This is expressed below as the equation:

[0086]

[0087] The amino-functional material may have an amine equivalent weight of about 25 g / mol to 300 g / mol, preferably about 50 g / mol to about 180 g / mol, more preferably about 60 g / mol to about 130 g / mol.

[0088] The amino-functionalized material may be substantially free of any hydrophilic moiety other than primary and / or secondary amines, because such hydrophilic moieties tend to increase the water solubility of the material. Such hydrophilic moieties may include tertiary amine groups, hydroxyl groups (preferably hydroxyl groups not separated by two carbon atoms from primary or secondary amine groups), polyether groups, and carboxyl groups or their salts. Preferably, the material contains no (zero) hydrophilic moieties other than primary or secondary amines. If the material does contain hydrophilic moieties other than primary or secondary amines, the hydrophilic group equivalent weight of the amino-functionalized material is preferably greater than 100. As used in the present disclosure, the hydrophilic group equivalent weight is defined as the molecular weight of the amino-functionalized material divided by the number of hydrophilic groups (excluding primary and secondary amines) in the amino-functionalized material molecule. This is expressed as the equation below:

[0089]

[0090] It is believed that certain amino-functional materials may work better than other materials in the compositions of the present disclosure due to their amine moiety type and / or structure. For example, the amino-functional material may be characterized by one of the following: (a) comprising a total of one primary amine moiety and no secondary amine moieties; or (b) comprising a total of two primary amine moieties and no secondary amine moieties; or (c) one primary amine moiety and one secondary amine moiety, preferably wherein the primary amine moiety and the secondary amine moiety are separated by two carbon atoms; or (d) one primary amine moiety or a secondary amine moiety separated from a hydroxyl group by two carbon atoms.

[0091] The amino-functional material may be selected from the group consisting of: (a) an aliphatic amino-functional material, which may be linear or branched, preferably branched; (b) an alicyclic amino-functional material; (c) an amino-functional silane; (d) an amino alcohol in which one primary or secondary amine moiety is separated from the hydroxyl group by two carbon atoms; or (e) a mixture thereof. The amino-functional material may be substantially free of aromatic amines (e.g., when the amino-functional moiety is directly attached to an aromatic ring), or even substantially completely free of aromatic moieties, as such moieties tend to increase the solubility of the amino-functional material and may therefore make it less likely to associate with the hydrophobic siloxane.

[0092] The amino-functional material may include an aliphatic amino-functional material that is a linear chain. Suitable linear aliphatic amino-functional materials may include octylamine, nonylamine, decylamine, or mixtures thereof. For such materials, monoamines are considered to be preferred because diamines tend to be solid at room temperature and are more difficult to process.

[0093] Suitable aliphatic amino functional materials may preferably be branched. Such materials may include: 2-ethylhexylamine; branched tridecylamine; tert-butylamine; neopentyldiamine (2,2-dimethylpropane-1,3-diamine); trimethyl-1,6-hexanediamine; 2-aminoheptane; 2-butyloctylamine; or mixtures thereof.

[0094] Suitable cycloaliphatic amines preferably have a structure according to formula (III):

[0095]

[0096] wherein the substituents R1, R2, R3, R4, R5 and R6 are independently selected from -NH2, -H, a hydrophilic group, an alkyl group, an alkenyl group, a substituted alkyl group, an alicyclic group having 1 to 10 carbon atoms, or a substituted alicyclic group having 1 to 10 carbon atoms; n is 0 to 3, preferably n is 1; provided that the compound according to formula (III) has 1 to 3 primary and / or secondary amine groups, preferably 1 to 3 primary amine groups, more preferably 2 primary amine groups. It may be preferred that the alicyclic amino-functionalized material also meets the above criteria for amine equivalent weight and / or hydrophilic group equivalent weight, preferably both.

[0097] The alkyl, alkenyl and / or substituted alkyl groups (if any) of formula (III) may independently be straight chain or branched. The substituted alkyl and substituted alicyclic groups (if any) of formula (III) may be substituted with primary and / or secondary amine groups.

[0098] Suitable cycloaliphatic amines may include the following materials or mixtures thereof:

[0099]

[0100]

[0101] Particularly preferred cycloaliphatic amines may include methylcyclohexanediamine, preferably: 2-methylcyclohexane-1,3-diamine; 4-methylcyclohexane-1,3-diamine; or mixtures thereof.

[0102] The amino-functional material may include an amino-functional silane. Suitable amino-functional silanes may include trialkoxy (aminoethylaminopropyl) silanes, alkyldialkoxy (aminoethylaminopropyl) silanes, dialkylalkoxy (aminoethylaminopropyl) silanes, trialkoxy (aminopropyl) silanes, alkyldialkoxy (aminopropyl) silanes, dialkylalkoxy (aminopropyl) silanes, or mixtures thereof. Preferred amino-functional silanes may include trimethoxy(aminoethylaminopropyl)silane, triethoxy(aminoethylaminopropyl)silane, methyldimethoxy(aminoethylaminopropyl)silane, ethyldimethoxy(aminoethylaminopropyl)silane, dimethylmethoxy(aminoethylaminopropyl)silane, dimethylethoxy(aminoethylaminopropyl)silane, trimethoxy(aminopropyl)silane, triethoxy(aminopropyl)silane, methyldimethoxy(aminopropyl)silane, ethyldimethoxy(aminopropyl)silane, dimethylmethoxy(aminopropyl)silane, dimethylethoxy(aminopropyl)silane, or mixtures thereof.

[0103] The amino-functionalized material may include an amino alcohol, preferably wherein one primary amine moiety or one secondary amine moiety is separated from the hydroxyl group by two carbon atoms. Although amino-functionalized materials having hydrophilic groups such as hydroxyl groups are generally not preferred for use in the compositions disclosed herein, amino alcohols having this particular configuration may be useful. Preferred amino alcohols may include 2-(butylamino)ethanol, 1-(cyclohexylamino)2-propanol, 1-(dodecyloxy)-3-[(2-hydroxyethyl)amino]-2-propanol, 3-(dodecylamino)-1,2-propylene glycol, or mixtures thereof.

[0104] Another suitable amino-functional material is 1,3-bis(3-aminopropyl)tetramethyldisiloxane.

[0105] Spice materials

[0106] The perfume premix composition comprises perfume materials. Such materials are ideally formulated in the final product to provide a pleasant fragrance and / or mask unpleasant odors when used.

[0107] The fragrance material may comprise one or more fragrance raw materials ("PRMs"). One or more of the fragrance raw materials may comprise an aldehyde moiety, a ketone moiety, or a combination thereof. Without wishing to be bound by theory, it is believed that PRMs having an aldehyde or ketone moiety may interact with the amine moiety of the amino-functionalized materials (and aminosilicone polymers, if present) described herein in a manner that results in improved fragrance deposition and / or performance in consumer products. In addition, it is believed that PRMs having certain structures are more likely to perform better than other PRMs.

[0108] In general, as used herein, the term "fragrance raw material" (or "PRM") refers to a compound having a molecular weight of at least about 100 g / mol, and which can be used alone or with other fragrance raw materials to impart an odor, aroma, flavor or fragrance. Typical PRMs include alcohols, ketones, aldehydes, esters, ethers, nitrites and olefins, such as terpenes, among others. Lists of common PRMs can be found in various references, such as "Perfume and Flavor Chemicals", Volumes I and II; Steffen ArctanderAllured Pub. Co. (1994) and "Perfumes: Art, Science and Technology", Miller, PM and Lamparsky, D., Blackie Academic and Professional (1994).

[0109] PRMs can be characterized by their boiling point (BP) measured at normal pressure (760 mmHg), and their octanol / water partition coefficient (P), which can be described in terms of logP, as determined according to the test methods below. A fragrance having multiple PRMs characterized by different boiling points and / or logP may be desirable, for example, to provide fragrance benefits at different contact points during normal use.

[0110] As described above, one or more of the fragrance raw materials may comprise an aldehyde moiety, a ketone moiety, or a combination thereof. The one or more fragrance raw materials may comprise an aldehyde moiety. The one or more fragrance raw materials may comprise a ketone moiety.

[0147] It has been found that fragrance raw materials having these characteristics and / or structures (e.g., those described in groups a.-d.) perform surprisingly well in compositions according to the present disclosure, as evidenced by relatively high headspace measurements on treated fabrics, compared to other PRM structures. In addition, it is believed that vanillin and / or ethyl vanillin (described in group e. in the last column above) also perform quite well in the methods and compositions of the present disclosure, even though such performance may not be substantially indicated by the headspace analysis method of the present invention.

[0149] As described above, it is believed that the aldehyde and / or ketone moieties of the one or more fragrance raw materials associate with the amine moieties of the aminofunctional material, and potentially with the amine moieties of the aminosilicone polymer (if present). Therefore, it may be desirable to provide the components at a level where the ketone / aldehyde moieties and the amine moieties are in molar amounts that are appropriately close to each other. For example, if the total number of moles of primary and secondary amine moieties present in the composition provided by the aminosilicone polymer (if any) and the aminofunctional material is "X", and if the total number of moles of aldehyde moieties and / or ketone moieties (preferably aldehyde moieties) present in the composition provided by the one or more fragrance raw materials is "Y", then the ratio of X:Y is from about 2:1 to about 1:10, preferably from about 2:1 to about 1:5, more preferably from about 2:1 to about 1:2, more preferably from about 1.5:1 to about 1:1.5, more preferably from about 1:1 to about 1:1.5.

[0180] The compositions of the present disclosure may include rheology modifiers and / or structurants. Rheology modifiers can be used to "thicken" or "thin down" a liquid composition to a desired viscosity. Structurants can be used to promote phase stability and / or suspend or inhibit the aggregation of particles or droplets in a liquid composition, such as droplets of an emulsion as described herein. Suitable rheology modifiers and / or structurants can include non-polymeric crystalline hydroxyl-functionalized structurants (including those based on hydrogenated castor oil), polymeric structurants, cellulose fibers (e.g., microfibrillated cellulose, which can be derived from bacteria, fungi or plant sources, including from wood), diamido gelling agents, or combinations thereof.

[0181] The consumer product composition prepared by the method described herein may include free fragrance. In order to provide wider and more diverse fragrance characteristics, it may be desirable to include fragrance raw materials that are not present in the silicone emulsion in the free fragrance of the consumer product composition, and / or vice versa. For example, when the silicone emulsion includes one or more fragrance raw materials comprising an aldehyde portion, the free fragrance of the consumer product composition may include one or more fragrance raw materials that do not include an aldehyde portion. Similarly, when the silicone emulsion includes one or more fragrance raw materials that include a ketone portion, the free fragrance of the consumer product composition may include one or more fragrance raw materials that do not include a ketone portion. Free fragrance may include fragrance raw materials that include an aldehyde portion, fragrance raw materials that do not include an aldehyde portion, fragrance raw materials that include a ketone portion, fragrance raw materials that do not include a ketone portion, or mixtures thereof.

[0182] The consumer product composition may include a carrier material. The carrier material may be selected from the group consisting of water, silicon dioxide, zeolite, carbonate, polyvinyl alcohol, polyethylene glycol, sodium acetate, sodium bicarbonate, sodium chloride, sodium silicate, polypropylene glycol polyoxyalkylene, polyethylene glycol fatty acid esters, polyethylene glycol ethers, sodium sulfate, starch, and mixtures thereof. The carrier material may be selected based on the desired final form of the consumer product; for example, a liquid product may use water as a carrier, while a powder or granular product may use carbonate or polyethylene glycol (PEG).

[0183] The base composition may be in liquid form. The base composition may contain water. The base composition may contain from about 1% to about 99%, preferably from about 5% to about 98%, or from about 10% to about 95%, or from about 50% to about 95%, or from about 60% to about 95%, or from about 75% to about 95% water by weight of the base composition.

[0184] The consumer product composition may be in liquid form. The consumer product composition may contain water. The consumer product composition may contain water from about 1% to about 99%, preferably from about 5% to about 98%, or from about 10% to about 95%, or from about 50% to about 95%, or from about 60% to about 95%, or from about 75% to about 95%, by weight of the consumer product composition. Certain unit dose formulations may have relatively low amounts of water so as not to dissolve the water-soluble film; for example, the composition may contain no more than about 20%, or no more than about 15%, or no more than about 12%, or no more than about 10% water by weight of the composition. The perfume premix of the present disclosure may be particularly useful in liquid compositions containing relatively high amounts of water, because it is believed that the hydrophobicity of the silicone enables the silicone, amino-functionalized materials, and perfume materials to be separated from water and associated in a high water matrix.

[0185] The consumer product composition can be in the form of particles, such as a plurality of particles. A single particle can have a mass of about 1 mg to about 1 g. The emulsion can be dispersed in a water-soluble carrier. The water-soluble carrier can be selected from the group consisting of the following items: polyethylene glycol, sodium acetate, sodium bicarbonate, sodium chloride, sodium silicate, polypropylene glycol polyoxyalkylene, polyethylene glycol fatty acid ester, polyethylene glycol ether, sodium sulfate, starch and mixtures thereof. The water-soluble carrier can be a water-soluble polymer. When in the form of particles, the consumer product composition can include a water-soluble carrier of about 25 wt % to about 99.99 wt % and an emulsion of about 0.01 wt % to about 50 wt % by weight. The particle form can be in the form of beads or lozenges.

[0220] Test Method

[0221] Miscibility Testing - Miscibility in Silicones measured via UV-Vis % Transmittance

[0222] The relative miscibility of the components described herein is determined by measuring the percent transmittance through the sample using a UV-Vis spectrophotometer operating in transmission mode at 480 nm using a 1 cm path length cuvette (VWR 97000-588) according to the following procedure. Suitable instruments include Beckman Coulter DU800, ID#1159577, MV31994, SN#8003432.

[0223] All sample preparation and analysis were performed in a laboratory with an air temperature of 22°C + / - 2°C. The primary siloxane present in the composition was combined with the amino-functionalized amine to be tested (e.g., ethylhexylamine) in a ratio of 9.9:0.1 wt / wt in a glass scintillation vial. The vial was capped and the material was mixed thoroughly for 5 minutes using a benchtop vortex mixer set to its highest speed. If two or more distinct layers of material were clearly visible in the vial by the naked eye after mixing, the miscibility of the test material was considered indeterminate via this method. If no distinct layers were visible to the naked eye, analysis was continued.

[0224] Turn on the spectrophotometer lamps and allow them to warm up for 30 minutes before starting the measurement. Set the instrument to collect measurements at 200nm-800nm ​​wavelength in percent transmission (%T) mode. Load all samples into 1 cm path length plastic cuvettes. If bubbles are visible in the cuvette, use a pipette to remove the bubbles before measuring, or allow the bubbles to settle out of the cuvette. Water (if present) should be removed from the mixture (e.g., using a rotary evaporator) before performing the %T measurement.

[0225] The baseline was zeroed (run as a blank) with the corresponding pure silicone sample (see table). The %T was measured for mixtures prepared as described above (eg, mixtures of silicone and amino functional material, or mixtures of silicone + amino functional material + fragrance raw material).

[0226] The % T at 480 nm is reported. Mixtures showing relatively high % T indicate relatively good miscibility.

[0227] Extraction percentage of siloxane (Extraction %)

[0228] To determine the percent extraction (% extraction) of a siloxane polymer, a sample is typically prepared in accordance with the OECD 120 guidelines at a polymer to DI water weight ratio of 1:100. (This method is substantially based on the OECD 120 guidelines as of the first filing date of this disclosure; the OECD 120 guidelines should be used to fill in any gaps in the method, if any.) About 0.2 g of the siloxane polymer is spread evenly on the bottom of a 250 mL polypropylene three-inverted cup, spreading over the total surface area of ​​the entire bottom of the beaker. 20 mL of DI water is pipetted into the cup containing the polymer, taking care not to disturb the polymer layer at the bottom. The beaker is covered with parafilm and placed on an orbital shaker at very low speed (simulating gentle movement of ambient water) at room temperature (about 21° C.) for 24 hours and 6 days. Each polymer is prepared in duplicate for each time point.

[0229] After the designated time, a 10 mL aliquot of water from each beaker was pipetted into a 15 mL centrifuge tube containing 300 uL tetrahydrofuran (THF) and 50 μL 100 ppm yttrium (aq.) (In some cases dilution with DI water may be required to stay within calibration range).

[0230] Samples were analyzed by Inductively Coupled Plasma Optimal Optical Emission Spectroscopy (ICP-OES) against an external calibration curve for inorganic silicon or against a calibration curve for the siloxane polymer tested. Data were reported in polymer equivalents by converting the inorganic silicon to polymer equivalents using the silicon content of each polymer or directly from the polymer calibration curve.

[0231] After a given period of time (e.g., 24 hours and / or 6 days), the percent extraction (% extraction) of each polymer was calculated from the mass of polymer equivalent measured in the aqueous phase relative to the mass of original polymer weighed into three inverted cups. Results are reported as % extraction.

[0232] Determination of Amine Content and % Nitrogen

[0233] The total amine content, primary amine content and / or % nitrogen of the amino-functional siloxane are determined according to the following method. More specifically, the method is used to determine the primary, secondary and tertiary amine values ​​(meq / g), which are defined as the milliequivalents of amine functional groups (primary, secondary and tertiary amines) present in one gram of sample.

[0234] This method is based on the pharmacopoeial method ASTM D2074-07, which should be used to supplement this method when necessary. In Wide Stokes, the sample is dissolved in isopropanol and titrated to the bromophenol blue endpoint using standardized HCl solution.

[0235] The following materials were used: 0.1 N hydrochloric acid in isopropanol (CAS 7647-01-1, 67-63-0; 99.5%; purchased from Fisher Scientific); isopropanol (CAS#67-63-0; 99%; purchased from EMD); phenyl isothiocyanate (CAS#103-72-0; 98%; purchased from Sigma Aldrich); salicylaldehyde (CAS#90-02-8; 98%; purchased from Sigma Aldrich); bromophenol blue indicator (0.1 wt % solution in ethanol or isopropanol; purchased from Fisher Scientific).

[0236] Each of the following titrations should be repeated a total of three times. In addition, the titrant volume must be determined empirically. The titrant volume should be between 1 mL and 20 mL. If the titrant volume is less than 1 mL, more sample is weighed. If the sample is greater than 20 mL, less sample is weighed. A burette such as a Metrohm Dosimat 775 or equivalent can be used in the titration. Regarding the yellow endpoint of the titration - the yellow may fade back to green, but if it is a bright transparent yellow, this will be ignored if the additional 0.1 N HCl does not change the original color.

[0237] A. Titration of Total Amine Content

[0238] If the sample is not liquid, melt the sample in a water bath (usually 100% active). Mix thoroughly and accurately weigh 0.5 g to 1.0 g into a 250 mL conical flask (wide mouth; alkali resistant). Record the weight to four decimal places.

[0239] Add 50 mL of isopropanol to the flask. Add 0.5 mL of bromophenol blue indicator. Titrate with 0.1 N HCl solution while vortexing until it reaches a yellow endpoint. Record the volume of HCl used as V 1,2,3 .

[0240] B. Titration of Secondary and Tertiary Amine Content

[0241] If the sample is not liquid, melt the sample in a water bath (usually 100% active). Mix thoroughly and accurately weigh 1.0 grams into two 250 Erlenmeyer flasks. Record the weight to four decimal places. Label the flasks S and T. Add 50 mL of isopropanol to each flask.

[0242] Add 1 mL of salicylaldehyde to flask S. Stir the solution (with a magnetic stir bar) for 30 minutes. Add 0.5 mL of bromophenol blue indicator solution and titrate with 0.1 N HCl to a yellow endpoint while stirring. Record the volume of HCl used as V. 2&3 .

[0243] Add 1 mL of phenyl isothiocyanate to flask T. Stir the solution (with a magnetic stir bar) for 30 minutes. Add 0.5 mL of bromophenol blue indicator solution and titrate with 0.1 N HCl to a yellow endpoint while stirring. Record the volume of HCl used as V3.

[0244] C. Calculation of amine content

[0245] The variables in the calculations described below correspond to the following:

[0246] V: HCl required for sample titration, in mL

[0247] N: Normality of HCl solution

[0248] S: Sample weight, in grams (g)

[0249] meq / g: milliequivalent / gram

[0250] Total: total amine value

[0251] AS: Amine value of secondary and tertiary amine groups

[0252] TA: Tertiary amine value

[0253] Based on the measurements obtained in connection with the above titrations, the following calculations were used to determine the various amine contents.

[0254]

[0255]

[0256]

[0257] Secondary amine value = (AS-TA)

[0258] Primary amine value = (Total-AS)

[0259] D. Calculation of Nitrogen Weight %

[0260] To determine the weight % nitrogen in the amino-functional siloxane based on the amine content, the following calculation is used.

[0261] The weight percent of nitrogen in the compound can be calculated from the amine value (in meq / g) as follows:

[0262] (Amine value / 1000) x (MW of nitrogen) x 100 = wt% nitrogen

[0263] For example, the amine value of dimethylethanolamine is 11.2 (meq / g). Its nitrogen weight percentage (15.7 weight %) is as follows:

[0264] (11.2 / 1000) x (14.01) x 100 = 15.7 wt% nitrogen

[0265] The table below shows the weight % nitrogen and equivalent amine value.

[0266] Weight% Nitrogen Amine value (meq / g) 0.1 0.071 0.2 0.14 0.3 0.21 0.5 0.36 0.7 0.50 0.8 0.57 1.0 0.71 1.5 1.07 2.0 1.43 2.5 1.78 3.0 2.14 3.5 2.50

[0267] If the amino-functional material contains nitrogen atoms other than in the form of primary, secondary and / or tertiary amines, the nitrogen content as a weight percent can be determined according to methods known to those of ordinary skill in the art.

[0268] E. Standard

[0269] To confirm the quality control of the method, a suitable standard can be run - for example dimethylethanolamine (tertiary amine; 99.5%; purchased from Sigma Aldrich). For this particular amine, the total and tertiary amine content should be 11.2 ± 0.2 meq / g. The primary and secondary amine content should be < 0.1 meq / g.

[0270] Viscosity test method

[0271] The following test method is used to determine the viscosity of amino-functional silicones and / or emulsions containing such silicones.

[0272] A preliminary estimate of the sample viscosity at 25°C was used to select the appropriate instrument geometry used during the final viscosity measurement analysis, which was performed on an AR-G2 model rheometer (manufactured by TA Instruments Corp. (New Castle, Delaware, USA)). A preliminary estimate of the sample viscosity can be obtained by using a Brookfield viscometer (Brookfield Engineering Laboratories Inc. (Middleboro, Massachusetts, USA)). The geometry selection for use on the AR-G2 rheometer was determined according to the following table:

[0273]

[0274] The geometry is attached to the instrument, the instrument is marked, the gap distance is zeroed, and the instrument temperature is set to 25°C. When parallel plates are used, the measurement mode is selected to be a rigid mode, or when a couett cup and bob geometry is used, the measurement mode is selected to be a soft mode. The sample material is mounted in a sample fixing geometry such as a substrate. The minimum gap distance allowed between the substrate and the selected geometry is 10 times the diameter of the largest common particle present in the sample. If there are common particles with a diameter greater than 100 μm (as determined by a microscope) in the sample, the gap value is set to 10 times the diameter of the largest common particle, otherwise the gap distance is set to a default value of 1000 μm (i.e. 1 mm). The selected geometry is lowered to an appropriate gap, and any excess sample material is trimmed off using a plastic tool. The sample material is balanced with the temperature of the instrument. Three rheological measurements are analyzed using the following selections and settings, i.e., flow rate curve, stress sweep, and frequency sweep:

[0275] Flow rate curve: select step flow rate from 0.01 to 100; ten-fold scan points 10; shear stress constant time 20; take the average of the last 10 times.

[0276] Stress sweep: Set the stress range to 0.01Pa to 100Pa; set the frequency to 1rad / s.

[0277] Frequency Sweep: Set the angular frequency range from 0.1 to 100.

[0278] To ensure that the analysis was conducted within the linear viscoelastic region, the stress value was set to one third of the stress value that existed when G' began to drop during the previous stress sweep analysis.

[0279] Report the viscosity value of the test material obtained at 25°C, for example at 0.1 rad / s.

[0280] Particle / droplet size

[0281] The droplet size of the silicone compounds was analyzed in emulsion form and in fabric softeners using a Horiba Partica Laser Scattering Particle Size Distribution Analyzer LA-950V2 with a static quartz cell and operated according to the manufacturer's instructions.

[0282] HLB value of nonionic surfactants

[0283] Nonionic surfactants can be classified by the balance between the hydrophilic and lipophilic parts of the surfactant molecule. The hydrophilic-lipophilic balance (HLB) scale, designed by Griffin in 1949, is a scale of 0-20 (20 being hydrophilic) that is used to characterize the properties of surfactants. The HLB of a surfactant can be calculated as follows:

[0284] HLB=20*Mh / M

[0285] Wherein Mh is the molecular weight of the hydrophilic portion of the molecule and M is the molecular weight of the entire molecule, giving a result on a scale of 0 to 20. An HLB value of 0 corresponds to a completely lipophilic / hydrophobic molecule, while a value of 20 corresponds to a completely hydrophilic / lipophobic molecule. See Griffin, WC Calculation of HLB values ​​of Nonionic Surfactants, J. Soc. Cosmet. Chem. 1954, 5, 249-256. HLB values ​​for commonly used surfactants are readily available in the literature (e.g., HLB index in McCutcheon's Emulsifiers and Detergents (MC Publishing Co., 2004)). The HLB value of a surfactant mixture can be calculated as a weighted average of the HLB values ​​of the surfactants.

[0286] Fabric treatment methods

[0287] Test fabrics were treated with the fabric conditioning composition in a micro-cleaner according to the following procedure.

[0288] Five full-size cotton towels (30 cm x 30 cm) were used per test group (or their equivalents: for example, ten half-size towels or twenty quarter-size towels). The towels were pre-treated with three cycles of liquid detergent and fabric softener (both fragrance-free).

[0289] Weigh the desired amount of detergent doses into a plastic cup and secure with a lid so that the detergent dose per treatment for each cycle is 9.98 g (+ / - 0.02 g). For example, if a five-treatment wash cycle is run, five doses of detergent will be required, one for each treatment. Repeat the same process with the liquid fabric softener sample so that each dose per treatment is 5.68 g (+ / - 0.02 g).

[0290] For this test, the following processing conditions were used:

[0291] Machine Type: Micro washer (designed to simulate top loading conditions)

[0292] Machine cycle: 80spm (normal)

[0293] Washing temperature: about 30.6℃(87℉)

[0294] Rinse temperature: about 15.6℃(60℉)

[0295] Water hardness: about 100ppm (6gpg)

[0296] Washing time: 12min

[0297] Rinse time: 2min

[0298] Water volume: 2 gallon fill (~8L)

[0299] Drying type: Electric

[0300] Turn on the mini washer and water mixing station. Set up the water mixing station using the water specifications described above. Fill each drum of the mini washer to the 2-gallon line and add detergent to each drum individually while the drums are filling. Rinse the cup with the water entering the drum so that all the detergent is added to the drum and well dispersed throughout the drum. Once the drum is full of water and dispersed detergent, add fabrics and set the agitation time to 12 minutes. At the end of the agitation time, set the dehydration timer to 2 minutes to dehydrate the water out of the drum. Once the dehydration cycle is complete, remove the fabrics from each drum, ensuring that each fabric bundle remains separated from each other. Start the filling cycle again using the water specification for the rinse cycle to the 2-gallon line (the water mixing station should automatically switch to the rinse water specification). During the filling cycle, add a dose of liquid fabric softener to each drum individually. Ensure complete addition and dispersion of the liquid fabric softener composition by rinsing the measuring cup with the introduced water. Once the drum is full of water and dispersed fabric softener, the fabrics can be added back to each corresponding drum. Set the agitation cycle to 2min and allow to run. After agitation is complete, set the spin cycle to 2 minutes to extract all the water. After the spin cycle is complete, place each fabric bundle in a separate electric dryer and dry on the high / cotton setting. Once the fabrics are dry, place them in a constant temperature / constant relative humidity chamber set to 75F and 50% relative humidity for at least 4 hours (preferably overnight) to equilibrate.

[0301] Headspace analysis on fabrics

[0302] To prepare treated fabrics for analysis, a 2.54 cm x 5.08 cm (1 inch x 2 inch) cotton swatch was cut from a cotton towel prepared and treated according to the method described above. Each cotton swatch was placed in a 20 mL headspace vial. The vials were equilibrated for an additional four hours in a humidity and temperature controlled room (21°C / 50% humidity). After four hours, the vials were capped and analyzed by headspace solid phase microextraction / gas chromatography / mass spectrometry.

[0303] The equipment used for the analysis was as follows: a gas chromatograph 7890B equipped with a mass selective detector (5977B) (MSD) and a Chemstation quantitation package; a Gerstel multifunctional sampler equipped with a solid phase microextraction (SPME) probe or similar system; a divinylbenzene / Carboxen / polydimethylsiloxane SPME fiber (or similar fiber) obtained from Supleco part number 57298-U; a column, 30 m×0.25 mm nominal diameter, 0.25 μm film thickness, J&W 122-5532UI DB-5; and a 20 mL headspace vial.

[0304] The Gerstel autosampler parameters were as follows: SPME—from incubator; incubation temperature—65°C; incubation time—10.00 min sample parameters; vial penetration—22.00 mm; extraction time—5.00 min; injection penetration—54.00 mm; desorption time—300 s.

[0305] GC oven parameters for pre-SS inlet He were as follows: Mode—Splitless; Heater—270°C; GC Run Time—14.28 min. For Oven: Initial Temperature—40°C; Hold Time—0.5 min; Heating Program—Rate 17°C / min, Temperature 270°C, Hold Time 0.25.

[0306] The MSD parameters are as follows: run in scan mode with a minimum range of 35 to 350 m / z; calibration curve generated from standard fragrance materials; Chemstation software (or similar quantitative software) calculates the amount using the quantitative software for each fragrance component.

[0307] Example

[0308] The examples provided below are intended to be illustrative in nature and not intended to be limiting.

[0309] Example 1. Properties of Certain Siloxane Polymers

[0310] The following table provides properties of certain siloxane polymers. The siloxanes with the same number ("Siloxane Numbers") in Table 1A, Table 1B, and Table 1C correspond to each other. Some of these siloxanes (e.g., Siloxane Numbers 7-10) may be outside the range of siloxanes that can be used in the premix and / or consumer product compositions of the present invention. For example, the amine content and / or % extraction may be relatively too high, or the molecular weight may be too low, which may be related to relatively large solubility in water.

[0311] Table 1A.

[0312]

[0313]

[0314] In Table 1B, the variables (R1-R4, X, Z) and the indices (j, k, m) correspond to the corresponding parts in formula (I) and formula (II), as described in more detail above in the section related to siloxanes. Siloxane No. 1 is a siloxane according to formula (I); Siloxane Nos. 2-10 are siloxanes according to formula (II).

[0320]

[0321] Example 2. Compatibility of Certain Siloxane Polymers and Amino-Functionalized Materials

[0322] In this experiment, different combinations of siloxane polymer and amino-functional material (at a 99:1 weight ratio) were tested according to the Miscibility Test provided in the Test Methods section above. A description of the siloxane polymer is provided in Example 1 above.

[0323] Table 2 shows the results of the compatibility test for each of the following combinations. Generally speaking, relatively higher %T values ​​show better compatibility and are preferred. More specifically, %T values ​​equal to or greater than 90 are most preferred, followed by %T of 60 to less than 90, followed by %T of about 40 to less than 60.

[0324] Table 2.

[0325]

[0326] As shown in Table 2, different amino-functional materials can have different miscibility with different siloxanes, as evidenced by different %T values; see, for example, methylcyclohexyldiamine (amino-functional material #2). In addition, certain amino-functional materials have low miscibility with the tested siloxanes, as evidenced by low %T values; see, for example, PEI-800Mw (polyethyleneimine polymer with a molecular weight of about 800), which may not be suitable for use in a fragrance premix composition according to the present disclosure (at least not in combination with the tested siloxanes).

[0327] Example 3. Miscibility of Certain Siloxane Polymers, Amino-Functionalized Materials, and PRMs

[0328] In this experiment, different combinations of silicone polymers, amino-functional materials, and fragrance raw materials containing aldehyde moieties (at a weight ratio of 99:1:1; ternary system) were tested according to the miscibility test provided in the Test Methods section above. A description of the silicone polymer is provided in Example 1 above.

[0329] Table 3 shows the results of the miscibility testing for each of the following combinations. In general, relatively higher %T values ​​show better miscibility and are preferred, as described in Example 2.

[0330] Table 3.

[0331]

[0332] *DMS-T31 + cyclamal has been found to be relatively turbid, leading to misleading results when used as a blank. (Cyclamal includes aromatic rings and has reduced miscibility with PDMS.)

[0333] As shown in Table 3, different ternary systems can have different miscibility, as evidenced by the % T values. Furthermore, even when the siloxane and amino-functional materials are reasonably miscible, the addition of a PRM can have a detrimental effect; for example, see methylcyclohexyldiamine (amino-functional material #2) in Table 2 Group A vs. Table 3 Group A.

[0334] Also note that, for example, PEI-800Mw has relatively low miscibility in Groups A and B, as evidenced by the low %T values. %T is relatively high in Group C, but the siloxane (DMS-A11) has a solubility that may not be desirable (as evidenced by the amine value and / or % extraction).

[0335] Example 4. Effect of PRM Selection on Miscibility

[0336] This experiment shows the relative impact that the selection of certain fragrance raw materials may have on the overall miscibility of the ternary system (siloxane, amino-functionalized material and fragrance raw material). Each group uses the same siloxane polymer (DMS-T31) and different fragrance selections (none, cyclamal or privet aldehyde); according to the miscibility test provided above, each group tests a mixture with four amino-functionalized materials (e.g., %T at 480nm compared to the blank). The structures of cyclamal (i.e., 3-(4-isopropylphenyl)-2-methylpropanal) and privet aldehyde (i.e., 2,4-dimethylcyclohex-3-ene-1-carboxaldehyde) are provided below.

[0337]

[0338] The results are provided in Table 4. In general, relatively higher %T values ​​indicate better miscibility and are preferred, as described in Example 2.

[0339] Table 4.

[0340]

[0341] *Ligustral is non-aromatic and relatively soluble in PDMS, so the binary system can be used as a blank; compare to Cyclamal discussed in previous examples.

[0342] The selection of one PRM relative to another can have an impact on the miscibility of the ternary system as shown in Table 4. Compare, for example, Groups A, B, and C of methylcyclohexyl diamine (amino functional material #2) in Table 4.

[0343] Likewise, the %T values ​​for the tests including PEI-800Mw were relatively low, indicating low suitability for use in fragrance premix compositions according to the present disclosure.

[0344] Example 5. Exemplary Flavor Premix Formulation

[0345] Table 5 provides an exemplary fragrance premix formulation that can be incorporated into a consumer product. Amounts are provided as weight percent based on the weight of the premix.

[0350] 3 Ethyl vanillin, vanillin, heliotropin, and lilysinal are contained, each selected such that each PRM is present in an amount to provide an equal molar aldehyde moiety.

[0351] Example 6. Exemplary Methods for Preparing a Fragrance Premix Composition and Subsequent Formulation into a Consumer Product

[0352] A. Fragrance Premix Composition (Non-emulsion)

[0353] 56.7 grams of amino-functional siloxane were provided. The amino-functional siloxane was KF-861 provided by Shin-Etsu Chemical Co., Ltd. and had the following structure:

[0354]

[0355] 56.7 grams of the amino-functional siloxane were thoroughly mixed with 3.4 grams of Baxxodur EC 210 (supplied by BASF Corporation) using an IKA overhead mixer set at 250 rpm.

[0356] The following fragrance aldehydes were mixed together to prepare a "Lilysvalerate blend" in the proportions shown in Table 6. The weight (gram) proportions were chosen to provide equal molar ratios of the aldehyde moieties.

[0357] Table 6.

[0358] Lily of the valley aldehyde blend Weight(g) MW(g / mol) mol equivalent Lilial 3.54 204.313 0.0173 0.25 Cyclamal 3.29 190.28 0.0173 0.25 Sea Breeze Aldehyde 3.29 190.28 0.0173 0.25 Conosine aldehyde 3.08 178.23 0.0173 0.25

[0359] 13.2 g of the lilysaldehyde blend mixture was added to the amino-functional siloxane / Baxxodur EC 210 mixture and mixed thoroughly using overhead mixing with a four-blade impeller for 15 minutes.

[0360] B.Consumer Products

[0361] The fragrance premix composition (73.3 grams) is mixed with 1806.7 grams of molten polyethylene glycol (Pluriol E 8000 Prill provided by BASF Corporation) and 120.0 grams of fragrance. The blend is mixed and solidified into consumer product particles having an average diameter of about 0.3 cm to about 1.5 cm and / or an average mass of about 1 mg to about 1 g.

[0362] The resulting consumer product is a plurality of particles suitable for addition to the wash cycle of an automatic fabric washing machine, optionally in combination with a laundry detergent. When the consumer product is diluted with water, a plurality of droplets (believed to contain a premix of silicone polymer, amino-functional material and PRM) having an average diameter of about 1 micron to about 10 microns are obtained.

[0363] Example 7. Exemplary method for preparing a fragrance premix composition in emulsion form and subsequently formulating it into a consumer product

[0364] A. Fragrance premix composition (emulsion)

[0365] 56.7 grams of amino-functional siloxane were provided. The amino-functional siloxane was KF-861 provided by Shin-Etsu Chemical Co., Ltd.; the structure was shown in Example 6 above.

[0366] Using an IKA overhead mixer set at 250 rpm, 56.7 grams of the amino-functional siloxane were mixed with 3.4 grams of Baxxodur EC 210 (supplied by BASF Corporation), 1.0 grams of a nonionic emulsifier (Tergitol 15-S-9 supplied by Dow Chemical Company, Midland, MI), and 3.0 grams of a secondary emulsifier (Surfonic L24-9 supplied by Sasol Chemicals, West Lake, LA).

[0367] Slowly add 10 grams of water and mix for 15 minutes. As the viscosity of the mixture increases, slowly increase the mixing speed. Slowly add 15 grams of additional water while mixing for an additional 10 minutes at a speed between 300 rpm-400 rpm. If the viscosity of the mixture decreases, reduce the mixing speed. Slowly add 11 grams of additional water while continuing to mix for an additional 10 minutes. Continue mixing for an additional 30 minutes at a speed of about 250 rpm.

[0368] The resulting amino-functional siloxane / Baxxodur EC210 emulsion can be analyzed for droplet size via Horiba using a static cell.For droplet size measurement, the emulsion is diluted in deionized water to 0.1 wt% emulsion (eg, 0.1 parts by weight emulsion, 99.99 parts by weight DI water).

[0369] 13.2 g of the Lysmeral Blend mixture (see Example 6 above) was slowly added to the amino-functional silicone emulsion with overhead mixing using a four-blade impeller and mixed gently but thoroughly for 15 minutes. The result was a fragrance premix composition.

[0370] B.Consumer Products

[0371] The fragrance premix composition emulsion (113.3 grams) is mixed with 1756.6 grams of molten polyethylene glycol (Pluriol E 8000 Prill provided by BASF Corporation) and 119.8 grams of fragrance. The blend is mixed and solidified into consumer product particles having an average diameter of about 0.3 cm to about 1.5 cm and / or an average mass of about 1 mg to about 1 g.

[0372] The resulting consumer product is a plurality of particles suitable for addition to the wash cycle of an automatic fabric washing machine, optionally in combination with a laundry detergent. When the consumer product is diluted with water, a plurality of droplets (believed to contain a premix of silicone polymer, amino-functional material and PRM) having an average diameter of about 1 micron to about 10 microns are obtained.

[0373] Example 8. Exemplary Method for Preparing a Substantially Clear Fragrance Premix Composition and Subsequent Formulation into a Consumer Product Law

[0374] A. Fragrance Premix Composition

[0375] 56.65 grams of amino-functional siloxane were provided. The amino-functional siloxane was KF-861 provided by Shin-Etsu Chemical Co., Ltd.; the structure was shown in Example 6 above.

[0376] 56.7 grams of the amino-functional siloxane were thoroughly mixed with 3.4 grams of Baxxodur EC 210 (supplied by BASF Corporation) using an IKA overhead mixer set at 250 rpm.

[0377] 13.2 g of the lilysaldehyde blend mixture (see Example 6 above) was added to the aminofunctional silicone / Baxxodur EC 210 mixture and mixed thoroughly with overhead mixing using a four-blade impeller for 15 minutes. The cloudy fragrance premix composition was made substantially clear via rotary evaporation at 40°C under reduced pressure.

[0378] B.Consumer Products

[0379] The substantially clear fragrance premix composition is mixed with 1806.7 grams of molten polyethylene glycol (Pluriol E 8000 Prill provided by BASF Corporation) and 120.0 grams of fragrance. The blend is mixed and solidified into consumer product particles having an average diameter of about 0.3 cm to about 1.5 cm and / or an average mass of about 1 mg to about 1 g.

[0380] The resulting consumer product is a plurality of particles suitable for addition to the wash cycle of an automatic fabric washing machine, optionally in combination with a laundry detergent. When the consumer product is diluted with water, a plurality of droplets (believed to contain a premix of silicone polymer, amino-functional material and PRM) having an average diameter of about 1 micron to about 10 microns are obtained.

[0381] Example 9. Performance / Headspace Analysis

[0382] The following experiment was conducted to demonstrate the performance benefits associated with the perfume premix composition according to the present disclosure. In summary, two consumer product compositions were prepared - specifically, liquid fabric conditioning compositions. To one consumer product composition, perfume was added as a perfume premix composition according to the present disclosure; to another consumer product composition, neat perfume was added. Fabrics were treated with each consumer product composition, and the headspace above the treated fabrics was analyzed for perfume. Generally, a greater amount of perfume found in the headspace indicates that more perfume is deposited onto and / or released from the fabric.

[0383] Test fragrance blends were prepared by mixing together the following fragrance raw materials in the weight ratios provided.

[0384] PRM weight% Methylnonyl acetaldehyde 32.5 Delta-Damascone 32.5 Glycol 17.5 Methoxyphenyl Butanone 17.5

[0385] A fragrance premix composition was prepared by combining and mixing 78.91 wt % of amino functional silicone KF-867S (supplied by Shin-Etsu Chemical Co., Ltd.), 4.27 wt % of amino functional material Baxxodur EC210 (supplied by BASF Corporation), and 16.82 wt % of the test fragrance blend.

[0386] Fabric conditioning compositions were prepared according to the following procedure. A base fabric conditioning composition was provided containing a mixture of 9.5 wt% of N,N-di(tallowoyloxyethyl)-N,N-dimethylammonium chloride in water. To one sample of the base fabric conditioning composition was added the neat test perfume blend; to another sample was added the perfume premix composition. Both were added in amounts that provided the final fabric conditioning composition with about 0.3% total perfume. The mixture was stirred at 350 rpm for 15 min using an IKA RW 20D S1 stirrer model RW20D-S1 and an IKA R1342 impeller blade. A structurant and a deposition aid were added and the mixture was stirred for 10 min. If necessary, water was added to standardize the concentration of N,N-di(tallowoyloxyethyl)-N,N-dimethylammonium chloride in the test group to 8 wt%, and the mixture was stirred for 5 min. The pH was adjusted to 2-3 with 1N HCl.

[0387] The test fabrics were treated according to the fabric treatment method provided in the Test Methods section. One set of fabrics (Sample 1) was treated with a fabric conditioning composition made from the provided pure test perfume blend. Another set of fabrics (Sample 2) was treated with a fabric conditioning composition made from the perfume premix composition.

[0388] After treatment, the concentration of perfume raw materials on each fabric was determined via headspace analysis on the fabric. The results are provided in Table 7.

[0389] Table 7.

[0390]

[0391] As can be seen in Table 7, fabrics treated with the fabric conditioning composition comprising perfume added as a perfume premix provided more fragrance on the fabric than fabrics treated with the comparative composition wherein the perfume was added as a neat blend (e.g., no silicone / amino functional group / perfume premix).

[0392] Example 10. Emulsion beneficial effects

[0393] In this example, various benefits of a premix in the form of an emulsion according to the present disclosure are shown, including benefits in loading efficiency, droplet size, headspace, and color stability. As discussed in more detail below, an emulsion premix according to the present disclosure is generally preferred with respect to one or more of these beneficial carriers.

[0394] A. Sample emulsion

[0395] Various fragrance emulsions were prepared and tested in the examples that follow. The fragrance blends used in the emulsions are provided in Table 8; the following fragrance raw materials were mixed together in the weight ratios provided.

[0396] Table 8.

[0397]

[0398]

[0399] The fragrance mixture of Table 8 was used to prepare the following emulsions as shown in Table 9. Each emulsion is characterized by a 1:1 molar ratio of amino functional groups to ketone-containing fragrance raw materials. Emulsions 1-3 are comparative examples; Emulsion 4 is an emulsion premix according to the present disclosure.

[0408] The emulsions of Table 9 above were prepared and mixed using substantially the same mixing energy and time. After mixing, the average diameter of the droplets of each emulsion was characterized using a Horiba laser scattering particle size distribution analyzer (Model: LA-950V2). The results are provided in Table 10.

[0409] Table 10.

[0410]

[0411] The results in Table 10 (specifically, Emulsion 4) show that emulsions according to the present disclosure can produce emulsions characterized by relatively small droplet sizes while still containing relatively high amounts of fragrance raw materials. As described above, it is believed that relatively small droplets (e.g., having an average diameter of about 1 micron to about 10 microns, preferably about 1 micron to about 5 microns) are preferred for performance and / or stability reasons.

[0412] In particular, it is noted that Comparative Emulsion 1 and Emulsion 4 carry the same amount of fragrance, but the droplet size is much smaller in Emulsion 4. Additionally, the average droplet diameters of Comparative Emulsion 3 and Emulsion 4 are somewhat similar, but the amount of fragrance carried in Emulsion 4 is greater.

[0413] C. Tablet Performance and Stability

[0414] The emulsions of Table 9 were prepared and incorporated into various granular laundry detergent additives, particularly those similar to those in the form of DOWNYUNSTOPABLES. TM (available from Procter & Gamble Company). In addition, one of these formulations includes the active material of Emulsion 4 added separately (e.g., as a separate component, not as a premix); see Comparative Product 4 below. The emulsion (and separately added material) is included in such amounts so as to deliver 0.55% by weight of fragrance to the final product. The different groups of formulations are provided in Table 11 below.

[0415] The products were used to treat fabrics in a micro-cleaner, and headspace analysis was performed above the treated fabrics to test the perfume delivery performance; larger headspace values ​​(in nmol / L) indicated the presence of relatively more perfume. In addition, color measurements were taken for each product (freshly prepared), and the difference compared to Product 1 was reported as a ΔE value; larger ΔE values ​​indicated a greater color difference from Product 1, which typically has a whitish color. In contrast, larger ΔE values ​​in Products 2-5 were associated with yellowing or even brown coloration.

[0416] Table 11.

[0417]

[0418] As shown in the results in Table 11, Product 5 exhibited the best / most desirable combination of headspace results and color change results. For example, Product 1 (PRM-only control) exhibited relatively desirable color, but also exhibited low headspace results. Product 2 exhibited desirable headspace results, but a relatively high degree of color change. Product 3 exhibited relatively low headspace results and a high degree of color change; in addition, a relatively large amount of emulsion was required to deliver the desired amount of fragrance. Product 4, in which the materials were added separately, exhibited relatively low color change, but also less fragrance in the headspace, compared to Product 5.

[0419] D. Performance and stability in liquid fabric enhancers

[0420] The emulsions of Table 9 were prepared and incorporated into various liquid fabric enhancer products, similar to those in liquid DOWNY TM fabric softener (available from the Procter & Gamble Company). Additionally, one of these formulations included the active of Lotion 4 added separately (eg, as a separate component, rather than as a premix); see Comparative Product 9 below.

[0421] The base liquid softener provided in Table 12 contains about 7 wt% of diester quaternary ammonium softening material and contains no fragrance. Such amount includes emulsion (and separately added materials) so as to deliver 0.30 wt% of fragrance to the final product. The formulations of different groups are provided in Table 12 below.

[0422] The products were used to treat fabrics in a micro-cleaner, and headspace analysis was performed above the treated fabrics to test the perfume delivery performance; larger headspace values ​​(in nmol / L) indicated the presence of relatively more perfume. In addition, color measurements were taken for each product (freshly prepared), and the difference compared to product 6 was reported as a ΔE value; larger ΔE values ​​indicated a greater color difference from product 6, which typically had a whitish color. In contrast, larger ΔE values ​​in products 7-10 were associated with yellowing coloration.

[0423] Table 12.

[0424]

[0425] As shown in Table 12, Product 10 exhibited a desirable combination of headspace data, color data, and a relatively low amount of fragrance premix required to deliver the desired amount of fragrance.

[0426] It is also worth recalling that Comparative Emulsion 2, used to prepare Comparative Product 7, was characterized by a relatively large (and less preferred) average droplet size; see Table 10 above.
