Description

[Technical Field]

[0001] The present disclosure relates to treatment compositions comprising a particular vegetable rosin material and one or more benefit agents, e.g., a fragrance material, where the vegetable rosin material is a particular vegetable rosin ester and / or has particular properties, e.g., a particular softening point, acid number, and / or color rating. The present disclosure also relates to related methods of making and using such compositions. [Background technology]

[0002] Manufacturers of treatment compositions such as liquid fabric softeners have various delivery systems available to facilitate improved delivery of benefit agents. Such systems can take the form of core-shell particles and / or deposition aids such as cationic polymers.

[0003] However, these delivery systems often require synthetic materials, which may not be preferred by today's environmentally conscious consumers. Therefore, manufacturers are constantly seeking naturally derived materials that offer improved performance profiles.

[0004] Rosin-based materials, typically derived from plants such as pine wood, have been disclosed as diluents, carriers, and fixatives in various consumer products. However, their use as delivery agents and / or performance enhancers has not been extensively explored. Additionally, some of these materials are difficult to process or lead to phase instability in the final product. Summary of the Invention [Problem to be solved by the invention]

[0005] There is a continuing need for treatment compositions that include naturally derived benefit agent delivery systems that provide improved performance and / or convenient processing. [Means for solving the problem]

[0006] The present disclosure relates to treatment compositions that include certain vegetable rosin materials.

[0007] For example, the present disclosure relates to a treatment composition comprising a vegetable rosin material, wherein the vegetable rosin material is a vegetable rosin ester material, wherein the vegetable rosin ester material is derived from vegetable rosin and an alcohol, wherein the alcohol comprises (a) 2 to 6 carbon atoms and / or (b) 2 to 6 hydroxyl groups, and wherein the treatment composition further comprises one or more benefit agents, and preferably may include a fragrance material.

[0008] The present disclosure also relates to treatment compositions comprising a vegetable rosin material and one or more benefit agents, wherein the vegetable rosin material is a vegetable rosin ester material, the vegetable rosin ester material comprising an average of about 2 to about 6 moles of ester groups per mole of the vegetable rosin ester material.

[0009] The present disclosure also relates to a treatment composition comprising a vegetable rosin material characterized by at least one, preferably at least two, and preferably all three of the following properties: (a) a softening point of from about 50°C to about 120°C, preferably from about 60°C to about 100°C; (b) an acid number of from about 0 to about 100, preferably from about 0 to about 80, more preferably from about 0 to about 60, more preferably from about 0 to about 40, and even more preferably from about 0 to about 20; and (c) a color rating of from about 1 to about 10, preferably from about 1 to about 8, and more preferably from about 1 to about 6, when rated on the Gardner Standard Color Number Scale, and the treatment composition further comprises one or more benefit agents.

[0010] The present disclosure also relates to a method of treating a surface, preferably a fabric, the method comprising contacting the surface, optionally in the presence of water, with the treatment composition described herein. [Brief explanation of the drawings]

[0011] This patent or application contains at least one photograph developed in color. Copies of this patent or patent application publication with the color photograph(s) will be provided by the Office upon request and payment of the necessary fee.

[0012] The drawings herein are illustrative in nature and are not intended to be limiting. [Figure 1] 1 shows a color photograph of a liquid fabric softener (LFE) product containing a particular plant resinous material. DETAILED DESCRIPTION OF THE INVENTION

[0013] The present disclosure relates to treatment compositions that include certain botanical rosin materials and one or more benefit agents, such as fragrances. As the name suggests, botanical rosin materials are derived from plants, typically pine trees. This makes them attractive as natural or sustainable materials, even if they are subsequently modified or derived.

[0014] It has been discovered that by selecting specific vegetable rosin materials with specific chemical and / or physical properties, the performance of benefit agents can be improved at specific touchpoints. Without being bound by theory, it is believed that certain types of rosin are preferred because they allow for a good balance between establishing strong molecular interactions with specific benefit agents, such as fragrance molecules, while at the same time ensuring sufficient processability and product stability.

[0015] For example, it is believed that strong molecular interactions are important for promoting good delivery efficiency of benefit agents. The molecular interactions are based on the terpene structure present in the vegetable rosin itself. Therefore, preferred resins have (or are chemically modified to have) a structure that favors molecular interactions that bind the rosin and the benefit agent. However, it is further believed that the molecular interactions with the benefit agent should not exceed a certain threshold, because a high level may cause difficulties in the manufacturing process of the product, for example, due to the viscosity of the vegetable rosin or its poor dispersibility in the final product.

[0016] Thus, preferred resins are those that can establish good molecular interactions with the delivery benefit agent while, for example, allowing for good dispersion characteristics in the final product formulation. For example, resins with a low rosin acid content (as evidenced by a relatively low acid number) may be preferred, as they are believed to tend to exhibit good dispersion characteristics. Additionally, rosin esters may be preferred, as their three-dimensional structure is believed to facilitate good benefit agent binding capabilities. Furthermore, hydrogenated resins may also be preferred, as they tend to exhibit resistance to oxidation.

[0017] The components, compositions, and processes of the present disclosure are described in more detail below.

[0018] As used herein, the articles "a" and "an," when used in a claim, are understood to mean one or more of what is claimed or described.

[0026] Treatment Composition The present disclosure relates to treatment compositions comprising certain vegetable rosin materials and one or more benefit agents. The treatment compositions may be useful for treating surfaces such as fabrics, hard surfaces, hair, and / or skin.

[0027] The treatment composition may be a consumer product composition. The consumer product composition may be a fabric care composition, a hard surface cleaning composition, a dish care composition, a hair care composition, a body cleansing composition, or a mixture thereof. The consumer product composition may be a conditioning composition, such as a liquid softener composition or a hair conditioner composition.

[0028] The treatment composition of the present disclosure may be a fabric care composition. Such compositions may be used as a laundry pre-treatment agent, a laundry post-treatment agent, or may be added during the rinse or wash cycle of laundry operations. The fabric care composition may be a fabric detergent composition, a fabric conditioning composition, or a mixture thereof, preferably a fabric conditioning composition. The fabric conditioning composition may include liquid fabric softeners and liquid fabric softener compositions.

[0029] The treatment composition may be in any suitable form, for example in the form of a liquid composition, a granular composition, a hydrocolloid, a single-compartment pouch, a multi-compartment pouch, a dissolvable sheet, a pastille or bead, a fibrous article, a tablet, a stick, a bar, a flake, a foam / mousse, a nonwoven or mixtures thereof, and preferably is a liquid.

[0030] The treatment composition may be in the form of a liquid. The liquid composition may comprise from about 30%, or from about 40%, or from about 50%, to about 99%, or to about 95%, or to about 90%, or to about 75%, or to about 70%, or to about 60% water by weight of the composition. The liquid composition may be a liquid laundry detergent, a liquid fabric conditioner, a liquid dish detergent, a hair shampoo, a hair conditioner, or a mixture thereof.

[0031] The treatment composition may be in the form of a solid. The solid composition may be a powder or granular composition. Such compositions may be agglomerated or spray-dried. Such compositions may comprise a plurality of granules or particles, at least some of which comprise different compositions. The composition may be a powder or granular cleaning composition, which may include bleach. The composition may be in the form of beads or pastilles, which may be pastilles from a liquid melt. The composition may be an extruded product.

[0032] The treatment composition may be in the form of a unit-dose article such as a tablet, pouch, sheet, or fibrous article. Pouch-form unit-dose articles typically include a water-soluble film, such as a polyvinyl alcohol water-soluble film, at least partially enclosing the composition. Suitable films are available from MonoSol, LLC (Indiana, USA). The composition can be enclosed in a single-compartment pouch or a multi-compartment pouch. A multi-compartment pouch may have at least two, at least three, or at least four compartments. A multi-compartment pouch may include compartments arranged side-by-side and / or stacked. The composition contained in the pouch or its compartments may be liquid, solid (such as a powder), or a combination thereof. The pouch composition may have a relatively low amount of water, for example, less than about 20% by weight of the detergent composition, or less than about 15% by weight, or less than about 12% by weight, or less than about 10% by weight, or less than about 8% by weight.

[0033] The treatment composition may be in the form of a spray, for example, dispensed from a bottle via a trigger sprayer and / or an aerosol container equipped with a valve.

[0034] When the treatment composition is a liquid, the composition may be characterized by its viscosity. -1 At 21°C, it is approximately 1 to 1500 centipoise (approximately 1 to 1500 mPa * s), or about 50 to about 1000 centipoise (about 50 to 1000 mPa * s), or approximately 100 to 500 centipoise (approximately 100 to 500 mPa * s), or about 100 to about 200 centipoise (about 100 to 200 mPa * It is disclosed that the composition may have a viscosity of 0.5 wt. s. The relatively low viscosity allows for improved application and / or reduced residue in the dispenser drawer. Viscosity is determined according to the method provided in the Test Methods section below.

[0035] Treatment compositions of the present disclosure may be characterized by a pH of about 2 to about 12, or about 2 to about 8.5, or about 2 to about 7, or about 2 to about 5. Treatment compositions of the present disclosure, preferably in aqueous liquid form, may have a pH of about 2 to about 4, preferably about 2 to about 3.7, and more preferably about 2 to about 3.5. Such pH levels are believed to promote the stability of certain adjuvants, such as conditioning actives (e.g., ester quats). The pH of the composition is measured by dissolving / dispersing the composition in deionized water to form a 10% concentration solution at about 20°C.

[0036] The vegetable rosin material and one or more benefit agents may be present in a weight ratio of from about 5:95 to about 95:5, preferably from about 20:80 to about 80:20, more preferably from about 30:70 to about 70:30, and more preferably from about 40:60 to about 60:40.

[0037] Plant rosin material The treatment compositions and processes described herein contain vegetable rosin materials. It is believed that the performance of the treatment compositions can be improved by selecting specific vegetable rosin materials, such as those characterized by particular properties (e.g., softening point and / or acid number within a particular range), particular chemicals (e.g., rosin esters), or combinations thereof.

[0038] As used herein, "vegetable rosin material" may include vegetable rosin (including resin acids), derivatives of vegetable rosin, or mixtures thereof. The vegetable rosin material of the present compositions and processes may provide performance benefits, for example, by improving deposition and / or promoting stability of benefit agents. Because such materials are derived from natural and / or sustainable sources, known alternatives to the compositions and processes disclosed herein may be more preferable.

[0039] As explained in more detail below, vegetable rosin is typically derived from coniferous trees (class: Pinus), usually pine trees (genus: Pinus). Vegetable rosin, also called "pine resin," is a solid material produced by heating liquid resin to vaporize the volatile liquid terpene components. Vegetable rosin is typically composed of resin acids, such as abietic acid, and related compounds. Vegetable rosin may be further derived, for example, by esterification and / or hydrogenation.

[0040] The compositions of the present disclosure may comprise from about 0.01% to about 10% vegetable rosin material by weight of the composition, from about 0.01% to about 5%, or from about 0.05% to about 3%, or from about 0.1% to about 1% vegetable rosin material by weight of the composition.

[0041] Vegetable rosin materials may be characterized by a softening point. While vegetable rosin materials are typically solid at room temperature, the softening point is a measure of the glass transition temperature associated with these materials. The softening point of a vegetable rosin material is determined according to the method provided in the Test Methods section below.

[0042] The vegetable rosin material may be characterized by a softening point of about 50°C to about 175°C, or about 60°C to about 150°C, or about 75°C to about 125°C. Preferred vegetable rosin materials may be characterized by a softening point of about 50°C to about 120°C, preferably about 60°C to about 100°C. Rosin may need to be softened by heating for incorporation into consumer products. Therefore, for ease of processing and / or energy savings, vegetable rosin materials with relatively low softening points (e.g., less than 125°C) may be preferred for the compositions and processes of the present disclosure. A lower softening point may also be effective in improving the deposition-aiding performance of the vegetable rosin material.

[0043] Vegetable rosin materials may be characterized by their acid number (sometimes referred to as "acid value"). The acid number of a vegetable rosin material is related to the total free acid content of these products. The acid number of a vegetable rosin material is determined according to the method provided in the Test Methods section below.

[0044] The vegetable rosin material may be characterized by an acid number of less than about 175, such as from about 0 to about 175. For the compositions and processes of the present disclosure, it may be preferred to use vegetable rosin materials having a relatively low acid number, such as less than about 125, preferably less than about 100, more preferably less than about 75, even more preferably less than about 50, and more preferably less than about 25, so as to minimize the effect on the final pH of the treatment composition. Preferred vegetable rosin materials may be characterized by an acid number of from about 0 to about 100, preferably from about 0 to about 80, more preferably from about 0 to about 60, more preferably from about 0 to about 40, and even more preferably from about 0 to about 20. Without being bound by theory, it is believed that vegetable rosin materials having a relatively low acid number are also more easily dispersible in the treatment compositions of the present disclosure.

[0045] However, vegetable rosin materials having a relatively high acid number (e.g., from about 125 to about 175, preferably from about 150 to about 175) can be useful, especially if the vegetable rosin material also has a relatively low softening point (e.g., below about 100°C, preferably below about 80°C) and the material is also at least partially hydrogenated.

[0046] The color of the vegetable rosin material may be graded based on the Gardner Color Standard Number, ranging from 1 to 18. To minimize the impact on the final color of the treatment composition, the vegetable rosin material of the present disclosure may preferably have a color rating of from about 1 to about 10, preferably from about 1 to about 8, preferably from about 1 to about 6. The color rating of the vegetable rosin material is determined according to the method provided in the Test Methods section below.

[0047] The most preferred vegetable rosin materials tend to be characterized by a combination of the above properties. For example, the vegetable rosin material may be characterized by at least one, preferably at least two, and preferably all three of the following properties: (a) a softening point of about 50°C to about 120°C, preferably about 60°C to about 100°C; (b) an acid number of about 0 to about 100, preferably about 0 to about 80, more preferably about 0 to about 60; and (c) a color rating of about 1 to about 10, preferably about 1 to about 8, more preferably about 1 to about 6, as rated on the Gardner Color Standard Scale. In particular, the vegetable rosin material may be characterized by a softening point of about 60°C to about 100°C and an acid number of about 0 to about 80, more preferably about 0 to about 60. Vegetable rosin materials having these properties have been found to be particularly effective in improving the performance of associated benefit agents, such as fragrances.

[0048] Plant rosin materials may have an odor. Naturally derived resins have a large amount of terpene compounds. For the compositions and processes of the present disclosure, it may be preferable to select compounds with a relatively small amount of terpene structures and / or odors from naturally derived resins so as not to interfere with the overall perception. On the other hand, if a pine-like fragrance is desired, the presence of terpene structures may be preferable.

[0049] For example, gum rosin may be preferred over tall oil rosin because tall oil rosin may contain sulfur contaminants that adversely affect odor, whereas it may be desirable for vegetable rosin materials to have a detectable odor because the "piney" flavor associated with rosin materials may be common or desirable in certain product compositions.

[0050] Vegetable rosin materials are typically relatively insoluble in water. For example, the plant resin materials of the present disclosure may be characterized by a solubility in deionized water at 22° C. of less than 1 g / L, or less than 100 g / L, or less than 1 g / L, or less than 0.1 g / L, or less than about 0.01 g / L. Without wishing to be bound by theory, it is believed that the relatively insoluble nature of the vegetable rosin materials of the present disclosure contributes to the deposition efficiency and performance of associated benefit agents.

[0051] The vegetable rosin material may be characterized by its density. Typically, the vegetable rosin material has a density of 1.0 kg / dm3 at 25°C. 3 greater than 1.1 kg / dm 3 It is characterized by a density where

[0052] Vegetable rosin materials are typically flammable. For the compositions and processes of the present disclosure, it may be preferable to use a vegetable rosin material with a relatively high flash point, e.g., greater than 190°C, to facilitate easier and safer processing. The flash point of the vegetable rosin material is determined according to the method provided in the Test Methods section below.

[0053] The treatment compositions of the present disclosure may include particles comprising a vegetable rosin material and one or more benefit agents. Such particles can be particularly effective in delivering one or more benefit agents. The particles can be characterized by a volume-weighted median particle diameter of the particles of about 10 microns to about 400 microns, or about 15 microns to about 300 microns, or about 20 microns to about 250 microns, or about 25 microns to about 200 microns, or about 30 microns to about 150 microns, or about 35 to about 125 microns, preferably about 40 to about 100 microns, and more preferably about 50 to about 90 microns. A premix comprising a vegetable rosin material and one or more benefit agents can be a particularly effective means of providing particles to the treatment composition. The volume-weighted median diameter is determined according to the method provided in the Test Methods section below.

[0054] Vegetable rosin and vegetable rosin derivatives (such as rosin esters) and premixes containing such materials are described in more detail below.

[0055] A. Plant rosin The plant rosin material of the present disclosure may include plant rosin. Plant rosin is typically obtainable from plant oleoresin, which may be exuded or otherwise derived from pine trees. The oleoresin may be distilled to remove volatile terpenes, and the remaining solid material is the plant rosin.

[0056] The vegetable rosin may be solid at room temperature. The solid rosin may be relatively translucent and / or glass-like. The vegetable rosin material may have a color ranging from, for example, light yellow to dark brown or black.

[0057] Vegetable rosin is typically a mixture of compounds, primarily composed of resin acids (also called rosin acids). Vegetable rosin may contain at least about 75%, or at least about 80%, or at least about 85%, or at least about 90%, or at least about 95% resin acids by weight of the vegetable rosin. Vegetable rosin may contain from about 75% to about 97%, or from about 80% to about 96%, or from about 85% to about 95%, or from about 90% to about 95% resin acids by weight of the vegetable rosin. The remaining materials may be non-acidic materials.

[0058] Resin acids are typically monocarboxylic acids with three fused rings. Resin acids include, for example, C 19 H 29 The resin acid may be a tricyclic diterpene monocarboxylic acid having a molecular formula such as COOH. The resin acid may include abietic-type acids, pimaric-type acids, plicatic acids, or mixtures thereof. The double bond of abietic-type acids is typically conjugated, while the double bond of pimaric-type acids is typically unconjugated.

[0059] Abietic-type acids may include abietic acid, neoabietic acid, dehydroabietic acid, palustric acid, levopimaric acid, or mixtures thereof. Pimaric-type acids may include pimaric acid, isopimaric acid, sandaracopimaric acid, or mixtures thereof. Structures of these exemplary resin acids are provided in Table A below.

[0060] [Table 1]

[0061] The vegetable rosin may contain an abietic type acid, preferably abietic acid, which has the empirical formula C 19 H 29 It has a COOH group and is also known as abietic acid or sylvic acid. Abietinic acids are typically the main components of vegetable rosins. Vegetable rosins may contain at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 85% by weight of the vegetable rosin of abietic acids, preferably abietic acid.

[0062] Vegetable rosins may be classified according to the source from which they are obtained. For example, vegetable rosins of the present disclosure may be classified as (and include) gum rosin, wood rosin, tall oil rosin, or mixtures thereof. Gum rosin is derived from the resin extrudates of trees or other plants and may be collected by tapping the trees or wounding the trees and collecting and processing the extrudates. Wood rosin may be derived from material collected from pine tree stumps, for example, by solvent extraction and / or distillation. Tall oil rosin is a by-product of the distillation of crude tall oil during the Kraft process of wood pulping when pulping pine trees.

[0063] Suitable plant rosins are, for example, those of Pinus massoniana (baby pine), Pinus elliotti (slash pine), Pinus palustris (longleaf pine), Pinus taeda (loblolly pine), Pinus oocarpa (Mexican yellow pine), Pinus leiophylla (Chihuahua pine), Pinus devoniana (Pino lasio or Michoacam pine), Pinus montezumae (Montesumae pine), P. pinaster (French maritime pine), P. sylvestris (Scotch pine), P. halepensis (P. The pine may be obtained from various pine species such as P. halepensis (Aleppo pine), P. insularis (P. insularis), P. kesiya (P. kesiya), P. strobus (Eastern white pine) or mixtures thereof.

[0064] B. Plant rosin ester The vegetable rosin materials of the present disclosure may include vegetable rosin ester materials (or simply "vegetable rosin esters" as used herein), which may be made by chemically modifying vegetable rosin materials, such as rosin acids, such as abietic acid, through an esterification process.

[0065] Esters of vegetable rosin may be the reaction product of vegetable rosin (e.g., rosin acid) and an alcohol. A sample condensation reaction between three abietic acid molecules and one glycerol molecule is shown below, which results in a rosin ester.

[0066] [ka]

[0067] The vegetable rosin ester material may be derived from vegetable rosin and an alcohol, the alcohol containing (a) 2 to 6 carbon atoms and / or (b) 2 to 6 hydroxyl groups.

[0068] Preferably, the alcohol contains two or more hydroxyl groups and two or more carbon atoms, as rosin esters formed from such alcohols are believed to perform better than those containing one ester group and / or one carbon (e.g., methyl esters). The alcohol may contain (a) 2 to 6 carbon atoms and (b) 2 to 6 hydroxyl groups. The alcohol from which the vegetable rosin ester material is derived may preferably contain 2 to 5 hydroxyl groups, more preferably 3 to 5 hydroxyl groups, and more preferably 3 to 4 hydroxyl groups. The alcohol from which the vegetable rosin ester material is derived may contain 2 to 5 carbon atoms, more preferably 3 to 5 carbon atoms. The alcohol from which the vegetable rosin ester material is derived may be selected from the group consisting of glycerol, pentaerythritol, and mixtures thereof, preferably glycerol.

[0069] The alcohol used in the esterification reaction may have a relatively low molecular weight. For example, the alcohol may have a molecular weight of about 32 to about 300 daltons, preferably about 32 to about 200 daltons, more preferably about 32 to about 150 daltons, and even more preferably about 90 to about 150 daltons. Without wishing to be bound by theory, it is believed that rosin esters formed from lower molecular weight alcohols may be characterized by a relatively lower softening point and / or a lower acid number compared to rosin esters formed from higher molecular weight alcohols, which may result in better processability and / or performance.

[0070] The vegetable rosin ester material may contain an average of about 2 to about 6 moles of ester groups per mole of vegetable rosin ester material.

[0071] The alcohol used in the esterification reaction may be glycerol or pentaerythritol, and therefore the vegetable rosin ester material may be a glyceryl rosin ester, a pentaerythrityl rosin ester, or a mixture thereof.

[0072] The vegetable rosin ester material may be characterized by one or more, preferably two or more, and more preferably all three of the following properties: (a) a softening point of about 50°C to about 120°C, preferably about 60°C to about 100°C, and / or (b) an acid number of about 0 to about 100, preferably about 0 to about 80, more preferably about 0 to about 60, and / or (c) a color rating of about 1 to about 10, or preferably about 1 to about 8, more preferably about 1 to about 6, when rated on the Gardner Color Standard Scale.

[0073] The vegetable rosin ester material may be derived from gum rosin, wood rosin and / or tall oil rosin, preferably gum rosin. The vegetable rosin ester material may include gum rosin esters.

[0074] The vegetable rosin ester material may be at least partially hydrogenated.

[0075] C. Other plant rosin derivatives The vegetable rosin material may contain other vegetable rosin derivatives in addition to or as an alternative to the vegetable rosin esters. In some cases, the vegetable rosin esters may be further derivatized. Such derivatives may be produced by processes such as hydrogenation, dimerization, polymerization, saponification, or mixtures thereof.

[0076] The vegetable rosin material may include hydrogenated rosin. Given that many vegetable rosin compounds (e.g., rosin acids) are unsaturated, they tend to be oxidatively unstable and may change color upon storage. Hydrogenation helps stabilize the rosin and can reduce undesirable color changes. Furthermore, hydrogenated rosin tends to have a lighter color than the parent rosin, which allows for more formulation and aesthetic flexibility.

[0077] The vegetable rosin and / or rosin acids may be partially or fully hydrogenated. Below are sample reactions for partially and fully hydrogenating abietic acid:

[0078] [ka]

[0079] The treating composition may include an at least partially hydrogenated, preferably fully hydrogenated, vegetable rosin material.

[0080] The vegetable rosin derivatives may be hydrogenated or esterified, for example, the vegetable rosin derivative may be a hydrogenated glyceryl ester.

[0081] The vegetable rosin material may include dimerized vegetable rosin. Dimerization may be useful for increasing the softening point and / or stability of the rosin acid. A sample dimerization reaction for abietic acid is shown below:

[0082] [ka]

[0083] Because it is difficult or even impossible to completely dimerize a rosin sample, rosin dimers often exist along with non-dimerized rosin acids, which may be further esterified.

[0102] One or more benefit agents may be combined with the vegetable rosin material in a premix, which may be added to the base composition to make the treatment composition of the present disclosure. The base composition may include adjunct ingredients, as described in more detail below. Thus, the treatment composition of the present disclosure may include a premix including the vegetable rosin material and one or more benefit agents. composition may be formed by a method comprising adding a premix to a base composition, the premix comprising the vegetable rosin material and one or more benefit agents, and the base composition comprising the adjunct ingredients.

[0103] The premix may comprise from about 1% to about 99% vegetable rosin material by weight of the premix. The premix may comprise from about 1% to about 99% benefit agent by weight of the premix. The premix may comprise a weight ratio of vegetable rosin material to benefit agent of from about 1:99 to about 99:1, preferably from about 5:95 to about 95:5, more preferably from about 10:90 to about 90:10, more preferably from about 20:80 to about 80:20, more preferably from about 30:70 to about 80:20, and more preferably from about 40:60 to about 80:20. It is believed that performance benefits increase with a higher vegetable rosin to benefit agent weight ratio.

[0104] The premix may include an emulsifier.

[0107] The premix can be made by heating the vegetable rosin material. The vegetable rosin material can be heated to a temperature above the softening point of the vegetable rosin material. The premix can be made by combining and mixing the heated vegetable rosin material with a benefit agent.

[0108] To benefit the homogeneity of the premix, mixing may be performed in a heated oil bath set at a temperature equal to the softening point of the vegetable rosin material. As the sample becomes homogeneous, the temperature can be gradually reduced. This helps reduce the risk of loss of volatile materials (e.g., evaporation of volatile PRMs).

[0109] Processing aids (e.g., emulsifiers described above) can be added at any suitable time. Preferably, the emulsifier is combined with the vegetable rosin material before adding the benefit agent (e.g., fragrance), if present. The order of addition is believed to improve the ease of homogenization of the mixture.

[0110] In addition to or as an alternative to heating, the vegetable rosin material may be ground into small particles which are then mixed with the benefit agent.

[0111] Once made, the premix may be stored at ambient temperature. However, when the premix is used to make a final product composition, the premix may be heated, for example, to about 60°C, before being injected into the final product or otherwise combined with the base composition. This heating step is most likely to be useful when the premix features a relatively high weight ratio of rosin to benefit agent (e.g., fragrance) (e.g., greater than 50:50). If the premix includes, for example, a nonionic surfactant as an emulsifier, the heating step may not be required. If the premix includes, for example, a nonionic surfactant as an emulsifier, the heating step may not be required.

[0142] Test Method It will be understood that the test methods disclosed in the Test Methods section of this application should be used to determine the values of each of the parameters of the inventive subject matter claimed and described herein.

[0143] Test method for determining the logarithm of the octanol / water partition coefficient (logP) The logarithm of the octanol / water partition coefficient (logP) is calculated for each PRM in the fragrance mixture being tested. The logP values of individual PRMs are calculated using the Consensus logP Computational Model, version 14.02 (Linux®), available from Advanced Chemistry Development Inc. (ACD / Lab) (Toronto, Canada), which yields unitless logP values. The ACD / Labs Consensus logP Computational Model is part of the ACD / Labs model suite.

[0144] Softening Point Test Method Where available, the softening point of the vegetable rosin material provided by the manufacturer / supplier shall be used.

[0145] If not available from the manufacturer / supplier, the softening point is measured in accordance with ASTM E28-18 "Standard Test Methods for Softening Point of Resins Derived from Pine Chemicals," using the edition approved July 1, 2018, and published July 2018. More specifically, the reference method provided in the aforementioned edition ("Automated Ring and Ball Softening Point Method") must be followed. The method is summarized here.

[0146] As used herein (and as described in ASTM E28-18), softening point is defined as the temperature at which a disk of sample held in a horizontal ring (brass shoulder ring; 19.8 mm inner ring diameter, 23.0 mm outer diameter as directed in the ASTM method) is pressed downward a distance of 25.4 mm (1 inch) under the weight of a steel ball (9.53 mm diameter; mass 3.45-3.55 g) as the sample is heated at 5°C / min in a water, glycerin, silicone oil, ethylene glycol / water, or glycerin / water bath.

[0147] Sample preparation: Select a representative sample of the rosin material to be tested. The sample should contain freshly broken chunks without flakes or pastilles, or oxidized surfaces, and avoid the inclusion of finely divided material or dust. Melt the sample in a clean container, avoiding overheating and the introduction of air bubbles into the sample. The time from the start of heating to pouring the sample should not exceed 15 minutes. Place the ring, bottom down, on the metal surface. The ring may be preheated. Pour the molten rosin sample into the ring, ensuring that any excess remains upon cooling. After cooling for at least 30 minutes, remove excess material from around and on top of the ring.

[0148] Bath Fluid: The choice of bath fluid depends on the softening point ("SP") of the rosin material. For SPs between 35°C and 80°C, use water (distilled or deionized, freshly boiled). For SPs between 80°C and 150°C, use USP glycerin. For SPs above 80°C, use silicone oil (Polydimethylsiloxane-200 fluid, 50 cSt, Dow Corning, Midland, MI). For SPs up to 35°C, use a 50 / 50 (v / v) mixture of ethylene glycol and distilled water. The bath must be cooled to -25°C in a pre-cooled freezer or isopropyl dry ice bath.

[0149] Test: Use a suitable automated ring and ball softening point instrument equipped with a control unit and calibrate it according to the manufacturer's instructions. Place the stir bar in a 600 mL beaker and fill it with the bath solution listed above according to the softening point of the rosin material. Set up the apparatus, ring, ball, test insert, and support pin as recommended in the manufacturer's instructions. Ensure the control unit is set for the correct bath solution.

[0150] The bath is heated so that the temperature of the bath solution rises uniformly at a rate of 5°C / min. The test is complete when the beam is interrupted by the falling ball and the material. After the test is complete, the softening point is recorded as the temperature displayed on the unit.

[0151] Acid Number Test Method Where available, the acid number of the vegetable rosin material provided by the manufacturer / supplier should be used.

[0152] If not available from the manufacturer / supplier, the acid number is measured in accordance with ASTM D465-15 (re-approved in 2020) "Standard Test Methods for Acid Number of Pine Chemical Products Including Tall Oil and Other Related Products," approved June 1, 2020, and published June 2020. More specifically, the reference method provided in the above-mentioned publication ("potentiometric titration method") must be followed. The method is summarized here.

[0153] A sample of freshly chopped rosin material is prepared and may be further ground to facilitate weighing and dissolution; however, small pieces containing oxidized surfaces and existing rosin dust or powder should not be used. In the case of a heterogeneous liquid, place it in a sealed container with a minimal air vent or equivalent and heat it in a hot water bath. The sample may be stirred during heating, or may be used after thorough stirring to homogenize it.

[0154] Transfer the specified amount of sample to a 400 mL tall beaker based on the table below. Add the appropriate amount of Solvent I and swirl to dissolve, gently heating if necessary. Add the appropriate amount of Solvent II and cool to near room temperature if necessary. Immerse each electrode of a glass electrode pH meter (calibrated / standardized according to the manufacturer's instructions) into the solution. Stir with a stir bar.

[0155] Titrate with a standard aqueous alkali solution (0.5N or 0.1N KOH solution) and record the buret and pH meter readings. Sufficient alkali may be added to bring the solution to a pH of approximately 8. Add alkali in 1.0 mL increments until the pH changes by approximately 0.3 pH units per increment added. Reduce alkali addition to 0.1 mL or less until the endpoint is passed, as indicated by a significant decrease in pH units per 0.1 mL added. Continue titrating in 1.0 mL increments until a well-defined inflection point is apparent.

[0156] Determine the inflection point (the point of greatest change in pH per mL of alkaline solution) to the nearest 0.05 mL by plotting the pH reading against the milliliters of alkali used. (For greater accuracy, you can plot the pH probability per mL against the pH, with the peak corresponding to the inflection point.) The inflection point is considered to be the endpoint of the titration.

[0157] The acid number of the sample, expressed as milligrams of KOH per gram of sample, is: Acid value=(A×N×56.1) / B Where A = mL of alkali solution required for sample titration; N = normality of alkali solution; and B = sample weight (grams), the calculation may be reported to the nearest whole number.

[0158] Color Grade Test Method (Gardner Color) Where available, the vegetable rosin color grade (Gardner Color) provided by the manufacturer / supplier shall be used.

[0159] If not available from the manufacturer / supplier, color grade (Gardner Color) is measured in accordance with ASTM D6166-12 (reapproved in 2016) "Standard Test Method for Color of Pine Chemicals and Related Products (Instrumental Determination of Gardner Color)," approved December 1, 2016, and published December 2016. The method is summarized here.

[0160] Measure the color of the liquid sample using an instrument such as a Gardner Color Comparator L, 115V (e.g., BYK) that measures transmitted color and is capable of reporting in Gardner Color (or, less preferably, in a color system that can be converted to Gardner Color by known methods, such as that disclosed in ASTM D6166-12). Calibrate the instrument according to the manufacturer's instructions.

[0161] To prepare a rosin sample for color analysis, a molten sample of the rosin material is introduced into a glass cuvette (10 mm path, unless a different path is specified by the instrument manufacturer). If the sample is solid, it should contain freshly broken up chunks but should not contain dust or finely divided material. The solid should be melted (e.g., for less than 15 minutes in an oven, sand bath, or oil bath), taking care to avoid overheating and the introduction of air bubbles. After the molten sample is introduced into the glass cuvette, measurements should be made while it is still molten. If the material appears turbid, it should be filtered.

[0162] The glass cuvette is inserted into the instrument and the color is measured according to the manufacturer's instructions.

[0163] Flash Point Test Method Where available, the flash point of the vegetable rosin provided by the manufacturer / supplier shall be used.

[0164] If not available from the manufacturer / supplier, flash point will be measured in accordance with ASTM D92-18, "Standard Test Methods for Flash and Fire Points by Cleveland Open Cup Tester," approved July 1, 2018, and published July 2018.

[0165] Test Method for Determining the Amount of Major Rosin Acid Isomers When available, the amount of the major rosin acid isomer of the vegetable rosin provided by the manufacturer / supplier should be used.

[0166] If not available from the manufacturer / supplier, the amount of major rosin acid isomers is measured according to ASTM D5974-15, "Standard Test Method for Fatty and Rosin Acids in Tall Oil Fractionation Products by Capillary Gas Chromatography," approved July 1, 2015, and published August 2015. The method is summarized here.

[0167] This method uses gas chromatography to measure the level of rosin acids present in, for example, a rosin sample. Prior to chromatographic separation, certain free acids must be converted to their more volatile, more stable methyl esters. For rosin acids, this conversion may be accomplished with tetramethylammonium hydroxide (TMAH).

[0168] To prepare the methyl ester, dissolve the rosin sample (if solid, freshly crush to avoid oxidation) in 0.5-3.0 mL of a 50:50 ether / methanol mixture (and 2-3 drops of toluene, if necessary) and add 2-3 drops of phenolphthalein indicator solution. Titrate the mixture with a 6% solution of TMAH to a pH of 7.9-8.1 or until the first persistent pink color appears. If overtitrated, the mixture may be back-titrated with 5% acetic acid in methanol (v / v). Injecting the solution into the heated injection port of a chromatograph thermally decomposes the tetramethylammonium salt to the methyl ester.

[0169] A gas chromatograph (GC) equipped with a flame ionization detector (FID) was operated under the following conditions: column (oven) temperature: initial 150 °C; hold 5 min; ramp 5 °C / min; final 250 °C; hold 10 min; injection port temperature 300 °C; injection port liner, glass split; detector temperature 325 °C; carrier gas: helium; gas linear velocity: 19.5-20.5 cm / s; split ratio: maximum 100:1; detector (FID); hydrogen: 30 mL / min; air: 400 mL / min; makeup gas: 30 mL / min. A high-resolution column with a length of 30 m, an inner diameter of 0.32 mm, and a film thickness of 0.20 µm was used.

[0170] Prepare calibration standards of myristic acid and high-purity standards of any rosin acids expected to be present, record the weights, and convert to methyl esters as described above. To prepare test samples, accurately weigh approximately 50 mg of sample and approximately 15 mg of myristic acid into suitable vials, record the weights, and convert to methyl esters as described above.

[0171] Calibrate the GC using calibration standards (inject 0.5-1.0 μL), record retention times, and calculate individual relative response factors. To analyze test samples, inject 0.5-1.0 μL (dilute the sample with additional solvent if necessary), obtain the peak areas of all desired peaks from the chromatogram, and calculate the absolute value of each peak of interest. The relative percentage of each rosin acid methyl ester present may be determined by dividing the peak area of the rosin acid methyl ester being measured by the sum of the peak areas of all rosin acid methyl esters.

[0172] Fabric treatment methods When treating fabrics with the compositions described in this disclosure in the following experiments, the following procedure is followed unless otherwise indicated. For each treatment, a washing machine (e.g., Miele) is loaded with a fabric load of approximately 3 kg. The fabric load includes approximately 1065 g of cotton knit fabric and approximately 1065 g of polyester-cotton fabric (50 / 50). Additionally, the fabric load includes 20 terry towel tracers, each weighing approximately 870 g. A single wash cycle is then performed at 95°C.

[0173] Prior to the test treatment, the load is preconditioned twice with 79 g of unscented IEC A-based detergent (ex WFK, Testgewebe GmbH), each time using a short cotton cycle at 95°C, followed by two additional 95°C washes without detergent.

[0174] For the test treatment, the load is washed using a short cotton cycle at 40°C, a spin speed of 1200 rpm with 79 g of IEC A type detergent, which is added to the appropriate dispenser at the start of the wash cycle. A 40 mL dose of the test fabric treatment composition is added to the appropriate dispenser.

[0175] Method for determining headspace concentrations above treated fabrics At least two specific touchpoints: - WFO (Wet Fabric Odor or WET): Analyze the damp fabric after the fabric treatment process is completed. - DFO (Dry Fabric Odor or DRY): Fabric tracers from the fabric treatment methods described above were analyzed by headspace analysis in which the fabric was line dried in a closed room for approximately 24 hours and then the dry fabric was analyzed.

[0176] The headspace above the terry cotton tracer is analyzed using SPME headspace GC / MS (gas chromatography mass spectrometry) technique. A 4 cm x 4 cm aliquot of the cotton tracer is transferred to a 25 mL headspace vial. The fabric sample is equilibrated at 65°C for 10 minutes. The headspace above the fabric is sampled by SPME (50 / 30 μm DVB / Carboxen / PDMS) for 5 minutes. The SPME fiber is then subjected to online thermal desorption into the GC. The analytes are analyzed by GC / MS in full scan mode. The HS response of the total perfume and the perfume headspace composition at the top of the test leg can be measured.

[0177] Viscosity method The viscosity of the liquid composition is measured using a Brookfield DV-E viscometer, with the spindle automatically rotating at a speed of 60 rpm until a stable value is obtained in centipoise (cP).

[0178] The viscosity of the premix containing the vegetable rosin, delivery agent and potential emulsifier is measured using a HAAKE MARS from Thermo Scientific using a 60 mm, 1 degree cone and a 52 micrometer gap size. -1 The shear viscosity of is 0.01 s at 21°C. -1 ~1200s -1 Viscosity may be expressed as centipoise (cP).

[0179] Particle size measurement Depending on the relative diameter of the particles, one of two methods is used: image analysis if the volume-weighted median particle diameter of the population is approximately 10 μm or greater, or microscopic analysis if the volume-weighted median particle diameter of the population is less than 10 μm. These methods are described in more detail below.

[0180] A. Image Analysis The volume-weighted median particle diameter was calculated from images acquired from samples flowing through flow cells of various sizes. The instrument (Occhio FC200S) was specifically designed for image analysis in liquid applications. The sample was pumped via a syringe pump through the flow cell at a very slow speed, and images were acquired at set time points as the sample passed through the flow cell. The speed matched the camera frame rate and depended on the behavior of the sample and the particles it contained. The flow cell sizes used were 250 μm and 500 μm, depending on the capsule size. Capsule detection was performed via grayscale thresholding. Callisto version 2013.13 software was used to read out the pixels and calculate size and shape parameters. The size descriptor used was the ISO area diameter.

[0181] The illumination was a red LED light source and was manually adjusted until adequate grayscale detection of the particles was achieved. The hardware magnification was 6x or 9x, depending on the particle size.

[0182] B. Microscopy The diameters of approximately 900 capsules obtained from randomly sampled aliquots were observed and measured under a microscope, and the volume-weighted median particle diameter of the particles was calculated from the values obtained. The microscope used was a Leica DM6000B. The magnification of the microscope was set to 200x. The output obtained after microscopic analysis was (1) a list of detected diameters and (2) a count for each detected diameter size.

[0183] Therefore, the volume (V) of each particle is calculated using the following formula:

[0184]

number

[0185] The examples provided below are intended to be illustrative and not limiting in nature.

[0186] Example 1. Exemplary Plant Rosin Materials Table 1 shows various commercially available vegetable rosin materials. Additional information is provided where available. For the treatment compositions described in this disclosure, rosin materials according to numbers 2, 4, 7, and 9 may be particularly preferred.

[0187] [Table 2] * Mfr. = Manufacturer as indicated below: A-Eastman B-DRT C-Luresa Resinas SL

[0188] Example 2. Refreshing effect Below, liquid fabric softener (LFE) base compositions according to Table 2A are provided.

[0189] [Table 3] 1 Diester quaternary ammonium compound (Ci-DEEDMAC = ditallowoyl ethoxy ester dimethyl ammonium chloride [MDEA-based, methyldiethanolamine-based quaternary ammonium salt, available from Evonik]). 2 FLOSOFT™ FS 222 (e.g., SNF Floerger®)

[0190] Prepare the following rosin / fragrance premixes as shown in the table below. Weight percentages are based on the weight of the premix composition.

[0191] [Table 4]

[0192] Various liquid fabric softener ("LFE") products are made using the premix of Table 2B ("fragrance + vegetable rosin"). For each leg, a similar product is made with added perfume only (no premix, no vegetable rosin material) and this is used as the reference product (no vegetable rosin material; "fragrance only").

[0193] The products were used to treat fabrics according to the method provided above, and the dry fabric odor (DFO) for each was measured. The results are provided in Table 2C. Additionally, Table 2C shows the "Delta DFO," which indicates the difference between the DFO scores of the product containing the premix of Table 2B and the product containing only perfume. Furthermore, the "DFO ratio" is the ratio of the two DFO scores for that leg.

[0194] [Table 5] 2 Dispersibility relates to the ease of dispersion of the rosin material in the final product formulation, with 10 = very difficult to disperse, 5 = average dispersibility and 1 = good dispersibility.

[0195] The relatively high delta DFO scores and DFO ratios indicate that the formulations containing the premix provide a freshening effect when compared to the fragrance-only formulations.

[0196] As confirmed by the results of Legs A, B, and C, the LFE formulations containing vegetable rosin materials all provided DFO freshness benefits (as indicated by delta DFO and DFO ratio) compared to the respective flavor-only formulations. However, it can be seen that vegetable rosin glycerol esters and pentaerythritol esters produced relatively higher DFO scores compared to vegetable rosin methyl esters. While pentaerythritol esters provided good DFO scores, such materials can be relatively difficult to process, as indicated by the dispersibility scores. Thus, formulators can select the vegetable rosin material that best balances the desired performance and processability parameters, with glycerol esters providing a favorable combination of performance and dispersibility.

[0197] Example 3. Acid number and softening point Various vegetable rosin materials are added to the liquid fabric softener base to create the final product. The formulations of the LFE compositions are reported in Table 3A:

[0198] [Table 6] 1 Diester quaternary ammonium compound (Ci-DEEDMAC = ditallowoyl ethoxy ester dimethyl ammonium chloride [MDEA-based, methyldiethanolamine-based quaternary ammonium salt, available from Evonik]).

[0199] Table 3B lists specific vegetable rosin materials, each of which has an acid number (measured in mg KOH / g) greater than 140. The dispersibility of the rosin materials in the LFE compositions was evaluated and is reported below.

[0200] As indicated by the relatively high dispersibility ratings, the vegetable rosin materials listed in Table 3B are relatively difficult to disperse in final product formulations. This appears to be true even when the softening points are relatively low (e.g., Leg 3). B -6 and 3 B -7).

[0201] [Table 7] 2 Dispersibility relates to the ease of dispersion of the rosin material in the final product formulation, with 10 = very difficult to disperse, 5 = average dispersibility and 1 = good dispersibility.

[0202] Even when vegetable rosin materials have a relatively high acid number, they can still be useful materials in treatment compositions. For example, materials such as Foralyn E (see leg 3 above) B When a vegetable rosin material (see, for example, JP-A-2004-70266) has a relatively high acid number and a relatively low softening point, this may still result in good freshness. It is believed that the reason for this in the case of Foralyn E is that the material is at least partially hydrogenated. Therefore, it is believed that selecting a vegetable rosin material that has a high acid number, a low softening point, and is at least partially hydrogenated can provide a useful treatment composition.

[0203] Table 3C provides a list of specific vegetable rosin materials, each of which has an acid number below 15 (measured in mg KOH / g).

[0204] [Table 8] 2 Dispersibility relates to the ease of dispersion of the rosin material in the final product formulation, with 10 = very difficult to disperse, 5 = average dispersibility and 1 = good dispersibility.

[0205] When the acid number is relatively low, the difference in dispersibility ratings can be explained by the difference in softening point. In summary, when the softening point of the vegetable rosin material is relatively low, dispersibility improves.

[0206] A confirmation of the statistical effect of softening point on dispersibility of rosin materials with acid numbers below 15 (mg KOH / g) is made in Figure 1, where dispersibility ratings are plotted against softening point. The correlation of softening point to dispersibility is statistically significant as confirmed by the R^2 (0.967) and p-value (<0.001). The correlation shows how a low softening point can be favorable for dispersibility of rosin materials in the final product when the acid number is relatively low.

[0207] Example 4. Number of ester groups Table 4 compares similar gum rosin esters. The materials are made into rosin / fragrance premixes (50:50 by weight) and the premixes are evaluated for viscosity. The premixes are then incorporated into the base liquid fabric softener base composition and evaluated for dispersibility. The results are shown in Table 4.

[0208] [Table 9] 2 Dispersibility relates to the ease of dispersing the premix rosin / fragrance in the final product formulation, with 10 = very difficult to disperse, 5 = average dispersibility and 1 = good dispersibility. 3 20℃, 11.71s -1 Viscosity at shear rate of

[0209] As shown in Table 4, an increase in the number of ester groups per mole of the vegetable rosin ester material correlates with an increase in the softening point of the rosin material. In parallel, an increase in the number of ester groups per mole correlates with an increase in the viscosity of the rosin when mixed with flavor. Furthermore, an increase in the number of ester groups per mole to 3-4 moles results in a decrease in dispersibility in the final product.

[0210] Example 5. Color Grading Table 5 lists vegetable rosin materials with different color grades. The color grade of the vegetable rosin material is determined according to the Gardner Color Scale described in the Test Methods section above.

[0211] [Table 10] 1 Color grades are rated according to the Gardner color scale described in the Test Methods section above, with 1 = light color and 18 = very dark color. * Mfr. = Manufacturer: A = Eastman; B = DRT; C = Luressa Resinas SL

[0212] Typically, a lower color rating is preferred to minimize the impact on the final color of the treatment composition. By way of example, attention is directed to Figure 1, which shows a color photograph of a liquid fabric softener (LFE) product containing the plant resinous materials provided in Table 5. The LFE product is formulated with, among other things, fragrance and 7% by weight of an esterquat fabric softener, and is stored at 25°C for two days. After the storage period, photographs of the resulting composition are taken to show the color changes that occur over time.

[0213] As can be seen in the table of Figure 1, vegetable rosin materials with relatively low color ratings tend to result in less discoloration of LFE products during storage. For example, compare the relative color of LFE products formulated with Resins 1-4 (light) with those formulated with Resins 8-11 (dark). Selecting vegetable rosin materials with such relatively low color ratings can be particularly important when formulating / manufacturing undyed, undyed, or lightly colored product compositions. Such selection may even be preferable when formulating or manufacturing dyed or colored products, since color changes can adversely affect the product's aesthetics. For example, when formulating a blue product, a yellowish rosin color is less desirable, but over time, this may cause the product to turn green.

Instead, unless otherwise indicated, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm" is intended to mean "about 40 mm."
