Description

[0001] This application is a divisional application of Chinese invention application No. 201880077551.4 (International Application No. PCT / US2018 / 053114), filed on September 27, 2018, entitled "Cosmetic Composition Capable of Forming a Multilayer Structure After Being Applied to Keratin Material". Invention Field

[0002] This invention relates to cosmetic compositions that can form a multilayer structure after being applied to a keratin material. Such compositions allow for the benefits associated with multilayer cosmetic products without having to participate in a multi-step application process. Background Technology

[0003] Many cosmetic compositions (including coloring cosmetics such as lipsticks, foundations, and eyeshadows) have been formulated in an attempt to provide long-lasting wearability after application. Unfortunately, many of these compositions typically do not simultaneously possess good long-lasting / transfer resistance properties as well as good application properties, good comfort properties, and / or good appearance properties (e.g., glossy or matte properties).

[0004] For example, in lip products, there are known products containing silicone resins (e.g., MQ resin). Such products are known to offer good long-lasting wear and / or resistance to transfer. However, these products have poor application properties, a poor feel upon application (e.g., a rough feel), and poor gloss or shine properties (e.g., a matte appearance) attributable to the film formed by the MQ resin. Therefore, a second composition (outer coating) is applied alone to such products to improve the poor properties of the composition and make the product acceptable to the consumer. Furthermore, the outer coating composition must be continuously reapplied so that the product remains acceptable to the consumer, meaning that the product is not actually "long-lasting" because it requires constant maintenance and reapplication.

[0005] Similarly, for foundation, such products offer good long-lasting wear and / or resistance to color transfer. However, these long-lasting / color-resistant products may have poor application properties and / or a poor feel upon application, as well as poor matte finish.

[0006] Therefore, there remains a need for improved “single-step” cosmetic compositions that possess improved cosmetic properties, particularly good staying power, feel, shine, gloss, and / or matte finish upon application, while also being stable formulations. Summary of the Invention

[0026] Components A and B are immiscible, and

[0027] The weight ratio of the silicone-containing film-forming agent and / or hydrocarbon-containing film-forming agent in component A to the silicone compound in component B is approximately 50:1 to 1:2.

[0028] Another aspect of the invention relates to a kit. In one or more embodiments, the kit comprises (a) any composition described herein; (b) at least one container containing the cosmetic composition according to claim 1; and (c) at least one applicator. In one or more embodiments, at least one container is configured to mix the cosmetic composition.

[0029] Another aspect of the invention relates to a method of applying a cosmetic composition described herein. In one or more embodiments, the cosmetic composition is mixed to form a mixed composition wherein component A and component B are temporarily miscible; and the mixed composition is applied to a keratin material.

[0030] It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory, and do not limit the invention. Detailed Implementation

[0031] As used herein, “at least one” means one or more kinds of one or more, and therefore includes individual components as well as mixtures / combinations.

[0032] Except as indicated in the operational examples or elsewhere, all figures representing the amount of an ingredient and / or reaction conditions should be understood to be modified in all cases by the term “about,” which means within 10% to 15% of the indicated figures.

[0033] As used herein, “film former” or “film forming agent” refers to a polymer or resin that leaves a film on a substrate to which it is applied.

[0034] As used in this article, “polymer” refers to a compound consisting of at least two monomers.

[0035] As used herein, “substituted” means containing at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen and nitrogen atoms; and functional groups, such as hydroxyl, ether, alkoxy, acyloxyalkyl, alkenyl, polyoxyalkyl, carboxylic acid, amino, acylamino, amide, halogen-containing groups, ester, mercapto, sulfonate, thiosulfate, siloxane, hydroxyalkyl, and polysiloxane. Substituents may be further substituted.

[0036] As used in this article, "volatile" means having a flash point below approximately 100°C.

[0037] As used in this article, "non-volatile" means having a flash point above approximately 100°C.

[0038] "Anhydrous" means that the composition contains less than 1% water. Preferably, the composition of the present invention contains less than 0.5% water, and most preferably is anhydrous.

[0039] As used herein, “transfer resistance” refers to the quality exhibited by a composition that is not easily removed by contact with another material such as glass, clothing, or skin, for example, when ingested or consumed. Transfer resistance can be assessed by any method known in the art for evaluating such qualities. For example, the transfer resistance of a composition can be assessed by a “touch” test. A “touch” test may involve applying the composition to a keratin material such as hair, skin, or lips, and then rubbing a material (e.g., a sheet of paper) against the hair, skin, or lips after a certain period of time (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 minutes after application). Similarly, the transfer resistance of a composition can be assessed by the amount of product transferred from the wearer to any other substrate (e.g., after a certain period of time following application to hair, skin, or lips, when wearing clothing). The amount of composition transferred to a substrate (e.g., collar or paper) can then be evaluated and compared. For example, if most of the product remains on the wearer's hair, skin, or lips, the composition is considered transfer-resistant. Furthermore, the amount transferred can be compared to the amount transferred by other compositions, such as commercially available compositions. In a preferred embodiment of the invention, little or no composition transfers from the hair, skin, or lips to the substrate.

[0040] As used herein, “adhesion” refers to the quality exhibited by the composition in adhering to a substrate after application. Adhesion can be assessed by any method known in the art for evaluating such quality. For example, a sample to be tested for adhesion properties can be deposited onto a surface such as a biological skin substrate or Byko-Charts Black Scrub Panels P122-10N (6.50 x 17.00 inches). After drying, a sheet of ASTM cross-cut adhesive tape (Permacel 99 / PA-28060 / 51596) can be placed on the sample and removed at a 180° angle. How much sample adheres to the tape can then be determined. For example, a rating scale (e.g., a scale of 1–3) can be used to evaluate the extent to which the sample is removed from the substrate to the tape, where 1 is substantially not removed, 2 is partially removed, and 3 is substantially completely removed.

[0041] As used herein, the term "rub resistance" refers to physical abrasion, such as rubbing human skin with hands or clothing, or other physical interactions. It can also be described as the ability to retain active ingredients on the skin or to prevent the active ingredients from being removed from the skin or a substrate such as Byko-Charts Black Scrub Panels P122-10N (6.50 x 17.00 inches) or biological skin through abrasion or other physical interactions.

[0042] As used herein, a “long-lasting” composition refers to a composition in which, after an extended period of time, the color remains the same or substantially the same as at the time of application, as observed by the naked eye. Long-lasting properties can be assessed by any method known in the art for evaluating such properties. For example, long-lasting properties can be assessed by a test involving applying the composition to the skin and evaluating the color of the composition after an extended period of time. For example, the color of the composition can be assessed immediately after application to the skin, and these properties can then be reassessed and compared after a certain amount of time. Furthermore, these properties can be assessed relative to other compositions, such as commercially available compositions. Alternatively or additionally, long-lasting properties can be assessed by applying a sample, allowing it to dry, and then rubbing the sample to determine the removal / loss of the sample.

[0043] The cosmetic compositions and methods of the present invention may comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise used for personal care.

[0044] Compositions capable of forming multilayer structures

[0045] According to various embodiments of the invention, cosmetic compositions are provided that can form a multilayer structure upon application to a keratin material. Such compositions allow for the benefits associated with multilayer cosmetic products without requiring a multi-step application process. In one or more embodiments, such compositions are suitable as lipsticks, lip glosses, foundations, eyeshadows, and other skin compositions.

[0046] According to one or more embodiments of the present invention, the cosmetic composition of the present invention comprises at least two components, hereinafter referred to as "component A" and "component B". In one or more embodiments, both component A and component B comprise silicone. Component A may, for example, comprise a silicone-containing film-forming agent. Component B may, for example, comprise silicone gum. In some embodiments, component A comprises a hydrocarbon film-forming agent, and component B comprises a silicone compound. Again, component B may, for example, comprise silicone gum. In one or more embodiments, component A may comprise both a silicone-containing film-forming agent and a hydrocarbon-containing film-forming agent.

[0047] Component A is the component of the composition that forms the layer closest to the keratin material in a multilayer structure after the composition of the present invention is applied to the keratin material. This layer in the multilayer structure is referred to below as "layer A". According to a preferred embodiment, component A / layer A has an affinity for the surface of the keratin material due to its surface energy properties with the keratin material.

[0048] Component B is the component of the composition that forms the layer furthest from the keratin material in a multilayer structure after the composition of the present invention is applied to the keratin material. This layer in the multilayer structure is referred to below as "layer B". According to a preferred embodiment, component B / layer B has an affinity for the air interface.

[0049] According to the present invention, all amounts and ratios by weight described herein with respect to component A and component B refer to the amount of active material (i.e., non-volatile material) in these components. Similarly, all amounts and ratios by weight described herein with respect to layer A and layer B refer to the amount of active material present as layer A and layer B after the volatile solvent has evaporated.

[0050] Before being applied to the keratin material, components A and B are immiscible in the composition of the present invention. Preferably, the immiscibility of the immiscible components results from the incompatibility between the two components when the composition is at rest and / or from the incompatibility between the two components after being applied to the keratin material.

[0051] In one or more embodiments, the immiscibility of the immiscible components is caused by differences in, for example, the viscosity, glass transition temperature, interfacial tension, solubility parameters, density, and / or chemical / structural incompatibility of the components; and / or differences caused by temperature and / or pressure.

[0052] For example, the immiscibility of components that are immiscible when the composition is at rest can be caused by: chemical / structural incompatibility, differences in interfacial tension between components (e.g., differences in interfacial tension between phases in mutually compatible solvents), differences in viscosity, differences in the glass transition temperature of polymers within each phase, and / or differences caused by temperature and / or pressure.

[0053] For example, the immiscibility of components that are immiscible when applied to a composition can be caused by factors such as chemical / structural incompatibility, differences in interfacial tension between components, differences in component density after solvent evaporation, and / or differences caused by temperature and / or pressure.

[0054] In one or more embodiments, the compositions of the invention are mixed or blended immediately before and / or during application to the keratin material, such that components A and B are temporarily miscible when the compositions of the invention are applied to the keratin material.

[0055] After the composition of the present invention has been applied to a keratin material, component A and component B separate. As the composition dries on the coated keratin material, the immiscible components A and B form a multilayer structure on the keratin material, each comprising layer A and layer B, for example:

[0056] Layer B Layer A Keratin materials

[0057] According to one or more embodiments of the invention, after the composition of the invention has been applied to a keratin material, component B produces a horizontal layer B: that is, layer B is planar, so that it can have refractive properties to impart gloss to the composition. According to these embodiments, component B has self-leveling properties: this produces a horizontal layer B after application. If desired, the gloss of such compositions can be enhanced by adding one or more gloss or shine enhancers with high refractive index properties. Alternatively, such compositions can be given matte properties by adding one or more matting agents.

[0058] According to a preferred embodiment of the invention, after the composition of the invention has been applied to a keratin material, component B produces a non-horizontal layer B: that is, layer B is not planar, thus imparting a matte finish to the composition. According to these embodiments, component B does not have self-leveling properties: this results in a non-horizontal layer B after application. If desired, the matte finish of such compositions can be enhanced by adding one or more matting agents. Alternatively, gloss or shine-enhancing agents with high refractive index properties can be added to provide gloss / brightness properties to such compositions. Another benefit of the composition is that, when used as a base / base coat, its self-leveling properties provide a smooth surface, thereby reducing blemishes on the skin.

[0059] According to the invention, the multilayer structure comprises layer A and layer B. In some cases, depending on factors such as component ratios, component concentrations, solvent evaporation characteristics, and the Tg of the polymer, the layers may slightly mix with each other after being coated with a keratin material, resulting in layer A having a larger amount of A and a smaller amount of B and / or layer B having a larger amount of B and a smaller amount of A. Preferably, layer A comprises 40% or less of layer B, more preferably 30% or less of layer B, more preferably 20% or less of layer B, more preferably 10% or less of layer B, and more preferably 5% or less of layer B, including all ranges and subranges therein. Similarly, preferably, layer B comprises 40% or less of layer A, more preferably 30% or less of layer A, more preferably 20% or less of layer A, more preferably 10% or less of layer B, and more preferably 5% or less of layer A, including all ranges and subranges therein.

[0060] Factors affecting the separation of component A and component B after coating a keratin material may include, for example, those properties discussed above, including but not limited to, the surface energy of the substrate, the density of each component, the evaporation properties of the solvent, the Tg of the film-forming material, and / or the viscosity of the film-forming material.

[0061] While not wishing to be bound by any particular theory, it is believed that the surface energy properties of component A are closer to those of the keratin material to which it is coated than those of component B. For example, the surface energy of skin is estimated to be 36 mN / m. Therefore, given that component A has a surface energy of approximately 36 mN / m, it is believed that component A can migrate to the skin. Component B would preferably have a lower surface energy, making it more likely to migrate toward the air interface.

[0062] While not wishing to be bound by any particular theory, it is believed that the interfacial tension between component A and component B affects phase separation (especially the rate of separation of component A and component B after coating). Such phase separation is believed to be influenced by differences such as those discussed above, including, for example, differences in temperature between component A and component B, differences in the Tg of component A and component B (the higher the Tg of a component, the longer the phase separation will take), differences in the weight fraction of the film-forming material, and / or differences in pressure between component A and component B.

[0063] These differences will be discussed further below.

[0064] Glass transition temperature (Tg)

[0065] According to a preferred embodiment, component A and / or component B comprise at least one silicone-containing film-forming agent and / or a hydrocarbon-containing film-forming agent, having at least one glass transition temperature below 60°C, preferably below 55°C, preferably below 50°C, and preferably below normal human body temperature (98.6°F or 37°C). Preferably, component A and / or component B comprise at least one silicone-containing film-forming agent and / or a hydrocarbon-containing film-forming agent, all of which have glass transition temperatures below human body temperature (98.6°F or 37°C). As is known in the art, plasticizers may be added to adjust the Tg of the film-forming agent. According to a preferred embodiment, both layer A and layer B comprise at least one film-forming agent having a glass transition temperature below 37°C.

[0066] The preferred method for determining Tg is to remove all volatile solvents from the layer and determine Tg by differential scanning calorimetry.

[0067] density

[0068] According to a preferred embodiment, component A and component B have different density properties, and this difference makes component A and component B immiscible in the composition of the present invention. Preferably, component A / layer A and component B / layer B have a density of 0.001-1 kg / m³. 3 Preferred concentration: 0.005-0.8 kg / m 3 And preferably 0.01-0.6 kg / m 3 The density difference.

[0069] temperature

[0070] According to a preferred embodiment, components A and B are affected by temperature, and this effect causes components A and B to remain immiscible in the composition of the present invention at temperatures below 50°C for a predetermined period of time, as is known in the art, unlike emulsions that are considered stable under such conditions.

[0071] weight fraction

[0072] According to a preferred embodiment, component A and / or component B comprises at least one polymer, such as a film-forming agent having a critical entanglement molecular weight (Mc), such that:

[0073] If present in component A, the at least one polymer has Mc < wMw, where w = weight fraction and Mw = molecular weight of the polymer; and

[0074] If present in component B, the at least one polymer has Mc ≤ wMw ≤ 108 g / mol.

[0075] Furthermore, according to a preferred embodiment, the viscosity of at least one polymer in component B is greater than 350 cSt, preferably greater than 500 cSt, preferably greater than 750 cSt, and preferably greater than 1000 cSt, including all ranges and sub-ranges therebetween.

[0076] Element

[0077] Component A and component B can be different in various ways mainly based on the different functionalities associated with layer A and layer B. For example, in the case where layer A performs a transfer resistance or adhesion function, the composition of component A can be selected to achieve transfer resistance or adhesion. Similarly, in the case where layer A performs a color enhancement function, at least one colorant can be added to component A. And, for example, in the case where layer B performs a gloss enhancement function and / or provides a better feel (e.g., provides a more comfortable feel) and / or provides a barrier layer to inhibit color transfer, the composition of component B can be selected to achieve gloss, brightness, comfort, and / or barrier layer properties. However, it should be understood that at the interface between layer A and layer B, the interface of layer A can have properties more related to layer B (e.g., gloss), while layer B can have properties more related to layer A (e.g., adhesion).

[0078] According to a preferred embodiment, component A comprises at least one silicone-containing film-forming agent and / or a hydrocarbon-containing film-forming agent and / or at least one colorant, and layer A provides adhesion, transfer resistance, and / or color properties to the multilayer structure. According to such an embodiment, component B can comprise at least one gloss enhancer, at least one comfort agent, and / or at least one barrier agent, and layer B provides gloss, comfort, and / or barrier properties to the multilayer structure.

[0079] In some embodiments, the composition comprises less than about 1% or 0.5% of a fluorinated compound, or does not contain a fluorinated compound.

[0080] According to a preferred embodiment, the composition of the present invention contains less than 0.5% of a fluorinated compound.

[0081] According to a preferred embodiment, the composition of the present invention is free of fluorinated compounds.

[0082] According to a preferred embodiment, at least one identical solvent is used in components A and B. Preferably, the main components of all solvents present in each component are the same.

[0083] According to the preferred embodiment, the weight ratio of component A to component B is 1:50 to 1.5:1, 1:75 to 1.5:1, 1:50 to 1.5:1, or 1:20 to 1.5:1, including all ranges and subranges therein.

[0084] Examples of acceptable ingredients added to component A and / or component B are discussed below.

Silicone-containing film-forming agents and hydrocarbon-containing film-forming agents are known in the art, and any silicone-containing film-forming agent and / or hydrocarbon-containing film-forming agent may be used.

[0107] Contains silicone film-forming agents (film-forming materials)

[0108] The compositions of the present invention may comprise at least one silicone-containing film-forming agent. As used herein, "silicone-containing film-forming agent" refers to a film-forming agent containing silicone. In one or more embodiments, "silicone-containing film-forming agent" comprises polymers containing at least about 2.5%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 99% silicone by weight. Silicone-containing film-forming agents are known in the art, and any silicone-containing film-forming agent may be used. According to a preferred embodiment, the compositions of the present invention comprise at least one silicone-containing film-forming agent having at least one glass transition temperature below 60°C, preferably below 55°C, preferably below 50°C, and preferably below normal human body temperature (98.6°F).

[0110] In one or more embodiments, the silicone-containing film-forming agent is selected from silicone resins, silicone acrylate copolymers, and mixtures thereof.

[0111] silicone resin

[0112] As used herein, the term "resin" refers to a cross-linked or non-cross-linked three-dimensional structure. According to one or more embodiments of the invention, component A comprises at least one silicone acrylate. The nomenclature for silicone resins is known in the art as the "MDTQ" nomenclature, thereby describing silicone resins based on the various monomeric siloxane units constituting the polymer.

[0113] Each letter in “MDTQ” represents a different type of unit. The letter M represents a monofunctional unit (CH3)3SiO1 / 2. This unit is considered monofunctional because when this unit is part of a polymer, the silicon atom shares only one oxygen atom. The “M” unit can be represented by the following structure:

[0114]

[0115] At least one of the methyl groups in the M unit may be replaced by another group to, for example, produce a unit having the formula [R(CH3)2]SiO1 / 2, as represented in the following structure:

[0116]

[0117] R is selected from groups other than methyl. Non-limiting examples of such groups other than methyl include alkyl, alkenyl, alkynyl, hydroxyl, mercapto, ester, acid, and ether groups other than methyl, wherein the groups other than methyl may be further substituted.

[0118] The symbol D represents the bifunctional unit (CH3)2SiO2 / 2, in which the two oxygen atoms bonded to the silicon atom are used to bind to the remainder of the polymer. The "D" unit is the main building block of polydimethylsiloxane oil, and can be represented as:

[0119]

[0120] At least one of the methyl groups in the D unit can be replaced by another group to produce, for example, a unit having the formula [R(CH3)2]SiO1 / 2.

[0121] The symbol T represents the trifunctional unit (CH3)SiO3 / 2, and can be represented as:

[0122]

[0123] At least one of the methyl groups in the T unit can be replaced by another group to produce, for example, a unit having the formula [R(CH3)2]SiO1 / 2.

[0124] Finally, the letter Q represents the tetrafunctional unit SiO4 / 2, in which silicon atoms are bonded to four hydrogen atoms, which themselves are bonded to the remainder of the polymer.

[0125] Therefore, a large number of different silicone polymers can be manufactured. Furthermore, it will be apparent to those skilled in the art that the properties of each potential silicone polymer will vary depending on the type of monomer, the type of substituent, the size of the polymer chain, the degree of crosslinking, and the size of any side chains.

[0126] Non-limiting examples of silicone polymers include silyloxysilicates and silsesquioxanes.

[0127] A non-limiting example of a silyloxysilicate is trimethylsilyloxysilicate, which can be represented by the following formula:

[0128] [(CH3)3XSiXO]xX(SiO4 / 2)y

[0129] (i.e., MQ unit), where x and y can be, for example, 50 to 80. On the other hand, silsesquioxanes can be represented by the following formula:

[0130] (CH3SiO3 / 2).x

[0131] (i.e., T units), where x can, for example, have values ​​of up to several thousand.

[0132] Resin MQ, available from Wacker, General Electric, and Dow Corning, is an acceptable example of a commercially available silaneoxysilicate. For example, trimethylsilaneoxysilicate (TMS) is commercially available from General Electric under the trade name SR1000 and from Wacker under the trade name TMS 803. TMS is also commercially available from Dow Chemical in solvents such as cyclodimethylsiloxanes. However, according to the invention, TMS can be used as 100% active material, i.e., not in a solvent.

[0133] Suitable silicone resins comprising at least one T unit according to the invention are disclosed, for example, in U.S. Patent Application Publications Nos. 2007 / 0166271, 2011 / 0038820, 2011 / 0002869 and 2009 / 0214458, the entire contents of which are incorporated herein by reference.

[0134] When a silicone resin contains at least one T unit, it can therefore be, for example, a T resin, an MT resin, an MTQ resin, or an MDTQ resin.

[0135] According to a preferred embodiment, the unit composition of the silicone resin may be at least 50% T units, or at least 70% T units, or at least 80% T units, or at least 90% T units.

[0136] In the M, D, and T units listed above as examples, at least one of the methyl groups may be substituted. According to a preferred embodiment, at least one silicone resin comprising at least one trifunctional unit of formula (R)SiO3 / 2 is selected from silsesquioxanes of formula ((R')SiO3 / 2)x, wherein x is 100 to 500, and R' is selected independently from the trifunctional unit from a hydrocarbon-based group or a hydroxyl group containing 1 to 10 carbon atoms, provided that at least one R' is a hydrocarbon-based group. According to a preferred embodiment, the hydrocarbon-based group containing 1 to 10 carbon atoms is methyl. According to a preferred embodiment, at least one silicone resin comprising at least one trifunctional unit of formula (R)SiO3 / 2 is selected from silsesquioxanes of formula ((R')SiO3 / 2)x, wherein x is 100 to 500, and R' is selected independently from the unit from CH3, a hydrocarbon-based group or a hydroxyl group containing 2 to 10 carbon atoms, provided that at least one R' is a hydrocarbon-based group.

[0137] According to a preferred embodiment, the T resin may contain M units, D units, and Q units, such that at least 80 mol% or at least 90 mol% of the total amount of silicone is T units. The T resin may also contain hydroxyl and / or alkoxy groups. The T resin may have 2% to 10% of the total weight of hydroxyl functional groups and up to 20% of the total weight of alkoxy functional groups; in some embodiments, the total weight of hydroxyl functional groups is 4% to 8%, and the total weight of alkoxy functional groups is up to 10%.

[0138] The silicone resin may be selected from silsesquioxanes represented by the following formula: ((CH3)SiO3 / 2)x, where x may be up to several thousand, and the CH3 group may be replaced by an R group (as described above in the definition of the T unit). The number of T units x of the silsesquioxane may be less than or equal to 500, or it may be 50 to 500, including all ranges and subranges therebetween. The molecular weight of the silicone resin may be from about 500 g / mol, 1000 g / mol, 5,000 g / mol, 10,000 g / mol, 15,000 or 20,000 g / mol to about 30,000 g / mol, 35,000 g / mol, 40,000 g / mol, 45,000 g / mol, 50,000 g / mol, 75,000 g / mol or 100,000 g / mol, including all ranges and subranges therebetween.

[0264] Example

[0265] preparation

[0266] Several liquid lipstick formulations containing the ingredients shown in Table 3 below were prepared. The mixture of pigments and film-forming agents was treated to produce a pigment dispersion. This blend was treated using a Disconti Mill until the dispersion passed the Hegman Gauge test (ASTM D1210-05). Polydimethylsiloxane and polydimethylsiloxane were mixed under high shear until homogeneous. The pigment dispersion, silicone mixture, and remaining ingredients were then combined and stirred at 60°C until a homogeneous liquid composition was obtained. The samples were then cooled to room temperature and transferred to the desired container and / or applicator.
