Description

Title of the invention: COSMETIC COMPOSITION INCLUDING A SILOXANE-TREATED COLORANT technical field

[0001] This disclosure relates to the field of cosmetic compositions, and more particularly to cosmetic compositions including a colorant and having a reduced chromatic variation. CONTEXT

[0002] Cosmetic formulations containing a colorant, particularly colorants that include a dye, may be susceptible to color changes over time, especially in liquid compositions. The present inventors have observed that this is the case with cosmetic compositions having a continuous oil phase. This can be problematic, as consumers generally want products that will have a predictable color appearance on the keratinous substrates to which they are applied (e.g., skin, lips, nails, and the like). In some cases, for example, to preserve the flexibility of the formulation, it may also be desirable to achieve improved color stability without the use of certain organic UV-stabilizing compounds.The compositions disclosed here offer improvements over these color stability issues, potentially overcoming one or more of the aforementioned drawbacks. BRIEF SUMMARY

[0003] A cosmetic composition containing a continuous oil phase that includes one or more oily substances and a colorant dispersed in the oil phase is proposed. The colorant includes a substrate comprising at least one xanthene tincture, such as disodium 2',4',5',7'-tetrabromo-4,5,6,7-tetrachlorofluorescein. The colorant further includes a hydrophobic siloxane surface treatment. The composition is essentially free of piperidinol compounds. In addition, in some embodiments, the composition is substantially free of water.

[0004] In other embodiments, the composition may also be essentially free of benzotriazoles or even essentially free of all organic UV stabilizing compounds. In some embodiments, the substrate further includes at least one metal salt, such as an aluminum salt.

[0005] In some embodiments, the composition is essentially free of all organic UV stabilizing compounds.

[0006] In some embodiments, the cosmetic composition is liquid.

[0007] In some embodiments, the colorant is present in a concentration of about 0.01% to about 10% by weight.

[0008] In some embodiments, the siloxane surface treatment comprises an alkyl silane, a dimethicone, or combinations thereof.

[0010] In some embodiments, the composition includes an internal polyol phase within the continuous fatty phase.

[0011] In some embodiments, the composition further comprises a fatty acid ester of a polyol.

[0012] In some embodiments, the composition further comprises one or more film-forming polymers, such as those selected from an allylic polymer, a C10-C40 alkyl acrylate polymer, and combinations thereof.

[0013] In some embodiments, the composition is substantially free of C1-C4 monoalcohols and C1-C4 monoacetates. In some other embodiments, the composition includes at least about 35% by weight of fatty substances. In some other embodiments, the composition includes from about 1% to about 10% by weight of an emulsifying agent. In some other embodiments, the composition includes from about 1% to about 40% by weight of one or more polymers.

In some other embodiments, the composition includes a plurality or even all of the limitations specified above.

[0014] According to another aspect of the invention, a method for the cosmetic compositions described above includes supplying the cosmetic composition and applying the cosmetic composition to lips, skin, or nails, for example, to provide a cosmetically improved appearance. Application to the lips is particularly noteworthy. DETAILED DESCRIPTION

[0015] As used herein, articles such as "a" and "an" are understood to mean one or more of what is claimed or described.

[0016] As used herein, the expression "at least one" means one or more and thus includes individual components as well as mixtures / combinations.

[0017] All percentages, parts and ratios are based on the total weight of the compositions of the present invention, unless otherwise stated. Except in the implementation examples, or unless otherwise stated, all numbers expressing quantities of ingredients (e.g., concentrations, ratios, and the like) and / or reaction conditions shall be understood as being modified in certain embodiments by the term "approximately", meaning within 10% to 15% of the stated number (e.g., "approximately 10%" means from 8.5% to 11.5%, such as 9% to 11%, and "approximately 2%" means from 1.7% to 2.3%, such as 1.8% to 2.2%).

[0018] Similarly, for ratios, the modifier "approximately" means within 10% or 15% of the ratio. For example, approximately 4:1 means from 3.4:1 to 4.6:1, preferably from 3.6:1 to 4.4:1. As a person skilled in the art will readily understand, when the first ingredient in a ratio is less than the second, then a ratio can be expressed "in inverse form." For example, if a second ingredient, B, is present in an amount or at a concentration 2.5 times greater than that of ingredient A, this can be identified by an A:B ratio of 1:2.5. "Approximately 1:10" means from 1:8.5 to 1:11.5, preferably from 1:9 to 1:11. As a person skilled in the art will understand, the modifier "approximately" also encompasses the exact number or ratio specified. Unless otherwise stated, all concentrations indicated as percentages are concentrations by weight and, unless otherwise stated, refer to the entire composition.

[0019] As used here, the term "between" two numbers is meant to include the numbers at the boundaries. Thus, between 0 and 1 would include both 0 and 1.

[0020] Unless otherwise specified, numeric ranges include the bounds and are intended to include all combinations and subcombinations. In particular, approximately 5%, 10%, or 15% to approximately 20%, 50%, or 60% may refer to approximately 5% to approximately 20%, approximately 5% to approximately 50%, approximately 5% to approximately 60%, approximately 10% to approximately 20%, approximately 10% to approximately 50%, approximately 10% to approximately 60%, approximately 15% to approximately 20%, approximately 15% to approximately 50%, or approximately 15% to approximately 60%. Furthermore, as used here, a ratio range is intended to include each specific ratio within the subranges and a combination of subranges between the given ranges.

[0021] As used herein, the terms "include", "includes" and "including" are understood to be non-limiting.

[0022] As used herein, the expression "substantially free (of an ingredient)" means that the composition contains less than 1%, such as less than 0.5% of the identified ingredient, or less than 0.3% of the identified ingredient. The expression "essentially free (of an ingredient)" means that the composition contains less than 0.25%, such as less than 0.1% of the identified ingredient, preferably below that amount. detectable quantities of the identified ingredient, and most preferably no quantity of the identified ingredient.

[0023] The term "anhydrous", as used here, refers to a composition substantially free of water or essentially free of water.

[0024] The disclosed compositions offer surprisingly improved color stability, as they are less sensitive to color changes than prior art compositions. When used in certain embodiments, in a composition having an internal phase including a polyol such as a polyol-in-oil emulsion, the compositions can further provide a sensory sensation of low adhesion.

[0025] Thus, a cosmetic composition can be proposed. The composition may be a liquid (for example, taking the shape of its container). In some embodiments, the composition is an emulsion.

[0064] To form a colorant suitable for use in the present invention, any one of various pigments formed from a substrate such as those described herein and treated with a dye, such as those also described herein, can then be surface treated with a siloxane surface treatment.

[0065] The colorant further includes a siloxane surface treatment. By "siloxane surface treatment" is meant any surface treatment that forms siloxane (Si-O-Si) bonds in the colorant and imparts water-repellent properties, such as a treatment involving an organosilane or a silicone. Suitable examples include organosilanes such as alkyl silane. The alkyl silane may be a C1-C30 alkylsilane such as triethoxycaprylyl silane. The alkyl silane may be a perfluoroalkylsilane. Alkylsilanes may bind to metal salts (e.g., oxides) present in the substrate. Other examples of such suitable siloxane surface treatments include silicones such as dimethicones and the like.

[0066] The colorant with the siloxane surface treatment may be present in the composition at a concentration of approximately 0.01% to approximately 10% by weight. In some embodiments, the colorant is present at a concentration of approximately 0.01%, 0.05%, 0.1%, or 0.25% to approximately 0.25%, 0.5%, 1%, 2%, 5%, or 10% by weight in the composition. In some embodiments, the total amount of all colorants falls within one or more of the ranges listed above.

[0067] According to certain embodiments, when considering the composition as a whole, the siloxane surface treatment and the substrate may each be present in a respective weight concentration in which the concentration in weight of substrate is greater than the weight concentration of the siloxane surface treatment.

[0068] Additional colorants such as "pearlescent agents," which exhibit a color effect through optical interference, as well as other color pigments including, for example, iron oxides, may also be included in the composition. Antioxidants

[0069] The compositions of the present invention may include antioxidants to prevent or interrupt ongoing oxidation that may begin within the composition. Notable examples include sterically hindered phenolic antioxidants such as pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate available as TINOGARD TT and octadecyl di-t-butyl-4-hydroxyhydrocinnamate TINOGARD TS, both available from BASF.

[0070] The concentration of antioxidant in the composition can be, for example, from about 0.05%, 0.1% or 0.15% to about 0.15%, 0.2%, 0.25% or 0.5% by weight in the composition. UV stabilizers

[0071] The compositions of the present invention, in certain embodiments, may include one or more organic ultraviolet (UV) light stabilizers (also referred to herein as stabilizing compounds). Ultraviolet light stabilizers are defined as organic ultraviolet compounds capable of protecting the composition against the potentially harmful effects of UV radiation by absorption of ultraviolet rays or by extinction in the excited state. "Organic" is defined as compounds consisting substantially, mainly, or entirely of carbon, hydrogen, oxygen, and / or nitrogen atoms.

[0072] UV stabilizers may include organic UV filters commonly used in cosmetic sunscreens to provide personal protection to the skin. By way of non-limiting examples, these may include p-aminobenzoic acid derivatives, anthranilates, benzophenones, camphor derivatives, cinname derivatives, dibenzoyl methanes, [3,[3-diphenylacrylate] derivatives, salicylic derivatives, triazine derivatives, benzimidazole compounds, bis-benzoazolyl derivatives, bis-(hydroxyphenylben zotriazole) methylene compounds, and the like.

[0073] Other UV stabilizers include various compounds often used to protect polymeric or other substrates—such as hindered amine compounds and / or excited-state quenching compounds such as piperidine compounds.

[0187] Six compositions were prepared that included the pigment Red 28 with and without various surface treatments. This includes three example formulas (Ex. 1, Ex. 2, and Ex. 3) and three comparative formulas (Comp. 1, Comp. 2, and Comp. 3). See Table 1 below. The samples were prepared by first preparing premixes 10% pigments by weight were obtained by adding 10% by weight of pigment to pentaerythrityl tetraisosterate. Separately, mixtures of additional oils and polymers, fatty compounds, and other ingredients were blended at approximately 90 °C. After blending and cooling to room temperature, appropriate pigment premixes were then added to form the compositions as detailed in Table 1.

[0188] The following colorants were used and are shown in the tables below: Pigment 1: Red 28 Lake treated with aloe; Pigment 2: Red 28 Lake treated with isopropyl titanium tristearate and triethoxysilylethyl polydimethylsiloxyethyl dimethicone; Pigment 3: Red 28 Lake treated with isopropyl titanium triisostearate (and) bis-ppg-15 dimethicone / ipdi copolymer (and) peg-2 soyamine polymer with isophorone diisocyanate; Pigment 4: Red 28 Lake treated with triethoxycaprylyl silane; Pigment 5: Red 28 Lake treated with avocado oil; and Pigment 6: Untreated Red 28 Lake.

[0189] The color change, AE, was determined using the following color stability test.

[0190] An Atlas CPS weather resistance test apparatus (Ametek, Mount Prospect, IL) was used. Samples were placed in a representative commercial clear lip gloss package. Duplicate samples were created for each test parameter. One product (the control) was protected from sun exposure in a closed / dark box, and the other sample was used in the solar chamber to simulate UV and heat exposure with controlled intensity and duration (765 W / m² for 24 hours).

[0191] The color stability in the packaging before and after the sunlight test was evaluated using a 700 mm DigiEye cubic instrument (VeriVede Enderby, Leicester, UK). Photographs of the samples were taken in a controlled light box. The analysis of color change was performed with a calibrated camera / software. For each composition, the L*a*b* values ​​were read and used to determine the AE as an indication of color change. A lower delta E means there was less color change, while higher delta E values ​​indicate a greater level of color change. The control (sample not exposed to UV) was compared to the AE for the sample subjected to the sunlight test, which allowed the amount of discoloration for each composition resulting from the sunlight test to be determined.

[0192] The measured colour change, AEechantion, is also shown in Table 1.

[0195] The following colorants were used and are shown in the different tables: Pigment 1: Red 28 Lake treated with aloe; Pigment 2: Red 28 Lake treated with isopropyl titanium tristearate and triethoxysilylethyl polydimethylsiloxyethyl dimethicone; Pigment 3: Red 28 Lake treated with isopropyl titanium triisostearate (and) bis-ppg-15 dimethicone / ipdi copolymer (and) peg-2 soyamine polymer with isophorone diisocyanate; Pigment 4: Red 28 Lake treated with triethoxycaprylyl silane; Pigment 5: Red 28 Lake treated with avocado oil; and Pigment 6: untreated Red 28 Lake.

[0196] It can be seen that the exemplary formulas Ex. 1-3 treatment (having received siloxane treatment) and Comp. 1 (having received aloe treatment) are significantly better than the untreated pigment and compared to the pigment treated with avocado oil. Example II

[0201]

[0202] In addition, other compositions were prepared that included the Red 28 pigment with and without various surface treatments, and further incorporated various UV stabilizers. The UV stabilizers included tris(tetramethylhydroxypiperidonol) citrate (TINOGARD Q, also from BASF). These compositions are shown in Table 2 below. The components other than the colorants were otherwise as shown in Table 1. The identity of pigments 1 to 6 is also described above. Pigment 5 was not tested (N / T). The measured color change, AEsampant, is also shown in Table 2, along with the calculated percentage improvement (%) compared to the untreated pigment without UV stabilizers (“ns”). % improvement (compared to the absence of stabilizer) = (AEns - AEsamplinon ) / AEns For calculations, AEns depends on the surface treatment and the values ​​are given in Table 1, more precisely: 19.08 (pigment 1), 22.75 (pigment 2), 26.12 (pigment 3), 23.34 (pigment 4), 30.22 (pigment 5) or 33.66 (untreated).

[0203] It can be seen that for the siloxane surface treatments of Comp. 5-7 and Comp. 11-13, the color change worsened remarkably, often substantially, when the UV stabilizer tris(tetramethylhydroxypiperidonol) citrate was used. This contrasts with the untreated pigment, which benefited from this particular stabilizer. It also contrasts significantly with the aloe treatment, which benefited mainly from the addition of tris(tetramethylhydroxypiperidonol) citrate. Example III

[0204] In addition, other compositions were made which included the pigment Red 28 with and without various surface treatments, and further included both tris(tetramethylhydroxypiperidonol) citrate (TINOGARD Q, also from BASF) and benzotriazole dodecyl p-cresol (TINOGARD TL from BASF).

[0205] The compositions are shown in Table 3 below. The components other than the colorants were otherwise as shown in Table 1. The identity of pigments 1 to 6 is also described above.

[0206] The measured colour change, AEsampantion, is also shown in Table 3, as is the calculated percentage improvement (%) compared to the untreated pigment without UV stabilizers (“ns”).

[0207] % improvement (compared to no stabilizer) = (AEns - AEechnon) / AEns

[0208] For calculations, AEns depends on the surface treatment and the values ​​are given in Table 1, more precisely: 19.08 (pigment 1), 22.75 (pigment 2), 26.12 (pigment 3), 23.34 (pigment 4), 30.22 (pigment 5) or 33.66 (untreated).

[0211] It can again be seen that for the siloxane surface treatments of Comp. 17-19, the color change was considerably aggravated when using the combination of the UV stabilizer tris(tetramethylhydroxypiperidonol) citrate and the UV stabilizer benzotriazole dodecyl p-cresol. This contrasts with the aloe treatment pigment and the avocado oil treatment, in which the compositions have benefited substantially from this particular combination of UV stabilizers. Example IV

[0212] In addition, other compositions were made which included the pigment Red 28 with and without various surface treatments, and further included only benzotriazole dodecyl p-cresol (TINOGARD TL from BASF).

[0213] The compositions are shown in Table 4 below. The components other than the colorants were otherwise as shown in Table 1. The identity of pigments 1 to 6 is also described above.

[0214] The measured colour change, AEéChantiiion, is also shown in Table 4, as is the calculated percentage improvement (%) compared to the untreated pigment without UV stabilizers (“ns”).

[0215] % improvement (compared to no stabilizer) = (AEns - AEechnon) / AEns
