Non-limiting examples of fillers include silica powder; talc; polyamide particles, in particular those sold under the name ORGASOL® powders by Atochem; polyethylene powders; acrylic copolymer-based microspheres, such as those based on ethylene glycol dimethacrylate / lauryl methacrylate copolymer sold by Dow Corning under the name POLYTRAP® Systems; expanded powders such as hollow microspheres, in particular microspheres sold under the name EXPANCEL® thermoplastic microspheres by Kemanord Plast or under the name MICROSPHERE® F 80 ED microcapsules by Matsumoto;Powders of natural organic materials such as crosslinked or non-crosslinked corn starch, wheat starch or rice starch, such as crosslinked starch powders with octenylsuccinate anhydride sold under the name DRY-FLO® starch by National Starch; silicone resin microspheres such as those sold under the name TOSPEARL® microspheres by Toshiba Silicone; clays (bentone, laponite, saponite, etc.); and mixtures thereof.

[0065] In one notable embodiment, the other fillers present in the composition include a swelling clay. By "swelling clay" is meant a clay material that is capable of swelling in water. Smectite clays are an example of a swelling clay. The crystal structure of the smectite group is an octahedral alumina sheet sandwiched between two tetrahedral silica sheets. In one notable embodiment, the swelling clay is bentonite. Bentonite is a rock formed from highly colloidal and plastic clays composed primarily of montmorillonite, a clay mineral of the smectite group, and is produced by the in-situ devitrification of volcanic ash. In addition to montmorillonite, bentonite may contain feldspar, cristobalite, and crystalline quartz. Bentonite has the ability to form thixotropic gels with water, an ability to absorb large amounts of water.Variations in interstitial water and exchangeable cations in the interlayer space affect the properties of bentonite and therefore the commercial uses of different types of bentonite.

[0066] A notable swelling clay suitable for use in the composition is BENTONE GEL® ISD V dispersion, commercially available from d'Elementis Specialties, East Windsor, New Jersey. BENTONE GEL® GTCC V dispersion is an organically modified hectorite (disterammonium) dispersion in isododecane with added propylene carbonate.

[0067] The fillers (for example, swelling clay) may be present in the compositions of the present invention in an amount ranging from about 1% to about 10% by weight, such as about 0.1%, 0.5%, 1% by weight, or about 2%, 3%, 5%, or 10%, relative to the total weight of the composition, including all intermediate ranges and sub-ranges. Propylene carbonate, if any, may be present in the compositions of the present invention in an amount ranging from about 0.25% to about 2% by weight, or, for example, in an amount such that the weight ratio between the swelling clay and the propylene carbonate is about 2:1 to about 5:1.

[0068] Although in some embodiments certain fillers such as hydrophobic silica aerogels may be included, in some other embodiments the compositions are substantially free of hydrophobic silica aerogels.

[0069] Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are generally synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction from a supercritical fluid, most commonly supercritical CO2. This type of drying prevents shrinkage of the pores and the material. The sol-gel process and the various drying processes are described in detail in Brinker, CJ, and Scherer, GW, Sol-Gel Science: New York: Academie Press, 1990. Silica aerogels, in general, were disclosed in US Patent No. 9,320,689, the entire contents of which are incorporated herein by reference.

[0070] Examples of hydrophobic silica aerogels that can be used in the invention include the aerogel sold under the name VM-2260 (INCI name: Silica silylate), by Dow Corning, whose particles have an average size of about 1000 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0071] Examples include aerogels sold by Cabot under the references Aerogel TLD 201, Aerogel OGD 201, Aerogel TLD 203, ENOVA® Aerogel MT 1100 silica aerogel, ENOVA® Aerogel MT 1200 silica aerogel.

[0072] Aerogel sold under the name VM-2270 (INCI name: Silica silylate), by the company Dow Corning, will be used in particular, the particles of which have an average size ranging from 5 to 15 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0073] Silica aerogel particles, if used, can be used in the inventive compositions from 0.1% to about 8% by weight, preferably about

[0082] 0.1%, 0.2%, or 0.5% to approximately 0.5%, 1%, 2%, or 5% by weight, all weights being based on the weight of the composition as a whole. The compositions of the present invention may include at least one cosmetically or dermatologically acceptable additive such as a thickener, plasticizer, antioxidant, essential oil, botanical extract, perfume, preservative, fragrance, pasty fat substance, neutralizing agent and polymer, and cosmetically active agents and / or dermatological active agents such as, for example, emollients, moisturizers, vitamins, essential fatty acids and drugs. According to the present invention, the additives are incorporated from about 0.01%, 0.5% or 1% to about 1%, 2% or 5% by weight. The compositions of the present invention are useful as compositions for skin makeup, in particular lip makeup. The compositions can be prepared by methods known to those skilled in the art, for example, by loading a container with one or more solvents or oil and adding various ingredients and mixing. The pigments can be pre-ground into a suspension or slurry before being added. The composition may be water-free. The composition may be substantially water-free. The composition may be surfactant-free. The composition may be substantially free of cleaning agents. In various aspects, a method can be proposed for coloring the lips. The method may include providing a cosmetic makeup composition as disclosed herein, and applying the cosmetic makeup composition to the lips. Example 1 Sample stability was determined using different ratios (RI) between the non-silicone polymer and the reaction product. Samples were created as shown in Table 1 below, with RI ratios of 5 (S1), 2 (S3), 1 (S4), 0.5 (S5), and 0.2 (S6). Stability was visually assessed after 24 hours and after 2 weeks. [Table 3] Table 1# - Formulations SI S3 S4 S5 S6 Material % by weight % by weight % by weight % by weight % by weight Acrylate / isobornyl acrylate copolymer 25 20 15 10 5 Reaction product 5 10 15 20 25 Isododecane 60 60 60 60 60 Caprylic / capric triglyceride 10 10 10 10 10

[0083] After 24 hours, some signs of separation could be seen in S4 and S5, and separation had already occurred in S6. After 2 weeks, separation was visible in S4, S5, and S6, although S4 was borderline. No separation was seen in S1 or S3. Thus, it will be understood that, preferably, the RI ratio is greater than 1, and more preferably from 2 to 5. Example 2

[0084] The following formulations, in Table 2 below, were created to provide similar necking characteristics. Comparative 1 (C1) includes only the dispersion (with a hydrocarbon oil and a non-crosslinked non-silicone polymer), the solvent, and the pigment. Comparative 2 (C2) includes the MYCELX® reaction product, the hydrocarbon oil of the dispersion, the solvent, and the pigment. Comparative 3 (C3) features the hydrocarbon oil of the dispersion, but instead of the non-crosslinked non-silicone polymer, includes the acrylate / dimethicone copolymer (the active material in Shin-Etsu's KP-550 fluid), the solvent, and the pigment. Comparative 4 (C4) adds the same reaction product as C2 to C3. Specimen 1 (El) adds the same reaction product as C2 to CL. El was chosen to have an RI ratio of 3, but similar results occur at other ratios.

[0094] Gloss. To measure gloss, films of each formulation were stretched onto a byko-chart Black Scrub Panel P121-10N (BYK) with 1-mil necking bars. The samples were left overnight or until the films were dry. Gloss was then measured using a three-angle BYK glossmeter. The results are shown in Table 3 below. [Table 5] Table 3# - Gloss Results Cl C2 C3 C4 El Angle Units of brightness Units of brightness Units of brightness Units of brightness Units of brightness Units of brightness 20° 21.7 56.5 55.8 63.6 30.1 60° 61.7 72.8 73.5 75.9 69.9 85° 62 71.2 74.1 73.1 66.4 As we have seen, the addition of the reaction product increases gloss. However, it is worth noting that when adding the reaction product to the non-crosslinked non-silicone / oil polymer dispersion (e.g., comparing Cl to El), the increase in gloss is substantial at 20°, 60°, and 85°, and statistically significant. When adding the reaction product to the silicone / oil polymer dispersion (e.g., comparing C3 and C4), an increase in gloss is only truly noticeable at 20°, with any change at 60° or 85° being statistically insignificant. Tackiness / Adhesion. To measure tackiness / adhesion, compositions were stretched on the byko-chart Black Scrub Panel P121-10N (BYK) with 1-mil necking bars. Tackiness was then measured by: securing the substrate, using a 1 / 2-inch spherical probe to apply a force of 200 grams for 10 seconds, lifting the spherical probe at 10 mm / second perpendicular to the substrate, and measuring the tackiness by extracting the maximum force when the spherical probe was detached from the surface. The average tackiness (in grams of force) over 5 measurements can be seen in Table 4. [Table 6] Table 4# - Tackiness / Adhesion Cl C2 C3 C4 El Pegosity 11.69 2.97 6.34 17.58 55.45 The disclosed oil / non-silicone dispersion alone (Cl) has moderate tackiness. The reaction product alone (C2) has very low tackiness. The combination of the disclosed oil / non-silicone dispersion and the reaction product (El) has an effect Synergistic on tackiness, indicating greater adhesion, which is much more significant than the combination of the silicone oil / polymer and the reaction product (for example, comparing C3 and C4). The transition from C3 to C4 represents an increase in tackiness by a factor of approximately 2.8. The increase from Cl to El is by a factor of 4.7. This is a surprising and unexpected benefit of this combination.

[0095] Solvent resistance. To measure solvent resistance, each formulation was applied to a byko-chart Black Scrub Panel P121-10N #5015 using a 1 mil necking bar. The films were left to dry overnight at 35°C and 60% RH. To evaluate the samples, 6 drops of fluids (two drops of olive oil, two drops of artificial saliva, and two drops of 2% acetic acid) were placed on different sections of the film and then allowed to stand for 10 minutes. The amount of material removed by the drops themselves was assessed. In addition, a cotton swab was used to gently wipe each drop 15 times. The amount of product wiped onto the cotton swab and how / if the product migrated on the byko-chart substrate were then observed. The ratings used a scale from 0 (no elimination) to 3 (substantial elimination).

[0096] [Table 7] Table 5# - Solvent resistance Cl C2 C3 C4 El Olive oil 1.5 2.5 1.5 1 1 Acetic acid 1 2 1.25 1 0.5 Artificial saliva 0.5 1.25 0.75 0.25 0.25

[0098] As we have seen, the addition of the reaction polymer improved solvent resistance compared to the control formulations without the reaction polymer. Compare, for example, Cl to El and C3 to C4.
