The composition of any preceding claim, wherein the at least one hydrophobically-modified pullulancompound is a siloxane-modified pullulan compound, preferably trimethylsiloxysilylcarbamoyl pullulan. 45 WBD (US) 4857-1748-0140v1 Atty. Dkt. L1170431860WO (0186.3) OA23217-WO-PCT 7. The composition of any preceding claim, wherein the at least one aqueous phase film former is at least one cyclic amide-containing polymer, preferably a copolymer of N-vinyl pyrrolidone, methacrylamide, and N-vinylimidazole, a polyvinylpyrrolidone, a vinylpyrollidone/vinyl acetate copolymer, or mixtures thereof. 8. The composition of any preceding claim, wherein the weight ratio of aqueous phase film former to hydrophobically-modified pullulan compound is from about 3:1 to about 1:3, preferably about 1:1. 9. The composition of any preceding claim, wherein water is present in an amount greater than 20% by weight with respect to the total weight of the composition, preferably between about 25% and 60% by weight with respect to the total weight of the composition. 10. A method of making up skin comprising applying the composition of any preceding claim to skin in an amount sufficient to make up the skin. 11. A water-in-oil emulsion composition comprising (a) water, (b) at least one volatile hydrocarbon oil, (c) at least one siloxane-modified pullulan compound; (d) at least one cyclic amide-containing polymer; (e) at least one thickening agent which is a clay; (f) at least one surface-treated pigment; and (g) at least one vitamin compound. 46 WBD (US) 4857-1748-0140v1

Description

Atty. Dkt. L1170431860WO (0186.3) OA23217-WO-PCT TITLE OF THE INVENTION EMULSION COMPOSITIONS CONTAINING HYDROPHOBICALLY-MODIFIED PULLULAN COMPOUND AND AQUEOUS PHASE FILM FORMER CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Patent Application No.18/345,499, filed June, 30, 2023. This application also claims priority to French Patent Application No.2311122, filed October 16, 2023. FIELD OF THE INVENTION [0002] The present invention relates to water-in-oil (w/o) emulsions (compositions) comprising at least one hydrophobically-modified pullulan compound and at least one aqueous phase film former, as well as to methods and kits comprising such emulsion compositions in container(s) or in application. The compositions have beneficial cosmetic properties including good or improved wear, water and/or sebum resistance, and/or transfer resistance properties, in particular sebum resistance. DISCUSSION OF THE BACKGROUND [0003] At the present time on the market for caring for and making up keratin materials, many products claim staying power throughout the day, withstanding external factors such as water, sebum, mechanical friction, etc. (waterproof mascara, food-proof lipsticks, long-lasting foundations). Long-lasting products for the lips, the eyelashes, the eyebrows 1 WBD (US) 4857-1748-0140v1 Atty. Dkt. L1170431860WO (0186.3) OA23217-WO-PCT or the face, which can be used at home, are mainly based on synthetic coating polymers in the presence of organic solvents. For making up the lips and compositions for making up the face, compositions comprising unmodified silicone resin as film forming agent are known, such as the compound having the INCI name: Trimethylsiloxysilicate or a compound having the INCI name: Polypropylsilsesquioxane, or alternatively a silicone acrylate copolymer such as the product having the INCI name: Acrylates/polytrimethylsiloxymethacrylate copolymer). Long-lasting makeup products for the eyelashes and/or the eyebrows (mascaras, eyeliners) use, for their part, typically use waxes or film-forming polymer particles in aqueous suspension of the latex type (i.e.: styrene/acrylate copolymers) as film formers. [0004] Besides these long-lasting products, the current trend is towards semi-permanent makeup. Specifically, in recent years, conventional makeup products have met with competition from the market of semi- permanent makeup in professional salons. It is encountered in the sector of makeup for the eyes (semi-permanent mascara, permanent eyelash makeup, eyelash extensions, etc.), for the eyebrows (semi-pigmentation known as micro-blading), for the complexion (freckles, beauty spots or the whole face, glowing or healthy-complexion effect) or for the lips (semi- permanent tattooing). This new trend is driving consumers towards seeking increasingly long staying power for greater practicality (avoiding having to apply and remove makeup daily, healthy complexion effect immediately on waking up, etc.). 2 WBD (US) 4857-1748-0140v1 Atty. Dkt. L1170431860WO (0186.3) OA23217-WO-PCT [0005] The aim of the present invention is to propose compositions which offer excellent staying power of the expected cosmetic effects, notably the color of the makeup on keratin materials (skin, lips, nails, hair, eyelashes, eyebrows) which may extend the duration of the cosmetic composition on keratin materials, as well as improve wear of the cosmetic composition on keratin materials and its resistance to external forces such as one or more of mechanical friction, water, sweat and perspiration, sebum, oil, etc. [0006] In addition, the aim of the present invention is to propose compositions which afford staying power of the expected cosmetic effects, notably the color of the makeup on keratin materials, combined with a good level of comfort in comparison with conventional systems, in particular based on unmodified silicone resin.
