Description

TITLE OF THE INVENTION O/W-EMULSION COMPOSITIONS CONTAINING A HYDROPHOBICALLY-MODIFIED POLYSACCHARIDE COMPOUND AND AN AQUEOUS PHASE FILM FORMER CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Patent Application No. 18/345,554 filed June, 30, 2023. This application also claims priority to French Patent Application No. 2311124, filed October 16, 2023. FIELD OF THE INVENTION [0002] The present invention relates to oil-in-water (o/w) emulsions (compositions) comprising at least one hydrophobically-modified polysaccharide 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, for example, as primer or setter compositions for good or improved wear, water and/or sebum resistance, and/or transfer resistance properties of separately-applied compositions. 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 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.). [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] Possibly related patent references include: [0007] US 11,253,462 discloses low-wax compositions containing silicone polymers among other ingredients; [0008] US 2020/0022898 discloses film forming compositions comprising a first anionic or non-ionic non-crosslinking polyacrylate random copolymer and a second cationic non-crosslinking polyamide random copolymer; [0009] US 11,033,478 discloses a self-curling mascara composition containing at least about 7 percent by weight of a non-ionic water-soluble or water dispersible copolymer that includes a cyclic amide monomer, a cyclic amine monomer, and an acrylamide monomer; [0010] US 2003/0082221 discloses compositions containing pullulan; [0011] US 2016/0113860 discloses compositions containing silicone-modified pullulan and silicone oils which it thickens; [0012] JP-A H08-208989 is discussed in the previous application, and characterized as disclosing silicone-modified pullulan which thickens silicone oil components, but which has an inadequate thickening effect; [0013] CN 111801092 discloses compositions for impregnating a material, where the compositions contain PEG or polyethyer modified-silicones as well as dendrimer type silioxanes; [0014] FR 3,104,958 discloses compositions containing polyurethane dispersions among other ingredients; and [0015] FR 3,110,849 discloses compositions containing polyurethane and/or acrylic dispersions among other ingredients, with little or no fatty material. [0016] There remains a need for improved compositions s
