  • Solid powdery cosmetic composition
    Patent number: 10660827
    Abstract: The present invention relates to a cosmetic composition, comprising: an oil phase in an amount of 20% by weight or more, preferably from 28% to 45% by weight, relative to the total weight of the composition, said oil phase including preferably at least one non-volatile oil, a pulverulent phase in an amount of 40% by weight or more, preferably from 55% to 70% by weight, relative to the total weight of the composition, at least one hydrophobic film-forming polymer, the cosmetic composition is obtainable, and preferably obtained, by a process comprising the steps of: mixing said oil phase, said hydrophobic film-forming polymer(s), said pulverulent phase, and at least one additional solvent to prepare a slurry; and shaping said slurry in a container by compression and/or aspiration to prepare the cosmetic composition.
