COMPACT, TALC-FREE, SURFACE-TREATED POWDER BASED ON MICA, A NON-VOLATILE NON-PHENYLATED SILICONE OIL AND AN AMORPHIC HYDROCARBON SEQUENCE COPOLYMER

摘要

The present invention therefore relates to a solid composition, in particular for coating keratin materials, more particularly for making up and / or caring for keratin materials, such as the skin, in the form of a compact powder, in particular comprising a physiologically acceptable medium and containing at least : - an oily phase in an amount of at least 20% by weight relative to the total weight of the composition; said oily phase comprising at least one non-volatile non-phenylated silicone oil; and - a pulverulent phase in an amount of at least 40% by weight relative to the total weight of the composition; said pulverulent phase comprising at least particles of mica; and - at least one amorphous hydrocarbon block copolymer; said composition not containing any untreated talc particle at the surface and being obtainable by a process comprising the following steps: (i) mixing the oily phase, the amorphous hydrocarbon block copolymer, the pulverulent phase and the one or more volatile solvents to form a slurry; and (ii) the sludge is shaped in a container by compaction, in particular pressing and / or suction to obtain the composition in powder form. The invention also relates to a process for coating keratin materials, more particularly for making up and / or caring for keratin materials, such as the skin, characterized in that it comprises the application to the keratin materials of a composition such as than defined previously.
