Cosmetic compositions containing block copolymers and corresponding long-wearing cosmetic product system

摘要

A cosmetic composition containing at least one block copolymer having at least one hard segment and at least one soft segment, at least one tackifier component, at least one solvent capable of solubilizing the soft segment, and optionally, at least one colorant, and wherein the at least one hard segment has a T<Sub>g</Sub> of about 50 °C or more and the at least one soft segment has a T<Sub>g</Sub> value of about 20 °C or less.
It also relates to the use of this composition as a top-coat composition in a method of making-up a keratinous substrate involving: (a) providing a keratinous substrate; (b) applying a basecoat composition onto the keratinous substrate, the basecoat composition comprising: (i) at least one polyorganosiloxane containing polymer, (ii) at least one silicone film former; (iii) at least one volatile oil; and (iv) at least one colorant; and (c) applying said topcoat composition over top of the basecoat composition.
