摘要

PROBLEM TO BE SOLVED: To provide a lip treatment composition which is comfortable to apply, wear, and which has long lasting shine/gloss.;SOLUTION: The invention relates to a cosmetic composition contains at least one block copolymer having at least one hard segment and at least one soft segment, at least one tackifier component, a solvent mixture, and optionally, at least one colorant, and wherein the at least one hard segment has a T_gvalue of ≥50°C, the at least one soft segment has a T_gvalue of ≤20°C, and wherein the solvent mixture contains at least one solvent capable of solubilizing the at least one hard segment. The invention also relates to a use of the composition as a topcoat composition in a cosmetic method of making-up a keratinous substrate, that involves: (a) providing a keratinous substrate; (b) applying a basecoat composition onto the keratinous substrate, wherein the basecoat composition comprising (i) at least one (co)polymer comprising at least one organosiloxane unit, (ii) at least one silicone film former, (iii) at least one volatile oil and (iv) at least one colorant; and (c) applying a topcoat composition over top of the basecoat composition.;COPYRIGHT: (C)2012,JPO&INPIT
