Abstract

La présente invention se rapporte à une composition comprenant : (a) au moins un premier polymère formant film liposoluble sélectionné parmi les (co)polymères de vinylester ; (b) au moins un second polymère formant film liposoluble sélectionné parmi le polyester de poly(alcool de vinyle) et l'acide gras ; (c) au moins une huile ; et (d) au moins une cire, la quantité du (a) premier polymère formant film étant de 0,4 % à 3,0 % en poids, préférentiellement de 0,6 % à 2,8 % en poids, et plus préférentiellement de 0,8 % à 2,6 % en poids, par rapport au poids total de la composition, et la quantité du (b) second polymère formant film étant de 0,2 % à 2,0 % en poids, préférentiellement de 0,3 % à 1,8 % en poids, et plus préférentiellement de 0,4 % à 1,6 % en poids, par rapport au poids total de la composition. La composition selon la présente invention peut fournir des fibres de kératine de sorte que les cils présentent des effets cosmétiques, tels que des effets d'accroissement du volume, qui peuvent durer longtemps, sans bavure, tandis que la composition selon la présente invention peut être facilement retirée des fibres de kératine.
