L'invention concerne des compositions cosmétiques qui présentent des avantages accrus lors de l'application sur des tissus et des fibres de kératine et permettent cependant d'éviter les effets négatifs associés aux compositions connues à ce jour. Les compositions cosmétiques de l'invention comprennent un phospholipide, un copolymère PVP et un latex insoluble à l'eau et permettent d'épaissir, de séparer et de revitaliser la fibre pileuse tout en assurant une longue tenue. Les inventeurs ont également trouvé que lesdites compositions sont également utiles pour d'autres produits cosmétiques destinés à des tissus à structure kératinique comme la peau tels que, rouges à lèvres, fonds de teint, mascaras, eyeliners, produits pour contour des lèvres, fards à paupières, fards à joues, pour lesquels il est nécessaire d'appliquer une fine couche de produit cosmétique filmogène longue tenue.
