Abstract

L'invention vise à améliorer le pouvoir détergent de détergents et de produits de nettoyage, en particulier sur des salissures grasses et/ou huileuses. Ce but est atteint essentiellement en incorporant des copolymères contenant des unités sulfobétaïne dérivées d'acides carboxyliques éthyléniquement insaturés et des esters d'acide hydroxyalkyl(méth)acrylique.
