Abstract

La présente invention concerne une base pour cosmétique comprenant une résine non ionique, qui est soluble dans l’eau, dans l’alcool et les gaz de pétrole liquéfiés (GPL), facilite l'ajustement d’une propriété de base pour cosmétique et est utile, en particulier, comme base pour cosmétique capillaire. La base pour cosmétique selon l’invention est une résine non ionique composée d’un polymère d’un composant monomère éthylénique non saturé (A) comprenant un monomère non ionique non saturé (a). Dans le monomère non ionique non saturé (a), du N,N-diméthylacrylamide (a1) représenté par la formule chimique suivante (1) est ajouté comme composant essentiel. Cette base pour cosmétique est une résine non ionique, ce qui rend improbable le risque d’incompatibilité, même en cas d’utilisation avec une autre résine. En outre, cette résine présente une bonne solubilité dans différents types de solvants pour la base. La solubilité de la base pour cosmétique dans différents types de solvants, les propriétés de base pour cosmétique comme le point de transition vitreuse ou l’adhésivité sont faciles à ajuster.
