The invention relates to a polymer component which consists of a polymer or of a plurality of different polymers, and comprises at least one polyurethane, the polymer or at least one of the polymers having acid groups that are partially neutralized with at least one inorganic base and partially with at least one organic base. The invention also relates to cosmetic or pharmaceutical agents that contain such a polymer component and to a method for modifying the mechanical properties of such a polymer component, at least one inorganic base and at least one organic base being used for neutralization.
L'invention concerne un composant polymère constitué d'un polymère ou d'une pluralité de polymères différents, et comprenant au moins un polyuréthanne. Le polymère ou au moins un des polymères présente des groupes acides qui sont partiellement neutralisés par au moins une base inorganique et partiellement par au moins une base organique. L'invention concerne également des agents cosmétiques ou pharmaceutiques qui contiennent ledit composant polymère et un procédé permettant la modification des propriétés mécaniques dudit composant polymère, selon lequel au moins une base inorganique et au moins une base organique sont utilisées pour la neutralisation.
