Patent

CA 2250837

The present invention relates to a composition and process for preparing such a composition which provides stabilised betaine ester compounds of active alcohols in an acidic environment. In particular, it relates to an aqueous acidic composition comprising: a) a betaine ester of an active alcohol which, at a concentration of from 0.01 % to 10 % by weight in said composition, is predominantly in the form of micelles and/or is capable of being incorporated into micelles, b) a surfactant, said composition comprising an acidic material in sufficient amount to render the pH of the composition of less than 7.

Cette invention se rapporte à une composition et à un procédé pour préparer une telle composition, par laquelle on forme des composés d'ester de bétaïne stabilisés d'alcools actifs dans un milieu acide. Cette invention se rapporte en particulier à une composition acide aqueuse contenant: (a) un ester de bétaïne d'un alcool actif qui, à une concentration comprise entre 0,01 % et 10 % en poids de cette composition, est présent essentiellement sous la forme de micelles et/ou est capable d'être incorporé dans des micelles; (b) ainsi qu'un tensioactif; cette composition comprenant une substance acide en quantité suffisante pour rendre le pH de ladite composition inférieur à 7.
