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.
