Abstract
Abstract Glycerine derivatives of formula A (wherein R l , R 2 and R 3 , which may be the same or different, each represents a hydrogen atom or a group of formula -CH(COOH)-CH 2 -COOH, with the proviso that at least one of R 1 , R 2 and R 3 represents other than a hydrogen atom), salts thereof and mixtures of two or more said compounds or salts are described. Such compounds are useful as detergent builders and are nitrogen and phosphorus free.
