A novel class of biodegradable detergents having improved resistance to precipitation in hard water are the water-soluble ionic salts or nonionic esters or amides of alkanoic acids which are substituted by at least one group containing an electronegative atom, said substitution being attached to a carbon atom 2 to 5 positions from the carboxyl carbon. Gamma-substituted alkanoic acid derivatives are preferred.
