Abstract
Abstract The use of sulfosuccinate derivatives of carbohydrates such as starches, sucrose, cellulose, glycogen, hemicellulose, gums, as biodegradable builders in detergent compositions. The aforementioned compounds can be substituted in detergent compositions for existing builders containing phosphorus or nitrogen without impairing the efficiency of such detergent compositions.
