CYSTEIC MONOSUCCINATE SEQUESTRANTS AND DETERGENT COMPOSITIONS CONTAINING THEM

摘要

Cysteic monosuccinic acid and alkali metal, alkaline earth metal, ammonium and substituted ammonium salts thereof useful in detergent compositions as builders. The compounds can be produced by reacting a monoalkyl maleate with a cysteic acid salt or by reacting a bromosuccinate with a cysteic acid salt. The compounds show good biodegradability and good builder properties in a detergent composition. A detergent composition containing about 5 % to 80 % by weight of the compounds has good detergency properties, including stain release properties.
