PROCESS FOR THE PREPARATION OF DETERGENT COMPOUNDS CONTAINING SODIUM CARBONATE AND CALCITE AND A COPOLYMER TO REDUCE THE DEPOSITION OF INSOLUBLE MATERIALS IN FABRICS

摘要

A detergent composition containing a detergent active, sodium carbonate and calcite also contains a copolymer to reduce deposition of insoluble material on fabrics. The copolymer is derived from a carboxylic monomer and a non-carboxylic monomer, with the non-carboxylic monomer being in excess. A 3:1 copolymer of sulphonated styrene and maleic anhydride is exemplified.
