ABSTRACT:
Carboxymethylated derivatives of polysaccharide compounds such as starch are disclosed which have improved sequestering properties and are useful as water softeners as well as detergency builders in detergent compositions. The compounds are water-soluble and have from 0.5 to 3 hydrogen atoms of the hydroxyl groups per monomeric six carbon glucose unit entirely or partially substituted with at least 2 neutralized or non-neutralized carboxyl groups.
Built detergent compositions containing the water-soluble carboxymethylated derivatives of polysaccharide compounds with organic water soluble surfactants are also disclosed. The compositions exhibit improved sequestering power.
