Abstract
Abstract An alkaline builder-free detergent composition contains a partially neutralized succinic acid derivative of the formula (1): ##STR1## wherein R is a saturated or unsaturated hydrocarbon group of 8-18 carbon atoms, and X and Y each are hydrogen, an alkali metal, ammonium or an alkanolamine, characterized in that when the composition is diluted with water thereby to give a succinic acid derivative content of 0.5 wt. %, the solution has a pH of 5.5-8.0.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A detergent composition containing from 3 to 95 wt. % of partially neutralized succinic acid derivative having the formula ##STR4## wherein R is a saturated or unsaturated hydrocarbon group having from 8 to 18 carbon atoms, and X and Y are each hydrogen, an alkali metal, ammonium or an alkanolamine, with the proviso that from 0.2 to 0.9 equivalents of the groups COOX and COOY are alkali metal, ammonium or alkanolamine carboxylate groups and the remainder are carboxyl groups; the balance of said detergent composition being conventional ingredients of liquid or granular detergents, said ingredients being different from said derivative, with the provisos that said detergent composition is free of alkaline builder and an aqueous solution of said detergent composition containing 0.5 wt. % of said derivative has a pH of 5.5 to 8.0.
Claim 2
Dependent Claim
134 words
A detergent composition containing from 3 to 95 wt. % of partially neutralized succinic acid derivative having the formula ##STR4## wherein R is a saturated or unsaturated hydrocarbon group having from 8 to 18 carbon atoms, and X and Y are each hydrogen, an alkali metal, ammonium or an alkanolamine, with the proviso that from 0.2 to 0.9 equivalents of the groups COOX and COOY are alkali metal, ammonium or alkanolamine carboxylate groups and the remainder are carboxyl groups; the balance of said detergent composition being conventional ingredients of liquid or granular detergents, said ingredients being different from said derivative, with the provisos that said detergent composition is free of alkaline builder and an aqueous solution of said detergent composition containing 0.5 wt. % of said derivative has a pH of 5.5 to 8.0.
