Abstract
Disclosed is trisulfosuccinic acid and salts thereof described by the formula: ##STR1## where one of R.sub.1, R.sub.2, R.sub.3 or R.sub.4 is hydrogen and the remainder are SO.sub.3 M; and where M may be the same or different cation selected from hydrogen or an alkali metal. These compounds may be prepared by aqueous liquid phase reaction of a dihalomaleic anhydride, alkali metal hydroxide and an alkali metal sulfite and are useful as detergent builders.

A detergent composition consisting essentially of:
- a. 100 parts by weight of a surfactant selected from the group consisting of anionic, cationic, and non-ionic synthetic surfactants;
- and
- b. 10 to 1,000 parts by weight of trisulfosuccinic acid or its salts described by the formula:
- ##STR4## where one of R.sub.1, R.sub.2, R.sub.3 or R.sub.4 is a hydrogen ion and the remainder are SO.sub.3 M;
- and where M may be the same or different cation selected from hydrogen or an alkali metal.
A method of increasing the detersive effect of a surfactant in an aqueous media which comprises adding to 100 parts by weight of surfactant containing aqueous media 0.01 to 0.2 parts by weight of trisulfosuccinic acid or its salts described by the formula:
- ##STR5## where one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is hydrogen and the remainder are SO.sub.3 M;
- and where M may be the same or different cation selected from hydrogen or an alkali metal.
