DETERGENT COMPOSITION COMPRISING PHOSPHINOSUCCINIC ACID ADDUCTS AND METHODS OF USE

摘要

Detergent compositions effective for controlling hard water scale accumulation are disclosed. Detergent compositions employing phosphinosuccinic acid and mono-, bis- and oligomeric phosphinosuccinic acid (PSO) derivatives with alkali metal carbonate and/or alkali metal hydroxide reduce had water scale accumulation on treated surfaces at alkaline conditions between about pH of 9 and 12.5. Methods employing the detergent compositions and preventing hard water scale accumulation are also provided.

1: A detergent composition comprising:
between about 0.01 wt-% and about 40 wt-% of a phosphinosuccinic acid derivative comprising a phosphinosuccinic acid and mono-, bis- and oligomeric phosphinosuccinic acid adducts; between about 10 wt-% and about 90 wt-% of an alkalinity source selected from the group consisting of an alkali metal hydroxide, carbonate, metasilicate, silicate, and combinations of the same; andwater;wherein a use solution of the detergent composition has a pH greater than 9.
