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 1 wt-% and about 20 wt-% of a phosphinosuccinic acid derivative comprising a phosphinosuccinic acid and mono-, bis and oligomeric phosphinosuccinic acid adducts; between 65 wt-% and about 90 wt-% of an alkalinity source selected from the group consisting of an alkali metal hydroxide, carbonate, metasilicate, and silicate; and between about 10 wt-% and about 20 wt-% of water;wherein a use solution of the detergent composition has a pH between about 9 and 12.5.
