First Claim
Patent Images
1. A method of cleaning while preventing hard water scale accumulation on a treated surface comprising:
- generating a use solution of a detergent composition within a ware washing machine,applying the use solution of the detergent composition to a substrate surface,wherein the detergent composition comprises 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 and an alkalinity source selected from the group consisting of an alkali metal hydroxide, carbonate, metasilicate, silicate, and combination thereof, andwherein the detergent composition is effective for preventing the formation, precipitation and/or deposition of hard water scale on the surface;
wherein the use solution of the detergent composition has a pH greater than 9; and
the composition is a detergent composition, contains more of the alkalinity source than the phosphinosuccinic acid derivative in terms of weight percentage, and does not contain a bleaching agent.

Abstract
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.
