Abstract
Official abstract text for this publication.
An alkaline detergent is described which includes the use of polycarboxylic acid copolymers or salts thereof in combination with alkali metal hydroxide. The detergent composition reduces spotting and filming and prevents hard water scale accumulation between 145-180 degrees Fahrenheit and with a pH of 10.5 to about 13.
First claim
Opening claim text (preview).
What is claimed is: 1. A detergent composition comprising: about 100 ppm to about 22,000 ppm of an alkali metal hydroxide; about 1 ppm to about 1500 ppm of a nonionic surfactant; and about 10 ppm to about 6,000 ppm of at least one polycarboxylic acid copolymer or salt thereof with the following structure wherein: a.) The molecular weight is from about 1,000 to 50,000…
