Abstract:
An alkaline detergent is described which includes the use of a copolymer in combination with an alkali metal hydroxide. The detergent maintains cleaning functions and also prevents hard water scaling, for example at application temperatures of between 145-180 degrees Fahrenheit and with a pH of 9.5 to about 13.
