Importance of alkalis, dispersants and sequestrants in building action

Abstract

AbstractThe builder effects of a variety of alkalis, dispersants and sequestrants on detergency have been examined by changing builder compositions of detergents. The detergent formulated with an alkali, a dispersant and a sequestrant exhibits a high detergency, comparable to the standard detergent built with sodium tripolyphosphate. When any one of these three components is omitted, the detergency does not reach a satisfactory value. Further, when any two of them are eliminated, the detersive power is further reduced. Using these results the importance in building action of the combination of the three builder components has been discussed.
