Abstract

A paste-form detergent and process of making the detergent is presented. The detergent is composed of: 5 to 30 percent by weight of an ethoxylated alcohol of the formula R.sup.1 --(OC.sub.2 H.sub.4).sub.m --OH where R.sup.1 is an alkyl or alkenyl group containing 9 to 15 carbon atoms and the average degree of ethoxylation m is 1 to 8; 1 to 20 percent by weight of an ethoxylated alcohol of the formula R.sup.2 --(OC.sub.2 H.sub.4).sub.n OH where R.sup.2 is an alkyl or alkenyl group containing 12 to 22 carbon atoms and the average degree of ethoxylation n is 3 to 14, and n is greater than m by at least 1.0; 1 to 20 percent by weight of an alcohol or alkyl ether corresponding to the formula R.sup.3 --O--R.sup.4 where R.sup.3 is an alkyl or alkenyl group containing 6 to 22 carbon atoms and R.sup.4 is hydrogen or an alkyl group containing 1 to 6 carbon atoms; 20 to 80 percent by weight of an alkalizing agent, and 0 to 15 percent by weight of an organic builder. The paste-form detergent is useful in institutional laundries and results in a reduced tendency to foam at the rinsing and pressing stage.
