Abstract

A paste-form detergent for use in institutional laundries free from synthetic anionic surfactant of the alkyl benzenesulfonate type containing 5% to 30% by weight of an ethoxylated alcohol corresponding to formula (I): EQU R.sup.1 --(OC.sub.2 H.sub.2).sub.m --OH (I) in which R.sup.1 is an alkyl or alkenyl group containing 12 to 14 carbon atoms and m has a value of 1 to 8, 1% to 20% by weight of an ethoxylated alcohol corresponding to formula (II): EQU R.sup.2 --(OC.sub.2 H.sub.2).sub.n --OH (II) in which R.sup.2 is an alkyl or alkenyl group containing 12 to 22 carbon atoms and n has a value of 3 to 14, with proviso that n is greater than m by at least 1.0, 20% to 80% by weight of alkalizing agent, 1% to 20% by weight of long-chain alcohol or alkyl ether corresponding to formula (III): EQU R.sup.3 --O--R.sup.4 (III) in which R.sup.3 is an alkyl or alkenyl group containing 8-22 carbon atoms and R.sup.4 is hydrogen or an alkyl group containing 1 to 6 carbon atoms, and up to 5% by weight of organic builder of the polymeric polycarboxylate type.
