Abstract

Liquid phosphate-free, regulated-foam washing agent compositions comprising: PA1 A. from 15% to 60% by weight of a mixture of ethylene oxide adducts to aliphatic organic compounds having from 12 to 30 carbon atoms and a replaceable hydrogen atom with degrees of ethoxylation of 2 to 6 and 8 to 20 where the ratio of the 2 to 6 ethoxylated compound to the 8 to 20 ethoxylated compound in the mixture is from 1:5 to 2:1, PA1 B. from 0.2% to 8% by weight of foam inhibitors selected from the group consisting of non-surface-active foam inhibitors, soap and mixtures thereof in a weight ratio of non-surface-active foam inhibitors to soap of from 1:2 to 1:4, PA1 C. from 0.3% to 15% by weight of at least one water-soluble salt of an organic compound capable of sequestering calcium, said organic compound being selected from the group consisting of aminoalkane polycarboxylic acids, carboxymethyl derivatives having at least 2 carboxyl groups, polymeric carboxylic acid compounds with a molecular weight of over 350 and at least one carboxyl group per each molecular weight unit of 175, phosphonoalkane polycarboxylic acids, aminoalkanepolyphosphonic acids and hydroxyalkanepolyphosphonic acids, PA1 D. …
