Abstract
A foam-regulated washing composition based on olefin-sulfonates and/or salts of .alpha.-sulfo-fatty acid esters and phosphorus-free complexing builder salts, especially for drum washing machines and also at wash temperatures of over 90.degree.C characterized by a content of: PA1 A. a surface-active component of 50 to 100% by weight of said component of olefin sulfonates and/or salts of .alpha.-sulfo-fatty acid esters and 0 to 50% by weight of said component of other anionic surface-active compounds of the sulfonate and sulfonate type and/or non-ionic surface-active compounds with good biodegradability and low toxicity; PA1 B. a soap of saturated fatty acids having essentially 18 to 24 carbon atoms; and PA1 C. a complexing builder salt component of 75 to 100% by weight of said component of a high-molecular-weight polyalkylene-polycarboxylic acid copolymer of a lower alkene with an ethylenically unsaturated dicarboxylic acid or tricarboxylic acid and 0 to 25% by weight of said component of other complexing builder salts such as sodium tripolyphosphate. PAC THE PRIOR ART With regard to the question of protection of the environment, washing compositions with components having a biologi…
