Abstract: The invention relates to novel shower gels and hair shampoos containing a neutralised tenside combination of alkyl polyglycol ether carboxylate, alkyl ether sulphate and fatty acid amidopropyl betaine and the customary auxiliary and base substances which the average degree of ethoxylation of the alkyl polyglycol ether carboxylate is 2-5.

Abstract: The present invention provides a shower gel having a tenside and other conventional adjuvants, for example thickening agents, electrolyte salts, perfume, coloring materials, disinfection agents and protein hydrolysates, as well as water as a solvent, wherein, as the tenside, there is used a combination of an amidopropylbetaine and a fatty acid methyltauride.

Abstract: The present invention provides a process for preparing polycarboxylic acid imidazolines of the general formula: ##STR1## wherein X is --Cl, --OH, --O--SO.sub.3 H, --O--PO.sub.3 H.sub.2, --O--CH.sub.2 --CH.sub.2 --COOH, --NH.sub.2, --NHalk or --N(alk).sub.2, alk being an alkyl radical containing up to 6 carbon atoms, n is a whole number of from 2 to 4, R is a C.sub.8 -C.sub.18 hydrocarbon radical which is straight-chained, branched, saturated or one to three times unsaturated, m is a whole number of from 2 to 5, R' is a hydrogen atom or a carboxyl group and R" is a hydrogen atom or a methyl radical. In the process, a compound of the formula ##STR2## in which R, X and n are as defined above, is condensed with about a 2- to 5-fold excess of acrylic acid, methacrylic acid, maleic acid or a mixture thereof.

Abstract: The present invention provides a shower gel or hair shampoo which includes a neutralized tenside combination of alkyl polyglycol ether carboxylate, alkyl sulphate and fatty acid amidopropylbetaine, as well as conventional adjuvant and carrier materials, wherein the average degree of ethoxylation of the alkyl polyglycol ether carboxylate is from 2 to 5 ethoxy groups.
