Alkyl ether carboxylic acid taurides

High molecular weight protein/fatty acid condensation products obtained by reaction of one mole of a protein hydrolysate of average molecular mass 3,000 to 7,000 with 0.5 to 3, preferably 2 to 2.5, moles of a C.sub.12 -C.sub.18 -fatty acid chloride in aqueous medium at a pH of 7 to 12. These protein/fatty acid condensation products are distinguished by eliciting no mucosal irritation whatever. They are therefore outstandingly suitable as surfactants for mild washing and cleansing agents.

High molecular weight protein/fatty acid condensation products which are

Fatty acid-modified polysters composed of polyalkylene oxide and dimerized fatty acids, of the formula ##STR1## in which R is C.sub.8 -C.sub.22 -alkyl or C.sub.8 -C.sub.22 -alkenyl, preferably C.sub.12 -C.sub.18 -alkyl, R.sup.1 is the alkyl skeleton of a dimerized fatty acid having 22 to 42, preferably 34 carbon atoms, A is --C.sub.2 H.sub.4 -- or --C.sub.3 H.sub.6 --, n is a number from 1 to 5, preferably 1 to 3, and x is a number from 20 to 150, preferably 23 to 140. These are prepared by simultaneous reaction of the underlying dimerized fatty acid, polyalkylene oxide and fatty acid. The polyesters obtained are used as agents for increasing the viscosity of surfactant-containing cosmetic, pharmaceutical and industrial products.

Method of increasing viscosity with fatty acid-modified polyesters and
