ABSTRACT:
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.
