Abstract

Nitrogen-free thickeners in aqueous surfactant solutions comprising polyethoxylates of mono- and/or polyunsaturated C.sub.12 -C.sub.22 fatty alcohols having an average degree of ethoxylation of 2 to 5, which also contain 1 to 2 terminal propylene oxide groups attached by condensation instead of the corresponding number of ethylene oxide groups. The products may also be used in admixture with dissolved inorganic electroltye salts and with polyethoxylates of saturated fatty alcohols. These surfactant solutions are useful in the formulation of personal hygiene preparations such as hair shampoos, foam baths, shower baths, handwashing pastes and the like.
