ABSTRACT:
Oil-in-water emulsions show improved viscosity behavior, more especially an increased viscosity under shear stress, when the continuous aqueous phase contains a combinations of hydrocolloids comprising: (a) at least one water-soluble nonionic cellulose ether; and (b) a cross-linked acrylic acid polymer or copolymer having a weight average molecular weight of from 1,000,000 to 5,000,000; in the form of a water-soluble salt in a quantitative ratio a:b of from 9:1 to 1:9. Cosmetic O/W-creams according to the invention show more "body" when applied to and spread over the skin.
