Abstract

A forming oil-in-water emulsion in the form of a cream comprising, in an aqueous medium, at least:

a) from 5 to 20% of an exclusively nonionic surfactant system comprising at least one foaming nonionic surfactant;

b) from 10 to 50% of an oily phase containing at least one water-insoluble oil whose solubility parameters dD, dP and dH according to Hansen'"'"'s solubility space satisfy the conditions:

15.5 (J/cm³)^½≦dD≦18.0 (J/cm³)^½

and

0 (J/cm³)^½≦dA≦6.5 (J/cm³)^½

dA=(dP²+dH²)^½

c) and, as a gelling agent, at least one crosslinked homopolymer or copolymer formed from at least one cationic or anionic monomer containing ethylenic unsaturation and from a crosslinking agent containing polyethylenic unsaturation. This composition is useful in cosmetics, dermatology and hygiene as a base for cleansing products for the skin, the hair, the mucous membranes and the scalp.
