Foaming oil-in-water emulsion based on nonionic surfactants, a fatty phase and a crosslinked cationic or anionic polymer, and its use in topical applications

摘要

A foaming oil-in-water emulsion in the form of a cream comprising, in an aqueous medium, at least:PPa) from 5 to 20% of an exclusively nonionic surfactant system comprising at least one foaming nonionic surfactant;PPb) 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:PP15. 5(J/cm.sup.3).sup.1/2 ≦dD≦ 18. 0(J/cm.sup.3).sup.1/2 andP P0(J/cm.sup.3).sup.1/2 . ltoreq.dA≦6.5(J/cm.sup.3).sup.1/2 withPPdA=(dP.sup. 2 + dH.sup.2).sup.1/2PPc) 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.
