Abstract

A foaming 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/cm.sup.3).sup.1/2 ≦dD≦18.0(J/cm.sup.3).sup.1/2  and

0(J/cm.sup.3).sup.1/2 ≦dA≦6.5(J/cm.sup.3).sup.1/2  with

dA=(dP.sup.2 +dH.sup.2).sup.1/2

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.

Claims

1. A foaming oil-in-water emulsion in the form of a cream, which comprises, in a cosmetically acceptable aqueous medium, at least:

(a) from 5 to 20% by weight, relative to the total weight of the composition, of an exclusively nonionic surfactant system comprising at least one foaming nonionic surfactant chosen from dodecanediol polyglycerolated with 3.5 mol of glycerol, a polydimethylsiloxane containing a polyoloside group, a C₈ -C₁₆ -alkylpolyglucoside with a degree of polymerization of 1.4, and an oxyethylenated hydrogenated ricinoleic triglyceride;

(b) from 10 to 50% by weight, relative to the total weight of the composition, of an oily phase comprising from 85 to 100% by weight of at least one water-insoluble oil, wherein said at least one water-insoluble oil is chosen from liquid fraction of Karite butter, 2-octyldodecyl erucate, jojoba oil, 2-octyldodecyl stearate, isostearyl isostearate, 2-octyldodecyl benzoate, 2-ethylhexyl palmitate, and sesame oil; and

(c) as 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 wherein said gelling agent is chosen from acrylic acid homopolymers crosslinked with an allyl ether of an alcohol, copolymers of ammonium acrylate and of acrylamide, and crosslinked homopolymers of dimethylaminoethyl methacrylate quaternized with methyl chloride.

2. An emulsion according to claim 1, which comprises:

a) from 5 to 10% by weight, relative to the total weight of the composition, of an exclusively nonionic surfactant system comprising at least one foaming nonionic surfactant; and

b) from 10 to 30% by weight, relative to the total weight of the composition, of an oily phase comprising at least one water-insoluble oil.

3. An emulsion according to claim 1, wherein said gelling agent is present in active material concentrations ranging from 0.8 to 8% by weight relative to the total weight of said emulsion.

4. An emulsion according to claim 1, which further comprises at least one emulsifying nonionic surfactant, said at least one emulsifying nonionic surfactant being different from said at least one foaming nonionic surfactant.

5. An emulsion according to claim 1, which further comprises at least one thickening agent.
