Abstract:
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 a nonionic surfactant system consisting of at least one foaming nonionic surfactant and at least one emulsifying nonionic surfactant, wherein said at least one foaming nonionic surfactant is selected from: i) the compounds of formula (I): in which: R represents an aliphatic, cycloaliphatic or arylaliphatic radical or a mixture of radicals having from 7 to 21 carbon atoms, wherein the aliphatic chains are saturated or unsaturated, linear or branched, and may contain sulphur or oxygen atoms; and n represents any integer or fraction greater than 1 and less than or equal to 10 and denotes the degree of polymerization; ii) the compounds of formula (II) R1O(G)p â€ƒin which R1 is a monovalent hydrocarbon chain containing from 1 to 30 carbon atoms, G is a saccharide containing from 5 to 6 carbon atoms and p is a statistical average value ranging from 1 to 6; iii) polydimethylsiloxanes containing glucoside groups and polydimethylsiloxanes containing alkylphosphobetaine groups; and iv) mixtures of the above compounds; and wherein said at least one emulsifying nonionic surfactant is present in an amount up to 2% by weight and is selected from oxyethylenated alkylphenols; 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 has solubility parameters dD, dP and dH according to Hansen's solubility space which satisfy the conditions: 15.5 (J/cm3)Â½&lE;dD&lE;18.0 (J/cm3)Â½and 0 (J/cm3)Â½&lE;dA&lE;6.5 (J/cm3)Â½with dA=(dP2+dH2)Â½; and c) 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; wherein said copolymer does not comprise copolymers containing a majority fraction of at least one olefinically unsaturated C3-C6 acid and a minority fraction of at least one ester of an olefinically unsaturated C3-C6 acid with a C10-C30 alcohol.
