    Abstract: A process for the preparation of a stable emulsion of at least one water-immiscible liquid phase L in an aqueous phase D is described which comprises mixing the liquid phase or phases L with a dispersion of spheres in an aqueous phase D, the spheres having an average diameter of 0.025 to 5 microns and consisting of substantially concentric lipid laminae encapsulating an aqueous phase E between them, the lipid or lipids constituting the laminae being ionic or nonionic amphiphilic substances capable of forming a lamellar phase in water, and subjecting the whole to mechanical agitation so as to disperse the phase (or phases) L in the phase D in the form of droplets having an average diameter of 0.1 micron to a few microns.

    Abstract: This cosmetic composition contains from 0.05 to 3% by weight of at least one amphoteric surface-active agent chosen from the compounds of formulae (I), (IV), (V), (VI) and (VII), from 0.05 to 3% by weight of at least one anionic surface-active agent chosen from the compounds of formula (VIII) to (XI) and from 0.02 to 8% by weight of at least one nonionic polymer (poly- beta -alanine, alkyl and hydroxyalkylcelluloses, starch derivatives) and/or anionic polymers (polyacrylamide, polyacrylamidosulphonic acid and its salts, sodium polymethacrylate), the total concentration of surface-active agent(s) not exceeding 5% by weight. Despite this reduced concentration of surface-active agent(s), which endows it with a satisfactory innocuousness, this composition has an excellent cleansing power. +TR R1 to R13, R'1, n, m, and p have specified meanings.
