摘要:
A cosmetic composition which is a stabilized, oil-in-water dispersion of spheres in an external aqueous phase. The spheres are organized molecular layers of a nonionic amphiphilic lipid material encapsulating an internal aqueous phase. The external aqueous phase, containing an oil, is free of any surface active emulsifying agent.

摘要:
A perfume composition, with an aqueous phase, having a high concentration of perfume, which contains:a) vesicles which are obtained from at least one non-ionic lipid derived from a linear or branched polyglycerol, associated with a stabilizer present in a proportion of 1 to 10% by weight based on the lipid, the vesicles having an average diameter of between 0.01 .mu. and 1 .mu. and the lipids which form the vesicles representing 0.2 to 4% by weight of the total composition; andb) a perfume in the form of droplets having an average diameter of between 0.1 .mu. and 1 .mu. and being present in the composition in amounts of between 3 and 20% by weight based on the total composition, the total ratio of the lipid or lipids of the vesicles to the perfume being between 0.05 and 0.2.
摘要:
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.

摘要:
The invention relates to a composition consisting of a dispersion in an aqueous medium D of niosome and/or liposome spherules, within which an aqueous phase E is encapsulated, at least one portion of the spherules being niosomes; the lipids forming spherules constituting from 2 to 10% of the weight of the composition; in at least one of the phases E and D there is dissolved at least one water-soluble polyamide polymer having a molecular weight between 1,000 and 200,000, at a concentration of 0.01 to 5% by weight relative to the total weight of the composition. Usable in cosmetics or pharmaceuticals.
摘要:
An anhydrous or aqueous cosmetic composition contains, as an oily phase, the fat of Shorea robusta or a mixture of the fat of Shorea robusta and a cosmetically acceptable oil, another fat or wax. The cosmetic composition can be a cream, an emulsion or any other composition containing or comprising an oily phase.
摘要:
A stable oil-in-water emulsion for use in cosmetic or pharmaceutical compositions includes as the emulsifying system therefor a combination of (i) a mixture of (1) mono- or di-alkyl carboxylates of .alpha.-methyl glucoside, or a mixture thereof and (2) mono- or di-alkyl carboxylates of .alpha.-methyl glucoside polyoxyethylenated with 10-30 moles of ethylene oxide, or a mixture thereof, the said alkyl moiety of each being linear or branched and having from 11-21 carbon atoms, (ii) lecithin, (iii) egg yolk oil, and (iv) a polyacrylic type polymer.
摘要:
A cosmetic preparation contains, as a fatty phase, karite oil having the following characteristics: palmitic acid (C.sub.16), 3-5 percent; stearic acid (C.sub.18), 22-30 percent; oleic acid (C.sub.18:1), 55-65 percent; linoleic acid (C.sub.18:2), 0.5-1.5 percent; and arachidic acid (C.sub.20), 0.5-1.5 percent, said percentages being based on the total weight of fatty acid present in said karite oil, a viscosity of 100-300 centipoises, a melting point of 5.1.degree.-5.4.degree. C., a crystallization temperature of 2.9.degree.-3.degree. C. and an unsaponifiable content of 1.2-1.5 percent.
