Abstract RU 2128504 C1

FIELD: medicine, cosmetics, dermatology. SUBSTANCE: invention relates to an emulsion of type "oil-in-water" formed by oily globules. Each globule has lamellar fluidized protective envelope dispersed in an aqueous phase. Each oily globule containing at least one lipophilic cosmetically or dermatologically active compound is covered uniformly by monolamellar or oligolamellar layer. Layer is prepared from at least one lipophilic surface-active substance, hydrophilic surface-active substance and at least one ionic amphiphilic lipid to obtain pH value of an emulsion from 5.5 to 7.5. Oily globules covered by protective envelope have an average diameter less 500 nm, preferably 200 nm. EFFECT: improved penetration of substances and stability. 28 cl
