Abstract:
The invention relates to an oil-in-water nanoemulsion having an oily phase dispersed in an aqueous phase, the oil globules of which have a number-average size of less than 100 nm, containing: (i) at least one amphiphilic lipid comprising at least one nonionic amphiphilic lipid, and optionally at least one ionic amphiphilic lipid, the oily phase and the amphiphilic lipid being present at a content such that the oily phase/amphiphilic lipid weight ratio ranges from 3 to 10, and (ii) at least one hydroxylated urea derivative. Application in cosmetics, dermatology, and ophthalmology.
Abstract:
The invention relates to a composition containing at least one hydrophilic active principle and at least one amphiphilic polyisobutylene polymer. The invention also relates to the use of such a polymer for stabilizing an oxidation-sensitive hydrophilic active principle, in particular in the aqueous phase. The present invention also relates to the uses of this composition.
Abstract:
A nanoemulsion, the oil globules of which have an average size of less than 100 nm, comprising an anionic surfactant chosen from alkyl ether citrates and at least one oil having a molecular weight of greater than 400, the ratio by weight of the amount of oily phase to the amount of surfactant ranging from 2 to 10. The emulsion obtained is transparent and stable on storage. It can comprise large amounts of oil while retaining good transparency and while having good cosmetic properties. It can constitute a composition for topical use, a pharmaceutical composition or an ophthalmological composition. The invention also relates to the use of the nanoemulsion according to the invention in the cosmetics and dermatological fields, in particular for moisturizing the skin and/or mucous membranes, as well as for treating the hair, and in the ophthalmological field, as an eye lotion for treating the eyes.
Abstract:
The present invention relates to nanocapsules consisting of a lipid core forming or containing a lipophilic active principle, and of a water-insoluble continuous envelope comprising at least one dendritic polymer of polyester type containing optionally modified terminal hydroxyl functions, and to cosmetic and/or dermatological compositions containing the said nanocapsules based on dendritic polymers.
Abstract:
The present invention relates to a nanoemulsion, the oil globules of which have an average size of less than 100 nm, comprising (1) a surfactant which is solid at a temperature of less than or equal to 45° C., which surfactant is chosen from sorbitan fatty esters and oxyethylenated sorbitan fatty esters, (2) at least one oil having a molecular weight of greater than 400 and (3) at least one ionic amphiphilic lipid chosen from the group formed by the alkaline salts of dicetyl and dimyristyl phosphate, the alkaline salts of cholesterol sulphate, the alkaline salts of cholesterol phosphate, lipoamino acids, the sodium salts of phosphatidic acid, cationic amphiphilic lipids and alkylsulfonic derivatives, the ratio by weight of the amount of oily phase to the amount of surfactant ranging from 2 to 10. The surfactant used is, for example, chosen from sorbitan monostearate, sorbitan monopalmitate and sorbitan 20 EO tristearate. The emulsion obtained is transparent and stable on storage. It can comprise large amounts of oil while retaining good transparency and while having good cosmetic properties. The invention also relates to the use of the nanoemulsion according to the invention in the cosmetics and dermatological fields, in particular for moisturizing the skin and/or mucous membranes, as well as for treating the hair, and in the ophthalmological field, as an eye lotion for treating the eyes.
