Nanoemulsion based on ethoxylated fatty ethers or ethoxylated fatty esters and uses thereof in the fields of cosmetics, dermatology and/or ophthalmology

摘要

A nanoemulsion comprising a dispersed lipid phase in an aqueous phase with lipid globules having an average size of less than 100 nm contains: (1) a surfactant such as ethoxylated fatty esters or ethers; and (2) at least one oil with a molecular weight of more than 400 and at a lipid phase/surfactant weight ratio of 2-10. Independent claims are also included for: (1) a topical composition comprising the above described composition; (2) an ophthalmic support comprising the above described composition; (3) a pharmaceutical composition comprising the above described composition; (4) a cosmetic method for the care and/or hydration of the skin, mucosa and/or scalp by applying the above described composition; and (5) the preparation of the composition by mixing an aqueous phase and a lipid phase at 10-80 degrees C and homogenizing the mixture at 6 x 10<7>-18 x 10<7> Pa.
