    Abstract: Nanocapsules comprising the following components are new: (a) a lipid core comprising a lipophilic active ingredient (I); and (b) a water-insoluble shell comprising a water-dispersible anionic polymer (II) selected from polyesters, poly(ester amides), polyurethanes, vinyl copolymers, shellac, sandarac gum and dammars. Independent claims are also included for the following: (1) a cosmetic or dermatological composition containing the nanocapsules in a carrier; (2) a process for producing the nanocapsules, comprising: (i) dissolving a lipid phase comprising (I) and optionally a coating agent in a nontoxic organic solvent having a lower boiling point than water; (ii) preparing an aqueous dispersion of (II); (iii) adding a hydrophilic surfactant to the dispersion; (iv) combining the organic phase of (i) with the organic phase of (iii); and (v) evaporating the organic solvent and optionally part of the aqueous phase; (3) a process for producing the nanocapsules, comprising: (i) dissolving (II), a lipid phase comprising (I) and optionally a coating agent in a water-miscible organic solvent; (ii) pouring the solution into an aqueous surfactant solution; and (iii) evaporating the organic solvent and optionally part of the aqueous phase.

    Abstract: 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 mixed esters of fatty acids or alcohols, carboxylic acid and glycerol; 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 -18 x 10 Pa.

    Abstract: Composition comprises an aqueous dispersion of lipid bubbles encapsulating a UV filter with a (partly) neutralised acid function. The composition is characterised in that the bubbles have a lipid membrane formed from (A) a nonionic amphiphilic lipid; (B) an ionic amphiphilic hydrocarbon lipid with iodine index below 10; and (C) a completely neutralised amphiphilic ionic lipid.
