    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.

    Abstract: The vesicles are prepared from a lipid phase containing a mixture of amphiphilic non-ionic lipids consisting of a mixture of esters of at least one polyol chosen from the group composed of polyethylene glycol containing from 1 to 60 ethylene oxide units, sorbitan, sorbitan bearing 2 to 60 ethylene oxide units, glycerol bearing 2 to 30 ethylene oxide units, polyglycerols containing 2 to 15 glycerol units, sucroses, and glucoses bearing 2 to 30 ethylene oxide units, and of at least one fatty acid containing a saturated or unsaturated, linear or branched C5-C17 alkyl chain, the number of alkyl chains per polyol group being between 1 and 10, the mixture being stabilised with amphiphilic ionic lipid(s) chosen from the group composed of those which endow the dispersion with a pH of between 5.5 and 7.5.
