Abstract: The present invention relates to a composition comprising: (a) at least one particle comprising at least one cationic polymer and at least one anionic polymer, at least one cationic polymer and at least one amphoteric polymer, at least one anionic polymer and at least one amphoteric polymer, or at least one amphoteric polymer, and at least one non-polymeric acid having two or more pKa values or salt(s) thereof or at least one non-polymeric base having two or more pKb values or salt(s) thereof; (b) at least one surfactant; and (c) water, wherein the anionic polymer is selected from hyaluronic acid and derivatives thereof, and the amphoteric polymer is selected from cationized hyaluronic acid and salts thereof. The composition according to the present invention can provide long lasting cosmetic effects and/or improved moisturizing texture based on hyaluronic acid or cationized hyaluronic acid.

Abstract: The present invention relates to a composition, preferably a cosmetic composition, comprising: (a) at least one oil; (b) at least one polyglyceryl fatty acid ester, preferably with a polyglyceryl moiety derived from 2 to 6 glycerins; (c) at least one compound selected from the group consisting of resorcinol and resorcinol derivatives; and (d) water. The composition according to the present invention can be in the form of a nano- or micro-emulsion, or can have a lamellar structure or a lamellar phase, with better transparency and stability.

Abstract: The present invention relates to a cosmetic composition in the form of a nano- or micro-emulsion, comprising: (a) at least one oil; (b) at least one polyglyceryl fatty acid ester, preferably with a polyglyceryl moiety derived from 3 to 6 glycerins, more preferably 5 or 6 glycerins; (c) at least one hydrotrope; and (d) water. The cosmetic composition according to the present invention has a dispersed phase which has a smaller diameter due to a combination of the (b) polyglyceryl fatty acid ester and the (c) hydrotrope. Therefore, the cosmetic composition can be in the form of a nano- or micro-emulsion with transparent or slightly translucent.
