Composition comprising hyaluronic acid-based polyion complex and hydrophilic or lipophilic antioxidant

Abstract

The present invention relates to a composition comprising: (a) at least one complex 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 hydrophilic or lipophilic antioxidant; and (c) water, wherein the anionic polymer is selected from hyaluronic acid, salts thereof, and derivatives thereof, and the amphoteric polymer is selected from cationized hyaluronic acid and salts thereof. The composition according to the present invention can be transparent or translucent, or less sticky, and can provide long lasting antioxidative effects.
