Colored capsules with chitosan as a component of the wall material, which include an emulsion of a lipid component in water and the conversion of which consists predominantly of a chitosan-dye complex, are produced by using a lipid component, an emulsifier and an aqueous solution of a chitosan salt produces an emulsion of the oil-in-water type and introduces it into the aqueous solution of an anionic dye, which causes a chitosan-dye complex to be filled out, so that capsules form. The capsules are suitable as components for producing aesthetic effects and as carriers for cosmetic and dermatological active ingredients in aqueous preparations. |
