PIGMENTED CHITOSAN CAPSULES |
摘要 |
Pigmented capsules containing chitosan as a constituent of the wall material are produced by preparing a dispersion, which consists of a pigment and, optionally, of a lipid constituent, in an aqueous solution of a chitosan salt. Said dispersion is introduced into the aqueous solution of a precipitating agent or cross-linking agent for the chitosan which results in the formation of capsules preferably having a diameter ranging from 0.1 to 10 mm. The capsules are suitable as a constituent used for producing aesthetic effects and as a support for cosmetic or dermatological active substances in aqueous preparations. |
