J. Soc. Cosmet. Chem., 25, 423-435 (August 1974) Auswirkungen grenzfi•ichenaktiver Substanzen auf LOslichkeit, chemische Stabilitat und Verftigbar- keit cutan applizierter Wirkstoffe BERNHARD C. LIPPOLD * Vortrag anl•ifilich der Vortrags- und Diskussionstagung der Gesellschafi Deutscher Kosmetik-Chemiker e. V., Baden-Baden, Bundesrepublik Deutschland, 14.--16. Miirz 1974. Synopsis--Effects of Surface-Active Materials on the Solubility, Chemical Stability, and Availability of Cutaneous Applied Agents.--SURFACE-ACTIVE MATERIALS in so- lution--especially above their CMC-- influence cutaneously applied agents differently. The presence of MICELLES generally improves SOLUBILITY but can effect responses of IN- TOLERANCE. The rates of reactions of HYDROLYTIC and OXIDATIVE PROCESSES are altered by MICELLE FORMERS. In order to predict STABILIZATION, exact know- ledge of the DECOMPOSITION REACTIONS is required. With regard to AVAILABILITY OF THE AGENT, the presence of surface-active materials has far-reaching consequences. Reduction of availability i.e. LOWERED ACTIVITY, depends greatly on the physico- chemical properties of the agents. The regularities pertaining to micellar solutions ,are de- finitely applicable to other systems. * Dr. Bernhard C.
