[Which galenic bases are in use nowadays for skin treatment?]

Different base types are necessary for dermatological preparations. The dominating part is played today and probably will also be played in the future by the hydrocarbon gels and the derivated cream systems. Possible interferences of the ingredients with the base components have to be watched by the dispensing of medical preparations for dermatological therapy. In regard to an optimal distribution of the ingredients solubility of the ingredients in the bases are important. Specific preservatives can be omitted if ethanol is added in concentrations of at least 15 per cent. There is a tendency to use mainly indifferent components.
