Viscous, gel-like ester mixtures of reaction products of fatty acid polyol partial esters and gamma-glycidoxypropyltrialkoxysilanes, which can contain, if desired, dicarboxylic acids as additional reaction components, and methods for their preparation are disclosed. The ester mixtures are especially provided as additives for oily liquids for the preparation of gels or for increasing viscosity. Also, spreadable preparations are disclosed, which are produced from a component of oily consistency and, preferably, an active agent contained therein, which, because they contain the new ester mixtures, consisting of products of the reaction of partial esters of polyols of the aliphatic monocarboxylic acids and, in some cases, the aliphatic dicarboxylic acids, with gamma-glycidoxypropyltrialkoxysilanes of high ability to adhere to the skin, are difficult to wash from the skin and make the skin difficult to wet. |
