Abstract

The present invention relates to a process for the production of derivatives of natural fats and oils that is characterized in that the fats that are solid at room temperature or which contain solid fractions, mixtures of these with free fatty acids, mono- and/or diglycerides are oxyalkylated at elevated temperatures in the presence of basic catalysts having at least one 1,2-epoxide and the conversion products so obtained, optionally, after epoxidization are sulphonated in a manner known per se. The products are particularly suitable for use as leather dubbing agents.
