Abstract
Leather products that are well lubricated, impermeable and water-repellent are produced by impregnating tanned hides or skins under alkaline conditions with an aqueous emulsion of a mixture of alkyl or alkenyl carboxylic acids or anhydrides containing at least 16 carbon atoms, and in particular polyisobutenyl succinic acid or its anhydride containing at least 30 carbon atoms, and fatty acids in specified proportions followed by retaining with basic solutions or with the emulsion which is also covered may additionally contain fatty acids.
