Abstract

The process for the short-term preservation of rawhides and skins with an alkali metal chlorite solution which additionally also contains a compound of the formula 1 ##STR1## in which R denotes hydrogen or C.sub.1 -C.sub.12 -alkyl, Me denotes hydrogen or an alkali metal atom and n denotes 1 or 2. Because of their hydrotropic action, the addition of these compounds improves uniform penetration of the preservation solution into the hide.
