Abstract

The invention relates to an aqueous preparation for shrinkproofing wool, which contains, as active ingredient, organopolysiloxanes of a particular structure with mercaptoalkyl or mercaptoaryl radicals and hydrogen atoms. The preparation is storage-stable and causes no yellowing in naturally colored or white wool. The hand of the wool is not disadvantageously affected.
