Abstract: The additive contains a highly swelling, water-insoluble, highly polymeric substance as gel former which is coated with or dispersed in a water-soluble release agent which does not cause the gel-former particles to swell. The release agent is preferably a polyethylene glycol and is employed in an amount of from 10 to 100% by weight, based on the amount of gel former.
