ABSTRACT OF THE DISCLOSURE The washing additive contains a mixture of detergent ingredients embedded in a film of organic, flexible, film-forming water-soluble polymers. The washing additive contains at least two active substan- ces which may be a nonionic surface-active compound, an activator for per compounds and various nitrogen- containing compounds. To avoid gelation, the washing additive best contains an antigel agent, preferably a poyhydric alcohol containing from 2 to 4 carbon atoms, optionally in admixture with certain fatty alcohol ethoxylates. The nitrogen-containing compounds may be quatenary ammonium compounds containing a long-chain radical, adducts of ethylene oxide with a primary fatty amine or salts of certain aminocarboxylic acids. The film-forming polymer in which the active substances are embedded, is preferably polyvinyl alcohol having a degree of hydrolysis of from 70 to 90% and a molecular weight in the range from 10,000 to 100,000. In com- bination with standard detergents, the washing additive boosts the removal of fatty/oily, pigment-containing and bleachable stains.
