<p>The need for active washing agents for washing and cleaning in acqueous baths is reduced by the use of existing polyfunctional, quaternary ammonium compounds which are insoluble or are immobilized on insoluble solid carriers, whilst simultaneously maintaining the same washing and cleaning qualities. The active washing agents which can be economised are builders, tensides, anti-redeposition agents, washing alkalis or mixtures thereof. Solid carriers are above all fine-particle materials with a high specific surface area and high absorption capacity for oleophilic dirt.</p> |
