Abstract

Soil-collecting detergency enhancers for detergent solutions comprising a substantially water-insoluble polyfunctional quaternary ammonium compound or a water-soluble polyfunctional quaternary ammonium compound fixed to a water-insoluble solid carrier. The detergency enhancers may be used in the cleaning of soiled articles, particularly those soiled with pigments, in aqueous detergent solutions such as for washing fabrics.
