a detergent composition particularly useful in aqueous solutions for cleaning soiled surfaces . the formulation which may be in either dry or concentrate form , includes alkaline builders , wetting agents , and a flocculant , and may in certain instances , include a floatation agent . as an alkaline builder , sodium tripolyphosphate is normally preferred , while others such as mixtures of sodium tripolyphosphate with sodium sulphate or potassium hydroxide and soda ash may also be successfully utilized . the formulation is preferably applied to the surface as an aqueous solution in relatively heavy or thick layers , with agitation to permit the removed soilage to create flocs , and with the flocculated soilage being floated away from contact with the surface for facilitating removal .
