<p>Compsn. contains (a) 5-75% alkaline agent which improves the detergency; (b) 0.5-30% wetting agent; and (c) 2-40% flocculating agent. Component (a) is sodium tripolyphosphate, or mixts. of sodium tripolyphosphate with an alkali which is potassium hydroxide, sodium sulphate or sodium carbonate; or trisodium phosphate, tetra sodium pyrophosphate, tetrapotassium pyrophosphate sodium hydroxide, nitrilotriacetic acid, sodium citrate, potassium citrate, or their mixts. Component (b) is an anionically modified ethoxylate with 4-18C chain length. Component (c) is polydiallyl-dimethyl, ammonium chloride with average molecular wt. 100,000-300,000; or polyacrylamide with average molecular wt. 2 x 106 15 x 106; or a copolymer of dimethyl-diallylammonium chloride and acrylamide with molecular wt. >1 x 106. The compsn. can be used in cleaning machines contg. a single reservoir for the treatment soln.; the used soln. can be recycled to this reservoir after filtration.</p> |
