摘要：A granular, alkaline cleaning additive, free from phosphate, contains (a) 20-40 wt.% of the Na salt of a (meth)acrylic acid (co)polymer, (b) 8-25% of Na silicate with Na20:Si02 = 1:1-3.4, (c) 15-50% of Na2CO3 and/or Na2SO4 (calc. as anhydrous), 0-15% of aminopolycarboxylate and/or polyphosphonate sequestering agent, and (e) 5-15% of water. The amts. are (a) 23-35 wt.%, (b) 12-20%, (c) 18-45%, pref. of Na2CO3, (d) 0-12% and (e) 8-12%. The average grain size is 0.2-1.2 mm, with not more than 2 wt.% of grains of below 0.1 mm, and not more than 20% above 2 mm. Esp., at least 80% (at least 90%) of the grains are 0.2-1.6 mm, with not more than 3% (not more than 1%) of 0.1-0.05 mm, and not more than 20% (not more than 10%) of 1.6-2.4 mm. USE/ADVANTAGE - The mixt. is used as component in washing, cleaning and watersoftening agents (claimed). Appln. is esp. in dishwaster rinses. The granulate is free-flowing, and is stable even in a moist atmos.
