<p>In a low foam, liq. or powder machine washing compsn., the surfactant component contains 5-30% of alkylpolyglycoside, 5-30% of alkanol ether carboxylate, 5-30% of soap, and 0-3% of other surfactants. The alkylpolyglycoside is R-O-Zn and is esp. a fatty alcohol polyglucoside. The alkanol ether carboxylate is (R'-O(CH2CH2-O)xCH2COO)mMm+ or ((R''-O(CH2CH2-O)y)2CHCOO)zNz+, and the soap is R'''COOP. R = 10-18C (un)branched, (un)satd. alkyl; Zn = polyglycosyl radical with n = 1-3 hexose or pentose units; n esp. = 1.1-2; R'' = 8-22C (un)branched alkyl; x, y = 1-40; esp. x = 3-20; z = 1 or 2; m = 1 or 2 (1); M, N = H, alkali(ne earth), NH4 or alkanolammonium, pref. Na, K, NH4 or alkanolammonium; R' = 8-22C (10-18C) (un)satd., (un)branched alkyl; R''' = 8-22C satd. and/or unsatd. alkyl; P = H, alkali, NH4 or alkanolammonium. The concn. of the tenside component is 0.3-20 g/l. The compsn. may contain builders, bleaches, suspension agents, enzymes, stabilisers, greying inhibitors, corrosion inhibitors, optical brighteners, dyes, perfume oils and opt. other non-surfactant components.</p> |
