Abstract (en)
Use of a surfactant (Q) comprising nitrogen containing compound (I) or alkane oxy compound (IV), in combination with an ethoxylated fatty alcohol compound (V), for improving the washability of the detergents at = 30[deg] C, preferably 20[deg] C, is claimed. Use of a surfactant (Q) comprising nitrogen containing compound (I) of formula ((R 1>CO-N(R 2>)-(A)-N +>(R 3>)(R 4>)-R 5>)(X ->)) (II) or ((R 6>-N(CH 2-CH 2-O) nH)-R 7>) (III) or alkane oxy compound of formula (R7a-(CH 2-CH 2-O) x(CH 2-CHCH 3-O) yH) (IV), in combination with an ethoxylated fatty alcohol compound of formula (R 8>-(CH 2-CH 2-O) r-H) (V), for improving the washability of the detergents at = 30[deg] C, preferably 20[deg] C, is claimed. R 1>optionally saturated, ethoxylated 16-22C-hydroxyacyl residue with 1-50 ethylene oxide units; A : 1-6C-alkyl; R 2>-R 4>1-4C-alkyl or H; R 5>an alkyl- or benzyl- residue; X : halo, alkyl sulfate or alkyl phosphate; R 6>optionally saturated 8-24C-alkyl; R 7>(CH 2CH 2-O) mH or optionally saturated 8-24C-alkyl; R7a, R 8>optionally saturated 6-22C-alkyl; and n, m, x, y, r : 1-10. Independent claims are included for: (1) a surfactant mixture comprising (Q) and (V), where the weight ratio of (Q) and (V) is 4:1-1:4, preferably 1:1; and (2) a detergent comprising 0.1-25 wt.% of the surfactant mixture.
