<p>Textile softeners consist of condensates (A) of (a) 1-1.5 mol. fatty acid or fatty acid ester of formula R-COOX (I) (where R is 11-21C aliphatic gp.; and X is H, Me or Et) with (b) 1 mol. alkyl propylene diamine oxyalkylate of formula (II): R1-N-(CH2)3-N (CH2CHR2O)xH (CH2CHR2O)zH (CH2-CHR2-O)zH (where R1 is 12-22C aliphatic gp.; R2 is H or Me; x, y and z are 0 or 1; and x + y + z = 1 or 2). Textile softener compsns. are used aq. solns. or dispersions contg. 1-15 wt. % (A) or as liquid, aq. concentrates contg. 20-35 wt. % (A). The compsns. are added esp. to last rinsing cycle of washing machines, to impart a soft hand to textiles of cellulose, wool, cellulose acetate and triacetate, polyamide, polyacrylonitrile, polyester and polypropylene. They are partic. useful for after-treatment of towelling and underwater. (A) are easily dissolved or dispersed in water. A condensate of 1 mol. (345g) adduct of 1 mol. ethylene oxide to 1 mol. stearyl propylene diamine and 1 mol. (264 g) stearic acid formed a dilutable aq. dispersion, useful as rinsing additive after washing towelling.</p> |
