Softening agent for woven fabrics

Claim 1

A softening agent for woven fabrics consisting essentially of A. from 3 to 20 weight percent of a quaternary ammonium salt having the formula ##STR3## wherein R 1 and R 2 each is alkyl having 12 to 20 carbon atoms or β-hydroxyalkyl having 14 to 22 carbon atoms; R 3 and R 4 each is alkyl or hydroxyalkyl having 1 to 3 carbon atoms, benzyl or --(C 2 H 4 O) n H, wherein n is an integer of from one to 3; and X is halogen or alkyl sulfate in which alkyl has from one to 3 carbon atoms; B. from 0.2 to 5 weight percent of polyoxyethyleneoleyl ether containing an average of from 8 to 200 moles of ethylene oxide; C. from 0.5 to 10 weight percent of urea, and D. from 0.08 to 2 weight percent of a water-soluble ammonium salt selected from the group consisting of the ammonia, monoethanolamine, diethanolamine and triethanolamine salts of mineral acids and carboxylic acids having one to 3 carbon atoms, and E. and the balance consists essentially of water, with the proviso that the weight ratios of A, B, C and D are as follows: B/a = 0.06 to 0.7 C/a = 0.1 to 1.3, and D/a = 0.025 to 0.17.
