Abstract

Abstract An antistatic softening composition, comprising 4-10 percent by weight of a quaternary ammonium salt of general formula (I): wherein R1 and R2 each represent an alkyl group of C14-C22, R3 and R4 each represent an alkyl group of C1-C3, benzyl group or (C2H4O)nH (n 1 - 3) and X represents Cl, Br or C2H5SO4, 0.1-5 percent by weight of an ethenoxy quaternary ammonium salt of general formula (II): wherein R5 represents an alkyl group of C10-C22, R6 represents an alkyl group of C1-C3 or benzyl group, X represents Cl, Br or C2H5SO4 and m and n each represent an integer of more than 1 inclusive, with the proviso that m +. n is 20-100, and 0.5-15 percent by weight of one or more additives selected from the group consisting of alcohols of lower than C3 inclusive, glycols, glycerol, sorbitol and urea.
