Abstract

Abstract An antistatic fabric softening composition comprising the following four ingredients (I) to (IV): I. 4 - 10% by weight of a quaternary ammonium salt having two long-chain alkyl groups having 16 to 22 carbon atoms; II. 0.5 - 3.0% by weight of at least one antistatic agent selected from compounds expressed by the following formula WHEREIN R1 is an alkyl group having 14 to 22 carbon atoms, R2 stands for an alkyl group having 1 to 3 carbon atoms of a benzyl group, X designates Cl, Br or C2H5SO4, and the sum of m and n is from 5 to 20, AND COMPOUNDS EXPRESSED BY THE FOLLOWING FORMULA WHEREIN R3 is an alkyl group having 16 to 22 carbon atoms, R4 and R5 stand independently for an alkyl group having 1 to 3 carbon atoms, and p is a number of from 1 to 4; III. 0.5 - 2.0% by weight of at least one non-ionic surfactant containing an alkyl group having 8 to 18 carbon atoms and having 40 - 90 moles of ethylene oxide units; and IV. 2 - 10% by weight of at least one additive selected from the group consisting of alcohols having 1 to 3 carbon atoms, glycols having 2 to 3 carbon atoms, glycerol, sorbitol and urea.
