Detergent composition comprising an anionic or amphoteric surface active

Abstract

A detergent composition is disclosed, which comprises (A) 0.1 to 40% by weight of at least one kind of anionic or amphoteric surface active agents and (B) 0.05 to 4% by weight of at least one kind of quaternary ammonium salts represented by the following formula (I) or (II): ##STR1## wherein R.sub.1 represents a mixture of (a) a branched alkyl group represented by ##STR2## and (b) a linear alkyl group represented by CH.sub.3 --(CH.sub.2).sub.n -- wherein R.sub.7 represents a methyl or ethyl group, m is an integer to make the carbon atom content of the branched alkyl group to 8 to 16, and n is an integer of 7 to 15), with a ratio (a)/(a)+(b) being 0.1 to 1, R.sub.2 and R.sub.3 independently represent a benzyl group, an alkyl group having 1 to 3 carbon atoms, or a hydroxyalkyl group having 1 to 3 carbon atoms, R.sub.4 and R.sub.5 independently represent an alkyl group having 2 to 12 carbon atoms, R.sub.6 represents a group ##STR3## or an alkyl group having 1 to 3 carbon atoms, and X.sup.- represents a halogen ion or an organic anion. The detergent composition provides a shampoo with superb hair conditioning effects; softness and smoothness after washing, less sticky feeling, easy passage of comb through the hair, less hard or rough feeling as well as easy hair-set performance after drying. The detergent composition also provides a liquid detergent suitable for washing cloths made of wool or made of fine denier fibers.
