Abstract
To provide an aqueous fabric softener composition, which is excellent in softening performance, elasticity and storage stability, and a quaternary ammonium salt which is useful as a softening base of this composition and nondetrimental to the natural environment because of its excellent biodegradability, and a process for the preparation of this salt. The aqueous fabric softener composition of the present invention comprises from 8 to 40% by weight of a quaternary ammonium salt represented by the following formula (I), a quaternary ammonium salt represented by the following formula (II) or a mixture thereof, and water: ##STR1## wherein R.sup.1 and R.sup.2 represent each a C.sub.1-4 alkyl group, etc.; R.sup.3 and R.sup.4 represent each a C.sub.7-35 alkyl group, etc.; and X.sup.- represents an anion group; and ##STR2## wherein R.sup.5 and R.sup.6 represent each a C.sub.1-4 group, etc.; R.sup.7 and R.sup.8 represent each a C.sub.1-5 alkylene group, etc.; R.sup.9 and R.sup.10 represent each a C.sub.8-36 alkyl group, etc.; Q represents a C.sub.2-6 alkylene group; n is from 0 to 10; and X.sup.- represents an anion group.
