US 5,580,481 A · Aqueous fabric softener composition, novel quaternary ammonium salt, and process for the preparation of said salt

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.
