Abstract
Abstract A comelted, granular fabric softening composition which is water dispersible in the cold water rinse of a washing machine, comprising about 60% to about 85% of a di-(long chain) quaternary ammonium salt and about 15% to about 40% of a mono- (long chain) quaternary ammonium salt having from 10 to 14 carbon atoms in its single long chain. The fabric softening composition may also contain up to about 25% of optional ingredients. In one embodiment of the invention the fabric softening agent is adapted to be placed within a water-permeable envelope. The envelope can be inserted into a washing machine during a laundering operation to provide fabric softening benefits to the clothes being laundered.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A comelted, solid, granular fabric softening composition comprising: A. 60% to 85% of a first compound having the formula: ##STR9## wherein R 1 and R 2 are lower alkyl moieties, R 3 and R 4 are each higher alkyl or alkenyl moieties having from about 14 to about 22 carbon atoms, and X is an anion; and B. 15% to 40% of a second compound having the formula: ##STR10## wherein R 5 , R 6 and R 7 are each lower alkyl moieties, R 8 is an alkyl or alkenyl moiety having from about 10 to about 14 carbon atoms, and Y is an anion; wherein the softening effect of said solid, granular composition is improved with, improved rinse water dispersibility.
Claim 2
Dependent Claim
