Abstract
Abstract Concentrated fabric softening/static control compositions, for use in the rinse cycle of the laundering operation, are disclosed. These compositions include a water-insoluble cationic softener, a long-chain hydrocarbon, such as paraffin, and specific mono-long chain amine or amine-derived compounds. The use of these amine compounds provides compositions, exhibiting excellent softening and static control performance, which are stable during long periods of storage and which are easily processed due to their viscosity characteristics. A method for preparing these compositions is also disclosed.
