Abstract
Abstract Concentrated textile treatment compositions suitable for use in the rinse cycle of a textile laundering operation containing from 12% to 25% of an active mixture comprising a water-insoluble quaternary ammonium fabric softener, a water-soluble alkoxylated ammonium surfactant and a fatty acid ester of a polyhydric alcohol. The compositions are stable dispersions displaying excellent viscosity characteristics at both low and high temperature over prolonged periods of storage.
