Abstract
Concentrated liquid fabric softener compositions which are unstable due to phase separation are stabilized by means of water-soluble polyesters. Stable liquid compositions comprising various fabric treatment electrolytes are provided. Compositions comprising terephthalate-ethylene oxide stabilizers in fabric softener compositions comprising various chelators such as ethylenediamine disuccinate, diethylenetriamine pentaacetate and various aminophosphonates restore softness and dye colors to fabrics which have been exposed to metal cations, especially copper or nickel. Compositions comprising cellulase enzymes are also disclosed.
