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. Des compositions liquides concentrées assouplissantes pour tissus, instables du fait d'une séparation de phase, sont stabilisées au moyen de polyesters solubles dans l'eau. Des compositions liquides stables comprenant divers électrolytes traitant les tissus sont également décrites. Des compositions comprenant des stabilisants à oxyde de téréphtalate-éthylène contenus dans les compositions assouplissantes pour tissus renferment divers agents chélatants tels que éthylènediamine disuccinate, diéthylènetriamine pentaacétate et divers aminophosphonates redonnent souplesse et couleurs aux tissus qui ont été exposés à des cations métalliques, notamment le cuivre ou le nickel. Des compositions comprenant des enzymes cellulase sont également décrites.
