Abstract
Abstract Liquid formulations for use in treating fabrics deposit a material providing a perceivable effect. The effect producing material is a component, in admixture with an organic matrix material and a cationic material, of a dispersed phase in an aqueous medium. The cationic material causes deposition of the dispersed phase onto a fabric allowing the effect producing material to act on the fabric surface. Optionally a fabric conditioning material is present in the aqueous phase.
