1. An aqueous fabric treatment composition comprising (I) one or more cationic acrylic polymer emulsions/dispersions and (II) a water soluble or dispersible silica gel, alone or in combination with a zeolite, wherein the cationic acrylic polymer is self-cross-linking or, if not, the composition further comprises (III) a suitable cross-linking agent for the cationic acrylic polymer, each of (I) and (II) being or including solid and/or solid forming components, wherein the weight ratio of the solid/solid forming components of the composition (I:II) is from 1:25 to 25:1, based on cationic acrylic polymer emulsions/dispersions having from 40 to 55% solids content.
