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.
A method of imparting odor control and inhibition to fabrics and textiles said method comprising applying to the fabric or textile an odor controlling effective amount of an aqueous fabric treatment composition comprising (1) 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.
