Beschreibung
Zusammenfassung:	The present invention relates to a method of treating a mineral or textile porous substrate to inhibit or reduce microbial growth in that porous substrate comprising the step of applying an anti-microbial composition to the porous substrate. Suitable anti-microbial compositions comprise one or more quaternary ammonium compounds selected from aminoalkyl(meth)acrylate polymer quats and alkoxylated quats, wherein the or each quaternary ammonium compound comprises an aliphatic C8 to C16 alkyl group, and at least one solvent selected from water and organic solvents. Suitably the anti-microbial composition does not comprise a binder polymer or resin and the quaternary ammonium compound penetrates the porous substrate to inhibit or reduce microbial growth in the porous substrate.
