The surface modifying composition may comprise a blend of an ionic polyurethane and a second polymer, e.g. another polyurethane or an acrylic polymer wherein the particle size of the second polymer are greater than that of the base ionic polyurethane. The use of blends enables donning of the glove to be effected without the aid of donning powder such as starch or talc.
