The disclosure relates to polymeric systems for stabilizing, storing and delivering hypohalide salts. One system consists of material coated with two layers: one prepared from polyethylene glycol epoxide and melamine solution and second prepared from inorganic hypohalide salt solution. The material can be fabric, cotton, bamboo, cellulosic materials, and blend of cellulosic and synthetic fibres. Antimicrobial materials comprising this system are also described. Another system consists of material containing pre-formed spaces coated with water-polyethylene glycol solution of hypohalide salt and encapsulated by film forming polymer. Hypohalide salts within both systems are storage stable for at least three months. Particularly disclosed is a method of delivering storage stable hypohalide salts, the method comprising steps of: contacting a material with a first aqueous solution including polyethylene glycol epoxide and melamine;drying the first aqueous solution on the material; contacting the material with a second aqueous solution including a hypo halide salt; and drying the second aqueous solution on the material; wherein the hypohalide salts in the material are stable for at least three months when exposed to atmosphere. |
