A METHOD OF STABILIZING PACKAGED ACTIVE CHLORINE-CONTAINING SOLUTIONS AGAINST LIGHT-INDUCED DEGRADATION EMPLOYING STABILIZED HYPOCHLORITE SOLUTIONS IN COMBINATION WITH A CONTAINER
摘要
A method of reducing light-induced degradation of stabilized hypochlorite solutions when packaged in a container which is in whole or in part transparent or semi-transparent is described. The method involves incorporating at least one UV blocker in at least the transparent or semi-transparent portion of the container or incorporating a UV blocker in a wrap which overlays at least the transparent or semi-transparent portion of the container. The container or wrap is composed of plastic such as polyethylene terephthalate, polyethylene, polypropylene, polystyrene or polyvinyl chloride. The UV blocker is present in a concentration of about 0.01-2.0 % by weight and serves to provide reduction in transmission of UV light in a wavelength range of from about 300-400 nm. The stabilized hypochlorite solution is a buffered aqueous combination of mono-N-chlorosulfamate and di-N-chlorosulfamate salts. The invention is also directed to the stabilized hypochlorite solution in combination with a container for the solution, the container being in whole or in part transparent or semi-transparent and having at least one UV blocker present in relation thereto.
