Oxine is "inactive" stabilized chlorite. Until activated it is not or cannot become chlorine dioxide gas. No shipping Clo2 ever....ever...no exceptions. Now you can ship sodium chlorite (dry or liquid) (if you follow the regulations) but would need to "acidify" it or activate it at the other end. Most products require mixing part a and b on site following the recipe for exact ppm constants or other ways when using it for cleaning, deodorizing, water purification, and many other applications in a large or small chicken house. It definitely cleans up any bronchial problems with very small treatments. Did you know there is a simple recipe for converting your waste into bacteria free nitrogen rich liquid and dry fertilizer? Just find someone who knows about formulating clo2 and using it correctly. It's very powerful yet very save at small ppms. Thanks and I hope this helps.
