  • Patent number: 5985302
    Abstract: Methods, compositions and a kit for deactivating spills or leaks of HIV infected blood or anticancer drugs by applying to the leak or spill an aqueous solution containing calcium hypochlorite or sodium hypochlorite as the active ingredient. In order to thicken the aqueous solution and thus keep it from spreading beyond its intended area of application, the solution of calcium hypochlorite contains methylcellulose. In addition to chemically deactivating the active anticancer drug, the solution of the invention also effectively decolorizes it, thus preventing permanent stains on any surface or fabric with which the anticancer drug comes into contact.
