Documented Uses

3(2H)-Isothiazolone, 2-methyl-, hydrochloride (1:1): ACTIVE
Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection.
Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)
