Hypomide was a stable formulation of hypochlorous acid used as a hand and surface sanitizer in both the hospital and home environment. Before the advent of Hypomide, hypochlorous acid had limited use in the healthcare environment because its instability necessitated in-situ production by electrolysis involving special equipment. Nevertheless, its potency as an antimicrobial agent was recognised and hypochlorous acid is often relied upon by dentists, for example, to clean their tools and instruments. It is no longer commercially available.
Because hypochlorous acid kills microorganisms at very low concentrations (e.g. it is bactericidal at between 0.1 and 10 parts per million) it can be presented at less than 1% solution in saline and yet remain highly effective. It provides a 7 log10 reduction in a wide range of commonly encountered microorganisms, including gram positive and gram negative bacteria (even multi-resistant strains such as MRSA), fungi and viruses. A 7 log10 reduction equates to 99.99999% kill rate: 100 times greater than the required pass rate on the BS:EN 1276 standard test for sanitizers and disinfectants. Even against difficult-to-treat spores, such as the dangerous Clostridium difficile, Hypomide achieves a 5 log10 kill rate.
