Our HCLO Patent & Technology
Despite hypochlorous acid (HCLO) having all the characteristics of being a superior disinfectant for bacteria and viruses, it has not been so popular for general use, because it was difficult to produce, unstable, and hard to store.
Our patented technology has resolved all the known drawbacks of HCLO. Our process can produce pure and stable HCLO water, safely, easily, with prolonged storage life. Furthermore, the ingredients are natural.
Our technology is registered in Japan on December 2, 2021 under Patent No. 6986797. We are currently patent pending with the rest of the World, and are protected under International Patent Cooperation Treaty.
