Our active ingredient is a proprietary blend of Chitosan and CLO2. Chitosan has been studied and reviewed by numerous Departments and Agencies in the USA, as well as a growing list of equivalent agencies in other nations. CLO2 is a recognized safe disinfectant used for the purification of drinking water.

Below, you will find an assortment of quotations and links to documents detailing the approvals, studies, and scholarly articles detailing the Relative Safety & Efficacy of this wonder of nature.

Significant Quotes:

  • “By adding this naturally-occurring substance to this list, the agency can save taxpayers and stakeholders time and money through waived Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) registration requirements for certain products containing Chitosan.”
  • “Chitosan is a naturally occurring substance found in the cell walls of all crustaceans, most fungi, and the exoskeletons of most insects. It is currently registered with EPA as a fungicide, antimicrobial agent, and plant growth regulator that boosts the ability of plants to defend against fungal infections.”
  • “After reviewing the latest available science, consulting with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel , and ensuring that all criteria are met, EPA is now proposing to add Chitosan to its list of active ingredients eligible for EPA’s minimum risk pesticide exemption. EPA estimates the cost savings of this action could be up to $116,000 initially and about $3,400 per year thereafter.”
  • “[The] EPA created the exemption for minimum risk pesticides in 1996 to reduce the cost and regulatory burdens on businesses and the public for pesticides posing little or no risk to human health and the environment.”
