Re-evaluation Decision

Potassium peroxymonosulfate is a commercial surface and equipment disinfectant used to control viruses, bacteria and fungi. Registered products containing potassium peroxymonosulfate are listed in Appendix I.

Under the Pest Control Products Act, all registered pesticides must be regularly re-evaluated by Health Canada’s Pest Management Regulatory Agency (PMRA) to make sure they continue to meet the most recent health and environmental safety standards and continue to have value. After a re-evaluation of potassium peroxymonosulfate, the PMRA is granting continued registration of products containing potassium peroxymonosulfate for sale and use in Canada.

An evaluation of available scientific information found that products containing potassium peroxymonosulfate do not present unacceptable risks to human health or the environment when used according to the label directions. No additional mitigation measures or label updates are required. No additional data are required at this time.

This re-evaluation decisionFootnote 1 was proposed in the consultation document, Proposed Re-evaluation Decision PRVD2017-02, Potassium Peroxymonosulfate. No comments were received during the consultation process. Therefore, this decision is consistent with the proposed re-evaluation decision stated in PRVD2017-02.

A reference list for all data used as the basis for the re-evaluation decision is also included in PRVD2017-02.
