Publication of the Final Screening Assessment for the Other Polymers Group. The Risk Management Approach for PHMB (CAS RNs 32289-58-01 and 27083-27-81) was also published for a 60-day public comment period. The related notice was published in the Canada Gazette, Part I: Vol. 157, No. 19.

October 3, 2020 Publication and start of 60-day public comment period on the Draft Screening Assessment for the Other Polymers Group and the Risk Management Scope for PHMB. The related notice was published in the Canada Gazette, Part I: Vol. 154, No. 40.


These substances were previously evaluated under the second phase of polymer rapid screening and identified as requiring further assessment due to potential human health risk.
