Consultation on fatty acid cluster and its associated end-use products, Proposed Re-evaluation Decision PRVD2025-05

Health Canada is consulting Canadians on the proposal to continue registration of products containing fatty acids, potassium salts of fatty acids, triethanolamine salts of fatty acids and ammonium salt of fatty acid and associated end-use products registered for sale and use in Canada, with proposed updates to standard label statements.

When the proposed label directions are followed, these products are shown to have acceptable value in providing a pest management solution, and potential risks to human health and the environment are considered to be acceptable.

Potassium salts of fatty acid products: Registered insecticides or herbicides for both commercial and/or domestic applications on: greenhouse, indoor and outdoor uses; seed production for several crops and indoor cannabis.

Products of triethanolamine salts of fatty acids: Registered as insecticides for commercial and/or domestic use on: greenhouse, indoor and outdoor ornamentals; and outdoor fruits and vegetables.

Products of fatty acids: Registered herbicides that manage several species of weeds around commercial and domestic buildings, around greenhouses, several outdoor areas, and around plants and gardens.

Products of ammonium salt of fatty acid: Registered as commercial and/or domestic herbicides used to manage weed species and liverworts around: greenhouse crops; interiorscapes; outdoor food crops; commercial indoor and outdoor cannabis and industrial hemp, outdoor areas and on and around structures, patios and walkways; and outdoor turf and gardens.

Currently registered products containing these active ingredients are listed in Appendix I of PRVD2025-05.
