Consultation on 1,3-bis(hydroxymethyl)-5,5-dimethylhydantoin and hydroxymethyl-5,5-dimethylhydantoin and Associated End-use Products, Proposed Re-evaluation Decision PRVD2022-10

Health Canada is consulting Canadians on the proposal to continue registration of products containing 1,3-bis(hydroxymethyl)-5,5-dimethylhydantoin (DMY) and hydroxymethyl-5,5-dimethylhydantoin (MMY) registered for sale and use in Canada. As a result of the re-evaluation of DMY and MMY, Health Canada proposes further risk-reduction measures in addition to those already identified on product labels.

DMY and MMY are antimicrobial material preservatives used in a wide variety of products such as liquid detergents, soft soaps, room deodorizers and air fresheners, water-based surfactants, polymer emulsions, protective and decorative coatings, water-based gels for household and industrial products, textiles, water-based adhesives, latex for paper and coatings, and water-based inks. DMY and MMY are of value in aiding in the prevention and control of bacterial and fungal contamination of aqueous-based materials. Such contaminations can lead to product failures of function or discolorations/unpleasant odours that will make the product unusable.

For a full list of products containing DMY and MMY, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.

For more information on the proposed decision open the “Proposed Re-evaluation Decision”.
