Toxic substances list: 4 new fluorotelomer-based substances

The four new fluorotelomer-based substances discussed below are:

  1. Hexane, 1,6-diisocyanato-, homopolymer, reaction products with alpha-fluoro-omega-2-hydroxyethyl-poly(difluoro- methylene), C16-20-branched alcohols and 1-octadecanol
  2. 2-propenoic acid, 2-methyl-, hexadecyl ester, polymers with 2-hydroxyethyl methacrylate, gamma-omega-perfluoro-C10-16-alkyl acrylate and stearyl methacrylate
  3. 2-propenoic acid, 2-methyl-, 2-methylpropyl ester, polymer with butyl 2-propenoateand 2,5 furandione, gamma-omega-perfluoro-C8-14-alkyl esters, tert-Bu benzenecarboperoxoate-initiated
  4. 2-propen-1-ol, reaction products with pentafluoroiodoethane tetrafluoroethylene telomer,dehydroiodinated, reaction products with epichlorohydrin and triethylenetetramine

Fluorotelomer-based substances are commonly used in water, oil, soil and grease repellents for fabric, leather, rugs and carpets, as well as stone and tile; in sizing agents (to resist the spreading and penetration of liquids) for packaging and paper products; and in levelling agents (to provide an even surface) for coatings.

The assessment of the new fluorotelomer-based substances concluded that they could be sources of long-chain perfluorocarboxylic acids (LC-PFCAs). The Prohibition of Certain Toxic Substances Regulations, 2012 prohibit the manufacture, use, sale, offer for sale and import of the four new fluorotelomer-based substances, and products that contain them, with a limited number of exemptions

On October 13, 2018, a Notice of intent to amend the Prohibition of Certain Toxic Substances Regulations, 2012 was published in Canada Gazette, Part I for a 30-day public comment period that ended on November 12, 2018.

On December 20, 2018, a consultation document describing the proposed amendments to the Prohibition of Certain Toxic Substances Regulations, 2012 was published on the Canadian Environmental Protection Act Registry for a 60-day public comment period. The proposed amendments would seek to further restrict the manufacture, use, sale, offer for sale and import of certain toxic substances including the four new fluorotelomer-based substances as precursors to LC-PFCAs.

Comments and information received in response to the notice of intent and the consultation document will be considered in the development of proposed regulations to amend the Prohibition of Certain Toxic Substances Regulations, 2012 targeted for publication in winter 2020.
