Toxic substances list: 4 new fluorotelomer-based substances

The four new fluorotelomer-based subtances 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.
