CAS Registry Number 6731-36-8

What is it?

  • DBTMC is a man-made chemical powder used by industry in the manufacture of rubber and plastics.

How is it used?

  • When it is heated, DBTMC produces chemicals that can react to make rubber and plastics.
  • Based on the most recent data, DBTMC is not manufactured in Canada.  It is, however, used in the production of many common items containing rubber and plastics that are currently in commerce in this country.

Why Did the Government of Canada Assess It?

  • The Government of Canada had a concern that DBTMC may have been "toxic" to the environment as defined under the Canadian Environmental Protection Act, 1999.
  • DBTMC can get into the environment when waste materials from making rubber and plastics are washed down the drain or when containers that held DBTMC are rinsed.
  • DBTMC can build up in the bodies of animals, but it does not stay in the environment for a long time, and small amounts of DBTMC are not likely to harm animals or plants that live in the water.
  • DBTMC was assessed by Government of Canada scientists to help decide what further actions may be necessary to ensure that the health of Canadians and their environment are protected.

What Is the Government of Canada Doing?

  • The Government of Canada has determined that DBTMC is not "toxic" as defined under the Canadian Environmental Protection Act, 1999.
  • No further action will be taken on DBTMC.
