1-Propene, 3-chloro- (3-Chloropropene)
CAS Registry Number 107-05-1
What is it?
- 1-Propene, 3-chloro-, also known as 3-chloropropene, is an industrial chemical.
How is it used?
- Internationally, 3-chloropropene is employed primarily in the production of epichlorohydrin, glycerine and quaternary ammonium compounds for the manufacture of resins and polymers.
- 3-Chloropropene can also be used in the manufacture of a variety of miscellaneous products, including allyl compounds, cross-linking substances (chemicals used to make polymers), pharmaceutical agents, agricultural chemicals, plasticizers, fragrances and flavour chemicals.
- Acrylic polymers manufactured by using 3-chloropropene may be used as formulants in some personal care products in which 3-chloropropene may be present at very low (trace) levels as residues (leftover from the manufacturing process).
- 3-Chloropropene is not currently manufactured in Canada, but may be imported into Canada as a residual in some products.
Why is the Government of Canada assessing it?
- Prior to the assessment, 3-chloropropene was identified as a potential concern to human health based on its classification by international organizations as a substance that may cause cancer in laboratory animals and may cause genetic effects, and based on a moderate potential for exposure to Canadians.
How are Canadians exposed to it?
- Exposure of the general population of Canada to 3-chloropropene is expected to be low and to occur predominantly via inhalation of ambient and indoor air and the use of personal care products containing 3-chloropropene as a residual.
What are the results of the assessment?
- The Government of Canada has conducted a science-based evaluation of 3-chloropropene, called a screening assessment.
- The Government of Canada has concluded that 3-chloropropene is not harmful to human health at current levels of exposure.
- The Government of Canada has also concluded that 3-chloropropene is not entering the environment in a quantity or under conditions that constitute a danger to the environment.
What is the Government of Canada doing?
- Although exposure of the general population of Canada is low, the Government is taking action so that exposure remains low.
- The Government of Canada is proposing to implement a Significant New Activity or SNAc provision for 3-chloropropene. This would require that any proposed new manufacture, import or use of 3-chloropropene would be subject to further assessment before this new activity would be allowed.
- The final screening assessment report was published on November 28, 2009.
What can Canadians do?
- The health risks associated with a chemical depend on the hazard (its potential to cause health effects) and the dose (the amount of chemical to which you are exposed).
- Because exposure to 3-chloropropene among the general population is low, the Government of Canada is not currently recommending specific actions by Canadians to reduce their exposure.
- As a general precaution, Canadians who handle 3-chloropropene in an industrial or manufacturing setting are reminded to carefully follow safety warnings and directions when using products containing 3-chloropropene.
