Decanedioic acid, bis(1,2,2,6,6-pentamethyl-4-piperidinyl) ester (PEDA)
CAS Registry Number 41556-26-7
What is it?
- Decanedioic acid, bis(1,2,2,6,6-pentamethyl-4-piperidinyl) ester, also known as PEDA, is an industrial chemical.
How is it used?
- PEDA is used in paints and coatings for automobiles and other applications, stain products and plastics to protect them from degradation caused by light.
- This substance is not manufactured in Canada but is imported into Canada.
Why did the Government of Canada assess it?
- Prior to assessment, PEDA was identified as a potential concern to the environment based on information regarding possible persistence, accumulation in organisms and potential to cause harm to organisms.
- PEDA was not considered to be a high priority for assessment of potential risks to human health; however, potential health effects were also evaluated in this screening assessment.
How are Canadians exposed to it?
- The general population of Canada may be exposed to PEDA during the use of consumer products such as automobile interior protectants, waterborne semi-transparent stain products, aerosol solvent borne paints and window sealants. However, this exposure is expected to be low.
How is it released to the environment?
- PEDA may be released to the environment due to industrial container handling and consumer use.
What are the results of the assessment?
- The Government of Canada has conducted a science-based evaluation of PEDA called a screening assessment.
- Screening assessments address potential for harm to the general population (not including workplace exposures) and the environment.
- Results of the final screening assessment indicate that although PEDA has the potential to remain in the environment for a long time, it is not expected to accumulate in organisms.
- Furthermore, the quantity of PEDA that may be released to the environment is below the level expected to cause harm to organisms.
- The Government of Canada has therefore concluded that PEDA is not entering the environment in a quantity or under conditions that constitute a danger to the environment.
- The Government of Canada has also concluded that PEDA is not considered to be harmful to the health of the general population at current levels of exposure.
What is the Government of Canada doing?
- The Government of Canada has assessed PEDA in the event that it were to enter the environment as a result of an environmental emergency and proposes adding PEDA to the Environmental Emergency Regulations of CEPA 1999 so that emergency prevention, preparedness, response and recovery requirements are put in place.
- The final screening assessment report was published on September 18, 2010.
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). PEDA is not a concern for the environment or human health at current levels of exposure.
- As a general precaution, Canadians are reminded when using any product to carefully follow any safety warnings and directions.
- Canadians who handle PEDA in the workplace should consult with their occupational health and safety representative about safe handling practices, applicable laws and requirements under the Workplace Hazardous Materials Information System.
