Resin acids and Rosin acids, fumarated, barium salts (RFBS)

CAS Registry Number 124751-15-1

What is it?

  • Resin acids and Rosin acids, fumarated, barium salts, also known as RFBS, is an industrial chemical.

How is it used?

  • RFBS may have been used previously in pigments, dyes, and printing inks.
  • This substance is not currently manufactured in Canada or imported into Canada.

Why did the Government of Canada assess it?

  • Prior to assessment, RFBS 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.
  • In addition, RFBS was believed to be potentially in commerce in Canada prior to assessment.

How is it released to the environment?

  • The Government of Canada has reviewed information that indicates that RFBS is not in commerce in Canada.
  • As a result, it is unlikely that RFBS is entering the environment as a result of commercial manufacture, import or use in this country.

What are the results of the assessment?

  • The Government of Canada has conducted a science-based evaluation of RFBS 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 RFBS has the potential to remain in the environment for a long time, accumulate in organisms and cause harm to organisms, but that the substance is not presently a concern because it is not in commerce.
  • The Government of Canada has therefore concluded that RFBS is not entering the environment in a quantity or under conditions that constitute a danger to the environment.
  • Because RFBS is not currently in commerce in Canada, it 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 application of the Significant New Activity (SNAc) provisions to this substance will be recommended. This would require that any proposed new manufacture, import or use be subject to further assessment, and would determine if the new activity requires further risk management consideration.
  • The final screening assessment report was published on January 15, 2011.

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). Since RFBS is not in commerce, it is not a concern for the environment or human health.
  • As a general precaution, Canadians are reminded to carefully follow any safety warnings and directions when using any product.
