Propanamide, N-[5-[bis[2-(acetyloxy)ethyl]amino]-2-[(2-chloro-4-nitrophenyl)azo]phenyl]- (Disperse Red 167)

CAS Registry Number 26850-12-4

What is it?

  • Propanamide, N-[5-[bis[2-(acetyloxy)ethyl]amino]-2-[(2-chloro-4-nitrophenyl)azo]phenyl]- , also known as Disperse Red 167, is an industrial chemical.

How is it used?

  • Disperse Red 167 is used as a red colorant, mainly in textiles and fabric.
  • Based on the most recent data available, Disperse Red 167 is not manufactured in Canada but is imported into Canada.

Why did the Government of Canada assess it?

  • Prior to assessment, Disperse Red 167 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.

How is it released to the environment?

  • Disperse Red 167 may be released to the environment during industrial processes and consumer use.
  • Upon its release, most of the substance is expected to end up in solid waste disposal sites. A significant proportion is also estimated to be released to sewer water.
  • Disperse Red 167 may remain in the environment for a long time when released. However, data suggests that the substance does not significantly accumulate in or directly harm organisms.

What are the results of the assessment?

  • The Government of Canada has conducted a science-based evaluation of Disperse Red 167 called a screening assessment.
  • Results of assessment indicate that although Disperse Red 167 may remain in the environment for a long time, the substance is not expected to accumulate in organisms.
  • Furthermore, the quantity of Disperse Red 167 that may be released to the environment is below the level expected to cause harm to organisms.
  • The Government of Canada has therefore determined that Disperse Red 167 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?

  • Based on the conclusion of the final screening assessment, no further action is required for this substance.
  • The final screening assessment was published on August 22, 2009.

What could Canadians do?

  • Since Disperse Red 167 is not presently a concern for the environment or human health, Canadians do not currently need to take any specific actions with respect to this chemical.
