Acetamide, N-[5-[bis[2-(acetyloxy)ethyl]amino]-2-[(2-bromo-4,6-dinitrophenyl)azo]-4-ethoxyphenyl]- (Disperse Blue 79)
CAS Registry Number 12239-34-8
What is it?
- Acetamide, N-[5-[bis[2-(acetyloxy)ethyl]amino]-2-[(2-bromo-4,6-dinitrophenyl)azo]-4-ethoxyphenyl]-, also known as Disperse Blue 79, is an industrial chemical.
How is it used?
- Disperse Blue 79 is used as a blue colorant dye, mainly in textiles and fabric.
- Based on the most recent data available, Disperse Blue 79 is not manufactured in Canada but is imported into Canada.
Why did the Government of Canada assess it?
- Prior to assessment, Disperse Blue 79 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 Blue 79 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 Blue 79 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 Blue 79 called a screening assessment.
- Results of assessment indicate that although Disperse Blue 79 may remain in the environment for a long time, the substance is not expected to accumulate in organisms.
- Furthermore, the quantity of Disperse Blue 79 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 Blue 79 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 Blue 79 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.
