2,9,11,13-Tetraazanonadecanethioic acid, 19-isocyanato-11-(6-isocyanatohexyl)-10,12-dioxo-, S-[3-(trimethoxysilyl)propyl] ester (TIDTE)
CAS Registry Number 85702-90-5
What is it?
- 2,9,11,13-Tetraazanonadecanethioic acid, 19-isocyanato-11-(6-isocyanatohexyl)-10,12-dioxo-, S-[3-(trimethoxysilyl)propyl] ester, also known as TIDTE, is an industrial chemical.
How is it used?
- TIDTE is used as a component of marine adhesives and sealants.
- This substance is not manufactured in Canada but is imported into Canada.
Why did the Government of Canada assess it?
- Prior to assessment, TIDTE 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.
- TIDTE 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 is it released to the environment?
- The release of TIDTE to the environment is expected to be minor as the majority of the substance is expected to be transformed through chemical reactions with other components of formulations containing this substance.
How are Canadians exposed to it?
- The general population of Canada may be exposed to TIDTE during the use of marine adhesive sealant; however, this exposure is expected to be very low.
What are the results of the assessment?
- The Government of Canada has conducted a science-based evaluation of TIDTE 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 TIDTE is not expected to remain in the environment for a long time, accumulate in organisms, or cause harm to organisms.
- The Government of Canada has therefore concluded that TIDTE 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 TIDTE is not harmful to the health of the general population at current levels of exposure.
What is the Government of Canada doing?
- Based on the conclusion of the final screening assessment, no further action will be taken on TIDTE.
- 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). TIDTE is not a concern for the environment or human health at current levels of exposure.
- As a general precaution, Canadians are reminded to carefully follow any safety warnings and directions when using any product.
- Canadians who handle TIDTE 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 (WHMIS).
