Bis(2-hydroxyethyl)ammonium acetate

Endpoint summary

Additional information

Derived from its physicochemical properties and environmental exposure patterns, DEA acetate is not considered to pose a risk to the environment.

 

Companies under this joint submission manufacture DEA acetate for their own use as a grinding agent for cement manufacturing, therefore the substance is manufactured and used onsite and then incorporated in cement at very low concentrations where any release to the environmental compartments is negligible.

 

Manufacturing, transport, charge and discharge are conducted in closed systems under controlled operational conditions with correspondent risk management measures implemented, therefore release to the environment is unlikely during the manufacturing process. Negligible accidental leakages can occur during sampling or maintenance operations and no environmental exposure is expected in the final product use.

 

Taking into account other relevant chemical properties affecting DEA acetate’s behaviour in the environment, the low partition coefficient (a log Pow expected to be below -1.31) indicates a low potential for bioaccumulation, and a low potential for sediment absorption. Moreover, TEA acetate, a structurally-related read-across compound, is considered inherently biodegradable, as it is degraded up to 60% after 28 days in aqueous solution under experimental conditions.

 

For the reasons stated above, DEA acetate exposure to the environment is not likely to occur. If environmental exposure did occur DEA acetate its unlikely to be persistent or bioaccumulate. Thus, combined with the low aquatic toxicity, indicates this substance is of low environmental concern.
