Physical & Chemical properties

Endpoint summary

Administrative data

Description of key information

Physico-chemical properties were determined from experimental testing. Some endpoints were waived, based on chemical structure of the constituents.

The substance is liquid at ambient temperature, with low volatility.

In water, it is slightly soluble, less dense (so expected to float), with no dissociation anticipated, and no significant surface-active properties.

It has potential for bioaccumulation and aquatic chronic toxicity, based on CLP criteria.

It is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.
