Endpoint summary

Administrative data

Description of key information

Physico-chemical properties were determined from experimental testing, or calculated from QSAR. Some endpoints were waived, based on chemical structure or experience.

The substance is liquid at ambient temperature, less dense than water, and with low volatility.

In water, it is slightly soluble, with no surface-active properties anticipated.

It has low potential for bioaccumulation.

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