Endpoint summary

Administrative data

Description of key information

Physico-chemical properties were determined from experimental testing, except Vapour Pressure and Surface tension that were derived from an analogue substance. Some endpoints were waived, based on chemical structure or experience.

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

In water, it is slightly soluble, and less dense. Despite the standardised EU.A5 test on a analogue shows surface-active potential under the experimental conditions, it is not considered as a true surfactant, due to the chemical structure of the substance, non-intended use and observed behaviour of the substance in the water solubility and partition coefficient studies.

It has potential for bioaccumulation.

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