Endpoint summary

Administrative data

Description of key information

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

The substance is liquid at ambient temperature, with low volatility. In water, it is slightly soluble, with no dissociation anticipated. Despite the standardised test 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

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

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