Endpoint summary

Administrative data

Description of key information

Physico-chemical properties of the substance were determined from experimental testing where relevant, or based on constituent approach when considered more appropriate for a multi-constituent substance. Some endpoints were waived, based on chemical structure of the major constituents.

The substance is a fluid liquid at ambient temperature, much denser than water, with constituents of high volatility.

In water, constituents are regarded as moderately soluble to soluble; no surface-active properties are anticipated.

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

It is NOT classified for physical hazards are anticipated, based on CLP criteria.
