Endpoint summary

Administrative data

Description of key information

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

The substance is a low-melting solid at ambient temperature, but can also exist as supercooled liquid, with low volatility.

In water, it is moderately soluble, and slightly denser.

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, and non-intended use.

It has low 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.
