Physical & Chemical properties

Endpoint summary

Administrative data

Description of key information

Physico-chemical properties of the substance were determined from experimental testing, or from data on constituents where testing was not relevant or feasible for a multiconstituent substance. Some endpoints were waived, based on chemical structures.

The substance is a low melting solid, with low volatility. In water, it is insoluble (< 0.1 mg/L) due to the major constituent, and forms cloudy emulsions.

It has potential for bioaccumulation in organisms.

It is NOT considered as dangerous with regard to physical hazards according to CLP criteria.

Oxidising properties

No potential (based on chemical structure and composition).

Self-reactive properties

No potential (waived, based on chemical structure of constituents)

Organic peroxide

No peroxide in composition.

Note that the numerical parameters may slightly vary from batch-to-batch, due to the multiconstituent nature of the substance.
