Physical & Chemical properties

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 solid at ambient temperature, with low volatility. In water, it is soluble.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 not intended use.

It has low potential for bioaccumulation.

It is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.However, dust explosion potential should be considered, due to low particle size.
