Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
Physico-chemical properties were determined from experimental testing. Some endpoints were waived, based on chemical structure or experience.
The substance is a low melting solid at ambient temperature, slightly more dense than water, and with low volatility.
In water, it is slightly soluble, with neutral pH, but should display weak surface-active properties. However, 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 and observed behaviour of the substance in the water solubility and partition coefficient studies.
It has potential for bioaccumulation and aquatic chronic toxicity.
It is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.
Moreover, the LR quality contains almost no inhalable particle, and has limited potential for dust explosion.
