Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Additional information

Note that much of the data was proved by ECHA under the 12 year data access rule. No robust summary was available at the time of preparation of this document and some key data was not included in the information from ECHA.

The substance is supplied in powder form with a melting point range estimated 90 - 120 degrees Celsius. The vapour pressure is noticable (9 Pa) but not significant for purposes of environmental or workplace exposure. Dust content is monitored and precautions are needed to prevent generation of dust and reduction of exposure. Dust explosion risk is thought to be slight, but risk management measures should take this into account.

Particle size analysis performed on a 2009 batch of the substance from the non-EU source suggests a mean particle size that is a possible risk of inhalation and risk management measures will include precautions to prevent generation or dust and recommendations to wear dust masks and work in good areas of ventilation.

The substance will rapidly degrade in light (the function is UV curing agent) and showed poor stability in the ecotoxicity studies.

The partition coefficient range 2.6 - 4.1 would suggest a risk of bioaccumulation for some of the less water soluble components. This was performed by HPLC and interaction of light should not have been significant. The substance has been classified as Aquatic Chronic 4, with the protential to cause long term effects in the environment.

The substance demonstrated no surface active properties

There are no reported physical hazards relating to the substance; it does not meet the criteria for flammable, explosive or oxidising.
