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

Equilibrium partitioning gives rise to a soil predicted no effect concentration which was undemanding.

With this in mind, further testing on the substance is considered not necessary.

Key value for chemical safety assessment

Additional information

According to Regulation (EC) No. 1907/2006, Annex X, section 9.4 column 2, Long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on terrestrial organisms. In the absence of toxicity data for soil organisms, the equilibrium partitioning method may be applied to assess the hazard to soil organisms. Wet weight PNECs were calculated with using equilibrium partitioning as described in Guidance R.10 & R.16, conversion to dry weight was performed with factor of 1.13. A further Assessment Factor of 10 was also used to account for the substances high partition coefficient (logKow>5) This gave rise to a soil predicted no effect concentration which was undemanding and as such the chemical safety assessment should conclude safe use of the material. With this in mind, further testing on the substance is considered not necessary.
