Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

No toxic effects were observed at the highest tested doses on fishes and invertebrates resulted on LC50/96h > 100.3 mg/L a.i. and EC50/48h > 96 mg/L a.i. respectively. A 72 hours test on algae led to an EC50 = 598 mg/L a.i. and an EC10 = 262 mg/L a.i.

A log Kow of 1.57 was found by the HPLC method and indicates a low potential for bioaccumulation in absence of BCF data.

The substance was only degraded by 14% in a ready biodegradation study but by analogy with 2,2-dimethyl-1,3-dioxolan-4-ylmethanol, the substance can be considered as inherently biodegradable.

Thus the substance is not classified for environmental hazards according to CLP regulation and DSD directive.
