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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
