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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

TL0 (48h) = 1000 mg/l
Key value for chemical safety assessment
Additional information
No data on target substance was available, thus available data on Similar Substance 01 was used. Similar Substance 01 is one component of the target UVCB substance; it is one of the major components, ranging between 10 - 60 % w/w. Other components show slight differences in terms of position / type of functional groups. Further details are available in section 13.
Acute toxicity of test substance to fish was assessed in a 48 -hour study on trout. Only a summary of results was available. In particular, no mortality was seen up to the highest tested dose of 1000 mg/l, thus TL50 > 1000 mg/l. Purity of test sample was 75 %. As no details were available, such result was only taken as a qualitative indication of low toxicity.
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.
