Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The 48 hr LC50/EC50 values for Daphnia magna exposed to the four main components of the reaction mass, n-hexane (CAS No. 110-54-3), cyclohexane (CAS No. 110-82-7), Toluene (CAS No. 108-88-3) and 4-vinylcyclohexene (CAS No. 100-40-3), ranged from 0.90 mg/L to 3.78 mg/L.
Key value for chemical safety assessment
Additional information
Reliable experimental studies were available for two of the main components of the reaction mass, cyclohexane (Adam et al, 1987: 48 hr EC50 0.9 mg/L) and toluene (Niederlehner et al,1998: 48 hr LC50 3.78 mg/L).
In the absence of reliable experimental studies the short term toxicity to aquatic invertebrates for the two remaining main components, were predicted using the QSAR model ECOWIN v1 ECOSAR Classes for Microsoft Windows. The model predicted 48 hr LC50 values of 3.33 mg/L for n-hexane and 1.81 mg/L for 4-vinylcyclohexene.
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.
