Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short-term aquatic toxicity data are available for two trophic levels (invertebrates and algae). The acute effect values for daphnids (Daphnia magna) and algae (Pseudokirchneriella subcapitata) are 1.47 mg/L and 0.342 mg/L, respectively. The substance therefore has to be classified for acute aquatic hazard as Acute 1 (H400
Long-term aquatic toxicity data are available only for aquatic algae for which an ErC10 of 0.274 mg/L was determined. As only one reliable long-term toxicity endpoint is available, chronic classification needs to be based on bothchronic and acutedata of which the most stringent outcome is used for the final classification.
Based on the chronic data and the substance’ readily biodegradability, the substance needs to be classified as Chronic 3 (H412). Based on the acute data of the other trophic level, the substance being readily biodegradable, a log Kow of 5.4 (no experimental BCF is available) and the corresponding acute effect value in the range of 1 - 10 mg/L, the substance needs to be classified as Chronic 2. Therefore, the overall classification for Ocimene will become Acute 1 (H400) and Chronic 2 (H411) according to Regulation 1272/2008/EC (CLP) and its updates.
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.
