Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Laurel leaf oil is a Natural Complex Substance (UVCB) with a well-defined composition for which the relative percentage and its reported variation of each constituent is known.
Therefore, it has been decided that the ecotoxicity of Laurel leaf oil will be derived from knowledge of the constituents: constituents approach. The mixture ecotoxicity properties may be derived from the ecotoxicity of the individual constituents (as reported in endpoint summary discussions for each species)
Short-term toxicity to fish is provided in the dataset even if the tonnage band (1 -10 tonnes/year) does not require that endpoint. Indeed that endpoint is fulfilled according to environmental classification rules. Classification should be derived from the most sensible species. Because toxicity data have demonstrated the lowest LC50 values for constituents, it has been decided to calculate fish L(E)C50, in order to ascertain the classification for environment of Laurel leaf oil.
Acute toxicities to aquatic organisms property have been investigated using CLP’s additivity calculation. The “typical” composition proposed by the Lead registrant has been investigated for ecotoxicity.
Using this conservative worst case approach, ecotoxicity results are as follow:
- Fish: 96-h LC50 was 1.60 mg test material/L
- Invertebrate: 48-h EC50 was 1.91 mg test material/L
- Algae: 72-h ErC50 was 2.01 mg test material/L
Based on these results, Laurel leaf oil would not be classified as acute 1 to aquatic organisms in accordance with the classification of the CLP.
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.
