Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on a weight of evidence approach, the toxicity of lavandin oil light fraction to aquatic organisms was estimated with the additivity formula, as recommended in the Regulation (EC) No 1272/2008 (CLP), using adequate toxicity data of major constituents, greater than 1% in the UVCB substance considered as a mixture. Ten constituents were considered, representing about 92% of the mixture.
Based on individual toxicities of these ten major constituents, the LC50 value for lavandin oil light fraction is estimated to be 2.94 mg/L for aquatic invertebrates.
Based on individual toxicities of these ten major constituents, the EC50 value for lavandin oil light fraction is estimated to be 2.62 mg/L for aquatic algae.
According to section 4.1.2.1 of CLP regulation, the lowest of the available toxicity values between and within the different trophic level (fish, crustacean, algae/aquatic plants) shall normally be used to define the appropriate hazard category(ies).
Therefore, as both range of EC50 (algae and daphnia) between 1 and 10 mg/L, the substance is classified H411 according to the table 4.1.0 and figure 4.1.1. of Regulation (EC) No 1272/2008 (CLP).
Additional information
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.
