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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 284-545-1 | CAS number: 84929-61-3 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Daucus carota, Umbelliferae.
Endpoint summary
Administrative data
Description of key information
The key ecotoxicity values of the registered substance are as follow:
- Aquatic Invertebrates: 48-h EL50 is 11 mg test material/L (lowest acute E(L)C50 value)
- Aquatic algae: 72-h ErL50 is 13 mg test material/L
Based on these results, the lowest acute E(L)C50 is higher than 1 mg/L.
Therefore, the registered substance would not be classified as acute 1 to aquatic organisms in accordance with the classification of the CLP.
Additional information
The registered substance Carrot seeds oil is a Natural Complex Substance (UVCB) composed by two qualities: one rich in carotol and another one rich in geraniol. Both qualities have well-defined compositions for which typical percentages of the constituents are known. The mixture ecotoxicity properties may be derived from the ecotoxicity of the individual constituents. Therefore, it has been decided that the ecotoxicity of the substance will be derived from knowledge of the constituents.
Key acute toxicities to daphnids and freshwater algae have been determined using a calculation method that replaces OECD 201 and 202 studies and guideline for Testing of Chemicals No. 23 (i.e. WAF conditions). For these studies, the typical compositions of both qualities have been investigated. For each endpoint, one toxicity value was predicted for each quality of the substance. The key value selected for each endpoint was the most conservative value between both qualities. This calculation method was based on HA-QSARs fully validated following the OECD (2004) recommendations. It was considered acceptable to be used alone to fulfill annex VII ecotoxicological endpoints.
Moreover, short-term toxicity to fish was not provided in the data set because the tonnage band does not require this endpoint.
CLP Classification proposal
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).
Acute aquatic hazard: not classified. Reasoning: lowest E(L)C50 higher than 1 mg/L.
Chronic aquatic hazard: category 3. Reasoning: adequate chronic toxicity data are not available, lowest acute E(L)C50 value is between 10 and 100 mg/L, not rapidly degradable substance with at least one constituent having a Log Kow > 4.
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.
