Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to Article 13 of Regulation (EC) No 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", Information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met. Annex XI, “General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint”. Since read-across was applied for the substance, data will be generated from representative source substances to avoid unnecessary animal testing. Additionally, once the read-across approach is applied, substances will be classified and labelled on this basis.
Degradation
Biodegradation: readily biodegradable: 69.9 - 75.3% after 28 d; read-across
Bioaccumulation
No data available
Aquatic acute toxicity
Fish: No data available
Aquatic invertebrates: No data available; Long-term data available
Aquatic algae:
72 h, ErL50 (Desmodesmus subspicatus): > 100 mg/L (nominal; no observed
toxicological effects up to the water solubility limit); read-across
72 h, ErL50 (Selenastrum capricornutum): > 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across
Aquatic chronic toxicity
Fish: No data available
Aquatic invertebrates: 21 d, NOELR (Daphnia magna): ≥ 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across
Aquatic algae:
72 h, NOELR (Selenastrum capricornutum): ≥ 100 mg/L (nominal; no
observed toxicological effects up to the water solubility limit);
read-across
21 d, NOELR (Daphnia magna): ≥ 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across
CLP
Based on the data above, Octadecanoic acid, C16-20-branched alkyl esters (CAS 85203-92-5) is considered to be rapidly degradable. No aquatic toxicity was recorded in the available experimental studies up to the limit of water solubility. Therefore, Octadecanoic acid, C16-20-branched alkyl esters does not need to be classified and labelled as environmental hazard according to the 6th ATP of Regulation (EC) No 1272/2008 (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.
