Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
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. In Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X”, it is stated 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”.
A read-across approach was applied to this substance and data was compiled from representative source substances to avoid unnecessary animal testing. The target substance will be classified and labelled on this basis.
Environmental fate and pathways
Degradation: Not readily biodegradable (13% after 28 d, OECD 301F)
Bioaccumulation: Log Pow >10 (QSAR)
Aquatic short-term toxicity
Fish: LL50 > 100 mg/L (OECD 203, D. vario); read-across
Aquatic invertebrates: EC50 (48 h) >100 mg/L (OECD 202, D. magna)
Algae: EC50 (72 h) >100 mg/L (OECD 201, P. subcapitata)
Aquatic long-term toxicity
Fish: No data available
Aquatic invertebrates: No data available
Algae: NOEC (72 h)≥ 100 mg/L (OECD 201, P. subcapitata).
Conclusion on CLP
The substance Sorbitan tridocosanoate (CAS 93980-59-7) is not readily biodegradable and has a log Pow >10. No acute or chronic toxic effects were observed at the limit of water solubility for fish, aquatic invertebrates and algae. All available effect concentrations are > 1 mg/L. Thus, the substance does not need to be classified and labelled as environmentally hazardous according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
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.
