Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The hazard assessment is based on the data currently available. New studies (including long-term studies) with the registered substance will be conducted in the future. The finalised studies will be included in the technical dossier as soon as they become available and the hazard assessment will be re-evaluated accordingly.


In order to fulfil the standard information requirements, according to Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from structurally related substances was conducted. 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”.


Short-term tests with freshwater species of three trophic levels (fish, daphnia, algae) are available for appropriate read-across category members of Fatty Acid Glycerides. Organisms on all trophic levels (fish, daphnia, algae) did not show any effects up to the limit of water solubility. The toxicity control performed within the scope of the biodegradation screening test (OECD 301 F) revealed no toxic effects on aquatic microorganisms.


Based on the results from available studies on structurally related read-across substances (in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) it can be concluded that the target substance Octanoic acid, monoester with glycerol (CAS 26402-26-6) has no toxic effects on freshwater organisms up to the limit of the water solubility.
