Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification related key information

Log Kow: > 7.7 (KOWWIN v1.68)

Water solubility: < 0.05 mg/L

Biodegradation: 89 % in 29 days (OECD 301B)

Aquatic acute toxicity:

For fish: No effects up to the limit of water solubility (< 0.05 mg/L at 20 °C; OECD 203, Cyprinodon variegatus); read-across

For algae: No effects up to the limit of water solubility (< 0.05 mg/L at 20 °C; OECD 201, Scenedesmus subspicatus); read-across

For aquatic invertebrates: No data available

Aquatic chronic toxicity:

For fish: No data available

For algae: No effects up to the limit of water solubility (< 0.05 mg/L at 20 °C; OECD 201, Scenedesmus subspicatus); read-across

For aquatic invertebrates: No effects up to the limit of water solubility (< 0.05 mg/L at 20 °C; OECD 211, Daphnia magna); read-across

Classification according to CLP

Based on the data above, the acute aquatic toxicity L(E)C50 is above the limit of water solubility for fish, algae and aquatic invertebrates. Hexanedioic acid, di-C16-18 alkyl esters (CAS 92969-90-9) does not need to be classified and labeled as acute aquatic hazard according to the consolidated version of Regulation (EC) No.1272/2008 (01.01.2017) considering all further amendments (ATPs).

Hexanedioic acid, di-C16-18 (even numbered)-alkyl esters (CAS 92969-90-9) is considered to be rapidly degradable. Valid chronic toxicity data are available to algae and aquatic invertebrates– the NOEC values are above the limit of water solubility. Therefore, Hexanedioic acid, di-C16-18 alkyl esters (CAS 92969-90-9) does not need to be classified and labeled for long-term aquatic hazard according to consolidated version of Regulation (EC) No.1272/2008 (01.01.2017) considering all further amendments (ATPs).
