Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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 the group concept is applied to the category members of the PFAE linear, data will be generated from a representative category member to avoid unnecessary animal testing. Additionally, once the group concept is applied, substances will be classified and labelled on this basis.

Conclusion on classification

Classification related key information

Log Kow: 5.17 (KOWWIN v.1.68)

Water solubility: 2 mg/L (EU Guideline A.6)

Biodegradation: 90 % in 28 days (OECD 301B)

BCF: 16.9 L/kg (BCFBAF v3.01; Arnot-Gobas estimate) 

Aquatic acute toxicity:

For fish: LC50 (96h) no toxic effects up to the limit of water solubility (2 mg/L) for fish (OECD 203), read cross

For algae: EC50 (72h) no toxic effects up to the limit of water solubility (2 mg/L) for algae (OECD 201)

For crustacea: EC50 (48h) no toxic effects up to the limit of water solubility (2 mg/L) for D. magna (OECD 202)

Aquatic chronic toxicity:

For fish: no data

For algae: NOEC (72h) no toxic effects up to the limit of water solubility (2 mg/L) for algae (OECD 201)

For crustacea: no data

Non-Classification justification according to CLP

Based on the data above, Diisopropyl sebacate (CAS 7491-03-2) is considered rapidly degradable. The acute aquatic toxicity L(E)C50 values are > 1 mg/L and the solubility of the substance in water for fish, algae and daphnia. Valid chronic toxicity data are available for algae – showing that the NOEC value is above the solubility of the substance in water. Therefore, Diisopropyl sebacate (CAS 7491-03-2) does not need to be classified and labelled as environmental hazard according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2nd ATP).

Non-Classification justification according to DSD

Based on the data above, Diisopropyl sebacate (CAS 7491-03-2) is rapidly degradable and is considered to have a low potential for accumulation. The acute aquatic toxicity L(E)C50 is > 100 mg/L and the solubility of the substance in water for fish, algae and daphnia. Therefore, Diisopropyl sebacate (CAS 7491-03-2) does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
