Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 fumarates, 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: > 10 (KOWWIN v1.68)

Water solubility: < 0.05 mg/L (EU guideline A.6)

Biodegradation: 62 % (CO2 evolution) in 28 days (OECD 301B)

BCF: <1 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 (< 0.05 mg/L in aqua dest) for D. rerio (EU method C.1)

For aquatic invertebrates: EC50 (48h) no toxic effects up to the limit of water solubility (< 0.05 mg/L in aqua dest) for D. magna (EU method C.2)

For algae: EC50 (72h) no toxic effects up to the limit of water solubility (< 0.05 mg/L in aqua dest) for D. subspicatus (OECD 201)

Aquatic chronic toxicity:

For fish: no data

For aquatic invertebrates: no data

For algae: NOEC (72h) no toxic effects up to the limit of water solubility (< 0.05 mg/L in aqua dest) for D. subspicatus (OECD 201)

Non-Classification justification 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. Therefore, 2-Butenedioic acid (E)-, di-C18 -22-alkyl esters (CAS 68921-53-9) does not need to be classified and labeled as acute aquatic hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).

2-Butenedioic acid (E)-, di-C18 -22-alkyl esters (CAS 68921-53-9) is considered to be rapidly degradable. Valid chronic toxicity data are available for algae – the NOEC is above the limit of water solubility. Therefore, 2-Butenedioic acid (E)-, di-C18 -22-alkyl esters (CAS 68921-53-9) does not need to be classified and labeled as long-term aquatic hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).

Non-Classification justification according to DSD

Based on the data above, 2-Butenedioic acid (E)-, di-C18 -22-alkyl esters (CAS 68921-53-9) is rapidly degradable and is considered to have a low potential for accumulation. The acute aquatic toxicity L(E)C50 is above the limit of water solubility in water for fish, algae and daphnia. Therefore, 2-Butenedioic acid (E)-, di-C18 -22-alkyl esters (CAS 68921-53-9) does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
