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: < 0.15 mg/l (EU guideline A.6)

Biodegradation: 60 % - 70 % based on O2 consumption and CO2 evolution

BCF: <= 8 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 (< 0.15 mg/l) for D. rerio (OECD 203), read across: LC50 (96h) > 100 mg/l.

For aquatic invertebrates: EC50 (48h) no toxic effects up to the limit of water solubility (< 0.15 mg/l) for D. magna (OECD 202), read across: EC50 (48h) > 100 mg/l.

For algae: EC50 (72h) no toxic effects up to the limit of water solubility (< 0.15 mg/l) for D. subspicatus (OECD 201), read across: EC50 (72h) > 100 mg/l.

Aquatic chronic toxicity:

For fish: no data

For aquatic invertebrates: no data

For algae: ErC10 (72h) no toxic effects up to the limit of water solubility (< 0.15 mg/l) for D. subspicatus (OECD 201), read across

 

Non-Classification justification according to CLP

The acute aquatic toxicity L(E)C50 is above the limit of water solubility for fish, algae and aquatic invertebrates. 2-Butenedioic acid (E)-, di-C8-18-alkyl esters (CAS 68610-90-2).

2-Butenedioic acid (E)-, di-C8-18-alkyl esters (CAS 68610-90-2) is considered to be readily degradable. Valid chronic toxicity data are available for algae – the ErC10 is above the limit of water solubility for both.

Based on the available data on the category substances, 2-Butenedioic acid (E)-, di-C8-18-alkyl esters does not need to be classified and labelled as acute or chronic aquatic hazard according to CLP Regulation (EC) No. 1272/2008.
