Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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. 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 read-across was applied for the substance, data will be generated from representative source substances to avoid unnecessary animal testing. Additionally, once the read-across approach is applied, substances will be classified and labelled on this basis.

Degradation

Biodegradation: readily biodegradable: 68.1 - 71.7% (CO2 evolution) after 29 d; read-across

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.  

Aquatic acute toxicity

96 h, LL50 (Cyprinus carpio): > 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

48 h, EL50 (Daphnia magna): > 86 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

72 h, ErL50 (Selenastrum capricornutum): > 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

Aquatic chronic toxicity

72 h, NOELR (Selenastrum capricornutum): ≥ 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

21 d, NOELR (Daphnia magna): ≥ 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

CLP

Based on the data above, isooctadecyl isooctadecanoate is considered to be rapidly degradable. No acute aquatic toxicity was observed up to the water solubility limit (0.044 mg/L at 20 °C) for fish, algae and daphnids. Valid chronic data are available with a NOELR (72 h) ≥ 100 mg/L for the algae Selenastrum capricornutum and a NOELR (21 d) ≥ 100 mg/L for Daphnia magna. Therefore, isooctadecyl isooctadecanoate does not need to be classified and labelled as environmental hazard according to the 2nd ATP of the Regulation (EC) No 1272/2008 (CLP). 

DSD

The substance is poorly soluble in water and no effects occurred up to its solubility limit in acute tests for fish, algae and aquatic invertebrates. Therefore, isooctadecyl isooctadecanoate does not need to be classified and labelled as environmental hazardous according to Directive 67/548/EEC.
