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 the group concept is applied to the category members of the Glycol Esters, 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.

 

Degradation

Biodegradation: 61% of Fatty acids, C16-18, esters with ethylene glycol (ISO 10708)

 

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.

 

Aquatic acute toxicity

 

Fish

96 h, LC50 (Oncorhynchus mykiss): No observed toxicological effects up to the water solubility limit > 0.3 mg/L, (read across)

96 h, LC0 (Brachydanio rerio): No observed toxicological effects up to the water solubility limit ≥ 1000 mg/L, (read across)

 

Aquatic invertebrates

48 h, EC50 (Daphnia magna): No observed toxicological effects up to the water solubility limit > 2.7 mg/L, (read across)

48 h, EL50 (Daphnia magna): No observed toxicological effects up to the water solubility limit > 2 mg/L, (read across)

 

Aquatic algae

72 h, EC50 (Scenedesmus subspicatus): No observed toxicological effects up to the water solubility limit > 100 mg/L

Aquatic chronic toxicity

21 d, NOELR (Daphnia magna): No observed toxicological effects up to the water solubility limit ≥ 0.02 mg/L,(read across)

CLP:

Based on the data above,Fatty acids, C16-18, esters with ethylene glycol (CAS 91031-31-1) is considered to be rapidly degradable. No acute aquatic toxicity was observed up to the water solubility limit (< 0.05 mg/L) for fish, aquatic invertebrates and aquatic algae. Valid chronic data are available with a NOELR (21 d) ≥ 0.02 mg/L (i.e. above the limit of water solubility) for Daphnia magna. Therefore,Fatty acids, C16-18, esters with ethylene glycol does not need to be classified and labelled as environmental hazardous according to the Regulation (EC) No 1272/2008 and the Regulation (EU) No 286/2011 (2nd ATP).

DSD:

Fatty acids, C16-18, esters with ethylene glycol (CAS 91031-31-1) is poorly soluble in water (< 0.05 mg/L) and no effects occurred up to its solubility limit in acute tests forfish, aquatic invertebrates and aquatic algae. Therefore, the test substancedoes not need to be classified and labelled as environmental hazardous according to Directive 67/548/EEC.
