Additional information

Conclusion on classification

Based on read-across from the structurally similar substances, the available data on aquatic toxicity do not meet the classification criteria according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.

Degradation

Biodegradation: not readily biodegradable (6% after 60 d, OECD 301B)

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.

Aquatic acute toxicity

96 h, LL50 (Rainbow trout) > 100 mg/L (nominal), (read across), no observed toxicological effects up to the water solubility limit (< 0.05 mg/L)

48 h, EL50 (Daphnia magna) > 1000 mg/L (nominal), (read across), no observed toxicological effects up to the water solubility limit (< 0.05 mg/L)

72 h, EL50 (Scenedesmus subspicatus) > 100 mg/L, (read across), no observed toxicological effects up to the water solubility limit (< 0.05 mg/L)

Aquatic chronic toxicity

72 h, NOELR (Scenedesmus subspicatus) ≥ 100 mg/L, (read across), no observed toxicological effects up to the water solubility limit (< 0.05 mg/L)

CLP:

Based on the data above, for2,2-bis[[(1-oxoisononyl)oxy]methyl]-1,3-propanediyl diisononanoate(CAS 93803-89-5) no acute aquatic toxicity was observed up to the water solubility limit (< 0.05 mg/L) for fish, algae and aquatic invertebrates. Valid chronic data are available with a NOELR (72 h) > 100 mg/L (i.e. above the limit of water solubility) for algae. Therefore,2,2-bis[[(1-oxoisononyl)oxy]methyl]-1,3-propanediyl diisononanoatedoes not meet the criteria for classification and labelling as environmental hazardous according to the Regulation (EC) No 1272/2008 and the Regulation (EU) No 286/2011 (2nd ATP).

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,2,2-bis[[(1-oxoisononyl)oxy]methyl]-1,3-propanediyl diisononanoatedoes not meet the criteria for classification and labelling as environmental hazardous according to Directive 67/548/EEC.
