Conclusion on classification

Classification related key information

Log Kow: 5.82 (OECD 123); > 10 (KOWWIN v.1.68)

Water solubility: < 0.15 mg/L (EU Method A.6)

Biodegradation: 90 % in 29 days (OECD 301B)

BCF: < 130 L/kg (BCFBAF v3.01) 

Aquatic acute toxicity:

For fish: 96h, LL50 (Danio rerio): no effects up to the limit of water solubility

For algae: 72h, ErL50 (P. subcapitata): no effects up to the limit of water solubility

For crustacea: 48h, EL50 (D. magna): no effects up to the limit of water solubility

Aquatic chronic toxicity:

For fish: not available

For algae: 72h, ErL10 (P. subcapitata): no effects up to the limit of water solubility

For crustacea: 21d, NOELR (D. magna): no effects up to the limit of water solubility, read across 

Non-Classification justification according to CLP

Based on the data above, Hexanoic acid, 2-ethyl-, C16-18 alkyl esters (CAS No. 90411-68-0) is considered rapidly degradable. The acute aquatic toxicity L(E)C50 values are above the solubility of the substance in water for fish, algae and daphnia. Valid chronic toxicity data are available for algae and Daphnia – showing that the NOEC values are above the solubility of the substance in water. Therefore, Hexanoic acid, 2-ethyl-, C16-18 alkyl esters (CAS No. 90411-68-0) does not need to be classified and labelled as environmental hazard according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2nd ATP).

Non-Classification justification according to DSD

Based on the data above, Hexanoic acid, 2-ethyl-, C16-18 alkyl esters (CAS No. 90411-68-0) is rapidly degradable and is considered to have a low potential for accumulation. The acute aquatic toxicity L(E)C50 is above the solubility of the substance in water for fish, algae and daphnia. Therefore, Hexanoic acid, 2-ethyl-, C16-18 alkyl esters (CAS No. 90411-68-0) does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
