Conclusion on classification

Biodegradation: not readily biodegradable: 0% in 28 d (OECD 302C)

 

Bioaccumulation: BCF = 159 (OECD 305) 

 

Aquatic short-term toxicity

96 h, LC50 (Brachydanio rerio): 1.1 mg/L (EU method C.1)

48 h, EL50 (Daphnia magna): 2.7 mg/L (EU method C.2)

72 h, ErL50 (Desmodesmus subspicatus): 36.3 mg/L (OECD 201) 

 

Aquatic long-term toxicity

34d, NOEC (Danio rerio): 0.00427 mg/L (OECD 210)

21 d, NOEL (Daphnia magna): 0.189 mg/L (OECD 211)

72 h, NOELR (Desmodesmus subspicatus): 14.9 mg/L (OECD 201)

 

Based on the data above, Benzaldehyde, 2-hydroxy-5-nonyl, oxime, branched (CAS 174333-80-3) is not considered to be rapidly degradable. The bioaccumulation potential is low. Acute aquatic toxicity was observed to be above 1 mg/L. Valid chronic data are available with a NOELR (72 h) of 14.9 mg/L for Desmodesmus subspicatus, a 21d-NOEL of 0.189 mg/L for Daphnia magna and a 34d-NOEC of < 0.1 mg/L (= 0.00427 mg/L) for Danio rerio. Therefore, Benzaldehyde, 2-hydroxy-5-nonyl, oxime, branched needs to be classified and labelled as environmental hazard Chronic Cat. 1 (M = 10) according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).
