EC number: 627-083-1
CAS number: 244235-47-0
Biodegradation: not readily biodegradable: 0% in 28 d (ISO 10708)
Bioaccumulation: BCF = 159 (OECD 305, read across)
Aquatic short-term toxicity
96 h, LC50 (Brachydanio rerio): 0.46 mg/L (EU method C.1)
48 h, EL50 (Daphnia magna): 9.55 mg/L (OECD 202)
72 h, ErL50 (Desmodesmus subspicatus): > 100 mg/L (OECD
Aquatic long-term toxicity
34d, NOEC (Danio rerio): 0.00427 mg/L (OECD 210, read
21 d, NOEL (Daphnia magna): 2.8 mg/L
72 h, NOELR (Desmodesmus subspicatus): ≥ 100 mg/L (OECD 201)
Based on the data above, Ethanone, 1-(2-hydroxy-5-nonylphenyl)-,
oxime, branched (CAS 244235-47-0) is not considered to be rapidly
degradable. The bioaccumulation potential is low. Acute aquatic toxicity
was observed below 1 mg/L. Valid chronic data are available with a NOELR
(72 h) ≥ 100 mg/L for Desmodesmus subspicatus, a 21d-NOEL
of 2.8 mg/L for Daphnia magna and a 34d-NOEC of < 0.1 mg/L (=
0.00427 mg/L) for the read across substance Benzaldehyde,
2-hydroxy-5-nonyl-, oxime, branched (CAS 174333-80-3). Therefore,
Ethanone, 1-(2-hydroxy-5-nonylphenyl)-, oxime, branched (CAS
244235-47-0) needs to be classified and labelled as environmental hazard
acute Cat.1 (M = 1) and Chronic Cat. 1 (M = 10) according to the 2nd ATP
of the Regulation (EC) No.1272/2008 (CLP).
The acute toxicity is below 1 mg/L and the substance is not
readily biodegradable. Therefore,Ethanone, 1-(2-hydroxy-5-nonylphenyl)-,
oxime, branched (CAS 244235-47-0) needs to be classified and labelled as
environmental hazardous (R50/53) according to Directive 67/548/EEC.
