Conclusion on classification

Classification relevant information for environmental hazard:

Biodegradation:

Based on the results of the read across substances and the QSAR predictions, the target substance dodecanoic acid, ester with 1,2-propanediol (CAS 37321 -62 -3) is considered readily biodegradable. 

 

Aquatic acute toxicity

Aquatic invertebrates:

EL50 (48 h) = 6.59 mg/L (nominal, OECD 202)

Algae/aquatic plant: 

EL50 (72 h) = 31.25 mg/L (nominal, OECD 201)

 

Aquatic chronic toxicity:

NOELR (72 h) = 9.76 mg/L (nominal, OECD 201)

 

Classification according to CLP

Based on the available data listed above, the most sensitive acute effect concentration was obtained for aquatic invertebrates, with an EL50 (48 h) of 6.59 mg/L (nominal). Thus, the substance does not need to be classified for acute aquatic toxicity according to the consolidated version of Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).

The NOELR (72 h) = 9.76 mg/L (nominal) for algae is the only chronic aquatic effect concentration available. As the substance is readily biodegradable and the log Pow is 5.0 to >10, the substance need to be classified for chronic aquatic toxicity according to the Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs) as Aquatic Chronic 2.
