Additional information

Conclusion on classification

Classification related key information

 

Biodegradation in water: screening tests: 24% in 28 days (modified OECD 301B).

 

Bioaccumulation: No significant bioaccumulation in biota is expected for this substance (see IUCLID section 5.3).

Acute toxicity:

Fish:   

LL50 (96 h)(Cyprinus carpio): > 100 mg/L (nominal, loading rate)(OECD 203).

Aquatic invertebrates:

EL50 (48 h)(Daphnia magna): > 100 mg/L (nominal, loading rate)(OECD 202).

Algae:

ErL50 (72 h)(Pseudokirchneriella subspicata): 11 mg/L (measured, loading rate)(OECD 201).

 

Chronic toxicity:

Algae:

NOErC (72 h)( Pseudokirchneriella subcapitata): 6.6 mg/L (measured, loading rate)(OECD 201).

 

Non-classification justification according to CLP

Based on the data above, Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates (CAS No. 91052-13-0) is considered to be not rapidly degradable but have low potential for bioaccumulation. The acute L(E)C50 values reported for fish, aquatic invertebrates and algae are > 1 mg/L. Therefore, Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates does not need to be classified and labelled as acute aquatic hazard according to the 2nd ATP of Regulation (EC) No.1272/2008 (CLP).

 

Valid chronic toxicity data are available, with a NOEC value > 1 mg/L for algae. Thus, Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates does not need to be classified and labelled as long-term aquatic hazard according to the 2nd ATP of Regulation (EC) No.1272/2008 (CLP).

 

Non-classification justification according to DSD

Based on the data above,Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates (CAS No. 91052-13-0)is considered to be not rapidly degradable but have low potential for bioaccumulation. The acute L(E)C50 value reported for algae is 11 mg/L, since the NOEC value reported for algae is 6.6 mg/L,Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
