Conclusion on classification

Classification related key information

Biodegradation in water: screening tests:

86.7% biodegradation in 28 days (OECD 301B)  

                                                 

Bioaccumulation:                       

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

 

Acute toxicity:

-         Fish: LC50 (96 h) > 77.9 mg/L for Oncorhynchus mykiss (OECD 203)

-         Aquatic invertebrates: EC50 (48 h) = 64.4 mg/L for Daphnia magna (OECD 202)

-         Algae: ErC50 (72 h) > 72.6 mg/L for Pseudokirchneriella subcapitata (OECD 201)

Chronic toxicity: 

-         Algae: NOErC (72 h) = 0.565 mg/L for Pseudokirchneriella subcapitata (OECD 201)

Classification justification according to CLP

Based on the data above, Glycerides, palm-oil mono-, hydrogenated, acetates (CAS No. 93572-32-8) is considered to be rapidly biodegradable. The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, aquatic invertebrates and algae. Therefore, Glycerides, palm-oil mono-, hydrogenated, acetates does not need to be classified and labeled as acute aquatic hazard according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP).

 

Valid chronic toxicity data are available for algae, resulting in a NOEC value < 1 mg/L.Thus, the substance needs to be classified and labeled as long-term aquatic Chronic Category 3 according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP).

 

M-factor: not to be assigned

 

Classification justification according to DSD

Based on the data above, Glycerides, palm-oil mono-, hydrogenated, acetates (CAS No. 93572-32-8) is considered to be rapidly biodegradable and have low bioaccumulation potential. The acute aquatic toxicity tests available resulted in EC50 values > 1 mg/L for fish, aquatic invertebrates and algae. Thus, the substance does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
