Additional information

Conclusion on classification

Classification related key information

Biodegradation in water: screening tests: 81.7% 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: LL50 (96 h) > 70 mg/L (loading rate) and > 2.0 mg/L (measured concentration) for Danio rerio (OECD 203)

-         Aquatic invertebrates: EL50 (48 h) > 100 mg/L (loading rate) and > 10.7 mg/L (measured concentration) for Daphnia magna (OECD 202)

-         Algae: ErL50 (72 h) = 67.6 mg/L (loading rate) for Desmodesmus subspicatus (OECD 201)

Chronic toxicity: 

-         Algae: NOErLR (72 h) = 20.9 mg/L (loading rate) and 1.7 mg/L (measured concentration) for Desmodesmus subspicatus (OECD 201)

 

Classification justification according to CLP

Based on the data above, Glycerides, mixed C8-10 and succinyl (CAS No. 91744-56-8) is considered to be rapidly biodegradable. The acute aquatic toxicity L(E)L50 values are > 1 mg/L for fish, aquatic invertebrates and algae. Therefore, Glycerides, mixed C8-10 and succinyl does not need to be classified and labeled as acute aquatic hazard according to the 2nd ATP ofRegulation (EC) No. 1272/2008 (CLP).

 

Valid chronic toxicity data are available for algae, resulting in a NOEC value > 1 mg/L. Thus, Glycerides, mixed C8-10 and succinyl does not need to be classified and labeled as long-term aquatic hazard according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP).

  

Classification justification according to DSD

Based on the data above, Glycerides, mixed C8-10 and succinyl (CAS No. 91744-56-8) is considered to be rapidly biodegradable and have low bioaccumulation potential. The acute aquatic toxicity tests available resulted in L(E)L50 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.
