Additional information

Conclusion on classification

Classification related key information

Biodegradation in water: screening tests: 1 – 7% (O2 consumption and DOC removal) in 28 days (OECD 301A and 301C)

Log Kow: 1.92 (OECD 107 and OECD 117)

Acute toxicity:

- to fish: LC50 (96h) > 100 mg/L forOryzias latipes(OECD 203)

- to aquatic invertebrates: EC50 (48h) = 340 mg/L forDaphnia magna(OECD 202)

- to algae: ECr50 (72h) > 100 mg/L forPseudokirchneriella subcapitata(OECD 201)

Chronic toxicity:

- to fish: not available

- to aquatic invertebrates: not available

- to algae: NOEC (72h) = 10 mg/L forPseudokirchneriella subcapitata(OECD 201)

 

Classification justification according to CLP

Based on the data above, triallyl isocyanurate is considered not rapidly biodegradable. The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, aquatic invertebrates and algae. Valid chronic toxicity data are available for algae with a NOEC > 1mg/L. Therefore, triallyl isocyanurate does not need to be classified as environmental hazard according to the Regulation (EC) No. 1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2ndATP).

 

Classification justification according to DSD

Based on the data above, triallyl isocyanurate is considered to have a low potential for bioaccumulation and is not rapidly degradable. The acute aquatic toxicity L(E)C50 values are > 100 mg/L for fish, aquatic invertebrates and algae. Therefore, triallyl isocyanurate does not need to be classified according to Directive 67/548/EEC.
