Degradation
Biodegradation: Readily biodegradable: 76-82% (CO2 evolution) after 28 d (OECD 301B)
Bioaccumulation
Log Kow: 0.25 (KOWWIN, exp. database match)
Aquatic acute toxicity
LC50 (96 h) > 100 mg/L for Oryzias latipes (OECD 203)
EC50 (48 h) 380 mg/L for Daphnia magna (EU Method C.2)
ErC50 (72 h) > 940 mg/L for Selenastrum capricornutum (OECD 201)
Aquatic chronic toxicity
NOEC (72 h) 468 mg/L for Selenastrum capricornutum (OECD 201)
NOEC (21 d) ≥ 94 mg/L for Daphnia magna (OECD 211)
Non-classification according to CLP
Based on the data above, triacetin (CAS 102-76-1) is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute toxicity L(E)C50 and chronic NOEC for algae and aquatic invertebrates are all > 1 mg/L. Thus, triacetin does not need to be classified and labeled as environmental hazard according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP).
Non-classification according to DSD/DPD
Based on the data above, triacetin (CAS 102-76-1) is considered to be rapidly degradable and has low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are all > 1 mg/L for fish, aquatic invertebrates and algae. Thus, triacetin does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
