Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
