EC number: 203-051-9
CAS number: 102-76-1
The PBT Assessment for triacetin (CAS 102-76-1) is based on the criteria
set out in the “Guidance on information requirements and chemical safety
assessment, Chapter R.11: PBT Assessment” (ECHA, 2008).
The screening criterion for Persistence (P) is the potential of a
substance to be readily biodegradable. As triacetin is readily
biodegradable, it is not fulfilling the criteria for Persistence (P) and
is thus “not P” and “not vP”.
The screening criterion for Bioaccumulation (B) is a log Kow >
4.5. As triacetin has a log Kow of 0.25, it is not fulfilling the
screening criteria for Bioaccumulation (B) stipulated in the ECHA’s
guidance on information requirements and chemical safety assessment –
Part C: PBT Assessment (2008). Thus, triacetin can neither be considered
bioaccumulative (B) nor very bioaccumulative (vB).
Triacetin is not classified according to Directive 67/548/EEC and
Regulation (EC) No. 1272/2008 (2nd ATP). Moreover, no long-term toxicity
was observed in a study according to OECD 211. Thus, the criteria
according to Annex XIII of Regulation (EC) No. 1907/2006 are not met and
the substance does not meet the Toxicity (T) criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
