- Justification:
The PBT Assessment for glycerol diacetate (technical) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2008).
Persistence
Glycerol diacetate (technical) is readily biodegradable based on one study according to OECD 306 (81 - 108.5 (O2 consumption) after 28 d). Thus, the test substance does not meet the screening criterion for persistency and it is not considered to be persistent (P) or very persistent (vP).
Bioaccumulation
Glycerol diacetate (technical) has a log Kow of -1.24 - 0.36 (KOWWIN v1.68). Thus, the test substance does not meet the screening criterion for bioaccumulation and it is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
Toxicity
Long term toxicity values are available for Daphnia magna (NOEC (21d) ≥ 94 mg/L)for the read-across substance triacetin (in accordance with Regulation (EC) No 1907/2006 Annex XI, 1.5) and Skeletonema costatum (NOEC (72 h): 100 mg/L), both well above the trigger value of 0.01 mg/L.Moreover, the test substance is not classified according to Directive 67/548/EEC and Regulation (EC) No 1272/2008 (2ndATP). Thus, the criteria set out in Annex XIII of Regulation (EC) No 1907/2006 are not met and the test substance is not considered to meet the T criterion.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
