PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Antimony pentachloride
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Antimony pentachloride
- PBT status:
- PBT assessment does not apply
- Justification:
The REACH Regulation (EC) 1907/2006) states that a PBT and vPvB (very persistent very bioaccumulative) assessment shall be conducted as foreseen in Article 14 (3) (d) in conjunction with Annex I Section 4 according to the criteria as laid down in Annex XIII (as updated in Commission Regulation (EU) No 253/2011 of 15 March 2011). The PBT and vPvB criteria of Annex XIII however only apply to organic substances, including organometals.According to the Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.11: PBT/vPvB Assessment, version 3.0 (June 2017), “Annex XIII to the REACH Regulation is generally applicable to any substance containing an organic moiety. Based on the common definition of an organic substance in chemistry, PBT and vPvB criteria are not applicable to inorganic substances.”
The draft Guidance to Regulation (EC) No 1272/2008 on Classification, Labelling and Packaging of substances and mixtures for metals and metal compounds qualitatively distinguishes metals from organometals based on their dissociation behaviour upon dissolution in water: “Organometals do not dissociate or dissolve in water as the metal ion, as metals and inorganic metal compounds do. … Metal compounds that contain an organic component but that dissociate easily in water or dissolve as the metal ion should be treated in the same way as (inorganic) metal compounds".
SbCl5 is beyond doubt an inorganic substance. Therefore, strictly spoken, there is no legal obligation for a PBT and vPvB assessment for SbCl5.
