Endpoint summary
Administrative data
Description of key information
No test was performed on skin and eye irritation/corrosion, as the complex is composed of boron trifluoride and orthophosphoric acid. Both substances are considered as corrosive to skin and eyes.
Key value for chemical safety assessment
Skin irritation / corrosion
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (corrosive)
Eye irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Additional information
The test substance shows a corrosive potential in the Corrositex® - Skin Corrosion Test (OECD Guideline 435) and should be assigned to UN GHS skin corrosivity subcategory 1A. The test substance is a complex composed of boron trifluoride and orthophosphoric acid. Both substances are classified as skin and eye corrosive. This is further proven in the supporting study for acute oral toxicity with a orthophosphoric acid where the animals developed strong chemical burns of the mucosal membranes in the stomach.Clinical signs of respiratory distress were observed during short term and long term inhalation toxicity studies with the read across substances BF3 or BF3 dihydrate, even at low concentrations.
Taking
the acute inhalation results of the read across substances (see IUCLID
chapter 7.2.2) into account, it can be assumed that the test substance
will lead to respiratory irritation when inhaled.
Effects on skin irritation/corrosion: corrosive
Effects on eye irritation: corrosive
Effects on respiratory irritation: irritating
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available data are considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance needs to be classified and labelled as corrosive to eye and skin (R35 Causes severe burns) and irritant to the respiratory tract (R37 Irritating to respiratory system) under Directive 67/548/EEC, as amended for the 31st time in Directive 2009/2/EC.
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available data are considered reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance needs to be classified and labelled as corrosive to eye and skin (H314 Causes severe skin burns and eye damage) and as irritant to the respiratory tract (H335 May cause respiratory irritation) under Regulation (EC) No 1272/2008, as amended for the sixth time in Regulation EC No 605/2014.
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).
