- other: not oxidising
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Phosphinic acid is well known to be a strong reducing agent. Moreover its classification according to regulation on transport of dangerous goods is yet established (Class 8, UN N°3264: corrosive liquid, acidic, inorganic) and confirms that phosphinic acid 60% is unable to show an exothermic reaction with a fuel.
- Executive summary:
Expert statement (as cited in the report):
As stated Annex VII, point 7.13 of the REACH regulation No 1907/2006 “This test need not to be performed when examination of the structural formula establishes that the substance is incapable of reacting exothermically with a combustible material.”
According to the chemical structure and the fact that it is in solution in water as well as the strong reduction potential of the solid test substance it is possible to exclude beyond reasonable doubt that this substance has oxidising properties.
The test substance is classified in the class 8 N° UN 3264 (corrosive liquid, acidic, inorganic) according to UN regulation on transport of dangerous goods confirming the conclusion based on the chemical structure regarding the absence of oxidising properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
