Ferric salts
Ferric chloride (FeCl3) is generally a known to be mild oxidising agent (O'Neil et al 2006). The oxidation potential of the ferric ion can be represented by the equilibrium formula for Fe(2+) => Fe3+ + e- (Pourbaix & Zoubov 1966).
Fe(2+) = Fe(3+) + e- Eo = 0.771 + 0.0591 ∙ Log [Fe3+] / [Fe2+]
A reliable screening test for oxidising properties conducted in accordance with UN method O.1 and with EU A.1 has demonstrated that the solid salt form of ferric sulphate gives a negative response. In conclusion ferric salts can be regarded as non-oxidising in the context of the criteria by which this hazard is defined for regulatory purposes (Baltussen 2010 study 492704) as long as the related anion in comparably inert as the sulphate, which can be assumed for chloride as the chlorine is already in the lowest possible oxidation state. This conclusion applies for all ferric salts in the category as both the sulphate and the chloride counterions are considered comparably inert. It confirms that in the context of physicochemical hazards, ferric salts do not exhibit relevant oxidising properties.
Justification for classification or non-classification
The following statements base on DSD, the Commission Directive 2001/59/EC (28th ATP of Council Directive 67/548/EEC), and CLP (5th ATP of Regulation (EC) No 1272/2008 of the European Parliament and of the Council) as implementation of UN-GHS in the EU:
The submission item is considered non-oxidizing on the basis of its chemical nature and composition. Ferric (Fe+3) kation is however a mild oxidising agent not sufficient for classification. This is confirmed by a guideline study for the ferric sulphate, which was found non-oxidizing according to the applicable standards.
