Conclusion on classification

By analogy with cerium and iron oxide isostearate (active matter of DPX10), iron oxide isostearate (active matter of DPX13) is considered as not readily biodegradable. Based on the assessment performed on the organic isostearate part and on the inorganic iron part, iron oxide isostearate is considered to pose no risk to aquatic organisms from its bioconcentration and biomagnification properties. Short-term tests performed on the three trophic levels (i.e. fish, daphnids, algae) with iron oxide isostearate and/or its analogue (cerium and iron oxide isostearate) do not reveal any acute toxicity up to and including the water solubility limit. Furthermore, chronic data on the analogue, cerium and iron oxide isostearate, are available on the three species and indicate the substance, and by analogy iron oxide isostearate, has no adverse effect on growth of juvenile fish, on survival and reproduction of daphnids, and on algal growth rate up to and including the water solubility limit into the test medium. As a result, iron oxide isostearate is not classified regarding its environmental impacts under the criteria of CLP.
