Additional information
Due to the low water solubility of the substance, aquatic ecotoxicity testing, and thus PNEC derivations, were based on Water Accommodated Fractions (WAFs) of nominal concentrations of the Registration substance and the relevant read-across analogue material.
No PNECs were derived for the air compartment as the physical-chemical properties of the substance (very low V.P) dictate that this is not a relevant compartment for the registration substance.
Conclusion on classification
Registration substance EC 903-162 -9 showed no evidence of toxicity in any of the acute aquatic toxicity studies when tested as a water accomodated fraction, which was considered the most reliable and environmentally relevant method of testing. In light of this data the substance does not require classification for acute aquatic toxicity in accordance with Regulation (EC) No 1272/2008.
However, the CLP regulation also states that a safety net Chronic Aquatic toxicity, Category 4 classification should be applied when:
"Cases when data do not allow classification under the above criteria but there are nevertheless some grounds for concern. This includes, for example, poorly soluble substances for which no acute toxicity is recorded at levels up to the water solubility (note 4), and which are not rapidly degradable in accordance with section 4.1.2.9.5 and have an experimentally determined BCF = 500 (or, if absent, a log K ow = 4), indicating a potential to bioaccumulate, which will be classified in this category unless other scientific evidence exists showing classification to be unnecessary. Such evidence includes chronic toxicity NOECs > water solubility or > 1 mg/l, or other evidence of rapid degradation in the environment than the ones provided by any of the methods listed in section 4.1.2.9.5.
Note 4:
‘No acute toxicity’ is taken to mean that the L(E)C 50 (s) is/are above the water solubility. Also for poorly soluble substances, (water solubility < 1 mg/l), where there is evidence that the acute test does not provide a true measure of the intrinsic toxicity. "
While it is considered that for the notification substance, the B criterion is not met, based on properties of the chemistry (MW range) and modelled BCF values generated for main components, the other criteria for this Chronic Category 4 classifiation are met. As there are no experimental data to confirm bioaccumulation potential, a precautionary position is adopted and the safety net classification is applied.
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).
