Additional information
Category approach and aquatic toxicity
The substance being Registered in this particular dossier is one of a series of chemically similar materials each of which is composed of a closely related series of alkylated phenol species. For further details on the Category, see section 13. The data for other members of the category can be used to complete the hazard characterisation for the Registration material where substance-specific data are lacking. The majority of aquatic testing is conducted using Water Accommodated Fractions or methods where the effects of the presence of refined base oil in some category member samples would be minimised. However, for the derivation of PNECs, the presence/absence of the highly refined base oil is taken into account; the Registration material does not comprise as a constituent the base oil, but all toxicology testing has been carried out with oil present, hence the end results and PNECs are adjusted to take account of this and end up with values relevant to the active ingredient of this Registration material.
Conclusion on classification
Based upon the results of the key studies for fish, aquatic invertebrates and algae the registered substance does not meet the criteria for acute aquatic toxicity classification according to 67/548/EEC or EC Regulation 1272/2008. As it shows no toxicity at the limits of solubility, does not readily biodegrade, and has only an in vitro/experimental BCF study value rather than a whole fish result, and no chronic NOECs, it is considered that the material should not be classified for the environment. Nevertheless, due to the missing information the substance is classified in a precautionary approach as H413.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
