Conclusion on classification
Sinpine P is a multi-constituent substance. For a mixture, the acute effect loading level (typically expressed as the EL50) from aquatic tests using water-accomodated fractions (WAFs) may be used directly for classification. An acute daphnia study is available for Sinpine P which gave a 48h EL50 of 2.8 mg/L. Based on a valid algal inhibition study for the read-across substance Lime oxide, which has a similar composition to Sinpine P, the 72h ErL50 is estimated to be 15mg/L. Since all EL50 values are > 1mg/L, the substance is not classified for short-term hazards to the aquatic environment according to the CLP Regulation 1272/2008/EC.
Chronic aquatic toxicity data is only available for one trophic level (algae). Therefore, the long-term hazard has been assessed based on both:
a) The chronic aquatic toxicity data for algae (ErL10 = 11 mg/L, read-across substance) which results in no classification and
b) The acute aquatic toxicity data (daphnia EL50 = 2.8mg/L) and environmental fate data for the constituents of Sinpine P (readily biodegradable and log Kow range of 3.1 to 5.7.), which results in a chronic 2 classification for the substance because the majority of constituents have a log Kow > 4,
and classifying according to the most stringent outcome.
Thus it is concluded that the substance is classified Aquatic Chronic 2 (H411) according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.
Under the old DSD regulation the substance would be classified as R51/53 (harmful to aquatic organisms and may cause long-term adverse effects in the aquatic environment).
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.
