Additional information
Conclusion on classification
Three short-term and two long-term toxicity studies are available on the read across substances, Coco TMAC, DDAC, C12-16 ADBAC and/or C16-18 and C18-unsatd. TMAC. Based on short-term tests, algae has been identified to be the most sensitive species with the lowest 72 h ErC50 value determined to be at 0.062 mg/L (nominal). Out of the long-term tests, Daphnia has been identified as the most sensitive species with the lowest NOEC value of 0.0068 mg/L. Therefore, based on the available results and considering that the substance is readily biodegradable with a low bioaccumulation potential, C12-14 TMAC requires classification as Aquatic Acute 1 and Aquatic Chronic 1; H410: Very toxic to aquatic life with long-lasting effects according to Regulation EC 1272/2008. M factors to be applied are 10 for acute and 1 for chronic toxicity.
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.
