Acute studies are available for fish, Daphnia and algae based on read across. The lowest acute effects were observed at 1.6 mg/L, for Daphnia.
Conclusion on classification
Under CLP legislation there would be no environmental classification for either the rosin or fatty acid components of Distilled tall oil, magnesium salt.
There are a wide range of ecotoxicity results for the rosin component of the substance. The lowest EC50 is 1.6 mg/L. As this is >1 mg/L no acute environmental classification is assigned to the rosin component of Fatty acids, tall oil, magnesium salts. A chronic environmental classification is not assigned to the rosin component of the substance as although the lowest EC50 result is between 1 and 10 mg/L the rosin component is readily biodegradable and a measured BCF study for resin acids determined BCF values <500.
The lowest EL50 result for the fatty acid component of Distilled tall oil, magnesium salt is 13 mg/L. As this is >1 mg/L no acute environmental classification is assigned to the fatty acid component. A chronic environmental classification is not assigned to the fatty acid component of the substance as although the lowest EC50 result is between 10 and 100 mg/L the fatty acid component is readily biodegradable and a calculated Log Kow values indicate that the log Kow value is <4.
Based on the available information neither the rosin or fatty acid component of Distilled tall oil, magnesium salt would be classified for the environment, and neither is classified by the Lead Registrant of these substances. Therefore Distilled tall oil, magnesium salt is not classified for the environment under the CLP regulation.
Under the DSD regulation there would be no environmental classification for either the rosin or fatty acid components of Distilled tall oil, magnesium salt.
No acute classification would be assigned to the rosin component as the lowest EC50 value is >1 mg/L. No chronic environmental classification would be assigned as although the lowest EC50 is between 1 and 10 mg/L the rosin component is considered to be readily biodegradable. Measured BCFs are available for ten resin acids ranging from <25 - 129, of these nine have BCF values <100. Therefore it is considered that overall the rosin component has low potential for bioaccumulation. A chronic classification is not therefore applicable for the rosin component.
No acute classification is assigned to the fatty acid component as the lowest EL50 value is >1 mg/L. No chronic classification is assigned as although the lowest EL50 is between 10 and 100 mg/L the fatty acid component is readily biodegradable.
Based on the available information neither the rosin or fatty acid component of Distilled tall oil, magnesium salt would be classified for the environment, and neither is classified by the Lead Registrant of these substances. Therefore Distilled tall oil, magnesium salt is not classified for the environment under the DSD regulation.
For poorly water soluble substances, such as Distilled tall oil, magnesium salt, a precautionary classification of Chronic Category 4 (CLP) or R53 (DSD) may be applied. However, this is not appropriate here as Distilled tall oil, magnesium salt is readily biodegradable.
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.
