Key value for chemical safety assessment
Additional information
One study on fish toxicity is available for Heptanoic acid, ester with 2,2-dimethyl-1,3-propanediol (CAS No. 68855-18-5).
The key study conducted with Heptanoic acid, ester with 2,2-dimethyl-1,3-propanediol (CAS No. 68855-18-5) was performed, according to OECD Guideline 203 and GLP, in a semi-static system, using Oncorhynchus mykiss as test organism (Parr, 2012). During 96 hours, the fish were exposed to the nominal test concentrations of 100% v/v, corresponding to a measured concentration of 0.086 mg/L. This was the highest attainable concentration, due to the poor solubility of the test substance. The test solutions were prepared using a solvent, and undissolved test material was removed by filtration. No mortality occurred during the study, and the LC50 (96 h) was reported to be > 0.086 mg/L.
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.
