Description of key information
Determination of hydrolysis of Linseed oil, epoxidised was not considered to be possible based on read-across to an attempted OECD 111 study on soybean oil, epoxidised. The attempted study was not technically feasible due to its negligible water solubility and the fact that the test material found in solution represented only the lower molecular weight range of the test material components, and thus did not address the more abundant, higher molecular weight fraction of the test material.
According to REACH guidelines, a stability study is not required as Linseed oil, epoxidised is considered to be readily biodegradable.
Linseed oil, epoxidised is considered to be readily biodegradable based on a read-across study conducted on TK 11278 (otherwise known as Reoplast 39 or epoxidised soybean oil) (Schulthess, 1988).
The partition coefficient (log Kow) of Linseed oil, epoxidised was shown to be >6.2. A bioaccumulation study is not considered necessary however, given that uptake into fish is expected to be hindered by the large molecular size. If taken up by fish, these carboxylate ester-containing substances are expected to be readily metabolized and excreted. Thus, the bioaccumulation potential is expected to be much lower than predicted from log Kow alone.
Linseed oil, epoxidised was determined to have a log Kow value of greater than 5.7 and therefore cannot be expected to have a low adsorption potential to soil. According to KOCWIN the estimated Log Koc of Linseed oil, epoxidised was between Log Koc 13.56 (Koc Estimate from MCI) and Log Koc 12.15 (Koc Estimate from Log Kow).
Additional information
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.
