Description of key information

No determination was possible by Method 111 of the OECD Guidelines for Testing of Chemicals due to the negligible solubility of soybean oil, epoxidised in water, 1.36 x 10-3 g/L of solution at 20.0 ± 0.5 °C. Secondly and more critically, the test material found in solution during the water solubility study represented only the lower molecular weight range of the test material components. Therefore working at half this water solubility value, the maximum concentration permitted by the method guideline, was not applicable since the value does not address the more abundant, higher molecular weight fraction of the test material.

Read across to a study result from an investigation using a similar material is justified for members of the Epoxidised Oils and Derivatives group. Four epoxidised oils and esters (linseed, soybean,9-octadecanoate propylene glycol ester and  2-ethylhexyl tallate ester ETP) have been identified as sharing common structural and functional similarities, recognised in an OECD SIDS review as a single category, and therefore justifying read-across between data for different members of the group. The C14-C22, 2-ethylhexylesters are listed as similar products on the market to ETP based on fatty acids from other naturally occurring fatty acids. Consequently data sharing between ESBO epoxidised soybean oil, ELO epoxidised Linseed oil and ETP epoxidised 2-ethylhexyl tallate and fatty acids, C14-C22, 2-ethylhexylesters, epoxidised is commonly utilised in the preparation of this dossier.

Read-across bridges are used for members of the EOD group where appropriate, is justified based on similar toxicity profiles and structural and functional similarities.

According to REACH guidelines a Stability study is not required as Soybean Oil, epoxidised is considered to be readily biodegradable ( Schulthess A.V., 1988).
