Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The test substance is a complex mixture of components containing the reaction products emerging from the addition of 3 mol behenic acid to 1 mol of polyglycerol. It was found to be of low aquatic toxicity but of moderate biodegradability and of high adsorptivity. Due to its lacking ready biodegradability and its high potential to partition to soil, long-term exposure of terrestrial organisms is possible. According to ECHAs “Guidance on information requirements and chemical safety assessment, Chapter R.7c: Endpoint specific guidance” and the REACH regulation EC 1907/2006, long-term terrestrial studies should be considered for substances holding adsorptive properties.

The Average Molecular Weight (Mw) was determined to amount to 2300 g/mol (characterization study BASF SE 11L00395, 2012). The log Kow value of a representative structure was calculated to be approx. 27.6 using EPI Win v4.10 and its Average Maximum Diameter (Diam Max-Average) was calculated to be 45.3 nm using Catalogic BCF base-line model v2.05 (both BASF SE, 2013).

These physico-chemical properties indicate a hindered absorption and distribution into terrestrial organisms due to the inability to pass cell membranes. Therefore, the molecules are unlikely to be bioavailable to terrestrial organisms just like plants and earthworms. Based on the physico-chemical properties of the substance and its negligible toxicity to aquatic organisms, further studies investigating the terrestrial toxicity were not considered necessary.
