- Conclusions:
- Significant variations in the estimated logKOC are identified, as the values vary between 4.0 and up to 7.3. The definite values may not be fully reliable, but they all indicate a high adsorption potential.
Therefore, the overall adsorption potential of glycerol monobehenate is expected to be high with a
logKOC >4.0.
The available information together comprises sufficient reliable data to conclude a logKOC of the
substance > 4.0 based on a weight-of-Evidence approach. The information provides sufficient weight of evidence leading to an endpoint conclusion in accordance with Annex XI, 1.2, of Regulation (EC) No 1907/2006. - Executive summary:
Glycerol monobehenate is a mono constituent substance with a purity of 80-90%. Data on KOC are not available for Glycerol monobehenate.
No test data on adsorption-desorption behaviour of the substance and similar substances such as mono-, di- and triglycerides, fatty acids, are available. Therefore, various QSAR models were applied to estimate the logKOC. Three set of QSAR calculations were carried out using SPARC, EpiSuite, QSAR VEGA. In addition, a read-across to alcohol ethoxylates was carried out, with the argument that both substances are composed of a hydrophobic alkyl chain and then a hydrophilic group either being a number of ethoxylate-units (for alcohol ethoxylate) or the glyceryl (for the glycerol monobehenate).
Significant variations in the estimated logKOC are identified, as the values vary between 4.0 and up to 7.3. The definite values may not be fully reliable, but they all indicate a high adsorption potential.

Description of key information
Glycerol monobehenate is a mono constituent substance with a purity of 80-90%. Data on KOC are not
available for Glycerol monobehenate.
No test data on adsorption-desorption behaviour of the substance and similar substances such as
mono-, di- and triglycerides, fatty acids, are available. Therefore, various QSAR models were applied to
estimate the logKOC. Three set of QSAR calculations were carried out using SPARC, EpiSuite, QSAR
VEGA. In addition, a read-across to alcohol ethoxylates was carried out, with the argument that both
substances are composed of a hydrophobic alkyl chain and then a hydrophilic group either being a
number of ethoxylate-units (for alcohol ethoxylate) or the glyceryl (for the glycerol monobehenate).
Significant variations in the estimated logKOC are identified, as the values vary between 4.0 and up to
7.3. The definite values may not be fully reliable, but they all indicate a high adsorption potential.
Therefore, the overall adsorption potential of glycerol monobehenate is expected to be high with a
logKOC >4.0.
The available information together comprises sufficient reliable data to conclude a logKOC of the
substance > 4.0 based on a weight-of-Evidence approach. The information provides sufficient weight of
evidence leading to an endpoint conclusion in accordance with Annex XI, 1.2, of Regulation (EC) No
1907/2006.
