Additional information
QSAR-disclaimer
In Article 13 of Regulation (EC) No 1907/2006, it is laid down that information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI (of the same Regulation) are met. Furthermore according to Article 25 of the same Regulation testing on vertebrate animals shall be undertaken only as a last resort.
According to Annex XI of Regulation (EC) No 1907/2006 (Q)SAR results can be used if (1) the scientific validity of the (Q)SAR model has been established, (2) the substance falls within the applicability domain of the (Q)SAR model, (3) the results are adequate for the purpose of classification and labeling and/or risk assessment and (4) adequate and reliable documentation of the applied method is provided.
For the assessment of 2 -Propenoic acid 4 - [[(4 -benzoylphenoxy)carbonyl]oxy]butyl ester (Q)Sar results were used for Adsorption/Desorption. The criteria listed in Annex XI of Regulation (EC) No 1907/2006 are considered to be adequately fulfilled and there the endpoint(s) sufficiently covered and suitable for risk assessment.
Therefore further experimental studies on Adsorption/Desorption are not provided.
The Koc value is based on the Epiwin calculation of logKow. The log Kow for Propenoic acid 4 -[[(4 -benzoylphenoxy)carbonyl]oxy]butyl ester has been measured in a BASF Study (IUCLID Section 4.7) according to EU method A.8 (Partition coefficient). The MCI calculation is based on results from other substances.
