Adsorption / desorption
No experimental data are available for this endpoint, which is regarded to be mandatory under REACH. However, a scientifically accepted calculation method was used by Chemservice S.A. (2011) to fulfil this data requirement as followed: The prediction for soil adsorption property of the test substance was determined by the computer program KOCWIN v2.00 (EPIWIN software) by US-EPA. The program estimates the organic-normalized sorption coefficient for soil, which is designated as Koc. The following two models are used: the Salbjic molecular connectivity (MCI) method as well as the traditional method which is based on the logPow value of the substance. The MCI method is taken more seriously into account, due to the fact that is includes improved correction factors, resulting in a Koc value of 491.1 L/kg for the chemical compound. The traditional method gives a value of 26.06 L/kg. No GLP criteria are applicable for the usage of this tool, but due to the fact that it is a scientifically accepted calculation method the estimations performed are reliable with restrictions and can be used for the chemical safety assessment.
Henry´s Law constant
This information is not mandatory under REACH, however, it is possible to predict the distribution between aqueous solution and air for the test substance with the help of the computer program HENRYWIN v3.20 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). The program calculates the Henry´s Law Constant based on the Bond Method of 0.0000000237 Pa*m³/mol (2.37 E-008 Pa*m³/mol) at an ambient temperature of 25 °C. The Group Method shows an "Incomplete Result".
