Description of key information
Determination of the Adsorption coefficient of the isomer p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline (496981)
(GLP compliant study based on the Commission Regulation (EC) No 440/2008, C19, 2008 and OECD No. 121, 2001)
Key value for chemical safety assessment
- Koc at 20 °C:
- 84
Additional information
The Adsorption coefficient of the isomer p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline was determined according to OCDE and EC Guidelines, which gives internationally accepted methods.
The HPLC method using soil-adsorption-reference data was applied for the determination of the adsorption coefficient (Koc) of the test substance. The Koc and log Koc value of the test substance and impurities with peak areas > 1% at neutral pH was :
| Koc | log Koc | Area (%) | |
| Test substance | 84 | 1.93 | 96 |
| Impurity III | 50 | 1.7 | 1.1 |
This study is classified acceptable and satisfies the guideline requirements for Adsorption coefficient studies. It is considered that the same values apply for the m-isomer (=substance described in section 1)
[LogKoc: 1.93]
