Description of key information

The adsorption coefficient on soil and on sewage sludge (Koc) of decamethylenediamine was determined according to OECD guideline 121 [2001] and EU test method C.19 [2008]. The result was log Koc = 5.1 (Koc = 125893) at pH 7.5 and 24.0-24.9 °C, indicating "very high" sorption potential (Blume scale). The test substance was not eluted when tested without buffer.

Key value for chemical safety assessment
