Description of key information

The key study was performed in order to estimate the adsorption coefficient on soil and sewage sludge of 1,2,4 -Benzenetricarboxylic acid, decyl octyl ester (CAS No. 67989 -23 -5) / 1,2,4 -Benzenetricarboxylic acid, mixed decyl and octyl triesters (CAS No. 90218 -76 -1) using the HPLC-method according to OECD Guideline for the Testing of Chemicals No. 121. The log KOC is estimated to be > 5.67. Also in another study according to OECD 121 a similar value of > 5.63 was found. These values indicate that the test item will be environmentally immobile.

Additional information

The key study was performed in order to estimate the adsorption coefficient on soil and sewage sludge of 1,2,4 -Benzenetricarboxylic acid, decyl octyl ester (CAS No. 67989 -23 -5) / 1,2,4 -Benzenetricarboxylic acid, mixed decyl and octyl triesters (CAS No. 90218 -76 -1) using the HPLC-method according to OECD Guideline for the Testing of Chemicals No. 121. The log KOC is estimated to be > 5.67. Also in a supporting study conducted according to OECD 121 a similar value of > 5.63 was found. These values indicate that the test item will be environmentally immobile.
