Description of key information

In the key study the ready biodegradability of the test item 2 -decyltetradecanoic acid was determined with a non-adapted activated sludge over a test period of 35 days in the Modified Sturm Test according to OECD 301 B.

Four of six replicates reached a mean of 63 % biodegradation after 28 days. Therefore under the test conditions the test item 2-decyltetradecanoic acid is classified as readily biodegradable, but failing the 10-day-window.

Estimated BCF from regression-based method and BCF from Arnot-Gobas method values of 3.162 (log BCF = 0.5) and 3.702 (log BCF 0.568 - upper trophic) respectively indicate a low bioaccumulation potential of 2 -decyltetradecanoic acid.

The Koc of the component 2 -decyltetradecanoic acid was estimated with the program US EPA EPI Suite (v 4.00), program component KOCWIN. Using a correlation based on molecular connectivity index, the log Koc was determined to be 5.6052 (Koc = 402900 L/kg). Using a correlation based on Kow, the log Koc was 6.1406 (Koc = 1382000 L/kg).

The McCall classification scheme classifies the substances as medium soil mobility potential (Koc 150 -500).
