Description of key information

The results of an OECD 121 test indicated that the log Koc of  1,1,3,3-tetramethylbutyl peroxy-2-ethylhexanoate is 4.0.

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

The adsorption coefficient (Koc) of 1,1,3,3-tetramethylbutyl peroxy-2-ethylhexanoate was estimated using the High Performance Liquid Chromatography (HPLC) method. The Koc test was performed in accordance with the OECD guideline 121 without modification. The data on Koc can be used to predict the potential of the test substance to partition to soil, sediment or sewage sludge. The average measured log Koc value for 1,1,3,3-tetramethylbutyl peroxy-2-ethylhexanoate as calculated from the test was 4.0.

[LogKoc: 4.0]
