Conclusions:
log Pow of 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate): 11.03 at 25 °C
Executive summary:

The log Pow of 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) was determined according to OECD 117.

The log Pow versus log K values of the reference substances (Thymol, Naphthalene, Benzyl benzoate, Bibenzyl, 1 -Dodecanol and Tetradecanol) was plotted (R² = 0.985). The resulting equation was used to calculate the log Pow of the test substance: log Pow of 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate): 11.03 at 25 °C.

Description of key information

The octanol-water partition coefficients of constituents of 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) is 11.03 (HPLC method)

Key value for chemical safety assessment

Log Kow (Log Pow):
