- Key result
- Type:
- log Pow
- Partition coefficient:
- 2.2
- Temp.:
- 25 °C
- pH:
- ca. 6
- Conclusions:
- The log pow of Ethylphthalyl ethyl glycolate was determined using the HPLC method according to OECD 117. The partitioning coefficient of the test item was stated as 2.2 at 25 ± 0.5 °C and a pH of ca. 6.
Reference
Using the correlation log k / log POW, the log POW of the test item Ethylphthalyl ethyl glycolate was calculated as 2.2 ± 0.0 (mean ± standard deviation) at 25 ± 0.5 °C and a pH of ca. 6.
The validity criteria and results are presented in the following table:
