The log POW for the substance was determined in an assessment according to OECD Guideline 117. Based on the analysis of structurally related substances with a known Log POW the relationship Log(K) / (Log POW) was established for a suitable HPLC set-up. From the capacity factor k measured for the test items under identical conditions its Log POW could be deduced.
Log POW values were determined for the the following constituents of the substance:
C16 alkyl-monoglucoside: 4.4
C18 alkyl-monoglucoside: 5.81

Description of key information
In a measurement of "Glucose, reaction products with alcohols C16 -18" according to Guideline OECD 117 the log Kow of two main components was determined to be
5.81 C18 alkyl-monoglucoside
4.4 C16 alkyl-monoglucoside
QSAR calculation of logKow with EPI, model KOWWIN (v1.68) resulted in:

5,84 |
Mono-C18-glucoside for comparison with measured value |
4,86 |
Mono-C16-glucoside for comparison with measured value |
4,91 |

3,93 |
Di-C16-glucoside |
-0,68 |
Tri-C16-glucoside |
0,30 |
Tri-C18-glucoside |
For Mono-C18-glucoside and Mono-C16-glucoside comparison between measured and QSAR-calculated logKow shows only small differences.
As a conclusion, the use of QSAR-calculated logKow values can be justified.
The calculation of a weighted-mean logKow with the two measured logKow (above) and four QSAR-calculated logKow for the four other main components results in:
logKow = 4.64 for "Glucose, reaction products with alcohols C16 -18"
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.64
- at the temperature of:
- 25 °C
