- Details on results:
- In the present study, the n-octanol solubility of DIPENTAERYTHRITYL
HEXAHYDROXYSTEARATE/STEARATE/ROSINATE was determined to be about 354 g/I.
The water solubility of the test article was stated to be 0.3 mg/I ± 0.1 mg/I.
Basing on these data, the partition coefficient, log Pow, of DIPENTAERYTHRITYL
HEXAHYDROXYSTEARATE/STEARATE/ROSINATE was calculated to be:
log Pow = log (354 x 10^3 mg/I / 0.3 mg/I) = 6.1 - Conclusions:
- The partition coefficient, log Pow, of DIPENTAERYTHRITYL HEXAHYDROXYSTEARATE/
STEARATE/ROSINATE was estimated to be:
log Pow = 6.1 - Executive summary:
In the present study the n-octanol/water partition coefficient of DIPENTAERYTHRITYL
HEXAHYDROXYSTEARATE/STEARATE/ROSINATE was determined using a calculation
method according to EEC directive 92/69. The solubility of the test article in water and in noctanol
indicates a partition coefficient above 6. Therefore an experimental method
according to OECD Guidelines 107 or Guidelines 117 could not be applied and the partition
coefficient of DIPENTAERYTHR汀YL HEXAHYDROXYSTEARATE/STEARATE/
ROSINATE was estimated using the solubility data in n-octanol and in water. Concerning solubility in water it is referred to the respective study. The solubility in n-octanol was determined to be 353.65 g/l.
The partition coefficient, log Pow, of DIPENTAERYTHRITYL HEXAHYDROXYSTEARATE/
STEARATE/ROSINATE was estimated to be:
log Pow = 6.1
