Materials and methods

Test guideline
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
Principles of method if other than guideline:
An estimation of their log Pow was nevertheless carried out with an HPLC method adapted from the OECD 117 guideline. The results obtained can only be considered as estimates because all the constituents of these complex substances were probably not be detected with the detectors used with HPLC in the OECD 117 method.
GLP compliance:
yes
Type of method:
HPLC method
Partition coefficient type:
octanol-water

Test material

Constituent 1
Reference substance name:
Avena Sativa leaf/stem extract
EC Number:
948-064-7
IUPAC Name:
