Guideline:
EU Method A.8 (Partition Coefficient)
Deviations:
not specified
GLP compliance:
no
Type of method:
other: calculation (fragment method)
Partition coefficient type:

Specific details on test material used for the study:
Product designation: Monoazo Yellow TZ 2382
Identification: FAT 40224/C
Vers. 10/86 Op. 1/86
Type:
log Pow
Partition coefficient:
ca. -10.8
Remarks on result:
other: Calculated value
Conclusions:
The calculated partition coefficient of FAT 40224/C between n-octanol and aqueous phase is ca -10.8 (log Pow).
Executive summary:

In a study performed with FAT 40224/C according to EU Method A.8, the partition coefficient of the test substance between n-octanol and aqueous phase was determined. The preliminary test, performed by the shake flask procedure, has shown that the expected log Pow lies outside the range accessible by the shake flask method and therefore had to be calculated. The calculated partition coefficient of the test substance between n-octanol and aqueous phase is: ca -10.8 (log Pow).

Description of key information
