Details on results:
The partition coefficient (n-octanol/water) of Nonylphenol,ethoxylated provided
by Shenzhen Kunqi Xinhua Technology Co., Ltd. was tested. The test was conducted
under stable laboratory condition. The partition coefficient(n-octanol/water) of test
item was determined according to the Guidelines for the Testing of Chemicals 117
Partition Coefficient (n-octanol/water), High Performance Liquid Chromatography
(HPLC) Method(STATE ENVIRONMENTAL PROTECTION ADMINISTARTION
OF CHINA 2004).
The partition coefficient(n-octanol/water)of the test item log Pow is 3.70
(estimated) at 25℃
