Description of key information
The highest log Koc value (3.55) determined according to the OECD testing Guideline 121 was used in the Chemical Safety Assessment.
Key value for chemical safety assessment
- Koc at 20 °C:
- 3 548
Additional information
A GLP study was conducted to determine the adsorption coefficient of 4,4'-lsopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, esters with acrylic acid according to OECD Guideline 121, HPLC method.
Under the test conditions, the chromatogram of 4,4'-lsopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, esters with acrylic acid gave four peaks with log Koc values of 1.422 ± 0.001 (peak 1: 0.690 mAU*min), 1.812 ± 0.003 (peak 2: 0.268 mAU*min), 2.605 ± 0.001 (peak 3: 7.750 mAU*min) and 3.550 ± 0.002 (peak 4: 20.058 mAU*min) at 25 ± 1 ºC.
