- Key result
- Conc. based on:
- test mat.
- Incubation duration:
- ca. 1 d
- Temp.:
- 20 °C
- Remarks on result:
- not determinable
- Conclusions:
- Water solubility of the test substance, Pigment Yellow 4, could not be determined because the test substance is insoluble in water.
- Executive summary:
On the basis of character of the test substance and the information from sponsor, the test substance is considered as insoluble in water.
Based on this information the study was not performed and the following Expert Statement is issued instead:
Water solubility of the test substance, Pigment Yellow 4, could not be determined because the test substance is insoluble in water.
Reference
Description of key information
Water solubility of the test substance, Pigment Yellow 4, could not be determined because the test substance is insoluble in water.
Key value for chemical safety assessment
- Water solubility:
- 0 µg/L
- at the temperature of:
- 20 °C
Additional information
Reasons for not performing the study
On the basis of character of the test substance and the information from sponsor, the test substance is considered as insoluble in water.
This claim was confirmed by spectrophotometric measurement of the test substance solution in water (100 mg/100 mL of water after one day of shaking at 30 °C and 1 day of incubation at 20°C). In the filtrate (syringe membrane filter (Nylon, 0.22 um)) was not found any absorbance in wave length 350-780 nm.
Thus the determination of Pigment Yellow 4 cannot be performed due to the character of the test substance, pigment is insoluble in water.
