- Conclusions:
- Interpretation of results (migrated information): soluble (1000-10000 mg/L)
The water solubility of TCPP has been deternined to be 1.08 g/L of solution at 20°C +/- 0.5°C. - Executive summary:
The water solubility of TCPP is 1.08 g/L at 20°C at pH 5.7. Determination was carried out according to the EU-method A.8, flask method. The mean concentration was taken from two samples and were within the +/-15 % criteria specified in Method A6.
The concentrations of the test material were determined by GC.
Reference
Range of concentrations found in the definitive test: 1.06 to 1.11 g/L The pH was in the range of 5.6 to 5.8. Results related to mean values.
| Sample Number | Time shaken at ca. 30°C (hours) | Time equilibrated at 20°C (hours) | Concentration (g/L) | pH |
| 1* | 24 | 24 | 0.944 | 5.1 |
| 2 | 48 | 24 | 1.06 | 5.8 |
| 3 | 72 | 24 | 1.11 | 5.6 |
*Sample 1 was not includedin the calculationof the mean or range of the final result as this sample may not have reached saturation in the shaking time allowed.
The mean concentration was therefore taken from samples 2 and 3 which were shown to be within the +/-15 % criteria specified in Method A6.
Description of key information
The water solubility of TCPP has been determined to be 1.08 g/L of (20°C; pH = 5.7). pH dependence is not expected based on the structure of the test item.
Key value for chemical safety assessment
- Water solubility:
- 1.08 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of TCPP is 1.08 g/L at 20°C at pH 5.7. Determination was carried out according to the EU-method A.8, flask method. The mean concentration was taken from two samples and were within the +/-15 % criteria specified in Method A6.
The concentrations of the test material were determined by GC as sum of TCPP constituents.
