Reference
Test 1
1 mL double distilled water was added to 1.02 g of the test substance. The mixture became warm. After stirring for 30 minutes at 20.2 ± 0.6 °C, the mixture was a light yellow gel with the stirring bar fixed in. After 18.8 hours, an extra volume of 9 mL double distilled water was added and an extra stirring bar. After 1 hour stirring at 20.2 ± 0.6 °C, no undissolved test substance was observed (nominal concentration 0.1x10³ g/L). The pH of the water mixture was 11.9.
Test 2
1 mL double distilled water was added to 0.53 g of the test substance and stirred for 30 minutes at 20.2 ± 0.6 °C (nominal concentration 0.5x10³ g/L). After the stirring period, the mixture was still clear. The pH of water mixture was 12.6.
Test 3
1 mL double distilled water was added to 1.00 g of the test substance (nominal concentration 1.0×10³ g/L). The mixture became warm and was a light yellow viscous liquid. After stirring for 30 minutes at 20.2 ± 0.6 °C, the mixture was a light yellow gel with the stirring bar fixed in.
Conclusion
After the stirring period, the test sample from test 2 was clear and no undissolved test substance was observed. From this, it was concluded that the water solubility of Penta ethylene hexamine at 20 °C was > 0.5x10³ g/L. The pH of the aqueous sample was 12.6.
Description of key information
The water solubility of the test substance at 20 °C is > 500 g/L. The pH of the aqueous sample was 12.6.
Key value for chemical safety assessment
