Results and discussion
- Results:
- 6.2 Chemical Stability
The storage data presented in Table 2 for the stability of the active substance show no significant change in active substance content after storage with hexahydrotriazine remaining >98% of initial.
The pH characteristics showed no marked change over the storage period (Table 3).
6.3 Physical Stability
6.3. l The product showed no change in appearance over the storage period, remaining as a clear liquid with no foreign matter present (Table 1 ).
6.3.2 The product showed excellent cold stability, as shown by the freeze/thaw data presented in Tables 1 to 4 and the 7 days at 0°C data in Table 6.
These results indicate that the product would give satisfactory chemical and physical properties under use conditions.
6.4 Packaging
The data given in Table 5 show the HDPE packs to remain in good condition throughout the test, with no evidence of product leakage or penetration. - Transformation products:
- no
