Development and Evaluation of Stability of a Gel Formulation Containing the Monoterpene Borneol
Table 1
Results of evaluation of the preliminary stability of borneol gel 5% before and after the freeze-thaw cycle.
| Sample | Appearance | pH | Conductivity | Centrifugation |
| BG5% before | Homogeneous, transparent, colorless | 3.95 ± 0.01 | 186.15 ± 0.35 mV | No noticeable instability in the formulation. | BG5% after | Homogeneous, transparent, colorless | 3.83 ± 0.03 | 171.3 ± 1.27 mV | No noticeable instability in the formulation. |
