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.

Values are mean ± standard deviation.
