This controlled release of benzoyl peroxide to skin can alter the dose relation that exists between efficacy and skin irritation.
Therefore, the safety level of synthesis of benzoyl peroxide can be significantly improved by using Na 2 CO 3 solution.
Thus, solution formulations of benzoyl peroxide in pharmaceutically acceptable solvents are unlikely to show good stability; however, suspension formulations should be reasonably stable if the vehicle is selected to provide low benzoyl peroxide solubility.
Probably, hydrogen peroxide is an intermediate.
These studies confirm the potential of benzoyl peroxide incorporation into submicron emulsion gel and the stability of this formulation.
The efficiency of the peroxide as cross-linking agent seems to be dependent on the concentration of peroxide.
