  • Composition and method for the treatment of acne
    Patent number: 4361584
    Abstract: Compositions containing organic peroxides are effective for the treatment of acne. Decomposition of the organic paroxide during storage is prevented by the incorporation of glycerol, which is sufficiently effective so that decomposition is prevented even in those peroxides which are so unstable as to be explosive.

  • Stabilized benzoyl peroxide compositions
    Patent number: 4350681
    Abstract: Benzoyl peroxide dispersed in an aqueous medium is stabilized by the presence of glycerol. Where the composition includes a finely dispersed and mild abrasive, together with a wetting agent and a thickener, the composition is suitable for use as a toothpaste. Where the composition includes a suitably large quantity of wetting agent and an appropriate soft abrasive, the composition is effective as a body scrub in preparation for surgery.
