  • Patent number: 11478498
    Abstract: An aqueous formulation for topical application to the skin comprising water, a water-miscible organic solvent, and benzoyl peroxide, wherein the concentration of the organic solvent is sufficient to provide a stable suspension of benzoyl peroxide in the aqueous formulation without the inclusion of a surfactant in the formulation, wherein the ratio of concentrations of water and organic solvent in the formulation is sufficient to maintain the benzoyl peroxide in saturated solubility in the formulation following application to the skin, and wherein the concentration of benzoyl peroxide in the formulation is less than 5.0% and at least 1.0% w/w. The formulation may further contain a chemical compound in addition to benzoyl peroxide that is effective in the treatment of acne. The aqueous formulations of the invention are useful in the treatment of acne and acne rosacea.

  • Patent number: 10166235
    Abstract: The solubility of kinetin and/or of zeatin is increased when either or both are combined in a formulation that includes a polyoxyalkylene-n-glycerol dicarboxylate component and a fatty acid component. These two components provide a synergistic increase in the solubility of kinetin and/or zeatin that is greater than that which would be expected based on the solubility of kinetin and zeatin in the individual components.
