A microemulsion gel having antiseptic and bleaching properties is prepared from the combination of a water phase comprising water and propylene glycol with an oil phase generally comprising one or more surfactants, an emollient, and an oil. In its preferred embodiment, the oil phase comprises a polyethylene glycol ether of isocetyl alcohol, preferably Isoceteth-20 (trademark), a polyethylen glycol ether of oleyl alcohol, preferably Oleth-2 (trademark), a polypropylene glycol ether of stearyl alcohol, preferably PPG-15 stearyl ether (trademark). The water phase optionally includes sorbitol and the oil of the oil phase may be mineral oil. The water and oil phases are heated independently then combined and mixed. Hydrogen peroxide is subsequently added to the composition, and the combination is cooled and allowed to stand until a gel is formed. A fragrance may be added as desired. |
