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, a polyethylene glycol ether of oleyl alcohol, preferably Oleth-2, and a polypropylene glycol ether of stearyl alcohol, preferably PPG-15 stearyl ether. 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.

Process and composition for microemulsion gel having bleaching and

An isopropyl alcohol gel having use as a rubbing composition and having antiseptic properties. The isopropyl alcohol gel of the present invention comprises a polymer, water, isopropyl alcohol and a polymer neutralizing agent. The polymer is dispersed in water to create a thick phase. The preferred polymer is a carbomer resin that forms a slightly gelatinous mass through hydration of the polymer. The selected amount of isopropyl alcohol is added by dispersion to the polymer-water phase. The mixture is allowed enough time to fully hydrate. A neutralizing agent is thereafter added to neutralize the activity of the polymer. The neutralizing agent is preferably tetrahydroxypropyl ethylenediamine. The resulting product is in homogenous heavy clear gel form.

In its preferred embodiment, the oil phase comprises a polyethylene glycol ether of isocetyl alcohol, preferably Isoceteth-20 (trademark), a polyethylene glycol ether of oleyl alcohol, preferably Oleth-2 (trademark), and 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.
