This invention relates to novel water in oil emulsions. The emulsions of this invention are translucent water in oil emulsions comprising a water phase containing a humectant, an oil phase comprising petroleum jelly and the like and an emulsifying agent to give a water in oil emulsion; the aqueous phase having a refractive index in essentially the same range as the oil phase. The translucent water in oil of this invention have the same general appearance and feel of petroleum jelly and function like petroleum jelly but are superior thereto in the sense that when applied to skin will not only help prevent water from escaping therefrom or exist a barrier effect, but also, will allow water humectants and other moisturizers from the emulsion water phase to pass therethrough to contact the skin and to moisturize the skin. The compositions of this invention are useful as skin moisturizer compositions. They may be used as a carrier or vehicle for oil and water soluble topical drugs. They also may be used in the same general way as petrolatum (e.g. skin protectant agent, emollient, lubricant, etc.) |
