Abstract
A W/O type emulsified composition comprising an oil phase containing ethyl cellulose and a solvent capable of swelling ethyl cellulose and a water phase containing a water soluble polymer(s) emulsified as a water-in-oil type (W/O type) emulsion. A W/O type emulsified composition comprising an oil phase containing ethyl cellulose and a solvent capable of swelling ethyl cellulose and a water phase containing a polyion complex comprising cationized cellulose and sodium hyaluronate emulsified as a water-in-oil type (W/O type) emulsion.
Claims10
A water-in-oil (W/O) emulsified composition comprising an oil phase containing ethyl cellulose and an ethyl cellulose swelling solvent, and a water phase containing a water soluble polymer(s) which has been emulsified without a surfactant.
A water in oil (W/O) emulsified composition comprising an oil phase containing ethyl cellulose and an ethyl cellulose swelling solvent, and a water phase containing a polyion complex comprising cationized cellulose and sodium hyaluronate which has been emulsified without a surfactant.
A method of manufacturing a water in oil (W/O) emulsified composition in which an oil phase containing ethyl cellulose is prepared by using an ethyl cellulose swelling solvent and then said oil phase and a water phase containing a water soluble polymer are stirred without using a surfactant to emulsify them as a water-in-oil (W/O) emulsion.
A method of manufacturing a water in oil (W/O) emulsified composition in which an oil phase containing ethyl cellulose is prepared by using an ethyl cellulose swelling solvent and then said oil phase and a water phase containing a polyion complex comprising cationized cellulose and sodium hyaluronate are stirred without using a surfactant to emulsify them as a water-in-oil (W/O) emulsion.
