Problems solved by technology

[0002] The well-known vitamin E is a fat-soluble vitamin and an important antioxidant. It is soluble in organic solvents such as ethanol. Vitamin E can promote human metabolism, enhance body endurance, improve immunity, and protect biofilms from peroxidation. It plays the role of improving skin blood circulation, enhancing skin cell vitality and delaying aging. Without it, it will cause dry skin, rough skin, excessive aging and other adverse consequences.
In addition, vitamin E has many benefits to the human body. It has a good curative effect on skin care and beauty, and has a wide range of effects on skin diseases. Appropriate application of vitamin E can assist in the treatment of vitiligo, but vitamin E is unstable and easily affected by air. , light, heat, and metal ions catalyze and lose biological activity. In addition, vitamin E is highly fat-soluble and almost insoluble in water. The bioavailability of its common preparations is not high, and its application is limited. So how to improve the biological activity of vitamin E for external use? Utilization and enhancing its curative effect have always been technical problems to be solved in the medical field

Abstract

The invention relates to a vitamin E self-emulsifying ointment, which can be used for effectively enhancing the bioavailability of external vitamin E and enhancing the curative effect. According to the technical scheme of the invention, the vitamin E self-emulsifying ointment is prepared by uniformly mixing vitamin E serving as a medicament and a self-emulsifying substrate serving as a medicamentcarrier; every gram of vitamin E self-emulsifying ointment contains 20-300mg of vitamin E; the self-emulsifying substrate is prepared from 12-20 percent by weight of an oil phase, 40-60 percent by weight of an emulsifier and 20-40 percent by weight of an auxiliary emulsifying agent; the oil phase consists of refined oil, glycerin monostearate and octadecanol in the weight ratio of 8:2:1; the emulsifier consists of polysorbate 80 and RH40 in the weight ratio of 2:8, or consists of polysorbate 80 and EL in the weight ratio of 6:4; and the auxiliary emulsifying agent is glycerol. The vitamin E self-emulsifying ointment is prepared by the following steps of: putting the oil phase into a constant-temperature water bath of 80 DEG C for heating and melting; adding the emulsifier, the auxiliary emulsifying agent and the vitamin E in sequence; dissolving and stirring uniformly; standing; and cooling for curing. The vitamin E self-emulsifying ointment has a good curative effect, and is an innovation of a medicament for externally treating skin diseases.
