Problems solved by technology

Because vitamin E is sensitive to oxygen and is easily oxidized, it will decompose slowly in an oxygen-containing environment, and it is also easy to decompose and lose its effect in a strong acid and alkali environment.

[0030] The preparation method of oil-in-water vitamin E emulsion of the present invention comprises the following steps:

[0031] (1) Weigh the liquid vitamin E, surfactant, solid protector and distilled water according to the weight ratio;

[0032] (2) Preparation of the water phase: add the solid protective substance molecules into distilled water and stir to dissolve or dissolve and completely wet to form an aqueous solution of the protective substance used as the external phase, and set aside;

[0033] (3) Preparation of oil phase: add surfactant to vitamin E to form oil phase used as internal phase, stir to dissolve;

[0034] (4) Put the high-speed shearing machine into the water phase and turn it on. When the speed of the shearing machine is increased to 2000-4000 rpm, slowly add the above oil phase, and after it is completely added, accelerate to 6000-13000 rpm. After 5-15 minutes, reduce the speed of the shearing machine to a complete stop, cool for 20-40 minutes, and...

Abstract

The invention relates to a vitamin E emulsifiable solution and a preparation method thereof. The vitamin oil-in-water type emulsifiable solution provided by the invention is prepared from the following components in weight ratio: 5-35% of liquid vitamin E, 10-20% of solid protector, 5-35% of surfactant and 35-79% of distilled water. According to the vitamin E emulsifiable solution and the preparation method thereof, by adopting the method of mixing the liquid vitamin E, the solid protector, the surfactant and the distilled water in a certain proportion to prepare an O / W-type vitamin E emulsifiable solution having a protection action for a vitamin E, the vitamin E emulsifiable solution can be used in a broad-spectrum (pH 2.5-14) range, and is not damaged or is less damaged so as to maintain the activity of the vitamin E emulsifiable solution, and the approaches for application are wider. Furthermore, the O / W-type vitamin E emulsifiable solution produced by the invention not only can be uniformly dispersed in water in the application, but also has a slow-release action, is extremely convenient to use, and can be widely applied to various cosmetics and other products for daily use.

Description

Technical field [0001] The present invention involves daily technology, especially a water -based oil -type vitamin E emulsion solution and its preparation method that can directly or indirectly act on cosmetics and other daily products. Background technique [0002] Vitamin E (Vitamin E) is a kind of fat -soluble vitamin, also known as nicheol acetate. It is one of the most important antioxidants. It has a lot of effects. The more common functions are listed below: [0003] Delaying aging: Vitamin E has the effect of delaying aging, mainly based on its antioxidant capacity.Vitamin E is one of the most important biological free radicals and antioxidants in the body.As a lipid -soluble vitamin, vitamin E is a broken chain anti -oxidant. The main function is to block the reaction chain of fat oxidation. It is the first line of defense of antioxidant in the body.The antioxidant effect of vitamin E is positioned as a cell membrane, which can block the formation of peroxide in the cel...
