Embodiment 1

[0014] In this example, 200 g of refined soybean lecithin was selected, and 400 ml of dichloromethane-ethanol mixture (V: V=3: 1) was used as a solvent, and 10 g of palladium catalyst was added and heated to 55 ° C in a 1 L autoclave under a hydrogen pressure of 0.6 MPa. , After constant temperature reaction for 3 hours, the reaction product is decolorized by separation catalyst, hydrogen peroxide, and solvent removed to obtain hydrogenated soybean lecithin with an iodine value of 20-30, a light yellow color, and no unpleasant smell.

[0015] Get 10g of hydrogenated soybean lecithin prepared by the above-mentioned process, then add 2g of cholesterol, 3g of polyoxyethylene castor oil, 2g of tannic acid, 5g of glycerin, 1g of sucrose monostearate and 77g of deionized water respectively, and the above-mentioned raw materials are processed by high-speed (5000r / m) After mixing, it can be applied to various cosmetics.

Embodiment 2

[0017] The preparation process of hydrogenated soybean lecithin in this example is the same as in Example 1, the difference is that 15g of hydrogenated soybean lecithin prepared by the above process is taken, and then 4g of cholesterol, 2g of polyoxyethylene castor oil, 3g of tannic acid, 8g of glycerin, Glycerol sucrose monostearate 2g and deionized water 66g, after mixing the above raw materials at high speed (5000r / m), they can be applied to various cosmetics.

Embodiment 3

[0019] The preparation process of hydrogenated soybean lecithin in this example is the same as in Example 1, except that 20 g of hydrogenated soybean lecithin, 5 g of cholesterol, 3 g of polyoxyethylene castor oil, 3 g of tannic acid, 10 g of glycerin, and glycerin monohard prepared by the above process are used. Sucrose fatty acid ester 3g and deionized water 56g, after mixing the above raw materials at high speed (5000r / m), they can be applied to various cosmetics.

Abstract

The invention provides an emulsifier for cosmetics and a preparation method thereof. The emulsifier comprises the following compositions in weight percent: 10 to 20 portions of hydrogenated soybean phosphatidylcholine, 2 to 5 portions of ornitrol, 1 to 3 portions of polyoxyethylene castor oil, 2 to 3 portions of tannic acid, 5 to 10 portions of glycerol, 1 to 3 portions of glycerol monostearate sucrose esters and 56 to 79 portions of de-ionized water. The emulsifier has strong antioxygenic property, is fully natural without side effects, and has various health care functions. The emulsifier for the cosmetics is prepared by taking the hydrogenated soybean phosphatidylcholine as main raw material, along with the ornitrol, the polyoxyethylene castor oil, the tannic acid, the glycerol, the glycerol monostearate sucrose esters and the de-ionized water, is fully natural without side effects, and can protect epidermal cells of human body from being invaded by freeradicals after long-term use, thereby having the efficacy of delaying senescence.

Description

(1) Technical field [0001] The invention relates to an emulsifier for cosmetics, in particular to a cosmetic emulsifier mainly composed of active hydrogenated soybean lecithin and a preparation method thereof. (2) Technical background [0002] Most of the emulsifiers used in cosmetics are chemical synthetic substances, and long-term consumption has certain toxic effects on the skin. Hydrogenated soybean lecithin, due to the use of catalytic and hydrogenation processes, makes the unsaturated chains of unsaturated fatty acids in the molecular structure of soybean lecithin disappear, thereby greatly improving the chemical stability, dispersibility, and emulsification of lecithin. It is an excellent natural Emulsifier has a protective effect on human skin, so it can be widely used in various cosmetics. (3) Contents of the invention [0003] The object of the present invention is to provide a kind of emulsifier for cosmetics which has strong anti-oxidation performance, is pure...
