(3) summary of the invention
The object of the present invention is to provide a kind of very strong antioxygenic property that has, pure natural, have no side effect, be rich in the emulsifying agent for cosmetics of plurality of health care functions.
The object of the present invention is achieved like this: it comprises that percentage by weight is hydrogenated soy phosphatidyl choline 10-20 part, cholesterol 2-5 part, polyoxyethylene castor oil 1-3 part, tannic acid 2-3 part, glycerol 5-10 part, glycerol monostearate sucrose ester 1-3 part and deionized water 56-79 part.
Another object of the present invention is to provide a kind of preparation method of emulsifying agent for cosmetics: at first be that raw material is through catalytic hydrogenation with the soybean phospholipid, reaction back separating catalyst, hydrogen peroxide decolour, remove solvent, the acquisition iodine value is 20~30 hydrogenated soya phosphatide, with percentage by weight is hydrogenated soya phosphatide 10-20 part, cholesterol 2-5 part, polyoxyethylene castor oil 1-3 part, tannic acid 2-3 part, glycerol 5-10 part, glycerol monostearate sucrose ester 1-3 part and the abundant mix homogeneously of deionized water 56-79 part, makes emulsifying agent for cosmetics.
Preparation method of the present invention also has some technical characterictics like this:
1, the preparation condition of described hydrogenated soy phosphatidyl choline is with dichloromethane---alcohol mixture (V: V=3: 1) be solvent, selecting palladium catalyst, its addition for use is 5% of phospholipid consumption, at 55 ℃, Hydrogen Vapor Pressure is 0.6MPa, isothermal reaction 3h gets final product in the 1L autoclave, reaction product is after separating catalyst, hydrogen peroxide decolouring, removing solvent, can obtain iodine value is 20~30, and it is yellowish that color is, the hydrogenated soy phosphatidyl choline of no bad smell.
Soybean lecithin adopts catalytic hydrogenation method among the present invention, and the unsaturated bond fractional saturation that phospholipid is contained improves its stability and weakens or eliminate its color and abnormal smells from the patient.The present invention has adopted catalytic hydrogenation method to prepare a kind of hydrogenated soya phosphatide, for day chemical industry etc. provides a kind of novel material.
Advantage of the present invention is:
1. soybean phospholipid is through catalytic hydrogenation, and the unsaturated bond fractional saturation that phospholipid is contained improves its stability and weakens or eliminate its color and abnormal smells from the patient.
2. the present invention is body material with the hydrogenated soya phosphatide; a kind of cosmetic emulsifier that is aided with cholesterol, polyoxyethylene castor oil, tannic acid, glycerol, glycerol monostearate sucrose ester, deionized water and prepares; pure natural, have no side effect; life-time service can protect the human epidermal cell to avoid the infringement of free radical, thereby has the effect of slow down aging.
(4) specific embodiment
Below in conjunction with specific embodiment the present invention is further described:
Embodiment 1:
Present embodiment is chosen refining soybean phospholipid 200g, with dichloromethane such as 400ml---alcohol mixture (V: V=3: 1) be solvent, adding the 10g palladium catalyst, to be heated to 55 ℃, Hydrogen Vapor Pressure in the 1L autoclave be 0.6MPa, behind the isothermal reaction 3h, reaction product decolours, removes solvent through separating catalyst, hydrogen peroxide, obtaining iodine value is 20~30, and it is yellowish that color is, the hydrogenated soya phosphatide of no bad smell.
Get the hydrogenated soya phosphatide 10g of above-mentioned prepared, add cholesterol 2g, polyoxyethylene castor oil 3g, tannic acid 2g, glycerol 5g, glycerol monostearate sucrose ester 1g and deionized water 77g more respectively, above-mentioned raw materials behind high speed (5000r/m) mixing, promptly be can be applicable to various cosmetics.
Embodiment 2:
The preparation process of hydrogenated soy phosphatidyl choline is with embodiment 1 in the present embodiment, difference is to get the hydrogenated soy phosphatidyl choline 15g of above-mentioned prepared, add cholesterol 4g, polyoxyethylene castor oil 2g, tannic acid 3g, glycerol 8g, glycerol monostearate sucrose ester 2g and deionized water 66g more respectively, above-mentioned raw materials behind high speed (5000r/m) mixing, promptly be can be applicable to various cosmetics.
Embodiment 3:
The preparation process of hydrogenated soy phosphatidyl choline is with embodiment 1 in the present embodiment, difference is to get hydrogenated soy phosphatidyl choline 20g, cholesterol 5g, polyoxyethylene castor oil 3g, tannic acid 3g, glycerol 10g, glycerol monostearate sucrose ester 3g and the deionized water 56g of above-mentioned prepared, above-mentioned raw materials behind high speed (5000r/m) mixing, promptly be can be applicable to various cosmetics.
