Abstract

The invention discloses a preparation method of a cosmetic bamboo leaf composition. The preparation method comprises the following steps: taking 10 parts of bamboo leaves dried and crushed into 50 meshes, soaking the bamboo leaves in 20-40 parts of an ethanol solution of 70% for 30 minutes, then filtering to obtain a solid ingredient, adding 50-100 parts of a salt solution containing 1%-2% of salt, soaking for 1-3 hours at the temperature of 30-50 DEG C, filtering to obtain a liquid ingredient, filtering through a ceramic membrane, concentrating to obtain a bamboo leaf extracting solution with Brix up to 20%, taking 1-3 parts of an emulgator, heating and dissolving in 60-80 parts of glycerine, then adding 10-30 parts of the bamboo leaf extracting solution, continuing to stir and dissolve evenly to obtain an aqueous phase, shearing the aqueous phase at the revolving speed of 5,000-10,000 rpm, weighing 7-9 parts of natural vitamin E, slowly adding the natural vitamin E into the aqueous phase, and shearing for 15-20 minutes till the average grain diameter of an emulsion is 0.2 [mu]m-0.6 [mu]m, so as to obtain the bamboo leaf composition. A prepared antioxidant has a strong antioxidant ability, is water-soluble, is convenient to use, and is applied to various cosmetics.

Description

A kind of preparation method of Folium Bambusae compositions used for cosmetic

Technical field

The present invention relates to the preparation method of a kind of cosmetics additive, particularly to the preparation side of a kind of Folium Bambusae compositions Method.

Background technology

Herba Lophatheri is traditional heat and toxic materials clearing away medicine, is the natural plants of medicine-food two-purpose.Containing flavone glycoside and perfume (or spice) in Folium Bambusae The compositions such as legumin lactone, are a kind of natural antioxidants.Natural Vitamin E (VE) is a kind of natural antioxidant, has Certain oxidation resistance, VE is fat-soluble product, water insoluble, is usually used in oils and fats preventing Oxidation of Fat and Oils.VE and traditional Folium Bambosae extract cost is slightly higher, and antioxidant effect is unstable, has certain restriction in application.

Summary of the invention

For overcoming the deficiencies in the prior art, it is an object of the invention to provide the preparation method of a kind of Folium Bambusae compositions, system The standby antioxidant product obtained is stable, and oxidation resistance is strong.

For achieving the above object, the preparation method of Folium Bambusae compositions involved in the present invention includes following preparation process:

(1) Folium Bambusae extracts: in mass, takes drying and crushing to 10 parts of the Folium Bambusae of 50 mesh, is placed in 20-40 part 70% ethanol solution Soak 30min, then cross leaching solid constituent, add the 50-100 part saline solution containing 1%-2% Sal, soak 1-in 30-50 DEG C 3h, cross leaching liquid component, be concentrated into after ceramic membrane filter Brix reach 20% extract solution of bamboo leaves；

(2) preparing Folium Bambusae compositions: take emulsifying agent 1-3 part, heating for dissolving, in 60-80 part glycerol, is subsequently adding 10-30 part bamboo Leaf extract, continuation stirring and dissolving is uniform obtains aqueous phase；5000-10000rpm rotating speed down cut aqueous phase, and weigh natural Vitamin E 7-9 part, is slowly added in aqueous phase, and 15-20min is to emulsion mean diameter 0.2 μm-0.6 μm in shearing, obtains Folium Bambusae compositions.

Wherein, described emulsifying agent is ten polyglycerol monooleate, ten Plurol Oleique CC497s, ten polyglycereol mono laurates Ester or ten polyglycereol dilaurates.

The preparation method of the Folium Bambusae compositions used for cosmetic of the present invention has the advantage that

(1) the Folium Bambusae compositions that the present invention prepares has the strongest oxidation resistance, and application experiment shows, its antioxidation energy Power is suitable with the effect of equal quality VE, and in Folium Bambusae compositions, the addition of VE is less than 10%, is equal quality Folium Bambosae extract 3 times, not only do not have, because emulsifying and embedding have impact on the antioxidant effect of VE and Folium Bambosae extract, to serve on the contrary significantly Collaborative reinforced effects.High anti-oxidation activity can reduce consumption, reduces the production cost of client；

(2) antioxidant that the present invention prepares is water solublity, and easy to use, application is wide；

(3) preparation method of the Folium Bambusae compositions that the present invention provides, technique is simple, it is not necessary to the complicated technologies such as homogenizing, equipment investment Significantly reduce with energy consumption.It addition, the present invention is in Folium Bambusae extraction step, carries out extraction with the saline solution containing 1-2% Sal and prepare Extract solution of bamboo leaves, obtains extract solution of bamboo leaves and has promotion emulsification function, reduces the addition of emulsifying agent in finished product, only accounts for whole The 1-3% of product, and tradition needs emulsifying agent addition about about 5% in the emulsion that homogenizing could be stable.
