Abstract
The invention discloses a kind of preparation method of pearl whitening additive used for cosmetic, it is related to beauty makeups technical field.The present invention uses nanometer pulverization technology by pearl powder size controlling below 100 nanometers first, aids in eutectic reagent abstraction technique and aqueous two-phase extraction to close CO with microwave ultrasonic wave2Counter-current extraction techniques are extracted and purified to obtain to granatum is rich in polyphenol extract, and finally using emulsification hybrid technology, pearl powder and glycerine and polyphenol extract are uniformly mixed to get into pearl whitening additive.Pearl powder particle diameter is small in the pearl whitening additive obtained through the present invention, is advantageous to absorption of the skin to active ingredient, and cosmetics feel silk is slided, while effectively strengthens the antioxidation of cosmetics.In addition, pearl whitening additive is not only non-stimulated, skin compatibility is good and can be widely applied in the cosmetics such as foundation emulsion, creams, suncream, elite breast.
Description
Technical field
The present invention relates to beauty makeups technical field, specially a kind of preparation side of pearl whitening additive used for cosmetic
Method.
Background technology
In recent years, as people live, the aggravation of the quickening of work rhythm and environmental pollution, the skin that people face
Problem is more and more, and especially obscure, pigmentation of the colour of skin etc. turns into common problem, and skin-lightening cosmetic is also therefore as shield
One focus of skin product development field.With increasingly mature, concern of the consumer to skin-lightening cosmetic of people's consumption idea
Emphasis is not only only that its is both effectiveness, while also more focuses on its security.
Most of whitening product in the market is all to be modified by adding titanium dioxide with reaching to brighten with beauty
Purpose, thin film is formed on skin using titanium dioxide, improves the colour of skin, but skin whitening is instant whitening, it is impossible to reach
To the purpose of real skin whitening, and if it is long-term use of, easily cause clogging of pores.Pearl powder is applied to rise in cosmetics
Whitening function, but be that the larger pearl powder of particle diameter is added in cosmetics mostly, active ingredient preferably can not be inhaled by skin
Receive, influence cosmetic result.Therefore a non-stimulated natural whiting skin care item are developed to have great importance.
The content of the invention
The present invention solves the problems, such as to there is provided a kind of preparation method of pearl whitening additive used for cosmetic, of the invention
The pearl whitening additive pearl powder particle diameter of preparation is small, skin good absorbing, can remove skin freedom containing pomegranate peel polyphenol simultaneously
Base, prevent skin senescence.
To solve the above problems, the present invention provides following technical scheme：A kind of pearl whitening additive used for cosmetic
Preparation method, it is characterised in that comprise the following steps：

Enter vortex centrifugal after salting liquid and formed after aqueous two-phase to take phase to add ethanol precipitation eutectic reagent in upper phase and by eutectic
Reagent is reclaimed, and ethanol is obtained extracting medicinal extract after being mutually evaporated under reduced pressure, and medicinal extract is transferred into supercritical CO2In counterflow extraction device,
15-20 MPa extracting pressures, medicinal extract is purified under the conditions of 3-6 MPa separating pressures, obtain the granatum rich in polyphenol and carry
Take thing；
（3）4kg nano-glass pearl powders are taken to add pomegranate rind extract after being mixed with glycerine, setting high-speed emulsification pretreatment machine is cut
After cutting speed degree is 14000-16000rpm, emulsification is carried out with glycerine to pearl powder and mixed, the pearl used for cosmetic stablized
Whitening additive.
Further, step（1）Described in the particle diameter of zirconia ball be 1-2mm；The tributyl phosphate addition is
0.5-2%。
Further, step（1）Described in oven drying temperature be 500-600 DEG C；Described drying time is 10-
14h；The average grain of the Nano grade pearl powder is not more than 100nm.
Further, step（2）Described in eutectic reagent for Choline Chloride-urea, Choline Chloride-glycerine, chlorination
A kind of transparent solution of stable uniform that in choline ethylene glycol is formed in 80 DEG C of water-baths；Described eutectic reagent-water mixes
Bonding solvent is that eutectic reagent presses 8 with water：The homogeneous mixed solution formed after 2 volume ratio mixing；Described granatum is thin
The liquid-solid ratio of born of the same parents' level micro mist and eutectic reagent-aqueous solvent is 1：5-10.
Further, step（2）Described in salting liquid be ammonium sulfate, sodium sulphate, sodium citrate and dipotassium hydrogen phosphate
In one kind；The concentration of the salting liquid is 0.25-0.5g/mL.
Further, step（2）Described in supercritical CO2The flow velocity of counter-current extraction is 14-18L/h；The granatum
The content of polyphenol is 60-80% in extract.
Further, step（3）Described in pearl powder and glycerine mass volume ratio be 1：3-5；The granatum carries
It is 5-10% to take thing addition；The high speed shearing emulsification time is 8-10min.
Further, step（3）Described in pearl whitening additive used for cosmetic can be used for foundation emulsion, creams, anti-
Shine in the cosmetics such as frost, elite breast.
As a result of above-mentioned preparation method, the present invention has the advantages that compared with prior art：
The present invention uses nanometer pulverization technology that below 100 nanometers, pearl powder size controlling is advantageous into skin to active ingredient
Absorption, and cause cosmetics feel silk slide；Eutectic reagent technique and aqueous two-phase extraction is aided in close using microwave-ultrasonic
CO2Counter-current extraction techniques carry out abstraction purification to granatum and obtain being rich in polyphenol extract, effectively strengthen the antioxygen of cosmetics
Change acts on；Using emulsification hybrid technology, pearl powder is mixed with glycerine and polyphenol extract uniformly mixes, ensure that additive
Stability.In addition, pearl whitening additive, no skin irritatin, makes up available for foundation emulsion, creams, suncream, elite breast etc.
In product.
