Abstract
The invention discloses an intelligent ultraviolet-proof additive used for cosmetics. The intelligent ultraviolet-proof additive comprises two parts, wherein one part is a physical factor with an ultraviolet-proof function, and the other part is a chemical factor with an ultraviolet-proof function. The intelligent ultraviolet-proof additive is characterized in that through a hydrophilic/dewatering mechanism, the chemical factor is embedded by the physical factor. The intelligent ultraviolet-proof additive has the advantages that through adjusting the types and the embedding quantity of the chemical factor, a certain amount of chemical factors can be intelligently released under the ultraviolet irradiation so as to achieve the wide waveband and long-time ultraviolet protection; and a certain amount of chemical factors can be recovered when no ultraviolet irradiates, so that damages to the skin are reduced.
Description
Technical field
The present invention relates to a kind of intelligent anti-ultraviolet additive, especially relate to a kind of used for cosmetic intelligence anti-ultraviolet additive.
Background technology
Ultraviolet is the general name of electromagnetic spectrum medium wavelength from 10nm to the 400nm radiation, and the ultraviolet that the occurring in nature sun can be radiated the earth is mainly the ultraviolet B radiation (UVB) of wavelength 290nm ~ 320nm and the long wave ultraviolet (UVA) that wavelength is 320nm ~ 400nm.UVB can produce strong light to skin and burn, and makes corium vasodilation, and the symptoms such as redness, blister can appear in skin.Erythema, inflammation, skin aging can appear in permanent irradiation skin, and severe patient can cause skin carcinoma.UVA can make skin tanning, and long-term irradiation can make skin aging and damage.
At present, the anti-ultraviolet factor in the sunscreen cream mainly is divided into physical agent and chemokines.Physical agent mainly is the inorganic oxides such as titanium dioxide, zinc oxide, Tungstic anhydride., and they spread out at skin, sunlight is formed reflection, to reach the purpose of anti-ultraviolet.Chemokines mainly is the Organic substances such as para-amino benzoic acid and derivant thereof, anthranilic acid, cinnamic acid, benzophenone class, group-substituted acrylonitrile, but their absorbing ultraviolets make it be converted into molecular vibrational energy or heat energy reaches sun-proof effect.
But the anti-ultraviolet factor of adding in the sunscreen cream at present is all more single, causes ultraviolet guard band is limited in scope; Or simple physical mixed, addition is also relatively fixing, can not realize long anti-ultraviolet function; The more important thing is that present sunscreen cream can not pass through extraneous ultraviolet irradiation, intelligence is regulated the release of anti-ultraviolet chemokines, more do not have the recovery effect to these factors, the consequence that under ultraviolet irradiation, causes thus the quantity not sufficient of the anti-ultraviolet factor to penetrate with shielding of ultraviolet, thus cause losing preventing ultraviolet effect at the timely long time of different ultraviolet radiation intensities; The more important thing is that most of chemical anti-ultraviolet factor pair skin has injury to a certain degree, be attached to for a long time skin surface and in time cleaning meeting to the skin injury.
Summary of the invention
Technical problem to be solved by this invention be a kind of ultraviolet protection wave-length coverage of preparation wide, have long time, long-acting dual preventing ultraviolet effect, can reduce the anti-ultraviolet additive of anti-ultraviolet factor pair skin injury simultaneously.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of used for cosmetic intelligence anti-ultraviolet adds agent and comprises that two parts form, a part is the physical agent with anti-ultraviolet function, a part is the chemokines with anti-ultraviolet function, by parent/hydrophobic mechanism, physical agent embedding chemokines, intelligence discharges a certain amount of chemokines under ultraviolet radiation, can reclaim a certain amount of chemokines during without ultraviolet radiation.
The above-mentioned physical agent with anti-ultraviolet function can be the nano zine oxide, titanium dioxide, tin ash, Tungstic anhydride. of porous etc., and metal-oxide microsphere that parent/hydrophobicity changes and at least a or several mixture in the doped derivatives thereof can occur under ultraviolet irradiation.The size of microsphere is in 10nm ~ 800nm scope.
But the above-mentioned chemokines with anti-ultraviolet function is aminobenzoic acids, cinnamic acid, benzophenone class, group-substituted acrylonitrile, dibenzoyl methane class, triazines and hindered amines etc. has at least a or several mixture in hydrophobic performance and the absorbing ultraviolet Organic substance.
Above-mentioned anti-ultraviolet physical agent mixes molal weight than being 1:0.005 ~ 500 with the anti-ultraviolet chemokines.
Above-mentioned parent/hydrophobic mechanism refers to the affinity of water and dredges scolding property.In water isopolarity solution, hydroaropic substance can see through hydrogen bond and water forms of short duration bond, and lyophobic dust can be mutually exclusive with water, gets together.
Above-mentioned physical agent is to the embedding of chemokines, is utilize that physical agent has enough large nanometer level microporous, adopts certain method, chemokines entered have in the micropore inner chamber of physical agent of a constant volume, and is not dissolved.Micropore size is in 0.1nm ~ 100nm scope, and the micropore cavity volume is at 50nm
3~ 5 * 10
8Nm
3In the scope.
The embedding method that above-mentioned physical agent carries out chemokines comprises at least a or several mixing application in the sedimentation method and coprecipitation, polishing, freeze-drying, spray drying method, solid-liquid method or the inclusion methods such as gas-solid method and solid phase method.
The above-mentioned mechanism that discharges chemokines under ultraviolet radiation is, physical agent can occur from hydrophobicity to hydrophilic transformation under ultraviolet irradiation, because the variation of parent/hydrophobicity effect, so that the hydrophobicity chemokines that embedding is advanced in the micropore can be ostracised out.Do not having under the condition of ultra-vioket radiation, physical agent can be returned to hydrophobicity from hydrophilic again, can reclaim a certain amount of chemokines.
Above-mentioned release scope a certain amount of and a certain amount of chemokines of recovery is 0 ~ 100% of chemokines addition.
Compared with prior art, the invention has the advantages that: 1) adopt physical agent embedding chemokines, be not simple physical mixed, thereby increased the addition of the anti-ultraviolet factor, may reach long preventing ultraviolet effect; 2) by regulating kind and the embedding amount of chemokines, realize ultraviolet protection broadband, the long time effect; 3) realized the intelligent control of anti-ultraviolet.Because ultraviolet irradiation intensity and duration can be controlled the parent/hydrophobicity of physical agent, and then the burst size of regulation and control chemokines, so that the anti-ultraviolet additive can be realized the release of controlled chemokines according to the ultraviolet variation of occurring in nature, reach intelligent anti-ultraviolet purpose.Be hydrophobicity and can reply without anti-ultraviolet physical agent under the ultraviolet irradiation, can realize the partially recycled of chemokines, reduce the damage to skin.
