Summary of the invention
The present invention will solve the problem of obtaining and provide a kind of permeation-promoting combination for cosmetic, and this permeation-promoting combination for cosmetic uses safety, mechanism is obvious, compatibility is good.
Using for reference the medical domain achievement in research can find, the infiltration conduction of functional mass on skin undertaken by following approach:
1, medicine is transported and is absorbed by the dermal papilla layer, thereby enter when injected organism tissue by skin arterial channel, horny layer transhipment (comprising cell internal diffusion, intercellular substance diffusion) and epidermis deep layer, corium.
2, the material absorbing at skin point place.Compare with other places skin, the Skin at Acupoints impedance is low, electric capacity is large, current potential is high, is conducive to the Transdermal absorption of material.
3, the absorption of mucosa place material.Be the common medicine position of medicine external evenly such as the hypoglossis mucous membrane in oral cavity, nasal mucosa, mucous membrane of rectum etc., mucosa does not have horny layer, and that medicine penetrates is comparatively easy, speed is fast.
4, hydration.Cuticular water content is the function of envionmental humidity.Horny layer is expandable into porous state behind hydration, be easy to material and penetrate.Facts have proved that the percutaneous rate of functional mass can increase by 4 to 5 times, the colleague can also make Pi Wen increase to 37 ℃, the acceleration blood circulation from 32 ℃.
5, the effect of surfactant or transdermal enhancer.Such as laurocapram, dimethyl sulfoxide etc.
6, the facilitation of aromatic herbs.
Technical scheme provided by the invention is: permeation-promoting combination for cosmetic, main component are amino acid humectant (5%-15% weight), hyaluronate sodium (1%-3% weight), nicotiamide (5%-15% weight), allantoin (0.1%-0.5% weight), deionized water (75%-77% weight).
The present composition is the function of envionmental humidity according to cuticular water content mainly, and horny layer is expandable into porous state behind hydration, is easy to the principle that material penetrates and finishes.
1, short principle for a change skin chromaticness layer lipid and the protein structure of oozing of azone, it is mobile to increase cutin, makes cuticular lipoids produce irregular alignment.
2, present composition ingredient is proven as safety, and penetration mechanism is also different from azone, therefore can not cause potential hazard to skin
3, the alkane compound compatibilities such as composition and vaseline are good in the present composition,
4, the short effect of oozing of the present composition is better than azone.

Get 100 ml beakers, add 76.9 gram deionizations, add hyaluronate sodium 3 grams, and use heating by electric cooker, be stirred to hyaluronate sodium with electric blender simultaneously and dissolve fully, be heated to 80 ℃ and add allantoin 0.1 gram, amino acid humectant 15 grams, after naturally being cooled to room temperature, add nicotiamide 5 grams, and supply volatilization water to 100 gram and namely finish.
Embodiment 3: amino acid humectant 11.7%, hyaluronate sodium 1%, nicotiamide 12%, allantoin 0.3%, deionized water 75%, described percentage ratio are weight ratio.
Get 100 ml beakers, add 75 gram deionizations, add hyaluronate sodium 1 gram, and use heating by electric cooker, be stirred to hyaluronate sodium with electric blender simultaneously and dissolve fully, be heated to 80 ℃ and add allantoin 0.3 gram, amino acid humectant 11.7 grams, after naturally being cooled to room temperature, add nicotiamide 12 grams, and supply volatilization water to 100 gram and namely finish.
The used amino acid humectant of the application is the commercially available prod, main component: natural trimethyl glycine, adopt color analyse isolation technics from the molasses of beet root, extracts make natural product, outward appearance: white crystalline powder content 〉=99% moisture :≤1.0% 5% aqueous solution pH:5.0-7.0.
The short effect of oozing of the present composition can be verified by cinnamic acid percutaneous (Corium Mus) permeability test, makes 5 samples before the experiment, distinguishes with A, B, C, D, E, and the concrete composition of each sample is as follows:
Sample A:99% deionized water, 0.1% cinnamic acid
