The preparation of albumen silkworm silk and the application in cosmetics
Art
The preparation method that the present invention relates to a kind of albumen silkworm silk, and as the cosmetics additive application at cosmetic field.
Background technology
Silk peptide is the active ingredient of native fibroin hydrolyzed solution, containing 18 seed amino acids, within 10 seconds, just can permeate skin skin corium, effectively suppresses melanin to generate, controls pigment. Promote collagen protein synthesis, activating cell, improve the immunity of cell, promote the metabolism rate of skin, help to repair impaired skin histology, make low and deep tired skin add life again, thus reducing the skin of whitening, gloss in very short time. Skin is had multiple efficacies by silk peptide as can be seen here. But silk peptide does not possess the threadlike appearance of silkworm silk, add to cosmetics can not give and experience intuitively.
At present, in cosmetic field, made granule, as the additive of cosmetics, is widely used, and adds a lot of colors and effect to cosmetics, also gives the more new meaning of cosmetics. Grain products includes soluble granule and insoluble granule (frosted granule), for the profile of granule, except rule spheroidal is exactly erose. But without silkworm silk shape.
The present invention, utilizes the film property of natural macromolecular material, by orifice coagulating bath method, parcel native fibroin hydrolyzed solution (silk peptide), makes silkworm silk shape product, adds in the cosmetics of transparent system. Namely this albumen silkworm silk have effect of natural silk hydrolyzed protein, has again the outward appearance of natural silk concurrently. Not only attractive in appearance but also practical.
Silk peptide, is that silkworm fibroin matter forms water miscible peptide material through degraded. Molecular weight is typically between 500��10000, good water solubility, white powder, pH value 4.5��6.5.
Silk peptide effect one, silk peptide has natural moisture preserving, nutrition skin and promotes skin wound healing effect: often smears skin with the skin care item rich in silk peptide and can reach beauty treatment and prevent the effect of various skin disease. Clinical application proves that: wrinkled skin, dermatitis, pruritus, elimination chloasma are had good curative effect. Test result indicate that, silk peptide nonirritant, and wound healing can be accelerated. Silk peptide still prevents dust, coating, acid, alkali chemical substance to the erosion of skin and injury.
Silk peptide effect two, extremely excellent hair care function: the hair care function of silk peptide is mainly reflected in the absorbability to hair and adsorptivity, film property, damping moisture retention.Absorbability and adsorptivity: silk peptide is compared with other hydrolyzed protein (collagen protein, osseocolla albumen, glutin etc.), and maximum feature is exactly nutritious easily absorbed by hair. Silk peptide relies primarily on osmosis for the absorption of skin and hair, has substantivity. Silk peptide concentration improves, then the absorbtivity of silk peptide is also increased by hair accordingly. If the hair of damaged, absorption and adsorbance to low-molecular-weight silk peptide are bigger, and correspondingly silk peptide is more obvious to reparation and the protective effect of hair. Molecular weight is at the silk peptide of 500-2000, and its film property on hair is fabulous, and the film distinctive gloss of tool, and hair good hand touch is flexible. X-ray diffraction method shows: the film that silk peptide is formed is �� type crystallization, the film that silk peptide is formed on hair, can increase hair elasticity and gloss. It also is used as hairspray simultaneously, PVP, collagen peptide, starch based aqueous solution and silk peptide is compared, under the wet condition of 80% relative humidity, makes setting agent with silk peptide, hair can be made to keep good hair style for a long time.
Silk peptide effect three, damping moisture retention: hair loses certain moisture and will dry, jag, easily snap off, come off. Silk peptide can prevent moisture content from too much evaporating at the film that hair surface is formed, as natural moisturizing factor, moreover it is possible to regulates the wettability in the little space of hair surface, makes hair soft, smooth.
Natural macromolecular material has and a variety of has gelation and film property, it is possible to for carrier and the filmogen of silk peptide, for instance: sodium alginate, gellan gum, carrageenan, locust bean gum.
Sodium alginate is a kind of natural polymer forming agent, Sargassum (Thallus Laminariae (Thallus Eckloniae), Brown algae, the edible marine algae plant such as Alga Sgrgassi Enerves Macrocystis pyrifera (L.) Ag.) extract the by-product of processing. Sodium alginate can make various gel, and keeps good colloid form, and sepage or contraction, satisfactory mechanical property do not occur, and is the fabulous novel carriers of a kind of stability and forming agent. Spherical additive (roe elite granule, the Jojoba granule) majority of present cosmetic field produces with sodium alginate for carrier and forming agent.
Gellan gum also known as triumphant can glue, be a kind of microorganism edible glue of exploitation Kelco company of U.S. eighties in 20th century. It is a kind of Linear Polymer polysaccharide, can form the gel of all-transparent, and its gelling performance is more more superior than xanthan gum. The solidification temperature of gellan gum gel is within the scope of 30-45 DEG C, and the fusion temperature of gel both can lower than being higher than 100 DEG C, and this depends on the condition such as cation type and concentration. Cationic existence simultaneously, can generate hard brittle gel, and its hardness is directly proportional to gellan gum concentration, and produces maximum gel hardness when relatively low divalent cation concentration. Add xanthan gum, locust bean gum in gellan gum, its gel hardness can be made to reduce and elastic enhancing, thus obtaining a kind of desirably filmogen and carrier.
Carrageenan is also known as carrageenin, Ireland extractum and antler glue, this is by D-galactopyranose and 3, the calcium of high molecular weight polysaccharide class sulfuric ester of 6-Anhydrogalactose. composition, magnesium, potassium, sodium, ammonium salt, according to sulfuric ester in molecule in conjunction with kenel, carrageenan is divided into 3 kinds of types: k-type, ��-type, L-type etc. Kappa-Carraginan is referred to as the quick carrageenan of potassium; L-carrageenan is then referred to as calciphylaxis carrageenan, L-carrageenan and calcium ion can be formed completely not syneresis, gel that is whippy and that glue very much, it is unique freeze thaw stable type carrageenan.When K-carrageenan is mixed with L-carrageenan, the elasticity that can improve gel can prevent again syneresis. Locust bean gum is mixed with carrageenan makes gel become more high resilience and not crisp, and the cooperative effect let us of both glue obtains again a kind of extraordinary silk peptide forming agent and carrier.
Locust bean gum, a kind of white to yellow powder, granule or flat sheet, odorless or be with micro-smelly, colourless, mainly contain mannose and gala warded off, molecular weight is approximately 300,000 dalton, is extremely good thickening stabilizing agent. Its most important feature is it and the hydrophilic colloid such as agar, carrageenan and xanthan gum has good gel cooperative effect, the consumption level after compound can be made very low and improve gel tissue's structure.
So far, make thread products application with natural macromolecular material have not been reported for carrier and film former parcel silk peptide at cosmetic field.
