Description

A kind of active collagen-beta-schardinger dextrin-facial film and preparation method thereof
Technical field
The present invention relates to daily cosmetics field.In particular to a kind of active collagen-beta-schardinger dextrin-facial film and preparation method thereof.
Background technology
U.S. is the topic that women is eternal.Along with era development, the life of people is become better and better, and increasing people starts to focus on the quality of life, especially women.So the application of cosmetics is more and more extensive, thus has driven the development of cosmetic science technology.Facial film is the one in daily cosmetics, by it to the of short duration laminating action by contact of face, and the air that temporarily isolation is extraneous and pollution.Isolation of short duration like this can improve skin temperature, and the pore of skin is expanded, and then promotes secretion and the metabolism of sweat gland, is conducive to the oil substances that skin gets rid of the metabolic noxious products of epidermis cell and accumulation.Simultaneously the oxygen content of skin can also be made to increase, the moisture in facial film infiltrates the horny layer of epidermis, makes skin become soft and naturally bright and high resilience.
In order to make facial film have more function, facial film of today mostly also containing various natural active matter to make facial film reach clean, convergence, whitening, moisturizing, the effect such as crease-resistant.But natural active matter is directly added in facial film mainly with blended form greatly by the facial film that the major part of selling on the market contains natural active matter, this can not make natural active matter play its due effect.Reason has two aspects: one, and a lot of natural active matter is as also unstable in tea polyphenols, beta-carotene etc., and its structure very easily changes under the impact of heat, air, light or chemical environment, thus loses its original function; Its two, some natural active matter causes the content of effective ingredient in facial film to be restricted as arbutin, vitamin E etc. because of its poorly water-soluble, does not thus also reach due effect.Therefore, improving the stability of natural active matter and dissolubility, to make it play its due effect be that we must not irrespective problem.
Beta-schardinger dextrin-is the cyclic oligosaccharide be formed by connecting with α-Isosorbide-5-Nitrae-glucoside bond by seven D type Glucopyranose .s.Because the glycosidic bond connecting glucose unit can not rotate freely, therefore beta-schardinger dextrin-molecule has slightly conically hollow cylinder three-dimensional ring structure.In the structure, in cavity because the shielding action being subject to c h bond defines hydrophobic region.Comparatively big uncork end (upper end) is by C 2and C 3secondary hydroxyl form, smaller opening end (lower end) is by C 6primary hydroxyl form, there is hydrophilic.Due to hydrophobic in beta-schardinger dextrin-, outer hydrophilic and cavity size this characteristic moderate, can be combined with many kinds of substance and form Host-guest inclusion complex.After beta-schardinger dextrin-and material form clathrate, guest molecule can be made from the impact such as light, oxygen in external environment, therefore can improve its stability.And, by beta-schardinger dextrin-, the hydrophobic part of material is wrapped up, improved the dissolubility of guest molecule by the hydrophilic of beta-schardinger dextrin-outside.Therefore beta-schardinger dextrin-can play the effects such as good protection, stable and solubilising to guest molecule.Beta-schardinger dextrin-is applied to cosmetic field embedding natural active matter, natural active matter just can be made from the impact such as light, oxygen in external environment, increase its stability, make it still can keep natural activity before use.In addition, the dissolubility of natural active matter can also be improved, make its content be enough to reach required concentration, play good effect.Therefore, the use of beta-schardinger dextrin-provides a good approach for natural active matter plays its due effect.
Collagen protein is the helical fiber albumen be made up of three peptide chains, comparatively horn of plenty of originating.According to the document delivered both at home and abroad and patent display, collagen protein is very conservative in evolution, and difference in genera is less, thus has fabulous adsorptivity and the compatibility to skin, also has good biodegradability and low antigenicity in addition.Find after deliberation, collagen protein has certain repair to ultraviolet injury, and in cosmetic formulations, has good compatibility, stability, antibiotic property and can block brown pigment generation.Meanwhile, collagen protein contains the hydrophilic groups such as a large amount of amino, hydroxyl, has good moisture-keeping function.In addition, collagen protein has skin-active reparation and moisturizing lock water in conjunction with white class use, increase substantially cuticular accretion rate, accelerates cell proliferation, repairs damaged cell, reduces the effect such as wrinkle and increase elasticity of skin, therefore, collagen protein has extremely important status at cosmetic field.
This method utilizes beta-schardinger dextrin-and natural active matter to form Host-guest inclusion complex, first makes the embedding type beta-schardinger dextrin-solution comprising natural active matter; Again by embedding type beta-schardinger dextrin-solution and collagen solution blended, make the mixed solution of embedding type beta-schardinger dextrin-and collagen protein; Finally above-mentioned blend solution deaeration is injected mould freezing 1 ~ 7 day, lyophilization makes the collagen protein-beta-schardinger dextrin-facial film comprising natural active matter.Active collagen prepared by the present invention-beta-schardinger dextrin-facial film is effectively easy to use, safe; And the natural active matter of multiple different efficacies can be embedded according to actual needs, reach whitening, speckle dispelling, crease-resistant, repair the multiple efficacies such as skin; Facial film degradable, can not cause environmental pollution, has good market application foreground.Up to the present, pertinent literature or invention is not yet had to carry out report to this research.
Summary of the invention
In order to make natural active matter in facial film play its due effect, the present invention adopts beta-schardinger dextrin-can improve guest molecule stability and this feature of dissolubility, makes active collagen-beta-schardinger dextrin-facial film with collagen protein by a series of process.
