Novel cosmetic based on somatomedin and serine
Technical field
The invention belongs to cosmetics research and development field.Relate to a kind of novel cosmetic based on somatomedin and serine, it can promote skin regeneration and improve skin matter.
Background technology
Along with the raising day by day of people's living standard, people more and more pay attention to the personal image of oneself, and market survey finds, the women make apply some make up in to the degree of concern maximum of quality and effect.Therefore, the high-tech that development quality is good, result of use the is good product of making up are directions of cosmetic field research and development.
Along with the variation at age, the various 26S Proteasome Structure and Functions of skin are also changing.The invasion and attack of environment, particularly long-term sun exposure, more much bigger to the damage of skin more than age ageing.
Following variation appears in skin texture, physiology, the biochemical increase with the age: (1) 70 years old and comparison in 30 years old, the cell conversion ratio approximately reduces 50% in the epidermis, corium purport power fiber and collagen fiber all reduce, the reason that characteristic that the apparent pattern of the skin of aging that Here it is is thin and Clear ﹠ Transparent and corium blood vessel are easy to rupture.(2) along with the age change is big, collagen fiber and elastic fibers become connection and increase, but make the corium tropism weaker, thereby the lear energy reduction, and when skin is pinched time-out, old people's skin slowly restores to the original state.Elastic tissue degeneration causes wrinkle to be deepened.(3) melanocyte enzymatic activity attenuating (per 10 years attenuating 10-20%) causes the irregular pigmentation of skin, and hair becomes canescence.
(growth factor is to have the active cytokine of stimulating cellular growth GF) to somatomedin, and being a class, cell is grown and the polypeptides matter of manifold effects such as other cell functions by combine, regulates with special, high affine cell-membrane receptor.Be present in platelet and various adult and embryonal tissue and the most of cultured cell, the variety classes cell is had certain specificity.Generalized somatomedin has multiple, as insulin, epidermal growth factor (EGF), fibroblast growth factor (fibroblastgfowth factor, FGF), platelet source reproduction factor (platelet-derivedgrowthfactor, PDGF) and somatostatin (somatostatin=SRIH), hydrocortisone, thyroxine etc.The somatomedin of human body has multiple physiological action, can promote growth, reparation and the extra-nutrition of cell.Because when injured, disease or old and feeble former thereby sustain damage, the human growth element is that the stimulating growth factor produces, these somatomedin are promptly as fire brigade rush " fire fighting " when tissue.In numerous somatomedin, some has special effect to skin, is particularly suitable for being applied to the development of cosmetics.
Epidermal growth factor (Epidermal Growth Factor, EGF) be the intravital a kind of cytokine of forming by 53 aminoacid of machine, extensively be present in many histoorgans and the body fluid, can promote the growing multiplication of epithelial cell, fibroblast, vascular endothelial cell, physiological function is widely arranged.It is equaled to find in 1962 by U.S. scientist Stanley Cohen, and therefore wins Nobel's medical science in 1986 and encourage with the physiology.A large amount of scientific experimentss show: epidermal growth factor can promote the healing of skin trauma, has also shown wide application prospect at aspects such as treatment gastrointestinal ulceration, corneal injury, the perforation of ear drum, fracture, acute tubular damage and cancers.In addition, epidermal growth factor still is a kind of good cosmetics additive, also can be used as the interpolation composition of serum-free medium.Epidermal growth factor is former to extract from urine.Because raw material is collected difficulty, effective component content is low in the raw material, reasons such as extraction process complexity, and the extensive use of epidermal growth factor is restricted.Engineered high-tech means has been arranged, and the highly purified epidermal growth factor of mass production has become reality.Epidermal growth factor is the inherent protein of a kind of human body, plays the epidermis of repairing damage in vivo, promotes the effect of wound healing.Add epidermal growth factor in the cosmetics, can play wrinkle removing, go effect such as abnormal pigmentary deposit on the skin, increase skin elasticity, make skin smooth U.S. clean tender white.
Keratinocyte growth factor (Keratinocyte growth factor, KGF) be that known short keratinocyte (KC) is bred the strongest cytokine at present, albumen is made up of 194 aminoacid, and its gene contains three exons, two introns are a kind of mitogenic factors.KGF plays an important role in the growth of epidermis cell and renewal process, can accelerate the injury repairing and the growth of short people's corneal epithelial cell of bladder, kidney and intestinal.In addition, KGF is being put, is also being played an important role aspect the injury repairing that chemotherapy is brought.Continuous development along with keratinocyte growth factor research and application has been applied to cosmetic field, mainly acts on the horn cell of skin surface, and mucomembranous epithelial cell and fibrocyte are had certain effect.Confirmed that KGF comprises the function of the horn cell of skin: 1) promote skin keratin hyperplasia; 2) differentiation successively of promotion horn cell; 3) promoting horn cell eccrine fiber albumen such as collagen protein, 4) the shielding angle cell plastid is not subjected to the damage of extraneous factor such as ultra-vioket radiation.These effects prevent skin aging for the eubolism of skin, keep elasticity and skin smooth and fine and softly play crucial effect.
(fibroblast growth factor in early days mainly from Medulla Bovis seu Bubali and extracting solution pituitary, is the acidity or the basic fibroblast growth factor of about 150 amino acid structures FGF) to fibroblast growth factor.The nineties, use gene engineering method successfully to obtain the FGF that recombinates both at home and abroad in succession.Present known fibroblast growth factor has 23 kinds, i.e. FGF1~23.Fibroblast growth factor can be by endotheliocyte, smooth muscle cell, macrophage secretion.Its effect is to promote the migration of endotheliocyte and the propagation of smooth muscle cell, can not make the smooth muscle cell migration.Can promote neovascularization, repair the endotheliocyte of infringement.
Serine is being brought into play in the growth of fat and the metabolism of fatty acid and muscle and is being acted on, because it helps immunoglobulin and production of antibodies, the immune system of keeping health also needs serine.Serine is all being brought into play in the sheath of manufacturing processing, muscular tissue and the encirclement neurocyte of cell membrane synthetic and is being acted on.Serine can obtain from Semen sojae atricolor, brewing fermentation agent, milk product, egg, fish, lactalbumin, soybean pod, meat, nut, seafood, seed, Semen sojae atricolor, milk surum and whole wheat.Be necessary that the people knows from experience synthetic serine from glycine.Serine is the important amino acid in the nature moisturizing factor in cosmetics, and when skin cell product crack was big, moisture was just lost easily.Make the skin superficial drying coarse, even produce little microgroove, and serine can form moisture film in skin surface immediately, the barrier skin prevents water loss.Simultaneously, serine and glycine metabolite also have anti-sunlight function.
Along with the continuous development of cosmetics new raw material, new technique, new equipment, somatomedin and serine are applied in the cosmetics.But do not see that with epidermal growth factor, keratinocyte growth factor and fibroblast growth factor and serine common application in same cosmetics, collaborative playing a role improved the report and the application of skin matter better.The present invention according to certain proportioning, adopts modern crafts to make cosmetics these several active substances, and multi-efficiency promotes skin regeneration and improves skin matter.
