Hyaluronic酸（hyaluronic酸)

Hyaluronic acid (hyaluronic acid) Product Name: Hyaluronic acid English name: Hyaluronic acid; HA Alias Products: Hyaluronic acid sodium Properties: white amorphous solid, odorless and tasteless, there are hygroscopic, soluble in water, insoluble in organic solvents. Effect: Hyaluronic acid is a glucuronic acid and N-acetyl-glucosamine disaccharide repeating unit composed of connected straight-chain polymer mucopolysaccharide, widely found in interstitial cells of humans and animals, eye vitreous, umbilical cord, skin, joint synovial fluid, and male comb, and many other soft connective tissue. Commodities in general for its hyaluronic acid sodium salt, ie sodium hyaluronate (Sodium Hyaluronate), habit is still referred to as hyaluronic acid. Hyaluronic acid is a new and advanced biological products at home and abroad, the molecular weight of tens of thousands to several million of its aqueous solution with a high moisture retention, visco-elasticity and lubrication, can be widely used in cosmetics, medicine, beauty and health food industry. 1, Cosmetic Grade Hyaluronic acid: Hyaluronic acid is a wide range of skin and other tissues in the presence of natural biological molecules, has an excellent moisturizing effect, the internationally known as an ideal natural moisturizing factor (Natural MolsturlZlng Factor, NMF). It is found in nature, the best performance of the cosmetics moisturizing substances. Hyaluronic acid acts on the skin surface of the skin, macromolecular HA can be formed on the surface layer of breathable film, make the skin smooth and moist, and can be separated from bacteria, dust, UV intrusion, protect the skin from abuse; small molecule and transparent quality acid can penetrate leather, with a slight expansion of capillaries, increase blood circulation, improve intermediary metabolism, promoting the role of skin nutrient absorption, with a strong eliminating wrinkles, increase skin elasticity, slow down skin aging. Hyaluronic acid can also promote the proliferation and differentiation of epidermal cells to remove oxygen free radicals, can prevent and repair skin damage. Hyaluronic acid aqueous solution with high viscosity, allows water phase thickening; with the emulsified oil phase of the paste uniformly fine, with a stable emulsification. Hyaluronic acid is a high-end cosmetics, the best natural moisturizing ingredients, it is compatible with good, almost can be added to any beauty cosmetics, widely used in cream, lotion, cosmetic water, essence, facial cleanser, shower gel, shampoo hair extension agent, mousse, lipstick and other cosmetics, in general, adding amount of 0.05-0.5%. Second, pharmaceutical grade Hyaluronic acid: Hyaluronic acid is the composition of human mesenchymal cells, eye vitreous, synovial fluid and other major components of connective tissue, water retention in the body to play to maintain the extracellular space, adjusting osmotic pressure, lubrication, promote cell repair an important physiological functions. Hyaluronic acid molecule contains a large number of carboxyl and hydroxyl, in the water; allow fluid to form intramolecular and intermolecular hydrogen bonds, which makes them a powerful role in water retention can be combined with more than 400 times its own water; at a higher concentration of When, because of its role in the formation of intermolecular complex three-tier network structure, its aqueous solution but also has significant visco-elastic. Hyaluronic acid as a main component of intercellular matrix, directly involved in the regulation of cell communication within and outside the electrolyte to play physical and molecular information on the role of the filter. Macromolecules of hyaluronic acid on cell movement, proliferation, differentiation and inhibition of phagocytic function, small molecules, there to promote the role of hyaluronic acid. 3, hyaluronic acid has a unique physical and chemical properties and physiological functions in medicine has been widely used. Hyaluronic acid can be used as ophthalmic viscoelastic intraocular lens implantation agent, osteoarthritis and rheumatoid arthritis and other joint surgery filler, as the media is widely used in eye drops, but also for the prevention of postoperative adhesion and the promotion of skin wound healing. Hyaluronic acid formed by the reaction with other drugs to play a sustained-release effect of drug compounds can be achieved by targeted and timed-release purposes. With the development of medical technology, the application of hyaluronic acid in medicine will be more widely Edible Hyaluronic acid in the hyaluronic acid content in the human body is about 15g, in the human body's physiological activities play an important role. Skin hyaluronic acid content reduced, the skin's water-weakened, become rough and produce wrinkles; other tissues and organs of the hyaluronic acid reduction can lead to arthritis, arteriosclerosis, pulse disorder and brain atrophy. Decrease in hyaluronic acid the body will have progeria. 4, oral hyaluronic acid to increase the content of the body can complement the human body hyaluronic acid deficiencies. Hyaluronic acid by digestion, absorption, moisture make skin smooth, soft and elastic; can delay aging, prevent arthritis, arteriosclerosis, pulse disorder and brain atrophy disease from occurring. Oral hyaluronic acid will generate energy sufficient, full of youthful vitality. Oral hyaluronic acid has been widely used in Europe and the United States and other developed countries in health foods.
