Plant Description: Plant origin: Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed Of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc. The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a new biological at home and abroad. Its molecular weight is from several ten thousand to several million. It’s aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food.
1. Moisturizing is hyaluronic acid’s most important function.. Hyaluronic acid has the capacity to keep good water retention automatically depending on the change of the surrounding humidity. 2. Hyaluronic acid can penetrate through the surface of the skin and accelerate the nutritional supply of the skin metabolism, so that it can prevent the skin from ageing.
3. Hyaluronic acid has a high viscosity in solution. 1% solution has the appearance of gel. It is used in cosmetic preparation as a thickener and stabilizer.
4. As a high molecular weight polymer, hyaluronic acid has strong lubricating and film-building properties. The skin-care cosmetics with hyaluronic acid as an ingredient have outstanding lubricating capability. While applied to the skin it can make the skin soft, smooth, moist and elastic and protect the skin from external injuries. Hair care products contain hyaluronic acid may form a film layer to keep the hair moist and lubricating. It also may prevent the hair from being electrostatic charged, so that hair can be combed more easily and smoothly.
