Sodium Hyaluronate is the sodium salt of Hyaluronic Acid, a glycosaminoglycan consisting of D-glucuronic acid and N-acetyl-D-glucosamine disaccharide units. It exists in humans and animals, and is found in high concentrations in intercellular substance, eye vitreous, umbilical cord, skin, Synovial fluid and rooster/cock comb, and many other soft connective tissues.
Application:
The bacteria used for the fermentation is non-GMO and non-hemolytic. Fermentation takes place in a plant-based growth medium without any animal products or byproducts. Sustainable, 100% Vegan and Vegetarian.
Difference between high and low molecular weight:
It is very important to note that there are two types of hyaluronic acid available to cosmetic formulators – HIGH MOLECULAR WEIGHT (the most common), and LOW MOLECULAR WEIGHT Hyaluronic Acid.
Most cosmetic manufacturers make use of high molecular weight HA. This ingredient, when used at optimal levels of inclusion, is an incredibly effective moisture-binding element, providing superficial hydration of the epidermis for many hours. However, this ingredient is a macro-molecule and is too large to penetrate into the deeper layers of the skin.
Low molecular weight HA, on the other hand, has been engineered to exist as a far smaller molecule that is able to penetrate through the epidermis to provide deep hydration. It has been scientifically proven that increased levels of hyaluronic acid in the deeper layers of the skin actually stimulate the production of collagen fibres, which in turn will result in a firmer, more toned appearance.
Sodium Hyaluronate is a advanced biological product with a wide range of molecular weights from thousands up to millions Dalton.
Its water solution has a very highmoisture retention, viscoelasticity and lubricity. It can be widely used in
cosmetics(creams,face mask etc.), health food and other industries.
Function :
1. Moisturizing and film-forming properties
2. Anti-Wrinkles
3. Anti-Irritation
4. Nutrition delivery
5. Free radical scavenging
6. Moisture retaining,skincare water absorption
