Hydrolyzed Sodium Hyaluronate is produced by enzymatic degradation thus resulting in higher purity, high anti-oxidant activity, high moisture retention, and high capacity for sun repair. The low molecular weight penetrates the skin and nourishes it deeply. It exhibits quick penetration with deep nourishment. It has high capacity for sun repair and has low hygroscopic potential in relatively high humidity. Imparts softness, supple feel and moisture to the skin.

Hydrolyzed sodium hyaluronate is an ultra-low molecular weight hyaluronic acid, designed for better skin penetration. With its characteristic advantage, Hydrolyzed sodium hyaluronate maximizes skin moisturizing and activates the function of stemness in the epidermis and promotes cell differentiation, preventing skin aging.

Hydrolyzed sodium hyaluronate can penetrate through skin deeply and rapidly, which will give new features to cosmetics, including raising HA content in the skin, deep hydrating, activating the skin, anti-aging, anti-oxidation, repairing skin damage, and deeply moisturizing, etc.

Hydrolyzed sodium hyaluronate can be applied in a series of products, such as eye cream, eye shadow, serum, moisturizing cream, sunblock cream, BB cream, lipstick, cleanser, toner, moisturizer, facial mask and scrub, emulsion, lotion, gel, foundation, blush, hydrating gels, bodycare products, haircare products.

Detailed functions of hydrolyzed sodium hyaluronate
1. Moisturizing
HA holds more water than any other molecule in the body and is necessary to keep collagen hydrated and youthful.
2. Lubrication and film formation
hydrolyzed sodium hyaluronate is a high molecular weight polymer with strong lubricating and filming. When it is smeared on the skin it can form a film and make the skin feel lubricating. Film formed on the surface of the hair can moisturize and lubricate the hair and eliminate static electricity. The hair becomes soft and easy to comb.
3. Injured-skin repairing and preventing
1) Accelerate the skin regeneration of injury by promoting proliferation and division of cuticle cells, and clear away oxygen free radical.
2) When formulated with EGF and Heparin, it can accelerate the regeneration of cuticle cells, keep skin delicate, smooth and elastic.
3) Prevent skin from being injured, relieve pain and accelerate wound healing of scald and burn. Low molecular weight sodium hyalurate is significant helpful for the healing of erythema and trauma on the skin.
4. Nutrition
Low molecular weight sodium hyalurate can reach the corium layer so as to improving the content of water,nourishing skin and expanding blood capillary, improving microcirculation and promoting absorption of nutriment. So the skin will be smooth, elastic and not easy to age.

Hydrolyzed sodium hyaluronate as a safe and effective cosmetic ingredient has many advantages as following:
1,Transdermal absorption: Hydrolyzed sodium hyaluronate can penetrate into the skin with an absorption rate that can reach 69.5%.
2,Repairing damaged cells:Hydrolyzed sodium hyaluronate can repair the skin cells damaged by ultraviolet irradiation, increase cellular activity and cellular proliferation.
3,Scavenging free radicals: Hydrolyzed sodium hyaluronate can effectively scavenge Reactive Oxygen Free Radicals (ROS) induced by ultraviolet irradiation, so it can slow down the skin aging process by good anti-oxidation capability.
4,Deep moisturizing: Hydrolyzed sodium hyaluronate can penetrate into the skin, hydrating the epidermis and dermis. HA with high molecular weight has also good moisturizing capability by forming a film on the surface of skin. When Hydrolyzed sodium hyaluronate and HA with high molecular weight are used in formulation together a remarkable synergistic effect is observed.
5,Anti-aging: Hydrolyzed sodium hyaluronate can significantly enhancing skin elasticity, strengthening the skin barrier, reducing skin wrinkles.

Remarks
1.Use pure water or distilled water to dissolve to guarantee the fine transparency.
2.Heating can accelerate the dissolution of HA.
3.Hydrolyzed sodium hyaluronate is a kind of biological polysaccharide. It is better to be used up once be dissolved. If there is much left, please store it with preservative to avoid microbial pollution.
4.Hydrolyzed sodium hyaluronate should not be used together with cationic emulgator or cationic preservative at the same time. Failure to do so may result in turbid or precipitate.
5.Hydrolyzed sodium hyaluronate is very hygroscopic, so it should be stored air tightly in a dry and low temperature (2-10 ) place.
6. Much better skincare efficacy can be obtained when combined with common HA.
