Hyaluronic Acid Cosmetic Grade
Sodium Hyaluronate is well known as the best "Natural Moisturizing Factor". In the early 1980s, the excellent moisturizing function of Sodium Hyaluronate has been widely concerned by international cosmetics industry. With its unique film-forming and hydrating characteristics, Sodium Hyaluronate is used as a highly effective humectants in cosmetics. It attracts moisture to the skin and hold moisture in the skin, which preserve skin smoothness, suppleness and elasticity. 1 gram of HA is able to retain up to 1000 gram of water. So it is regarded as the "key to the fountain of youth". The effects are as follows: (1) Moisturizing effect Moisturizing is the most important effect of Sodium Hyaluronate in cosmetics products. It can be hydrated shell in skin surface and make the corneum hydration and softening. Compared with other humectants, Sodium Hyaluronate is less effected by the environment as it has the highest hygroscopic capacity in a relatively low humidity (e.g., in a dry winter), but has the lowest hygroscopic capacity in a relatively high humidity (e.g., in a damp summer). This unique property of Sodium Hyaluronate makes the skin adapt to different seasons. (2) Skin nutrition effect Sodium Hyaluronate is the inherent biological materials of skin. The exogenous Sodium Hyaluronate can complement the endogenous Sodium Hyaluronate. Low molecular Sodium Hyaluronate can penetrate into dermis directly to improve the nutrient supply. (3) Skin repair effect There is some evidence that topically applied Sodium Hyaluronate can reduce skin irritation from various causes. During clinical trials it was also shown that this ingredient is effective in promoting healing and fighting inflammatory conditions of the skin. Sodium Hyaluronate serves as a free radical scavenger and antioxidant, helping to protect the skin from the aging effects of excessive sunlight exposure. (4) Emollient and Film-forming Sodium Hyaluronate is high polymer with high lubrication and film-forming. Sodium Hyaluronate contained in cosmetics creates protective film on the surface of skin, which retains moisture, and at the same time prevents moisture in the skin from evaporation, so that improves freshness of the skin. (5) Thickening Sodium Hyaluronate solution have high viscosity, and 1% solution is gelatinous. It can be added to cosmetics to improve the thickening and stability.ItemStandardAppearanceWhite powderGlucuronic Acid≥ 44%Sodium Hyaluronate≥ 91%Appearance of SolutionA600nm≤ 0.01Nucleic AcidA260nm≤ 0.5pH5.0-8.5Molecular Weight0.8-1.5 Million Da.1.5-1.8 Million Da.8000-15000 Da.Protein ≤0.05%Loss on drying≤10.0%Residue on Ignition≤20.0 %Chlorides≤ 0.5%Iron≤ 80ppmHeavy metal≤10ppmArsenic≤2ppmBacteria Count≤100CFU/GMolds & Yeast≤10CFU/gStaphylococcus aureusNegativePseudomonas aeruginosaNegativeHemolysisNegativeViable Hemolytical StreptococciNegativeProduct FeaturesOriginal bacteria name: Streptococcus ZooepidemicusMade by fermentation Molecular Weight (Dalton): 1.
