Sodium Hyaluronate Powder is a straight chain macromolecular mucopolysaccharide composed of repeat disaccharide units of glucuronic acid and N-acetylglucosamine.
It's molecular weight is from several ten thousand to several million. It's aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. Pure Hyaluronic Acid is widely used in cosmetics, health and beauty food.

| High Molecular Weight | 1,500,000 - 2,200,000 Dalton; More than 2,200,000 Dalton |
Excellent lubrication and film-forming properties, moisturising, sun protection, thickening and stabilising emulsification. |
Hyaluronic acid is a natural biological molecule widely existing in skin and other tissues, which has excellent moisturizing effect and is internationally known as the ideal natural moisturizing factor. It is the best moisturizing substance found in nature for cosmetics.
Hyaluronic acid can also promote the proliferation and differentiation of epidermal cells, remove oxygen free radicals, and prevent and repair skin damage. The aqueous solution of hyaluronic acid has a high viscosity, which can thicken the water phase. After emulsifying with oil phase, the paste is uniform and fine, and has a stable emulsification effect.
Hyaluronic acid is the best natural moisturizing ingredient for high-grade cosmetics. It has good compatibility and can be added to almost any beauty cosmetics. It is widely used in creams, lotions, toners, serums, facial cleansers, bath fluids, hair shampooers, mousses, lipsticks and other cosmetics.
| Type | Molecular Weight Range | Effect | Application |
|---|---|---|---|
| High molecular sodium hyaluronate | 1.5m - 2.0m | Excellent lubricity and film formation; Moisture retention; Sun protection; Thickening and stabilizing emulsification | Serum, lotion, face cream, Sunscreen, Gel |
| Middle molecule sodium hyaluronate | 0.5m - 0.8m, 0.8m - 1.5m | Nourish skin and moisturize for a long time | Serums, lotions, creams, gels |
| Low molecular weight sodium hyaluronate | 8k - 50k, 0.1m - 0.5m | Transdermal absorption, deep moisture, anti-aging, Post-sun repair | Toner, essence, Lotions, creams, masks |
| Low molecular weight sodium hyaluronate | 3k - 5k | Low viscosity, fast penetration, deep moisture, anti-aging, post-sun repair | Toner, essence, Lotions, creams, masks |
Polymer: Can form a breathable film on the skin surface, make the skin smooth and moist, and can block foreign bacteria, dust, ultraviolet invasion, protect the skin from damage. High molecular hyaluronic acid is better at retaining water, but it is less absorbed by the skin than low molecules.
Low molecule: It can penetrate into the dermis, slightly dilate capillaries, increase blood circulation, promote metabolism, and improve skin nutrient absorption. That is, low molecular hyaluronic acid is easily absorbed by the skin, but the water retention ability is less.

The content of hyaluronic acid in the human body is about 15g, which plays an important role in the physiological activities of the human body. Decreased hyaluronic acid content in the skin weakens water retention, causing rough skin and wrinkles. In other organs, decreases can lead to arthritis, arteriosclerosis, pulse disorders, and brain atrophy. Supplying hyaluronic acid orally supplements this loss, keeping the skin moist, smooth, soft and elastic while delaying aging and helping prevent joint and vascular issues.

Sodium Hyaluronate Powder is a straight-chain macromolecular mucopolysaccharide composed of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It is highly valued in cosmetics, health, and beauty foods for its outstanding moisture retention, high viscoelasticity, and excellent lubricity.
High molecular weights (1.5M - 2.2M+ Dalton) form a breathable protective film on the skin surface to block pollutants and lock in moisture. Low molecular weights (under 50k Dalton) easily penetrate into the dermis layer, slightly dilating capillaries to increase blood circulation, promote metabolism, and deeply moisturize the skin.
Cosmetic grade Sodium Hyaluronate acts as an ideal natural moisturizing factor. It promotes epidermal cell proliferation, removes oxygen free radicals, repairs skin damage, thickens formulation phases, and stabilizes emulsification in creams, lotions, and serums.
Oral consumption of food grade Hyaluronic Acid supplements the natural depletion that occurs with age. It helps restore skin elasticity, lubricates joints to improve bone density, protects gastric mucosa, and supports overall cardiovascular health.
For skincare and cosmetic applications, the typical suggested dosage is 0.1–0.5% for solid formulations and 10–50% for liquid products. It should be dissolved in water; higher molecular weights dissolve slower, but heating can be applied to accelerate the process.
Small quantities (1kg) are packed in dual plastic bags inside aluminum foil bags and boxes. Larger amounts (10kg, 25kg+) are delivered in drums or cartons with double plastic linings. Shipping options include express air delivery (DHL, Fedex, UPS) for smaller batches and air or sea freight for quantities exceeding 100kg.
