Cost-efficient high-molecular-weight hyaluronic acid powder for water-based hydration, light gel body and economical cosmetic formulas.
Hyaluronic Acid (China) is a cosmetic hyaluronic acid powder for water-based moisturising formulas.
This grade is Sodium Hyaluronate grade hyaluronic acid with molecular weight 0.8M-2.0M Da. It is designed for cost-efficient hydrating formulas that still need standard high-molecular-weight HA performance.
Molecular weight strongly changes how hyaluronic acid behaves in a formula: lower molecular weight grades give a lighter skin feel, while higher molecular weight grades contribute more surface hydration, viscosity and film feel.
Product Description: This China grade is positioned for cost-sensitive formulas that need a standard hyaluronic acid powder for surface hydration, water binding and light gel body. It is a practical choice for rinse-off support products, masks, body gels, economical serums and other formulas where cost control is important.
COA specification includes sodium hyaluronate minimum 93%, glucuronic acid minimum 45%, transparency minimum 99% in 0.1% solution, pH 5.0-7.5 and molecular weight 0.8M-2.0M Da.
When the formula is not already preserved, add an appropriate preservative system. Hydrated hyaluronic acid gels are water-rich systems and can lose viscosity or become contaminated without preservation.
Usage: Suitable for hydrating serums, gels, lotions, creams, masks, essences and other water-phase cosmetic products.
Mixing method:
- Disperse slowly into the water phase while mixing. Sprinkle onto the water surface gradually to avoid clumps.
- For small lab batches without a homogenizer, shake or mix well, then allow time for full hydration before final viscosity adjustment.
- Maintain final formula pH about 3-9 and avoid unnecessary high heat or excessive shear after hydration.
Usage rate: 0.1-0.5%
Product characteristics: White powder, molecular weight 0.8M-2.0M Da.
Solubility: Water soluble. Hydration is easier when the powder is added slowly into a moving water phase.
Storage: Keep tightly closed in a cool, dry place away from sunlight and heat. For long-term storage, refrigeration is acceptable when condensation is avoided.
