Key Benefits & Product Features
1.Superior Moisturizing Power: Retains up to 1000× its weight in water, forming a strong hydrating network that keeps skin soft, plump, and hydrated.
2.Barrier Protection: Creates a breathable film that prevents moisture loss and shields the skin from pollution and UV-induced damage.
3.Excellent Compatibility: Compatible with glycerin, peptides, surfactants, botanical extracts, and other active ingredients across a wide pH range.
4.Outstanding Stability: Batch-to-batch viscosity stability; no degradation after 5 days at room temperature.
5.High Purity & Low Impurities: Glucuronic acid content >46%, sodium hyaluronate purity 97–99%, exceeding international standards.
6.Non-Irritating & Safe: pH maintained between 6.0–7.0; protein content <0.05%; suitable for sensitive-skin formulations.
7.Transparent Appearance: Dissolves into a clear, colorless solution, unlike inferior products that turn yellowish or cloudy.

Why Choose Hyaluronic Acid
1.Measured Molecular Weight Assurance: Each batch labeled with actual measured values (not just range) for precise formulation design.
2.Consistent Quality: Stable performance across batches verified through viscosity and pH comparison testing.
3.Advanced Filtration Technology: Proprietary purification eliminates black specks and residues, ensuring visual and structural purity.
4.Proven Safety: Manufactured under aseptic conditions with rigorous microbial control and validated low endotoxin levels.
5.High Transparency & Clean Dissolution: Superior optical clarity ensures excellent visual quality and product aesthetics.

How to Judge High-Quality Sodium Hyaluronate
1.Visual Purity: Fine, pure white powder with no visible black dots or discoloration.
2.Microbial Control: Produced under sterile conditions with strict CFU standards.
3.Particle Fineness: Uniform granules indicate controlled dehydration; coarse particles suggest poor processing.
4.Solution Clarity: High transparency reflects high purity and excellent light transmittance.
5.Glucuronic Acid Level: Higher content correlates with better moisturizing capability.
6.Protein Content: Should be <0.05% to minimize allergenic potential.

Usage & Handling Guidelines
1.Dissolution: Use purified or distilled water to maintain clarity and purity.
2.Preservation: Once dissolved, add preservatives if not used immediately to avoid microbial growth.
3.Compatibility: Avoid cationic surfactants or preservatives to prevent precipitation.
4.Storage: Keep sealed in a cool, dry place (2–8°C), away from humidity and direct sunlight.

Frequently Asked Questions (FAQ) – High Molecular Weight Sodium Hyaluronate

1. What is High Molecular Weight Sodium Hyaluronate (HMW-HA)?
High Molecular Weight Sodium Hyaluronate is a premium-grade form of hyaluronic acid with a molecular weight of 1800kDa–2500kDa. It is widely used in cosmetics and skincare for long-lasting hydration, skin barrier protection, and elasticity improvement.

2. What are the benefits of HMW-HA for the skin?
HMW-HA forms an elastic, breathable moisture film on the skin, providing continuous hydration, improving elasticity, protecting against environmental irritants, and supporting overall skin health.

3. How is HMW-HA different from low or medium molecular weight hyaluronic acid?
High molecular weight HA primarily stays on the skin surface, creating a moisture barrier and protecting against water loss, while low molecular weight HA penetrates deeper to support skin regeneration. HMW-HA is ideal for surface hydration and barrier protection.

4. Which cosmetic products can use HMW-HA?
HMW-HA is suitable for a wide range of skincare and personal care products, including:

• Moisturizing creams & lotions

• Serums & ampoules

• Sunscreens & UV-protection products

• Haircare formulations

5. Is HMW-HA safe for sensitive skin?
Yes. HMW-HA is biocompatible, non-toxic, and gentle on the skin. Produced under ISO9001, HACCP, GMP, and ISO14001 certified facilities, it meets international cosmetic safety standards.

6. How should HMW-HA be stored?
Store in a cool, dry place, away from direct sunlight and moisture. Keep the container tightly closed to maintain stability and prevent contamination.

7. How do I use HMW-HA in formulations?
HMW-HA can be dispersed in water or aqueous solutions. It is recommended to hydrate fully before blending into final formulations to achieve optimal viscosity and moisturizing performance.

8. Can HMW-HA improve UV protection or repair?
Yes. HMW-HA enhances the skin’s natural barrier, helping reduce UV-induced moisture loss and supporting skin repair mechanisms when combined with other protective ingredients.

9. What certifications does your HMW-HA have?
Our HMW-HA is produced in ISO9001, HACCP, GMP, and ISO14001 certified facilities, ensuring high purity, consistency, and safety suitable for international cosmetic and pharmaceutical applications.

10. Is HMW-HA suitable for B2B cosmetic manufacturing?
Absolutely. Its high-quality, stable, and standardized properties make it ideal for global cosmetic brands and professional skincare formulations.
