Physicochemical Properties

Applications

1. Cosmetics & Personal Care

• Moisturizing and anti-aging serums
• Face creams, lotions, masks and eye creams
• Toners, essences and ampoules
• Hair care products (conditioners, leave-on treatments)

Key functions:

• Strong humectant: binds large amounts of water to the stratum corneum
• Film-forming: creates a breathable, protective layer, improving skin elasticity and smoothness
• Sensory enhancement: adds slip and richness, especially in water-based systems

2. Pharmaceutical & Medical Uses

• Ophthalmic solutions, eye drops and intraocular viscoelastic agents
• Intra-articular injections for joint lubrication and osteoarthritis support
• Wound dressings, tissue-engineering scaffolds and topical gels

Here, sodium hyaluronate contributes:

• Lubrication and shock absorption in joints
• Space-maintaining and protective functions in eye surgery
• Moist wound-healing environment and cell-friendly matrix support

3. Nutraceuticals & Dietary Supplements

• Skin beauty and hydration capsules, powders and drinks
• Joint-health formulations often combined with collagen, chondroitin or MSM

4. Other Uses

• Biomedical and cell-culture applications as extracellular matrix component
• Viscosity modifier and stabilizer in specialized formulationsAbcam+1

Storage Conditions

To maintain quality throughout shelf life:

• Store in a cool, dry, well-ventilated place, away from sources of heat and moisture.
• Recommended storage temperature: ≤ 25 °C, preferably 2–8 °C for long-term stability.
• Keep in tightly sealed original packaging; protect from direct sunlight and strong odors.
• After opening, reseal promptly and consume as soon as possible, or re-pack under dry, inert conditions if necessary.

Safety Precautions

Sodium hyaluronate is generally considered to have low acute toxicity and good biocompatibility, but it should still be handled as an industrial chemical.

Dispose of material in accordance with local regulations and refer to the product’s official SDS for detailed safety and regulatory information.

Avoid creating dust; do not breathe dust or aerosols.

Use appropriate personal protective equipment: gloves, lab coat, safety glasses, dust mask or respirator in dusty environments.

Avoid contact with eyes and prolonged contact with skin.

In case of contact with eyes, rinse immediately with plenty of water and seek medical attention if irritation persists.

In case of accidental ingestion, rinse mouth and seek medical advice if necessary.

Spillage: sweep up carefully to avoid dust, collect in suitable container for disposal, and ventilate area.
