Description

Sodium Hyaluronate is the sodium salt of hyaluronic acid, a naturally occurring glycosaminoglycan renowned for its exceptional water-binding capacity and viscoelastic properties. This high-purity biopolymer is critical for applications demanding superior moisture retention, lubrication, and structural support. It serves as a fundamental ingredient for manufacturers in the cosmetic, pharmaceutical, nutraceutical, and medical device industries seeking to enhance product performance and efficacy.

Application

• Dermal Fillers & Medical Devices: A key component in injectable fillers for soft tissue augmentation and in ophthalmic surgery viscoelastic devices.
• Cosmetic & Skincare Formulations: Used in serums, creams, and masks as a powerful humectant to hydrate, plump, and improve skin barrier function.
• Pharmaceuticals: Employed in topical formulations for wound healing, as a lubricant in eye drops, and in drug delivery systems for controlled release.
• Nutraceuticals & Dietary Supplements: Incorporated into oral supplements for joint health and hydration support.
• Advanced Biomaterials: Utilized in the research and development of hydrogels, 3D bioprinting, and tissue engineering scaffolds.

Quality Control

Our Sodium Hyaluronate is produced under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for purity, molecular weight, and microbiological quality. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP, JP) based on grade. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metals, endotoxin levels (where applicable), and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture absorption and caking.
