Description

Hyaluronic Acid is a high-molecular-weight, naturally occurring glycosaminoglycan renowned for its exceptional water-binding capacity and viscoelastic properties. This makes it a critical functional ingredient for applications demanding superior moisture retention, lubrication, and structural support. It is an essential raw material for manufacturers in the pharmaceutical, advanced dermal fillers, premium skincare, and nutraceutical industries. Our supply of Hyaluronic Acid CAS NO 9004-61-9 is characterized by consistent purity and reliable performance.

Application

• Dermal Fillers & Aesthetic Medicine: Primary component in injectable gels for facial contouring and wrinkle correction.
• Ophthalmic Surgery: Used as a viscoelastic protector in cataract and other intraocular procedures.
• Advanced Topical Skincare: Key moisturizing agent in serums, creams, and masks for intense hydration and barrier repair.
• Orthopedic Injections (Viscosupplementation): Administered intra-articularly to alleviate pain and improve mobility in osteoarthritic joints.
• Nutraceuticals & Dietary Supplements: Incorporated for promoting joint health, skin hydration, and overall wellness.
• Wound Healing Formulations: Utilized in gels and dressings to create a moist environment conducive to tissue repair.
• Drug Delivery Systems: Serves as a biodegradable carrier for controlled and targeted release of therapeutic agents.

Quality Control

Our Hyaluronic Acid is produced and tested under strict quality management systems. We offer grades compliant with relevant pharmacopeial standards, including USP and EP, where applicable. Every batch is subjected to rigorous analytical testing for identity, purity, molecular weight distribution, and microbiological quality. Certificates of Analysis (COA) documenting all critical parameters are available upon request to ensure full traceability and regulatory support.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability of certain high-purity grades, storage at 2-8°C is recommended. Keep the container tightly sealed when not in use to prevent moisture absorption.
