Chondroitin Sulfate Sodium (sometimes spelled Chondroitin Sulphate Sodium) is the sodium salt of a sulfated glycosaminoglycan (GAG). It is a complex macromolecule naturally extracted from animal cartilage, such as bovine, porcine, avian, or marine (shark) tissues. Its CAS number is 9007-28-7.

It appears as a white to off-white, odorless, and highly hygroscopic powder. It is internationally recognized as a critical structural component of extracellular matrixes, particularly in joint cartilage.

Applications

1. Pharmaceuticals and Dietary Supplements

Joint Health & Osteoarthritis: It is most widely used in combination with Glucosamine and MSM (Methylsulfonylmethane) to treat or prevent osteoarthritis. It helps reduce joint pain, improve joint mobility, and slow down the progression of joint space narrowing.

Prescription Drug Status: While sold as a dietary supplement in the US and China, high-purity Chondroitin Sulfate Sodium is approved as a prescription drug (SYSADOA - Symptomatic Slow-Acting Drug for Osteoarthritis) in several European countries.

2. Ophthalmic Medical Devices

Viscoelastic Solutions: Due to its excellent viscosity and cell-protective properties, it is used alongside hyaluronic acid in ophthalmic surgical solutions. It protects delicate corneal endothelial cells during cataract surgery and corneal transplantation.

Dry Eye Drops: It serves as a lubricant in advanced eye drops to stabilize the tear film and relieve severe dry eye symptoms.

3. Cosmetics and Personal Care

Skin Conditioning: In skincare, it acts as an advanced humectant and film-forming agent. It hydrates the skin matrix, promotes tissue repair, and enhances the soothing properties of anti-aging or barrier-repair creams.

Made of pure aluminum composite material, with high barrier properties, effectively isolating it from air, moisture, and light.
Completely moisture-proof, oxidation-resistant, and anti-caking, ensuring long-term preservation of powder purity.
Individually sealed and packaged; sizes can be customized in 1kg/5kg/10kg/25kg bags.
Neutral, unlabeled packaging and printing of customer logos and product information are also supported.

The independent and professional raw material storage workshop is kept at a constant temperature, dry and protected from light throughout, with ventilation, moisture control, and humidity prevention to prevent powder from absorbing moisture, clumping, deterioration, and oxidation. The workshop features zoned shelving for vertical storage, with cartons and drums stacked in separate zones to keep goods off the ground and away from moisture, acids, alkalis, odors, and sources of pollution.
