Description

Chondroitin Sodium Salt is a highly purified, sulfated glycosaminoglycan derived from animal cartilage, widely recognized for its role in maintaining the structural integrity and elasticity of connective tissues. This compound is a critical raw material for the nutraceutical and pharmaceutical industries, valued for its chondroprotective and anti-inflammatory properties. It is essential for manufacturers of joint health supplements, ophthalmic solutions, and advanced biomaterials for tissue engineering and drug delivery systems.

Application

• Dietary Supplements & Nutraceuticals: Primary ingredient in oral formulations (tablets, capsules, powders) for joint health, osteoarthritis management, and overall cartilage support.
• Pharmaceuticals: Used in the formulation of prescription drugs for osteoarthritis, as well as in ophthalmic solutions for dry eye syndrome and corneal protection.
• Veterinary Medicine: Incorporated into feed additives and injectables for companion animals and livestock to support joint and bone health.
• Cosmeceuticals: Active component in topical creams, serums, and anti-aging formulations for its skin-hydrating and tissue-repairing benefits.
• Biomedical Research & Biomaterials: Serves as a key component in hydrogels, scaffolds for tissue engineering, and coatings for medical devices to enhance biocompatibility.
• Functional Foods & Beverages: Fortified into health drinks, dairy products, and snacks to provide joint health benefits.

Quality Control

Our Chondroitin Sodium Salt is manufactured under strict quality management systems. We offer grades compliant with major international pharmacopeial standards, including USP, EP, and JP, as well as food-grade specifications (FCC). Every batch undergoes rigorous identity, purity, and safety testing, including assays for potency, sulfate content, and limits on impurities. Certificates of Analysis (COA) detailing all specifications are available upon request.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a low-humidity environment to prevent caking and degradation. Keep away from strong oxidizing agents.
