Description

Hyaluronic Acid Potassium Salt is a high-purity, water-soluble derivative of hyaluronic acid, a naturally occurring glycosaminoglycan. This potassium salt form offers enhanced stability and solubility, making it a critical functional ingredient for advanced formulations. It is essential for manufacturers in the cosmetic, pharmaceutical, and nutraceutical industries seeking superior moisturizing, viscoelastic, and skin-repair properties.

Application

• Cosmetic & Skincare Formulations: As a premium humectant and moisturizer in serums, creams, lotions, and anti-aging products for deep hydration and improved skin elasticity.
• Injectable Dermal Fillers & Medical Devices: A key component in cross-linked gels for soft tissue augmentation, joint lubrication (viscosupplementation), and ophthalmic surgeries.
• Nutraceuticals & Dietary Supplements: Used in oral supplements targeting joint health, skin hydration, and overall connective tissue support.
• Advanced Wound Care: Incorporated into hydrogels and dressings to promote a moist healing environment and support tissue regeneration.
• Ophthalmic Solutions: As a viscoelastic agent in eye drops and surgical aids to protect corneal tissues and maintain ocular surface lubrication.
• Biomedical Research & Cell Culture: Serves as a scaffold material in 3D cell culture, tissue engineering, and drug delivery system development.
