Potassium hyaluronate

Potassium hyaluronate (CAS 31799-91-4), also known as hyaluronic acid potassium salt, is the potassium salt form of hyaluronic acid used as a humectant and film-forming agent in cosmetic and pharmaceutical formulations.

Where is Potassium hyaluronate used?

• Skincare: serums, creams, sheet masks for surface hydration and improved skin texture without occlusive agents
• Ophthalmic: eye drops and contact lens solutions where potassium ion compatibility with tear fluid matters
• Topical gels and pharmaceutical carriers: viscosity modifier controlling rheology in semi-solid systems
• Biotech and tissue engineering: scaffold component or cell culture additive requiring defined ionic composition
• It attracts and retains moisture in skin and mucous membranes, suiting sodium-free or low-sodium formulations.

Good to know: Buyers should confirm molecular weight distribution and purity specification when sourcing for regulated end-use applications.

Commercial specifications

• Molecular weight ranges differentiated as low, medium, and high to match viscosity and penetration requirements
