Hyaluronic acid

Hyaluronic acid (CAS 9004-61-9), also known as HA, is a naturally derived polysaccharide used in cosmetic, pharmaceutical and biotech manufacturing. Also marketed as Luronit and Sepracoat.

Where is Hyaluronic acid used?

• Skincare and topical cosmetics: humectant in serums, creams and sheet masks for surface hydration across molecular weight grades
• Pharmaceutical: viscoelastic agent in ophthalmic solutions and carrier matrix in injectable joint therapy formulations
• Wound care and medical device coatings: biocompatible hydrating layer for tissue contact
• Biotech and life science: scaffold component in cell culture media and tissue engineering substrates
• It acts as a viscosity modifier in formulations requiring sustained moisture retention and texture control.

Good to know: Sodium hyaluronate is the most commercially prevalent salt form. Standard grades include cosmetic, food-grade and pharmaceutical-grade (USP/EP), with molecular weight ranges specified to match application requirements.

Commercial specifications

• Molecular weight ranges: low, medium and high
• Bulk quantities and smaller research and pilot-scale packaging
