• Solubility: Freely soluble in water (forms a viscous gel solution)

• Solubility in organic solvents: Insoluble

• pH (1% solution): Typically 5.0–8.0

• Form: Hygroscopic powder

Applications:

• Used in cosmetics and skincare formulations (moisturizers, serums)
• Biomedical and pharmaceutical research
• Tissue engineering and drug delivery studies
• Ophthalmic and joint-related formulations

Product Description:

Hyaluronic acid is a high molecular weight, water-soluble biopolymer widely used in cosmetic, biomedical, and research applications. Due to its exceptional water-retention and viscoelastic properties, it is valuable in skincare formulations, pharmaceutical development, and tissue engineering studies.

Storage & Handling:

• Store in a cool, dry place

• Protect from moisture

• Keep container tightly closed

• Use appropriate PPE during handling

Safety Information:

• Generally considered low toxicity
• Avoid inhalation of fine powder
• Refer to SDS for detailed handling and safety measures
