Sodium Alginate is a natural polysaccharide extracted from brown algae, white to light yellow powder forming gels with calcium ions, highly viscous in aqueous solutions. It offers stabilizing and thickening functions in food and pharma, with food-grade variants compliant with FDA inactive ingredient lists and PubChem polymer records.
Sodium Alginate
Employed as a gelling agent in restructured foods like pimento olives; in pharmaceutical capsules for controlled release; in wound dressings for moisture retention; in textile printing for dye fixation; and in dairy products for texture improvement.
Generally safe but dust may cause respiratory irritation; gel hazards if ingested dry leading to blockage. Low allergenicity; avoid high concentrations in sensitive applications; use masks during powder handling per Sigma-Aldrich safety data.
Supplied in 20 kg fiber drums with inner aluminum foil liners for light protection. Maintain cool, dry storage facilities with humidity controls to prevent clumping.
