Sodium Alginate Powder is a natural polysaccharide derived from brown seaweed. It is a white to pale yellow, odorless, and tasteless powder. This versatile ingredient is widely used as a thickening, gelling, and stabilizing agent in food, pharmaceutical, and cosmetic formulations. Sodium alginate forms strong, flexible gels in the presence of calcium ions, making it indispensable in applications such as food thickening, textile printing, wound dressings, and more.
