description Product Description
Sodium alginate is widely used in the food industry as a thickening, stabilizing, and gelling agent. It is commonly found in products like ice cream, yogurt, salad dressings, sauces, jelly, and candies to improve texture, prevent separation, and provide a flexible, smooth consistency.
In the pharmaceutical industry, it is utilized in wound dressings, drug delivery systems, tablet formation, coatings for controlled drug release, and oral care products such as toothpaste and mouthwash due to its biocompatibility, gelling ability, and viscosity-enhancing properties.
Sodium alginate is also employed in the textile industry for printing and dyeing fabrics, providing better color fixation. Additionally, it plays a role in biotechnology for cell encapsulation and tissue engineering, offering a supportive matrix for cell growth.
In cosmetics, it serves as an ingredient in skincare products and face masks to hydrate the skin and improve product texture. Its water-absorbing and flocculating properties make it useful in water treatment, dental impressions, and as a mold-making material in various industries.
