Food Industry: In addition to the applications mentioned above, it is widely used in meat products as a water-retaining agent and binder, improving the water retention and elasticity of meat products. In baked goods, it can increase the toughness and extensibility of dough, improving the quality of baked products.
Pharmaceutical Industry: It can be used as a drug carrier in the preparation of sustained-release and controlled-release formulations, controlling the release rate of drugs and prolonging their duration of action. It can also be used to make wound dressings, as its good biocompatibility and water absorption promote wound healing and prevent wound infection.
Cosmetic Industry: In cosmetics, sodium alginate is often used as a thickener, stabilizer, and moisturizer. For example, adding sodium alginate to products such as face masks, lotions, and creams increases the viscosity of the product, retains moisture, and keeps the skin moist and smooth.
Printing and Dyeing Industry: As a printing paste for reactive dyes, sodium alginate has good fluidity and permeability, allowing dyes to adhere evenly to fabrics, improving the clarity and color vibrancy of prints. Furthermore, it is easy to wash off and will not leave residue on fabrics.
Paper Industry: In the papermaking process, sodium alginate can be used as a surface sizing agent and paper strengthening agent to improve the strength, abrasion resistance, and water resistance of paper, and enhance its printability.
