description Product Description
Used extensively in the manufacturing of paper and pulp, it helps break down wood fibers to produce paper products. It is also a key ingredient in the production of detergents and soaps, where it saponifies fats and oils to create cleaning agents. In the chemical industry, it serves as a strong base for various synthesis processes, including the production of plastics and textiles. Additionally, it is employed in water treatment to adjust pH levels and remove heavy metals. In the food industry, it is used for curing and peeling fruits and vegetables, as well as in the production of cocoa and chocolate. It also plays a role in biodiesel production by catalyzing the transesterification of fats and oils.
