Sodium stearate is widely used as a thickening agent and stabilizer in the production of soaps and cosmetics. It helps to create a rich lather in soaps, making them more effective at cleaning. In cosmetics, it acts as an emulsifier, ensuring that oil and water-based ingredients mix well, providing a smooth texture to products like lotions and creams. In the pharmaceutical industry, it serves as a lubricant in the manufacturing of tablets, preventing them from sticking to the machinery during production. It also aids in the even distribution of active ingredients. Additionally, sodium stearate is used in the food industry as an anti-caking agent, preventing powders like flour and spices from clumping together. It is also employed in the production of certain types of candles, where it helps to harden the wax and improve burning quality.
