Application

1. One of the main uses of stearic acid is emulsification. As such, it is often added to a wide range of products such as cosmetics, foods and pharmaceuticals. When mixed with water, it can help create a stable emulsion by acting as a surfactant. This property allows it to be used in a wide variety of products: from lotions and creams to margarine and ice cream.

2. Stearic acid is also an excellent lubricant and is used in various industries. For example, it is used as a lubricant in manufacturing processes where high levels of friction and heat are generated, such as in the production of plastics and rubber. It is also used in candle making, where it helps create a slow-burning, long-lasting flame.
