What are the benefits of stearic acid in the formulation

What is the difference between acids and fatty acids?
Despite the acid in their name, fatty acids are very different from acids. Fatty acids are the basic components of fats and oils. Unlike acids, they moisturize the skin more gently.
What are the benefits of stearic acid in the formulation?
Stearic acid is mainly used as a surfactant, emulsifier and thickener in cosmetics and skincare products.
Surfactant
Surfactant is short for surfactant. Surfactants are compounds that reduce the surface tension between two substances, helping them mix or moisturize skin evenly.
Another function of the surfactant is to remove oil and emulsify the grease, suspending the dirt and allowing it to be washed away. This is possible because the surfactant molecules are attracted to water at one end and oil at the other. So the surfactant picks up the oil, dirt, and other impurities that have accumulated on the skin during the day and wash them off. Because of these properties, stearic acid can be found in many different face cleansers and body washes.
Emulsifier
Stearic acid can also be used as an emulsifier. Products that contain both water and oil require emulsifiers. In formulations, water and oil-based components are often separated. Emulsifiers help keep them mixed and prevent the components from splitting or separating. This helps stabilize and improve the life of your products.
Stearic acid, as an emulsifier, consists of a hydrophilic head and an oil-philic tail. The hydrophilic head is attracted to the water-based component, while the hydrophobic tail is attracted to the oil-based component, pulling them together and preventing separation.
Texture
Another characteristic of stearic acid is that it can be used as a thickening agent or hardener. That's why stearic acid is added to soaps, candles, plastics, crayons, and more. It helps to harden the product and also helps to keep its shape.
