Stearic acid

Stearic acid is a type of naturally occurring fat called a saturated fatty acid, found in animal fats and some plant fats like cocoa butter and shea butter. It has a long chain of carbon and hydrogen atoms, making it solid at room temperature. In the skincare industry, stearic acid acts as an emulsifier, helping mixtures like lotions and creams blend smoothly. It also provides thickness and stability to products. Additionally, stearic acid is used in the manufacturing of candles, soaps, and cosmetics, contributing to their texture and consistency.
