INCI Name: Stearic Acid
Stearic Acid 1801, a naturally occurring fatty acid found in plants, serves as a versatile ingredient in cosmetic formulations. Primarily functioning as a thickener and hardener, it aids in maintaining the shape of products like soap bars and candles, while preventing body butters from melting in warm conditions. Additionally, it exhibits potent cleansing properties as a surfactant.
Derived from natural plant sources, stearic acid 1801 plays a pivotal role in cosmetic formulations, offering a range of functions that contribute to the texture, stability, and performance of various products. This versatile fatty acid serves as a fundamental ingredient in skincare, haircare, and personal care formulations, where it delivers both structural support and cleansing efficacy.
One of the primary roles of stearic acid 1801 in cosmetics is its function as a thickener and hardener. When incorporated into formulations such as soap bars and candles, stearic acid helps to solidify the product, ensuring it maintains its shape and integrity during use. This makes it an essential component for creating stable and long-lasting products that retain their desired form under various conditions.
Stearic acid also serves as a valuable additive for enhancing the heat resistance and stability of cosmetic formulations, particularly in products like body butters and creams. By increasing the viscosity and consistency of these formulations, stearic acid helps prevent melting or softening when exposed to elevated temperatures, ensuring the product remains intact and usable even in warm environments.
Beyond its role as a thickener and hardener, stearic acid exhibits powerful cleansing properties, making it a key ingredient in surfactant formulations. As a surfactant, stearic acid effectively removes dirt, oil, and impurities from the skin and hair, helping to cleanse and purify without stripping away natural moisture. This dual functionality makes stearic acid a valuable component in a wide range of cleansing products, including facial cleansers, body washes, and shampoo bars.
