Stearyl alcohol is a fatty alcohol derived from natural sources, such as palm oil or coconut oil. It appears as a white, waxy solid and is commonly used in cosmetics and personal care products for its emollient properties, helping to soften and smooth the skin. In addition to its use in beauty products, stearyl alcohol acts as an emulsifier, helping to blend oil and water-based ingredients. It is also found in some food products and pharmaceuticals, where it serves as a stabilizer or thickening agent, contributing to the overall texture and consistency.
