Fatty alcohols are long-chain alcohols derived from natural fats and oils. They typically contain 12 to 22 carbon atoms and are used in various industries, including cosmetics, detergents, and lubricants. Common examples include lauryl alcohol and stearyl alcohol, which are known for their emollient properties. These alcohols are often produced through the hydrogenation of fatty acids or by the reduction of fatty esters. Fatty alcohols serve as surfactants, helping to stabilize emulsions and improve the texture of products. They are considered safe for use in personal care items and are biodegradable, making them environmentally friendly.
