Cetostearyl Alcohol

Generic structure of a fatty alcohol

Cetostearyl alcohol, also known as cetearyl alcohol, is a mixture of fatty alcohols, primarily consisting of cetyl alcohol and stearyl alcohol. It is commonly used in the cosmetic and pharmaceutical industries as an emulsifier, emollient, and thickening agent.

Chemical Composition

Cetostearyl alcohol is a white, waxy solid with a faint odor. It is composed of a blend of long-chain fatty alcohols, typically containing 30% cetyl alcohol (C16) and 70% stearyl alcohol (C18). These alcohols are derived from natural sources such as coconut oil and palm oil, or they can be synthesized from petrochemical sources.

Uses in Industry

Cosmetics

In the cosmetic industry, cetostearyl alcohol is widely used in the formulation of creams, lotions, and hair conditioners. It acts as an emulsifier, helping to stabilize and thicken products by preventing the separation of oil and water components. Additionally, it provides a smooth, velvety texture to the skin and hair, enhancing the sensory experience of the product.

Pharmaceuticals

In the pharmaceutical industry, cetostearyl alcohol is used as an excipient in the formulation of ointments and creams. It helps to improve the consistency and stability of these products, ensuring that the active ingredients are evenly distributed and effectively delivered to the skin.

Safety and Regulation

Cetostearyl alcohol is generally considered safe for use in cosmetic and pharmaceutical products. It is non-toxic and non-irritating to the skin, making it suitable for use in products designed for sensitive skin. Regulatory agencies such as the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have approved its use in various formulations.

Environmental Impact

The production of cetostearyl alcohol from natural sources such as coconut oil and palm oil raises concerns about sustainability and deforestation. Efforts are being made to source these raw materials from sustainable and certified suppliers to minimize environmental impact.
