Cetostearyl Alcohol is a mixture of fatty alcohols, primarily cetyl alcohol (C16H34O) and stearyl alcohol (C18H38O). It appears as a white, waxy solid at room temperature and is widely used in pharmaceutical and laboratory formulations for its emulsifying, thickening, and stabilizing properties.
🏭⚗️ Production
Cetostearyl Alcohol is produced through the reduction of fatty acids derived from natural sources such as coconut oil and palm kernel oil. The resulting mixture contains primarily stearyl and cetyl alcohols in proportions that ensure consistency and suitability for pharmaceutical and laboratory applications.
🔬 Properties
Cetostearyl Alcohol is insoluble in water but soluble in ethanol and ether. It has a melting point around 50°C and a boiling point near 249°C. The substance is non-toxic, non-irritating, and chemically stable, functioning as a safe emulsifier and thickening agent for topical formulations and laboratory preparations.
🧪 Applications
In pharmaceutical formulations, Cetostearyl Alcohol is used as an emulsifier and stabilizer in creams, ointments, and lotions, ensuring uniform dispersion of active ingredients and enhancing product stability. It also acts as a thickening agent to improve the texture and consistency of topical preparations. In laboratory settings, it is used in the preparation of emulsions and as a component in the formulation of controlled-release drug delivery systems.
⚠️ Safety
Cetostearyl Alcohol is generally recognized as safe for topical use. Rare allergic reactions may occur in sensitive individuals. Standard handling procedures, including proper storage and hygiene, should be followed to ensure safety during pharmaceutical or laboratory use.
