Understanding the foundational science behind chemical ingredients is crucial for effective formulation and application. 1-Octadecanol, commonly known as Stearyl Alcohol (CAS 112-92-5), is a saturated fatty alcohol with a molecular formula of C18H38O. Its structure, a long C18 hydrocarbon chain capped with a hydroxyl group, dictates its unique and valuable properties. As a leading manufacturer and supplier, we provide insights into this essential chemical, from its production to its widespread applications.

The physical properties of 1-Octadecanol are key to its functionality. It typically appears as a white, waxy solid, often in the form of flakes or granules. It has a melting point generally between 56-59 °C and is insoluble in water but soluble in organic solvents like alcohol, acetone, and ether. This insolubility in water, combined with its waxy nature, makes it an excellent choice for applications requiring water resistance or a barrier effect, such as in certain cosmetic and pharmaceutical formulations.

Production of 1-Octadecanol commonly involves the catalytic hydrogenation of stearic acid, a process that adds hydrogen to the molecule. Alternatively, it can be derived from natural fats and oils through esterification and subsequent reduction. These methods ensure a high purity product, essential for its use in demanding industries. For companies looking to buy 1-octadecanol, understanding the production method can be informative about its suitability for specific applications.

The applications of 1-Octadecanol are remarkably diverse. In the cosmetic and personal care industry, it excels as an emollient, softening and smoothing the skin, and as a thickener, enhancing product texture and viscosity. Its emulsifying properties are critical for stabilizing oil-in-water and water-in-oil emulsions found in creams, lotions, and hair conditioners. Beyond cosmetics, it finds utility in pharmaceuticals as an excipient in ointments and controlled-release systems, and in industrial sectors as a lubricant additive.
