Stearyl Alcohol is a long-chain fatty alcohol with the chemical formula C₁₈H₃₈O. It is widely used in pharmaceutical and laboratory applications as an emulsifier, thickening agent, and stabilizer.
🏭⚗️ Production
Stearyl alcohol is produced by hydrogenation of stearic acid obtained from natural fats and oils, such as palm or coconut oil. The purified product is a white, waxy solid suitable for pharmaceutical formulations and laboratory use.
🔬 Properties
Stearyl alcohol is a white, waxy solid with a mild fatty odor. It is insoluble in water but soluble in alcohol, ether, and chloroform. It has a melting point of 57–59°C and functions as an emulsifier, emollient, and stabilizer in various formulations. Chemically, it is stable and compatible with a wide range of excipients.
🧪 Applications
In pharmaceutical formulations, stearyl alcohol is used in creams, lotions, and ointments to stabilize emulsions, improve texture, and act as a thickening agent. In laboratory settings, it serves in lipid-based formulations, surfactant studies, and as a model excipient in formulation development. It is also used in cosmetic and personal care products.
⚠️ Safety
Stearyl alcohol is generally recognized as safe for pharmaceutical and laboratory use. It is non-toxic and non-irritant under standard handling conditions. The substance should be stored in a cool, dry place in tightly sealed containers to maintain quality and prevent contamination.
