Description

1-Octadecanol, also known as stearyl alcohol, is a long-chain fatty alcohol that serves as a fundamental building block in numerous industrial formulations. Its amphiphilic nature and waxy solid form make it an invaluable intermediate and functional additive. This high-purity compound is essential for manufacturers in the personal care, pharmaceutical, and chemical synthesis sectors seeking reliable consistency and performance.

Application

• Personal Care & Cosmetics: A key emollient, viscosity controller, and opacifying agent in creams, lotions, sticks, and hair care products.
• Pharmaceuticals: Used as an emulsifier, stiffening agent, and tablet coating component in ointments, creams, and controlled-release formulations.
• Chemical Synthesis: Acts as a crucial intermediate for producing surfactants, lubricants, plasticizers, and other stearyl derivatives.
• Textile & Fiber Industry: Employed as a softening agent, lubricant, and anti-static agent in fiber processing and finishing.
• Food Industry (as a release agent): Used in food-grade applications as a lubricant and release agent for baking and confectionery processes.
• Polishes & Waxes: Imparts hardness, gloss, and stability to industrial and automotive polishes and wax formulations.
