Description

1-Octadecanol, also known as stearyl alcohol, is a long-chain fatty alcohol with the CAS number 112-92-5. This versatile compound serves as a crucial intermediate and functional additive, prized for its emollient, thickening, and surfactant properties. It is an essential raw material for manufacturers in the personal care, cosmetics, pharmaceutical, and chemical synthesis industries.

Application

• Cosmetics & Personal Care: A key emollient and viscosity builder in creams, lotions, ointments, and hair conditioners.
• Pharmaceuticals: Used as an emulsifying agent, stiffening agent, and tablet coating component.
• Chemical Synthesis: Acts as a precursor for the production of plasticizers, lubricants, and surfactants like stearyl sulfates and ethoxylates.
• Textile & Leather Processing: Functions as a softening agent, lubricant, and anti-static agent in fiber and leather treatment.
• Food Industry (as a release agent): Employed in food-grade applications as a lubricant and release agent for baking pans and confectionery molds.
• Industrial Applications: Serves as a defoamer, lubricant additive, and intermediate for specialty chemicals.
