Description

9-Octadecanol is a high-purity, long-chain fatty alcohol, also known as stearyl alcohol. This compound serves as a versatile intermediate and functional additive, prized for its hydrophobic properties and ability to modify texture and stability. It is essential for manufacturers in the cosmetics, pharmaceuticals, and specialty chemical industries seeking reliable raw materials for formulations requiring emolliency, viscosity control, or as a precursor for ester synthesis.

Application

• As a key emollient and viscosity modifier in cosmetic and personal care products like creams, lotions, and ointments.
• As a co-emulsifier and stabilizer in pharmaceutical ointments and topical drug delivery systems.
• As a crucial chemical intermediate for the synthesis of surfactants, lubricants, and plasticizers.
• In the production of textile auxiliaries and fiber lubricants.
• As a component in industrial coatings and polishes to enhance gloss and water resistance.
• For use in food-grade applications as a release agent or defoamer, where compliant grades are available.
