Description

Oleyl Alcohol CAS NO 143-28-2 is a monounsaturated fatty alcohol derived from natural sources, prized for its excellent emollient properties and chemical versatility. Its unique structure provides a crucial balance of lipophilicity and a reactive hydroxyl group, making it a foundational intermediate and functional ingredient. This product is essential for manufacturers in the cosmetics, pharmaceuticals, and industrial lubricants sectors seeking high-purity, consistent raw materials.

Application

• Cosmetics & Personal Care: A key emollient and viscosity modifier in creams, lotions, hair conditioners, and lipsticks, providing a smooth, non-greasy feel.
• Pharmaceuticals: Used as a solubilizer, penetration enhancer, and carrier in topical ointments, transdermal patches, and suppository bases.
• Industrial Lubricants & Metalworking: Serves as a friction-reducing additive and corrosion inhibitor in synthetic lubricants, rolling oils, and cutting fluids.
• Textile & Leather Processing: Acts as a softener, lubricant, and anti-static agent in fiber processing and leather finishing.
• Chemical Synthesis: A vital intermediate for producing surfactants, plasticizers, and other oleyl-based derivatives like oleylamine.
• Printing Inks & Coatings: Functions as a flow control agent and pigment dispersant to improve application properties and finish.
