Description

Octadecyl Palmitate is a high-purity, long-chain fatty acid ester synthesized from stearyl alcohol and palmitic acid. This compound serves as a versatile and effective emollient, lubricant, and viscosity modifier in advanced formulations. It is essential for manufacturers in the personal care, cosmetics, and specialty chemical industries seeking to enhance product texture, stability, and performance. Its excellent skin feel and compatibility with a wide range of ingredients make it a valuable component for premium-grade products.

Application

• Personal Care & Cosmetics: Acts as a primary emollient and skin-conditioning agent in creams, lotions, lipsticks, and sunscreens, providing a smooth, non-greasy feel.
• Hair Care Products: Used as a conditioning agent and gloss enhancer in shampoos, conditioners, and hair styling products to improve manageability and shine.
• Pharmaceutical Topicals: Serves as a base or excipient in ointments, creams, and topical drug delivery systems due to its excellent spreading properties and skin compatibility.
• Industrial Lubricants & Release Agents: Functions as a bio-based lubricant, mold release agent, and processing aid in plastics, rubber, and metalworking applications.
• Textile & Leather Processing: Employed as a softening and waterproofing agent for fabrics and leather goods.
• Specialty Waxes & Polishes: A key ingredient in the formulation of high-quality car polishes, furniture waxes, and candle additives to modify hardness and melting point.
