Description

Arachidyl Stearate is a high-purity, long-chain fatty acid ester derived from arachidyl alcohol and stearic acid. This compound serves as a highly effective emollient, lubricant, and viscosity modifier in premium formulations, offering excellent stability and skin-feel properties. It is a critical ingredient for manufacturers in the personal care, cosmetics, and specialty lubricants industries seeking superior performance and consistency.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emollient and thickener in creams, lotions, lipsticks, and makeup products, providing a non-greasy, smooth texture.
• Pharmaceutical Topicals: Used as an excipient in ointments, creams, and dermatological preparations for its skin-conditioning and stabilizing effects.
• Industrial Lubricants & Release Agents: Functions as a friction-reducing additive and mold release agent in plastics processing and metalworking.
• Textile & Fiber Processing: Employed as a softening agent and lubricant for synthetic fibers and yarns to improve processability.
• Food-Grade Lubricants & Coatings: Suitable for incidental food contact applications where a safe, stable lubricant or release coating is required.
• Candle & Wax Blends: Used to modify the melting point, hardness, and burn characteristics of specialty wax formulations.
