Description

Decyl Stearate is a high-purity, long-chain fatty acid ester derived from stearic acid and decyl alcohol. This versatile compound serves as a premium emollient, lubricant, and viscosity modifier, prized for its excellent skin feel and stability. It is a critical ingredient for formulators in the personal care, cosmetics, and pharmaceutical industries seeking superior texture and performance. Its utility also extends to industrial applications as a plasticizer and processing aid.

Application

• Personal Care & Cosmetics: Acts as a primary emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup products for a non-greasy, silky feel.
• Pharmaceuticals: Used as an excipient in topical ointments, creams, and controlled-release formulations for its inert and stable properties.
• Plastic & Polymer Industry: Functions as an internal lubricant and mold release agent in PVC, polystyrene, and other polymer processing.
• Textile Manufacturing: Employed as a softening agent and lubricant for synthetic fibers and yarns to improve processability.
• Metalworking: Serves as a component in drawing compounds and cutting fluids, providing lubrication and corrosion protection.
• Industrial Coatings & Inks: Used as a flow modifier and gloss enhancer to improve the application and finish properties.
