Description

Stearic Acid n-Dodecyl Ester is a high-purity, synthetic ester derived from stearic acid and lauryl alcohol. This compound serves as a versatile and effective non-ionic intermediate, offering excellent lubricity, hydrophobicity, and stability. It is primarily utilized in the formulation of high-performance lubricants, plasticizers, and personal care products across the chemical manufacturing, cosmetics, and polymer industries.

Application

• As a lubricant and mold release agent in plastic and rubber processing.
• As a plasticizer and softening agent for synthetic polymers and resins.
• As a waterproofing agent and emollient in cosmetic and personal care formulations (e.g., creams, lotions).
• As a intermediate and chemical building block for synthesizing more complex surfactants and esters.
• As a textile auxiliary for fiber lubrication and finishing.
• As a additive in coatings and inks to improve flow and surface properties.
