Description

Octadecanamide, n-(1-Methylethyl)- is a high-purity, synthetic amide derivative of stearic acid, also known as N-Isopropyloctadecanamide. This compound serves as a versatile intermediate and functional additive, valued for its hydrophobic and surface-modifying properties. It is primarily utilized in the formulation of industrial lubricants, polymer processing aids, and specialty chemical synthesis for sectors including plastics, coatings, and personal care.

Application

• As a slip agent and internal lubricant in polyolefin films and plastic processing to reduce friction and improve surface finish.
• Functioning as a waterproofing agent and hydrophobic modifier in coatings, textiles, and paper treatments.
• Acting as a key intermediate in organic synthesis for the production of more complex surfactants and amide-based chemicals.
• Use as a viscosity modifier and stabilizer in grease and industrial lubricant formulations.
• Potential application as a conditioning agent in hair care and cosmetic formulations for its emollient properties.
• Serving as a processing aid and mold release agent in the rubber and thermoplastic elastomer industries.
