For procurement managers and R&D scientists across various industries, a thorough understanding of chemical properties and applications is essential for making informed purchasing decisions. Octadecanamide, commonly known as Stearamide (CAS 124-26-5), is a versatile saturated fatty amide that plays a significant role in enhancing product performance and optimizing manufacturing processes. As a critical intermediate, knowing its characteristics can unlock new potential in your product development and production lines.

Key Chemical and Physical Properties:

Octadecanamide is a white to light yellow powder or granular solid. Its molecular formula is C18H37NO, and it has a molecular weight of 283.49 g/mol. A key characteristic is its melting point, typically ranging from 98-102 °C, which influences its behavior in various applications. While insoluble in water, it exhibits solubility in hot ethanol, chloroform, and ether, indicating its compatibility with a range of organic solvents and formulations. Its purity, often supplied at 98% or 99%, is a critical factor for its effectiveness in specialized applications.

Diverse Industrial Applications:

The utility of Octadecanamide stems from its multifaceted properties:

  • Lubricant and Release Agent: In the plastics industry, it serves as an excellent external lubricant and release agent for polymers such as PVC, polystyrene, and phenolic resins. This facilitates easier processing, prevents sticking to molds, and improves the surface finish of molded parts.
  • Slip and Anti-blocking Agent: For polyolefin films, Octadecanamide reduces the coefficient of friction, preventing layers from adhering to each other. This is vital for packaging films and other flexible plastic applications.
  • Cosmetic Ingredient: In personal care products, it acts as an emollient, moisturizer, and opacifier, improving skin feel and product texture in creams, lotions, and hair care formulations.
  • Rubber Processing Aid: It functions as a curing accelerator and processing aid in rubber manufacturing, enhancing dispersion and reducing processing times.
  • Corrosion Inhibitor: In industrial settings, particularly in oil wells, Octadecanamide forms a protective film on metal surfaces, inhibiting corrosion.
  • Sensitizer in Thermal Paper: Historically used as a sensitizer in thermal paper coatings, it contributes to the print quality.
