Description

1,2,3-Propanetriyl Tris(12-Hydroxyoctadecanoate) is a high-purity, synthetic triester derived from 12-hydroxystearic acid and glycerol. This compound serves as a versatile and effective non-reactive plasticizer, lubricant, and viscosity modifier in a wide range of industrial formulations. It is particularly valued in the production of high-performance polymers, specialty greases, and cosmetic products where stability and compatibility are critical. Global industries rely on this material for its consistent quality and ability to enhance product performance under demanding conditions.

Application

• Polymer & Plastic Additive: Acts as an internal lubricant and plasticizer in PVC, polyurethane, and other engineering plastics to improve flexibility and processing.
• Grease & Lubricant Formulation: Used as a thickening agent and base oil component in high-temperature, multi-purpose lithium complex and calcium sulfonate greases.
• Cosmetics & Personal Care: Functions as an emollient, viscosity controller, and stabilizer in creams, lotions, lipsticks, and makeup products.
• Coatings & Inks: Serves as a flow modifier and leveling agent to improve the application properties and finish of industrial coatings and printing inks.
• Adhesives & Sealants: Imparts flexibility and reduces viscosity in hot-melt and pressure-sensitive adhesive systems.
• Textile & Fiber Processing: Employed as a softening agent and lubricant for synthetic fibers and yarns during manufacturing.
• Metalworking Fluids: Used as a component in synthetic and semi-synthetic cutting and drawing fluids for its lubricity and stability.
• Pharmaceutical Excipient: Can be utilized as a non-toxic carrier and release modifier in topical drug delivery systems.
