Description

Dioctadecyl Malate is a high-molecular-weight diester derived from malic acid and stearyl alcohol. This compound is valued for its excellent lubricating properties and ability to act as a versatile non-ionic surfactant and emollient in demanding formulations. It serves as a critical performance additive in industries ranging from personal care to industrial lubricants and polymer processing. Global manufacturers rely on it for its consistency and ability to enhance product stability and texture.

Application

• Personal Care & Cosmetics: Used as a high-efficiency emollient, skin-conditioning agent, and viscosity modifier in creams, lotions, and makeup products.
• Industrial Lubricants & Greases: Functions as a friction modifier and anti-wear additive, improving lubricity and extending equipment life.
• Polymer & Plastic Additives: Acts as an internal and external lubricant and processing aid in PVC, polyolefins, and engineering plastics.
• Textile & Fiber Processing: Employed as a softening agent and spin finish component to reduce fiber breakage and improve handle.
• Coatings & Inks: Serves as a flow and leveling agent, enhancing gloss and surface smoothness in various coating systems.
• Adhesives & Sealants: Imparts plasticity and improves workability while maintaining adhesive strength.
