Description

Bis[(Z)-9-Octadecenoic Acid]2,2-Dimethyl-1-(1-Methylethyl)-1,3-Propanediyl Ester is a specialized diester derivative of oleic acid, valued for its role as a high-performance emollient, lubricant, and chemical intermediate. Its molecular structure, featuring a branched neopentyl glycol core, provides excellent oxidative stability and low-temperature properties, making it a superior alternative to linear esters. This compound is essential for formulators in the personal care, cosmetics, and specialty lubricants industries seeking advanced, non-greasy ingredients with enhanced skin feel and compatibility.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup products, providing a smooth, non-greasy feel and improved spreadability.
• Lubricants & Greases: Serves as a synthetic base oil or additive in specialty lubricants, metalworking fluids, and release agents, offering excellent thermal stability and low pour points.
• Polymer & Plastic Additives: Used as a plasticizer and internal lubricant in PVC, engineering plastics, and elastomers to enhance flexibility and processing characteristics.
• Textile & Leather Processing: Functions as a softening agent and lubricant in fiber treatments and leather finishing to improve suppleness and durability.
• Industrial Coatings & Inks: Employed as a flow modifier and viscosity regulator in solvent-based and high-solid coatings, printing inks, and adhesives.
• Chemical Synthesis: Utilized as a versatile building block or intermediate for producing more complex esters, surfactants, and specialty chemicals.
