Elaidic acid
Description
Elaidic acid (CAS 112-79-8) is the principal trans isomer of oleic acid, produced commercially through partial hydrogenation or isomerization of unsaturated fatty acids. In industrial formulations, it functions as an emulsifier, dispersant, and lubricant base component.
Its higher melting point relative to its cis counterpart determines processing behavior and end-product texture. In personal care and cosmetics, it is used to adjust the consistency and spreadability of creams, balms, and stick formulations.
This material is ideal for applications where a firmer fatty acid profile is required. Metalworking and industrial lubricant manufacturers incorporate it into cutting fluids and boundary lubricants for enhanced performance.
Its fatty acid structure provides film-forming and friction-reducing properties on metal surfaces. Food and nutrition researchers and formulators source it as a reference standard or controlled ingredient for studying lipid systems.
It is frequently used for investigating the behavior of trans fatty acids in structured fat matrices. It also serves as a chemical intermediate in the synthesis of specialty esters and surfactants for various industrial applications.
The product is supplied as a white to off-white solid or waxy material, typically in flake or bulk solid form. It is available in technical grade for industrial and lubricant applications and high-purity grades.
These high-purity options are suitable for research, analytical reference use, and food-related formulation work. Our supply chain ensures consistent quality and availability for large-scale manufacturing and laboratory requirements.
