Elaidic acid

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.

Where is Elaidic acid used?

• Industrial formulations: emulsifier, dispersant, lubricant base component
• Personal care and cosmetics: consistency and spreadability of creams, balms, stick formulations
• Metalworking and industrial lubricants: cutting fluids and boundary lubricants
• Its fatty acid structure provides film-forming and friction-reducing properties on metal surfaces.
• Food and nutrition research: reference standard or controlled ingredient for lipid systems
• Chemical intermediate in the synthesis of specialty esters and surfactants

Good to know: Its higher melting point relative to its cis counterpart determines processing behavior and end-product texture. High-purity grades are suitable for research, analytical reference use, and food-related formulation work.
