Description

Oleic acid (CAS 112-80-1 ) is a long-chain monounsaturated fatty acid derived primarily from animal and vegetable fats. It features FEMA 2815 recognition supporting its use as a flavoring agent in food applications. It functions industrially as an emulsifier, lubricant, surfactant, and surface modifier across a broad range of manufacturing sectors. In personal care and cosmetics, it acts as an emollient carrier and emulsification agent. This versatile fatty acid is used in creams, lotions, and soap formulations. Metalworking and industrial lubricant manufacturers incorporate it into cutting fluids and rust-inhibiting compounds to reduce friction. Its film-forming behavior is essential for protecting metal surfaces. Textile and leather processors use it as a softening and wetting agent to improve fiber flexibility and surface penetration of dyes and finishes. Food and flavor formulators rely on its FEMA-approved status to introduce fatty, oily notes in savory and dairy flavor profiles. The material is typically supplied as an amber to yellow liquid for industrial use. Food-grade and technical-grade are the most common commercial specifications. Food-grade material is manufactured to conform strictly to FCC standards for safety and consistency in production environments. Purity grades typically range from approximately 65% to 99% oleic acid content. High-purity refined grades are available for specialized cosmetic and food applications requiring the highest levels of quality and performance. Contact us for supply of Oleic acid Request Quote
