Description

Arachidic acid (CAS 506-30-9 ), also known as eicosanoic acid, is a saturated C20 fatty acid derived primarily from peanut oil, fish oil, and other natural fats. It functions as a stabilizer, emulsifier, and surface-active agent across food, cosmetic, and industrial formulations. In personal care, this fatty acid is used to adjust the texture and consistency of creams, lotions, and lip products, contributing to a smooth, stable emulsion structure. Food manufacturers incorporate it as a stabilizer and antioxidant component in fat-based systems. In these systems, oxidative stability and shelf life are procurement priorities. In lubricant and metalworking formulations, it acts as a boundary lubricant and surface modifier, improving film adhesion on metal substrates for industrial processes. Surfactant producers also use it as a fatty acid feedstock for the synthesis of soaps, esters, and amide-based emulsifiers. This versatile chemical intermediate is essential for creating high-performance surfactants used in various cleaning and processing agents. Arachidic acid is supplied as a white to off-white powder or flake solid. It is available in technical grade for industrial applications and in higher-purity grades suitable for cosmetic and food-contact formulations to meet specific safety requirements. Standard specifications align with GC purity requirements, with typical commercial offerings ranging from 90% to 99%+ purity depending on end-use requirements.
