Pentacosanoic acid

Pentacosanoic acid (CAS 506-38-7), also known as hyenic acid, is a saturated C25 fatty acid used as a reference standard and functional ingredient in food, nutrition, and personal care formulations.

Its odd-chain fatty acid structure makes it a sought-after material for analytical calibration and biomarker research, as well as a functional component in emulsification and rheology systems.

In food and nutrition research, this acid serves as a certified reference standard for quantifying odd-chain fatty acids in plasma, dairy, and tissue samples. This is a growing area of interest in nutritional biomarker studies.

Personal care formulators incorporate it into emollient systems and wax blends where controlled melting behavior and film-forming consistency are required for high-end cosmetic products.

Its emulsifying properties support the stabilization of water-in-oil systems in topical creams and balms. In rheology modification, it contributes to the structural integrity of anhydrous formulations.

Common applications include lipsticks and solid serums where stability is paramount. The material is supplied as a white to off-white powder or crystalline solid for easy handling.

It is available in high-purity research and reference-grade specifications, typically at ≥98% or ≥99% purity. These grades are suited for both analytical and formulation use in various industries.

Packaging ranges from small quantities for laboratory applications to larger quantities for industrial-scale formulation work. We ensure the highest quality standards for all chemical shipments.
