Nonadecanoic acid

Nonadecanoic acid (CAS 646-30-0), also known as n-Nonadecylic acid, is a saturated C19 fatty acid used as a functional ingredient and reference standard across specialty chemical markets. It supports emulsification and lubrication in formulations where precise carbon chain length is commercially relevant. In analytical and food science laboratories, it serves as an internal standard for fatty acid profiling.

Its odd-chain structure distinguishes it from naturally abundant even-chain fatty acids during GC analysis. Lubricant formulators incorporate it into metalworking fluids and specialty greases to contribute boundary lubrication. This chemical helps improve surface protection under load in industrial settings. In personal care, it functions as an emulsifier and texture modifier in creams and ointments, contributing to emulsion stability.

It is also utilized for enhancing skin feel in various cosmetic applications. Food-grade applications include its use as a processing aid and lipid component in nutritional research formulations. Nonadecanoic acid is supplied as a white to off-white powder or flake solid. It is available in research-grade and technical-grade specifications to meet diverse industrial requirements.

High-purity grades of 98 to 99 percent are standard for analytical and reference standard applications. Packaging ranges from small quantities for laboratory use to bulk quantities for industrial procurement.
