Hentriacontanoic acid

Hentriacontanoic acid (CAS 38232-01-8), also referenced in trade and research contexts as C31:0, is a long-chain saturated fatty acid used industrially as a lubricating and emulsifying agent. Its high carbon chain length positions it in specialty wax and fatty acid formulations where conventional shorter-chain acids fall short. In lubricants and metalworking fluids, it contributes to boundary lubrication performance.

This material is particularly effective in high-load or high-temperature processing conditions. Personal care formulators incorporate it into waxy emollient systems where its chain length supports film-forming. It is also utilized for texture modification in creams and solid cosmetic formats. In food-grade applications, it functions as a processing aid and emulsifier component in fat-based systems.

These applications often require controlled crystallization or surface coating. Research and analytical applications also draw on it as a reference standard for fatty acid profiling and lipid characterization. Hentriacontanoic acid is typically supplied as a white to off-white powder or solid. It is available primarily in research and specialty grades for various industrial and laboratory requirements.

Purity levels are commonly at 98% or higher for analytical and formulation use. Quantities range from small reference-grade lots to bulk technical supply depending on the specific application needs.
