Tritriacontanoic acid

Tritriacontanoic acid (CAS 38232-03-0), also known as psyllic acid, is an ultra-long-chain saturated fatty acid derived from natural wax sources. It functions as a surface-active agent and lubricant additive across specialty industrial and personal care applications.

In personal care formulations, it contributes to the waxy, film-forming character of solid sticks, balms, and high-viscosity emollients where conventional fatty acids fall short. Lubricant and metalworking formulators incorporate it to modify surface adhesion.

This material is used to improve boundary lubrication performance in high-load conditions. Textile and leather processing operations use it as a fiber lubricant and surface treatment agent, reducing friction during mechanical processing and improving handle.

In paper manufacturing, it supports surface sizing and hydrophobic coating formulations where long-chain wax components are specified. This ensures the final product meets the necessary resistance and durability requirements for industrial use.

Tritriacontanoic acid is supplied as a white to off-white waxy solid, typically in powder or flake form. It is available primarily at technical grade, with purity levels commonly specified by GC assay to ensure consistent performance.

Packaging is standard for wax-type fatty acids, with bulk and smaller research quantities available depending on the supplier. This flexibility allows for both large-scale manufacturing and specialized laboratory research applications.
