Montanic acid

Montanic acid (CAS 506-48-9) is a long-chain saturated fatty acid derived from montan wax, commercially recognized under the name octacosanoic acid. It functions as a wax-based processing aid and surface modifier across plastics, lubricant, and personal care manufacturing. In plastics processing, this acid acts as an internal and external lubricant, reducing friction between polymer melts and metal surfaces during extrusion and injection molding. This improves flow and prevents sticking during high-speed production cycles.

Personal care formulators incorporate it into stick formulations, emollients, and wax-based products where controlled hardness and emulsification are required. It provides structural integrity to cosmetic sticks while maintaining a smooth application profile. Metalworking and industrial lubricant manufacturers use it as a base component in high-temperature greases and release agents. Its high melting point wax character delivers exceptional film stability under heavy mechanical loads.

The material also functions as a plasticizer and dispersing agent in specialty coatings and masterbatch production. It ensures uniform pigment distribution and enhances the surface finish of the final coated or molded industrial products. This product is supplied as a white to off-white powder or flake solid. It is available in technical grade, with purity levels typically specified for industrial processing applications to ensure consistent performance in manufacturing.

Buyers sourcing for cosmetic or personal care end uses should confirm grade compliance with relevant regional cosmetic ingredient standards. Proper storage in a cool, dry environment is recommended to maintain the chemical stability of the fatty acid.
