What is Montanic acid?

Montanic acid (CAS 506-48-9) is a long-chain saturated fatty acid derived from montan wax. Also known as octacosanoic acid.

Where is Montanic acid used?

  • Plastics processing: internal and external lubricant reducing friction between polymer melts and metal surfaces during extrusion and injection molding
  • Personal care: structural integrity in stick formulations, emollients and wax-based products
  • Metalworking and industrial lubricants: base component in high-temperature greases and release agents
  • Coatings and masterbatch: plasticizer and dispersing agent for uniform pigment distribution
  • It improves flow and prevents sticking during high-speed production cycles.

Good to know: Buyers sourcing for cosmetic or personal care end uses should confirm grade compliance with relevant regional cosmetic ingredient standards. Store in a cool, dry environment to maintain chemical stability.
