What is Lithium stearate?

Lithium stearate (CAS 4485-12-5), also known as lithium soap, is a lithium-based metallic salt used as a thickener, lubricant, and stabilizer.

Where is Lithium stearate used?

  • Lubricants: primary thickening agent for lithium-based greases
  • Automotive and industrial bearings: greases with high-temperature stability and water resistance
  • Plastics: internal and external lubricant in PVC and other polymer systems, improving melt flow and preventing die buildup during extrusion
  • Personal care: emulsifier and texture modifier in stick formulations such as deodorants and lipsticks
  • Rubber and polymer compounding: stabilizer and release agent
  • It also acts as a stabilizer and release agent in rubber and polymer compounding.

Commercial specifications

  • Purity levels typically ranging from 98% to 99%+
  • Bulk supply in bags or fiber drums
