Lithium Stearate

Lithium stearate is hydrophob, and swells in solvents. Moreover, because of its long fatty acid chains, lithium stearate leaves only minimal residue following heat treatment.   Additionally, lithium stearate is used as a thickener for natural and synthetic oils. It also raises the melting point and enhances the elasticity of microcrystalline waxes and paraffin. The dropping point of greases containing lithium stearate is much higher than those produced with aluminum stearates. Lithium stearate is also used in the manufacture of light weight metal moldings. Lithium stearates are available in powder form.
