lithium stearate is a white soft powder prepared by the reaction of lithium hydroxide and stearic acid. It is a component of lithium grease and is also used as a stabilizer in cosmetics and the plastic industry.

It is a general purpose thickener for natural and synthetic oils, which increases the melting point and enhances the elasticity of microcrystalline waxes. It is also a stabilizer for plastics and rubber products.

In addition, it is used in high temperature lubricating greases.

This substance is spontaneously combustible and emits toxic vapors of lithum when heated to decomposition.

It is used as a lubricant in industrial equipment, machinery, automobiles and in the chemistry industry.

lithium stearate is able to increase the melting point of base oils and enhance their elasticity. It has excellent anti-rust and corrosion properties and is resistant to loss of consistency and leakage.

This substance can be used as an emulsifier in aqueous solutions of polymerizations of elastomers and synthetic rubbers. It can also be used as a rust inhibitor in petroleum products.

It can be used in the manufacture of light weight metal moldings.

All substances in the lithium salts of monocarboxylic acids C14-C22 category are similar to each other and the properties are consistent throughout the range of carbon chain lengths covered by this group. The data for the longest and shortest carbon chain lengths were generated by testing of lithium myristate (C14) as a non-hydroxylated member, lithium 12-hydroxystearate (C18) as a hydroxylated member and lithium behenate (C22) as an hydroxylated member in GLP-compliant thermal analysis tests according to OECD guideline 102 (Harlan 2012, 2013).
