Lithium stearate is a chemical compound composed of lithium and stearic acid, a long-chain fatty acid. It is a white, powdery or waxy substance that has several industrial and commercial applications. Here are some common uses and applications of lithium stearate.
Lubricating Greases
Lithium stearate is primarily used as a thickener and gelling agent in the manufacturing of lithium-based greases. These greases are widely used in automotive, industrial, and marine applications to lubricate various mechanical components, including bearings, gears, and chassis. Lithium-based greases are valued for their excellent mechanical stability and resistance to moisture.
Cosmetics and Personal Care Products
Lithium stearate can be found in cosmetic and personal care products, such as creams, lotions, and ointments. It is used as an emollient, thickening agent, and stabilizer to improve the texture and consistency of these products.
Pharmaceuticals
In the pharmaceutical industry, lithium stearate can be used as an excipient in the formulation of tablets and capsules. It aids in the binding of the active pharmaceutical ingredients, helping to form solid dosage forms.
Polymer Processing
Lithium stearate can serve as a processing aid and lubricant in the manufacturing of various plastic and polymer products. It helps improve the flow properties of the polymer melt during extrusion and molding processes.
Adhesives and Sealants
In the production of certain adhesives and sealants, lithium stearate can be used as a thickener, filler, or stabilizing agent to enhance product performance and consistency.
