Complex Soap

Glossary Term

Definition and Purpose

Complex soap is a soap thickener that is created by the co-crystallization of two or more compounds, typically involving a primary soap and complexing agents such as metal salts of organic or inorganic acids. These agents modify the characteristics of the grease, often enhancing properties like the dropping point, which is the temperature at which the grease becomes fluid. The presence of complex soap in lubricating greases is crucial for applications requiring high-temperature stability and performance.
