It is an aqueous solution of non-toxic surfactant used in sodium based surfactant muds. It provides easier control of rheology and filtration properties. It is a powerful detergent and surface active material of anionic-cationic type equally effective regardless of make up water, whether it is fresh, hard or saturated salt water.

It is an excellent emulsifier and may be used at any point in the drilling operation to improve emulsification and reduce torque and drag.
