Calcium Sulphonate Complex (CaS) greases do not function like other greases. In most greases the thickener releases the base oil to provide elastohydrodynamic lubrication in a bearing load zone. A Calcium Sulphonate (CaS) thickener is more like a gel. The base oil and gelled CaS thickener form a permanent emulsion. A well formulated CaS grease maintains the emulsified state, and the entire combination of thickener and base oil ‎pass through the bearing load zone. If the emulsion should break and the base oil bleed from the thickener, the CaS thickener left behind would still lubricate.
