4. Formation and Stabilization of Oil Foams by Crystalline Particles

An alternative to chemically modified solid particles is the use of surfactant crystals or fat crystals formed directly in the oil  . This is an innovative method that is increasingly being studied for stabilizing oil foams. This approach relies on the formation of crystals from lipophilic surfactants, such as fatty acids, fatty alcohols, mono- and diglycerides, or certain saturated triglycerides, sucrose esters, etc., which dissolve in the oil when heated and then crystallize...
