Mechanical emulsion formulated siliconeemulsion
Typically, the silicone oil emulsionaccording to phase into an oil-in-water and water-in-oil two categories, theformer water as the continuous phase, silicone oil dispersed phase. The lattersilicone oil as the continuous phase, a dispersed phase of water. Silicone oilemulsion cosmetic except a small number of W / O type, the majority of the O /W type. Emulsion characteristics W / O type is a good cleaning effect.
Silicone emulsion stability of the emulsionis formulated using the emulsion of the most important requirements. Althoughsilicone oils may be formulated as almost semi-permanent emulsion. But in termsof thermodynamics, the emulsion is an unstable system. The long-term placementemulsion by temperature changes, or diluted by the high shear forces of oil andwater two-phase separation occurs, that is breaking. Breaking two processes:First, the dispersed droplets in the Van der Waals force action agglomerate,after the first flocculation coalescence.
