Effect of Homogenization Conditions on the Physicochemical Properties of Emulsion Bases

摘要: The effects of the first pressure and/or number passes through homogenizer, and preagitation by an agitator, on physical properties emulsion bases were investigated. homogenizer was varied in range 130 to 490kg/cm2, second kept constant at 60kg/cm2. Emulsifiers used commercial grade Tween 80 Span 20. Oil water phases liquid paraffin distilled water, respectively. Emulsion stability evaluated terms following three physicochemical parameters : (1) particle diameter, (2) separation rate phase, (3) rheological products. results obtained. With increases agitation time intensity agitation, diameter became smaller. viscosity prepared increased remarkably with increase homogenizer. greatly decreased only pass. (4) Pre-agitation agitator is very useful for preparation products means a
