Examination of a Theoretical Model for Drainage of Foams Prepared from Licorice Root Extract Solution

The root of the licorice plant (Glycyrrhiza glabra) is rich in natural surfactants, called saponins. beneficial properties this have led to different applications, including its use as a foaming agent. In research, theoretical model and validity are discussed for liquid drainage foams made from extract solutions. After stating important characteristics free foam, relationship drained volume based on effective parameters was obtained via simplification governing equation. applied experimental foam data measured at concentrations A comparison results shows good agreement function time. combination allows quantification rate. addition, rate beginning decay process, measure stability, can be estimated using measurable properties.
