A STUDY ON THE STABILITY, EFFICACY, AND EFFECT OF COLLOIDAL SILVER EMULSION

A colloid refers to dispersed particles of a solid or liquid having the diameter of about $10^{-5}$ - $10^{-7}$. Such colloidal silver is produced by electrolysis. In this paper. colloidal silvers of various concentrations according to charge amount and time are produced, and their anti-microbial activities are measured. And optimum conditions for emulsion are measured by varying the concentration of colloidal silvers. Further, stability of the emulsion is measured with a Zeta potential. chrome meter by applying colloidal silvers to creams (W/Si. O/W, MLV).
