Abstract
|
|
|
|
A colloid refers to dispersed particles of a solid or liquid having the diameter of about 10^(-5)- 10^(-7)cm. 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)
