What is Colloidal Silver
Many producers and promoters of Low PPM Colloids attempt to confuse the average buyer into believing their definition of what colloidal is, what a True Colloidal Silver is etc, etc.
From Wikipedia, the free encyclopedia
Milk is an emulsified colloid of liquid butterfat globules dispersed within a water-based solution.
"A colloid is a substance microscopically dispersed evenly throughout another substance. A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed. A colloidal system may be solid, liquid, or gas.
The dispersed-phase particles have a diameter of between approximately 1 and 1000 nanometers. Such particles are normally invisible in an optical microscope, though their presence can be confirmed with the use of an ultramicroscope or an electron microscope. Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols, colloidal emulsions, colloidal foams, colloidal dispersions, or hydrosols. The dispersed-phase particles or droplets are affected largely by the surface chemistry present in the colloid."
In a nut shell, a colloid can be anything that has something suspended in the solution.
