Nothing is added to artificially boost its strength of 20 parts-per-million. There are no patents, nor mysterious proprietary processes used. Domestic ingredients for better standards. Important Definition Colloidal silver ? is a solution that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution.1 The definitions of "colloid" and "ion" are not mutually exclusive. Colloidal silver can also be defined as “ionic” because an electric charge is holding the silver particles in suspension in the water; the liquid is both colloidal and ionic at the same time, by definition. Important Definition Ion ? an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons. Colloidal silver has a 100-year history of use as an anti-microbial, anti-pathogenic aid. It was widely used before modern antibiotics became prevalent. It has a clear to slightly yellow color and a mildly metallic taste.2 1Libretexts Chemistry Dictionary 2Webster's Dictionary
