Partial List of Ionic Silver Products

The list of products below are sold as "colloidal silver" but a more technically correct description for these products would be "ionic silver solutions" because they typically contain 90% ionic silver and only 10% silver particles. Not all products in the table have been tested. A dash (-) indicates that the product has not been tested.

Effectiveness of a colloid is determined by the particle surface area making it the single most important metric for comparing colloids.
