The shelf life of this true colloidal Copper can be several years unopened. The average nanoparticle size is 2 Copper atoms with about 0.28 nanometers in size. There is no true colloidal Copper product with smaller Copper nanoparticles as we have inspected them all.

No (0.00%) chemicals are found in this product – only 99.99+% pure Copper nanoparticles colloidally suspended in pure distilled water. No other ingredients – especially no preservatives or stabilizers as found in other colloidal Copper products.


If allowed to freeze, all of the Copper nanoparticles will no longer be colloidally suspended and afterward the colloidal suspension may collapse resulting in a loss of color as the Copper nanoparticles will have fallen to the bottom of the bottle, leaving only clear water.

WARNING: Avoid contact with this product if allergic to Copper; allergic reactions to Copper are extremely rare.
