Shelf life of colloidal silver

In principle, colloidal silver cannot go bad because germs cannot survive in silver water.

The botanist Robert Brown discovered during observations with a microscope that, for example, the grains of pollen in a drop of water are constantly moving.This Brownian motion of visible tiny bodies can be explained using the particle model: the tiny body is repeatedly pushed by the invisible particles that are in constant motion.In colloidal silver, the silver particles are electrically charged and constantly repel each other, thus remaining suspended.

The particle charge slowly decreases over time. With longer storage, partial deposits of silver can occur on the vessel walls, which of course then leads to a loss of concentration. It is therefore obvious to use dispersions that are as fresh as possible. Provided that storage is optimal.
