Bluing agents are the result of a simple chemical process. The main ingredient in bluing agent is a finely powdered iron that appears to be a very bright blue. This iron powder is colloquially referred to as Prussian blue, and formally called ferric hexacyanoferrate.
A reducing agent (also called a reductant or reducer) is an element or compound that loses (or donates) an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized. If any chemical is an electron donor (reducing agent), another must be an electron recipient (oxidizing agent). A reducing agent is oxidized because it loses electrons in the redox reaction.
