Ishizuka Glass Co. Ionpure


Why Inorganic?

Organic material has conventionally been the main stream of antimicrobial agents.
But recently, there have been many reports of illness caused by organic antimicrobial agents.

Organic antimicrobial agents can be easily transferred from the product to the skin through sweat. Also when vaporized, it is inhaled into the lungs, causing headaches and indisposition" (article from Mainichi Newspaper, June 9, 1998).

Generally speaking, inorganic materials are highly safe (non-volatile) and heat-resistant, compared to organic materials. Therefore, antimicrobial agents, if inorganic, can be safe and gentle to the human body.

Ionpure by Ishizuka Glass Co. is a soluble glass containing antimicrobial metal ions, and thus inorganic.

Comparison of Ionpure molecule to ordinary glass

Glass is generally considered as a material with high chemical inertness due to its strong network structure. However, it is possible to lower this chemical inertness by continuously altering its structure. In addition, glass has another interesting property; it retains metal as ions.

A combination of this property and the above technology has enabled Ishizuka Glass Co. the ability to create glass with low chemical inertness, which can also retain antimicrobial metal ions. With the presence of water or moisture, the glass will release the metal ions gradually to function as antimicrobial agents.
