Ishizuka Glass Co. Ionpure

 

Why Inorganic?

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

Organic anti microbial agent 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, anti microbial agent, if inorganic, can be safe and gentle to the human body.

Ionpure by Ishizuka Glass Co. is a soluble glass containing anti microbial 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 anti microbial metal ions. With the presence of water or moisture, the glass will release the metal ions gradually to function as anti microbial agent.
