Inorganic Antibiotic Agent
 
A. Introduction
M-20 is nontoxic antibiotic agent which is composed of zeolite as carrier and metal ions which are harmless to the human body.  M-20 is an inorganic antibiotic agent which is manufactured by harmony of the antibiotic mechanism and our molecule design technologies.   Normally, 0.3 - 1.0 wt% of M-20 is added to the product which is endowed with antibiotic function, thus it shows most effective antibiotic ability through contact with various kinds of microbe.  Generally, organic antibiotic agents do not have high heat resistance.  In contrast, the inorganic agent, M-20 permits better thermal stability even at temperature up to 800`C or 800 centigrade, thus is displaying a wide range of applicability.
