Treated carbonate fights microbes

Comments Email Print

U.S. Aragonite Enterprises LLC has launched a plastics performance enhancer that also imparts microbial control.

Oshenite MHP is based on naturally occurring Oshenite calcium carbonate treated with patented cationic carrier material called Fusionite from CMS Technology Inc. of Danbury, Conn. Fusionite forms a very stable microbial barrier in the Oshenite MHP material, according to CMS.

U.S. Aragonite of Salem, Mass., says Oshenite MHP disperses well, allowing the product to displace some plastic content and thus reduce reliance on fossil fuel-derived polymers. At the same time, the product inhibits bacteria that can cause foodborne illness, as well as odors, mildew and algae in packaging and consumer goods.

U.S. Aragonite’s Oshenite calcium carbonate has a very high surface area, making it well suited as a carrier for Fusionite, according to the company. Oshenite MHP is reportedly non-toxic and approved for direct food contact by the U.S. Food and Drug Administration.
