MORRISVILLE, US: Gelest Inc said that its Biosafe HM4100 antimicrobial is now approved for food contact and drinking water applications after FDA and EPA review.  

Biosafe is more cost effective than conventional silver-based antimicrobials while eliminating leaching concerns even at maximum prescribed levels.

Biosafe antimicrobial technology protects surfaces from staining, pitting, deterioration and odour caused by bacteria, mould, mildew and fungi. It does not compromise end-product safety by migrating out of the plastic or being rubbed off the surface.

Applications include commercial food prep surfaces, coatings, thin films, and laminates. Additionally, the EPA and FDA have reviewed the technology and found that Biosafe is compliant for use in polymeric beverage tubing and activated carbon water filter media.

Gelest’s amended EPA label for Biosafe HM4100 lists it as an approved use polymer and coating for food prep surfaces and polymeric beverage tubing at a loading level up to 1 percent by weight. However, the typical loading level of Biosafe additive required to effectively treat a given quantity of plastic or coating is between 0.2 and 0.5 percent. 

The keystone of Gelest’s Biosafe product line is HM4100 antimicrobial, which the company supplies as a solid powder. It contains no volatile organic compounds (VOCs), heavy metals, arsenic or polychlorinated phenols. Toxicity tests have shown them to cause no irritation or sensitization on skin contact.

With proper integration, Biosafe products exhibit high antimicrobial performance in ISO and ASTM testing. The active ingredient in the Biosafe antimicrobial was developed and registered with the US EPA in the mid-1970s and has since been widely used in numerous applications. Gelest has expanded the breadth of applications and manufacturing processes by removing VOCs and making the antimicrobial available in a new polymeric powder. The Biosafe powder can be compounded with polymer resins and used in food contact surface applications. 

“The enduring effectiveness of our Biosafe additive, combined with its compelling chemical and safety profile, makes this antimicrobial a powerful new tool for reducing unwanted microbes in food and drinking water applications,” said Donald Wagner II, technical marketing manager and inventor on the Biosafe patent.

“The global market for food contact materials has been in dire need of an alternative antimicrobial that is safe and effective. For years, customers have had to choose between silver or triclosan, both of which have come under tremendous scrutiny and in some cases have been banned outright for consumer products,” said Joel Zazyczny, executive vice president, Gelest.

“Biosafe HM4100 antimicrobial, when used as an additive or surface coating, offers value and differentiation in its longer-lasting ability to stay free and clean of microbial stains and odour, and it gives consumers peace-of-mind that their products are protected,” added Zazyczny.
