Acetal-Compatible Antimicrobial Solution Fights Infection

With the intent of reducing the chances for risky and costly hospital-acquired infections, Microban International (Huntersville, NC) has developed an antimicrobial technology that is compatible with acetal. The company reports a better than 4-log reduction of a range of organisms using its standard, enhanced, and human-serum-based testing protocols.

Identified by the Centers for Medicaid and Medicare Services (CMS) as devices of concern, catheters are especially prone to biofilm formation, which can lead to infection. And while progress appears to have been made through the integration of various antimicrobial additives and polymers used in many catheter applications, acetal-based catheter tubing has not been able to reap the benefits. Processing issues with various additives is a common drawback to acetal, according to Microban; chemical degradation and formaldehyde off-gassing in the end product can occur. 

The antimicrobial solution produced by Microban, however, is compatible with acetal. Furthermore, it does not cause destabilization or formaldehyde generation, according to the company.

"This new work is a significant step forward and will help medical device manufacturers to offer an antimicrobial solution that is more robust and provides more consistent antimicrobial performance," says Ivan Ong, vice president of R&D for Microban.
