Plastics and Vinyl Producers Can Overcome OBPA Preservative Concerns with Lonza’s Vanquish and Omadine Family of Antimicrobials

March 13,2013

Atlanta, Georgia (USA), March 13, 2013 -- With the arsenic-based OBPA preservative no longer available in Europe due to a lack of manufacturer support, Lonza stands ready to supply a highly effective antimicrobial replacement to plastics and vinyl producers throughout the world. Lonza’s Vanquish™ and Omadine™ lines of antimicrobials, which are effective for control of fungi, bacteria and algae.

Registered for use by the U.S. Environmental Protection Agency and supported under the European Biocide Product Regulation (BPR) and in other global regions, Lonza’s Vanquish™ and Omadine™ Family of antimicrobials are used to protect plastic products made from polymers such as polyvinylchloride, polyurethane, silicones and others. These products will inhibit the growth of microorganisms that cause product deterioration, unsightly aesthetics, and unpleasant musty odors, These products are available as solids, liquids and dispersions.

"The elimination of OBPA in Europe and its uncertain future in the US are causing a great deal of confusion and concern among plastics and vinyl producers," says James Loricchio, Lonza’s Global Strategic Market Manager for Plastics. "Lonza can offer antimicrobial customers complete technical and supply chain support services resulting in a seamless transition to Lonza preservative products."

Mr. Loricchio reports that Lonza’s Vanquish™ 100, Vanquish™ SL 10 and Zinc Omadine™ family of antimicrobial products have already been in use for many years as an OBPA alternative by industry leaders in the flexible vinyl, polyurethane and other plastic markets. As of February 1, 2013, OBPA is no longer available in the European Union, and no supplier has decided to pursue its registration under the new Biocidal Products Regulation.

Lonza offers several OBPA alternative products and can tailor solutions for customers depending on the plastic being protected, application/end-use-environment and product-form preference.

In addition to vinyl floor coverings, carpet, rugs, underlay and mats, Lonza’s antimicrobial products have also been developed for use in many other end-use applications, including shower curtains, bathmats, coated fabrics, vinyl wall coverings, tarpaulins and awnings, roofing membranes, swimming pool and ornamental pond liners, conveyor belts and appliance gaskets.
