EPA Proposes Registration of Nanosilver Pesticide Product

For Release: August 27, 2013

On August 27, 2013, the EPA announced a proposed decision to register a nanosilver-containing antimicrobial pesticide product named “Nanosilva.” This silver-based product is used as a non-food-contact preservative to protect plastics and textiles (e.g., in household items, electronics, sports gear, hospital equipment, bathroom fixtures and accessories) from odor and stain causing bacteria, fungi, mold and mildew. The EPA evaluated the exposure to nanosilver from Nanosilva using data showing that plastics and textiles treated with the product released, at most, exceedingly small amounts of silver. The EPA reviewed other information on the product submitted by the applicant. We also used data from the scientific literature to evaluate the hazard of nanosilver. Based on this evaluation, the agency determined that Nanosilva will not cause unreasonable adverse effects on people, including children, or the environment. As a condition of registration, the EPA is requiring the company to generate additional data, for example, to confirm the agency’s understanding of the size of nanosilver particles in the product.

During the 30-day comment period after the announcement, anyone may submit comments, relevant data or information for the agency’s consideration. The Proposed Decision Memo is available at http://www.regulations.gov/#!docketDetail;D=EPA-HQ-OPP-2012-0594

Comments are due by September 26, 2013.
