The U.S. Environmental Protection Agency (EPA) has proposed registration of product to protect textiles.

The proposed registration decision is for a new nanosilver active ingredient, NSPW Nanosilver. The proposed pesticide product, POLYGUARD-NSPW MASTER BATCH (Polyguard), is for incorporation into textiles to suppress bacteria, algae, fungus, mold and mildew, which cause odors, discoloration, stains and deterioration.

The proposed pesticide product registration requires finished textiles to contain less than 0.003 percent silver by weight.

The public can submit comments to www​.regulations​.gov at Docket # EPA-HQ-OPP-2020–0043 on or before March 13th, 2020.
