Where can I find a list of EPA-approved inks for Water Soluble Packaging (WSP)?
There is no specific list of approved inks for water soluble packaging (WSP). For a listing of inert ingredients permitted for use in nonfood use pesticide products refer to the Agency web site http://www.epa.gov/opprd001/inerts/inert_nonfooduse.pdf. For a listing of inert ingredients permitted for use in food use pesticide products refer to the tolerance exemptions listed in 40 CFR 180 beginning with 40 CFR 180.910 (available at http://www.access.gpo.gov/nara/cfr/waisidx_07/40cfr180_07.html).
