| Concerned that a spray intended
to deter bear attacks on humans may not be effective, the U.S. Environmental
Protection Agency today ordered the Missoula, Montana-based manufacturer
of “Bear Pause” to halt sales immediately.
EPA will also ask distributors to
pull the product from their shelves and advises people who bought the spray
not to rely on it. Bear Pause is made by ChemArmor of Missoula and carried
an EPA registration number (EPA Reg. No.71768-1).
At issue is the chemical formula
used in the spray. Capsaicin, the chemical that makes hot peppers hot,
is an EPA-approved active ingredient in pepper sprays used to deter attacks
by dogs and bears. While EPA had approved a purified form of capsaicin
in BearPause in March 1999, EPA learned that ChemArmor, without Agency
approval, had substituted a much cheaper and untested active ingredient
in Bear Pause, vanillyl pelargonamide, “VP” for short.
While belonging to the same chemical
family (capsaicinoids) and incorrectly called “synthetic capsaicin,” VP
is chemically distinct from capsaicin and is not used as the active ingredient
in any registered product in the U.S. EPA does not have reliable data on
its chemistry, toxicity, ecological effects or effectiveness.
“We don’t want people going into
bear country with a product on their hip that may not do its job if needed,”
said Tim Osag who enforces pesticide law for EPA’s Denver regional office.
“ChemArmor could apply to register
Bear Pause with VP,” Osag said, “but they would have to provide data about
its chemistry, its health and environmental effects, and its effectiveness.
They didn’t do that. In their original application, they stated that capsaicin
would be the active ingredient. We know capsaicin sprays are effective.
We can’t say that about VP.”
EPA is charged with oversight of
thousands of products in commerce. Makers of “pesticide” chemicals from
disinfectants to lawn chemicals to bear sprays must register their products
with the Agency. They provide information to EPA about contents, formulas,
uses and hazards. It is illegal to submit incorrect information in that
process. Osag said the Agency is considering additional enforcement and
registration options besides the “stop sales.”
“Right now, the most important thing
is to get the material off the market and get the word out to back-country
users,” Osag said.
EPA has not received evidence of
similar problems with other bear-deterrents on the market. As part of its
normal monitoring work, however, the Agency may test similar products in
the future to verify that they contain capsaicin and not VP, Osag said.

deterrents is attached to this news release and is also available on EPA’s
