MGK
®
Repellent
326
Summary
Uses
C
MGK
®
Repellent
326
is
used
for
application
to
companion
animals
(
i.
e.,
kittens,
cats,
puppies,
dogs,
and
horses)
and
their
outdoor
premises
(
i.
e.,
the
interior
of
kennels,
barns,
etc.),
and
direct
application
to
humans
to
repel
insects
only.

C
According
to
the
technical
registrant,
in
2002,
38%
of
the
total
amount
of
MGK
®
Repellent
326
was
sold
to
customers
with
pesticide
labels
for
use
as
"
personal
insect
repellents,"
54%
for
use
on
horses,
and
8%
for
use
on
dogs
and
cats.

C
MGK
®
Repellent
326
may
be
applied
topically
to
skin
and
clothes
on
an
as
needed
basis.
Products
used
as
insect
repellents
for
humans
contain
1%
to
4%
a.
i.
and
those
used
on
companion
animals
contain
1%
to
5%
a.
i.
However,
MGK
®
Repellent
326
is
never
used
alone
as
the
sole
active
ingredient;
it
is
mostly
used
to
enhance
the
repellency
of
other
formulation
components,
such
as
DEET
and
MGK
264.

Health
Effects
C
No
acute
hazard
endpoint
(
no
adverse
effects
were
associated
with
exposure
to
a
single
dose)
was
identified.

C
MGK
®
Repellent
326
is
currently
classified
as
a
probable
human
carcinogen
(
B2)
based
on
the
findings
in
the
rat
and
the
mouse
studies.

Risks
C
Acute
and
chronic
dietary
(
food
and
drinking
water)
risks
are
not
of
concern,
because
dietary
exposure
from
use
as
an
insect
repellent
is
not
expected.

C
Residential
non­
cancer
risks
from
dermal
and
incidental
oral
exposure
is
not
of
concern.

C
Residential
cancer
risks
are
of
potential
concern
from
dermal
exposure
to
MGK
®
Repellent
326;
however,
the
Agency
considers
this
assessment
to
be
conservative.

C
Aggregate
(
food,
water,
&
residential)
risks
are
not
of
concern,
because
there
is
no
potential
for
concurrent
exposure
via
the
food,
water,
and
residential
pathways.

C
Worker
risks
are
not
of
concern,
because
there
are
no
specific
occupational
uses
of
MGK
®
Repellent
326.

C
Ecological
risks
are
not
of
concern.
The
Agency
believes
that
there
is
little
to
no
exposure
to
non­
target
organisms
and
endangered
species
from
the
registered
uses.
