ANIMAL REPELLENT COMPOSITION
FIELD OF THE INVENTION
The present invention relates to animal repellent compositions and to a method
of
repelling animals at a desired location.
BACKGROUND OF THE INVENTION
Compositions of matter used for repelling animals are well known in the art
and there
are various commercial compositions. The nature of the repellent composition
will vary
depending on the species of animal, bird or insect which it is intended to
repel. Most of the
repellents which have been utilized in the past are based on man made
chemicals specifically
targeted for certain species of animal. While these compositions are very
effective, they are
not considered ecologically desirable. Increasingly, regulatory authorities
are banning or
severely restricting the use of certain chemicals. These chemicals have been
found to enter
into the food and/or water supply and pose a health risk to humans.
The use of repellents containing naturally occurring ingredients is considered
to be
more environmentally friendly. Such repellents are shown, for example, in
United States
Patent 4,455,304 which teaches the use of a composition for repelling birds.
The
composition includes a finely divided garlic constituent and a finely divided
cayenne pepper
constituent.
United States Patent 4,795,637 teaches the use of a rodent repellent powder
which
uses thujone oil with a powder that can be selected from a number of different
products
including tobacco dust, pepper powder, sulfur powder, etc. The thujone oil is
derived from
the cedar tree and is a natural repellent.
United States patent 6,159,474 having common inventorship with the instant

application teaches an animal repellent which contains oils of black pepper
and/or capsicum.
The composition utilizes a carrier along with an essential oil, an oleoresin,
and an
antioxidant to stabilize the oleoresin and the essential oil. This composition
has been found
to be effective and can be utilized as a repellent for a number of different
larger species of
animals such as dogs, cats, racoons, skunks, mice, rats, squirrels, chipmunks,
deer, etc. The
composition utilizes only naturally occurring compounds for ecological
reasons.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved repellent
composition
which is effective against animals, utilizes naturally occurring ingredients
and which has a
minimum of toxicity.
It is a further object of the present invention to provide a method for
natural repelling
of domestic and other animals which have an olfactory capability.
According to one aspect of the present invention there is provided a liquid
animal
repellent composition comprising a liquid phase and an oil phase, the liquid
phase and the
oil phase being mixed together, the oil phase comprising an oleoresin of
capsicum in an
amount of between 2% and 6% by weight, an oleoresin of black pepper in an
amount of
between 2% and 6% by weight, an oleoresin of rosemary in an amount of between
0.1 % and
0.4% by weight, a non ionic surfactant in an amount of between 25% and 45% by
weight,
diacetyl tartaric acid esters of monoglycerides in an amount of between 25% to
45% by
weight, the liquid phase comprising between 10% and 20% by weight, the liquid
phase
comprising water, a preservative, a surfactant and a pH adjuster.
In greater detail, the repellent of the present invention is adapted to be
used for a
wide variety of animal species. It can be utilized for both domestic and wild
animals which

have olfactory capabilities. This would include dogs, cats, deers, skunks,
racoons,
groundhogs, gophers, etc.
The composition utilizes an oil phase in conjunction with a water phase. The
two
phases are then blended together to provide the final product.
In the oil phase, there is provided an oleoresin of both capsicum and black
pepper.
The active ingredient in the capsicum is capsacin, while the active ingredient
of the black
pepper oleoresin is piperine.
In addition to the oleoresins, there is also provided monodiglycerides along
with an
oleoresin of rosemary. Rosemary is an evergreen shrub of the mint family
labiatae and is
classified as genus rosemarinus species rosemarinus officinalis. The plant is
widely used as
a herb and is also used in perfumes. The oleoresin is desirable to provide a
longer lasting
effect to the repelling composition. Thus, it can function as an antioxidant
to stabilize the
other oleoresins. For example, the oleoresin of capsicum will normally oxidize
within
48 hours if it is not stabilized.
The percentage of the oleoresin of rosemary must be controlled since it must
be used
in an amount sufficient to perform its function as an antioxidant while too
large a quantity
will tend to neutralize the active repellent components. Preferably, the
oleoresin of
rosemary will be present in an amount of between 0.10 and 0.30 by weight.
The oleoresins of capsicum and black pepper are preferably present in
approximately
equal quantities and which may range from I% to 7% by weight of the
composition.
The three oleoresins are mixed and heated and monodiglycerides added thereto.
The
monodiglycerides are typically added in an amount of between 1% and 4% by
weight of the
final composition.

Subsequently, polysorbate 80K is added to the mixture and the mixture allowed
to
cool. The polysorbate preferably is present in an amount of between 25 to 40%
by weight of
the final composition.
Finally, for the oil phase, a bonsai extender which is a mixture of black
pepper oils
and diacetyl tartaric acid esters of monoglycerides are added. The bonzai
extender is
preferably added in an amount of between 2% and 6% by weight of the final
composition
while the diacetyl tartaric acid is present in an amount of between 25 to 45%
by weight of
the final composition.
The water phase will comprise biodegradable surfactants and enzymes along with
sodium benzoate and potassium sorbate. Citric acid may also be employed, all
of the above
ingredients being present in relatively minor amounts, each below 1% by
weight. They are
mixed with water which will be present in an amount of between 10 to 20% by
weight of the
final composition. Once the water phase is mixed, it is then blended with the
oil phase to
form the final composition.
Example 1
A composition was prepared according to the following formula:
Percentage
by weight
Oleoresin of capsicum 4.6
Oleoresin of black pepper 4.3
Mono-diglycerides 2.2
Oleoresin of rosemary 0.2
Polysorbate 80K 33.05
Bonzai extender 4.0
Diacetyl tartaric acid esters

Water 13.00
Citric acid 0.5
Biodegradable surfactants
and enzymes 0.5
Sodium benzoate 0.3
Potassium sorbate 0.3
Total: 100.00
The oleoresin of capsicum, oleoresin of black pepper, the mono-diglycerides
and the
oleoresin of rosemary were mixed well and heated until dissolved.
Subsequently, the polysorbate 80K was mixed in and the composition allowed to
cool. The bonzai extender, diacetyl tartaric acid esters of mono-glycerides
were
subsequently mixed into the composition.
In a separate container, the water, citric acid, biodegradable surfactants and
enzymes,
sodium benzoate and potassium sorbate were mixed.
The oil phase was then blended with the water phase.
The composition was applied by spraying to a field having problems with skunks
and
groundhogs and it was found to be effective for a period of approximately 30
days.
It will be understood that the above described embodiments are for purposes of
illustration only and that changes and modifications may be made thereto
without departing
from the spirit and scope of the invention.
