Abstract
A gel-type pest repellent for use on the human body is provided which can decrease the inconvenience caused by the stickiness on the palm of the hand when applied. This aqueous gel-type pest repellent for use on the human body contains a gel base, a gelling agent, a pest repellent component, a UV degradation inhibiting component, and water. The pest repellent component is at least one item selected from the group consisting of 2-(2-hydroxyethyl)-1-piperidinecarboxylic acid 1-methyl propyl ester, 3-(N-n-butyl-N-acetyl)aminopropionic acid ethyl ester, and p-menthane-3,8-diol, and the UV degradation inhibiting component is ethylhexyl paramethoxycinnamate.
Description
[0001]
The present invention relates to a water-soluble gel-type
insect pest repellent for a human body.
[0002]
Conventionally, an aerosol type, which is easy to use,
has been the mainstream of insect pest repellents for human
bodies, but some users may experience irritation to the nasal
mucosa because insect pest repellent ingredients are atomized
into fine particles and sprayed on the skin surface. In
addition, the aerosol type insect pest repellent for a human
body may cause uneven application on its applied surface, forming
a part where an insect pest repellent ingredient does not adhere.
A biting pest such as a mosquitoe acutely senses this small part
and sucks blood therefrom. Thus, a gel-type insect pest
repellent is utilized because it does not cause uneven
application thereof and insect pest repellent ingredients are
less likely to be scattered.
[0003]
For example, a gel-like insect pest repellent composition for a human body that contains an insect pest repellent ingredient, a gel base agent, and water has been developed (see, for example, Patent Document 1). The gel-like insect pest repellent composition for a human body described in Patent
Document 1 has glycol as well as a brightening agent, blended as
a skin adhesion indicating agent of the insect pest repellent
ingredient.
[0004]
Patent Document 1: Japanese Unexamined Patent Application
Publication No. 2007-39342
[0005]
When applying a gel-type insect pest repellent for a human
body to a skin, it is necessary to take the contents of the
repellent onto the palm of the hand and then spread them on the
skin of an arm, a leg, or the like, or to discharge and apply
the contents of the repellent on a part of the skin of an arm,
a leg, or the like and then spread them over the entire surface
of the skin with the palm of the hand. Thus, when used, the
insect pest repellent for a human body adheres not only to the
arm, leg, or the like, but also to the palm of the hand. The gel-type insect pest repellent for a human body is also expected to be used outdoors where the hand cannot be washed immediately after its application, but some users may hesitate to apply the gel-type insect pest repellent for a human body because they feel that the palm of the hand becoming sticky is inconvenient during an outdoor activity. In this regard, the gel-type insect pest repellent composition for a human body of Patent Document
1 is directed to improve the visibility of the applied state of
the repellent by blending the skin adhesion indicating agent
therein, but it is not designed in consideration of the sticky
feeling on the palm of the hand along with its application.
[0006]
With the above problems in mind, the present invention
has been made. It is an object of the present invention to
provide a gel-type insect pest repellent for a human body that
can reduce the inconvenience caused by the sticky feeling on the
palm of the hand along with the application of the repellent.
[0007]
To achieve the above object, a gel-type insect pest
repellent for a human body according to the present invention is
characterized that
it is a water-soluble gel-type insect pest repellent for
a human body, including
a gel base agent, a gelling agent, an insect pest repellent ingredient, an ultraviolet degradation inhibiting ingredient, and water, wherein the insect pest repellent ingredient is at least one selected from the group consisting of 2-(2-hydroxyethyl)-1 piperidinecarboxylic acid 1-methylpropyl ester, 3-(N-n-butyl-N acetyl)aminopropionic acid ethyl ester, and p-menthane-3,8-diol, and wherein the ultraviolet degradation inhibiting ingredient is 2-ethylhexyl para-methoxycinnamate.
[0008]
In the gel-type insect pest repellent for a human body
having this feature, the used insect pest repellent ingredient
is at least one selected from the group consisting of 2-(2
hydroxyethyl)-1-piperidinecarboxylic acid 1-methylpropyl ester,
3-(N-n-butyl-N-acetyl)aminopropionic acid ethyl ester, and p
menthane-3,8-diol, which are excellent in the persistence of the
insect pest repellent effect, compared to DEET used as an insect
pest repellent ingredient in a conventional gel-type insect pest
repellent for a human body. Thus, such a gel-type insect pest
repellent can decrease the number of times of reapplication
thereof performed so as to maintain the insect pest repellent
effect and can be dried in a short time after its application,
thereby quickly resolving the sticky feeling. Further, since 2
ethylhexyl para-methoxycinnamate having a high ultraviolet
absorptivity is contained as the ultraviolet degradation
inhibiting ingredient, the insect pest repellent ingredient is prevented from being degraded due to the exposure to ultraviolet rays after its application even when used in summer with a large amount of ultraviolet rays, thereby making it possible to improve the persistence of the repellent effect and also to eliminate the necessity of frequent reapplication. As a result, the palm of the hand is maintained in the state with no sticky feeling for a long time, which can reduce the occurrence of inconvenience caused by the sticky feeling on the palm of the hand. Therefore, the user can use the gel-type insect pest repellent for a human body having this feature without hesitation.
[0009]
In the gel-type insect pest repellent for a human body
according to the present invention,
a content of the insect pest repellent ingredient is
preferably 3 to 20% by weight.
[0010]
In the gel-type insect pest repellent for a human body
having this feature, by containing the insect pest repellent
ingredient in the above-described content range, the insect pest
repellent is dried in a short time after its application while
being capable of adequately maintaining the insect pest
repellent effect, which can quickly resolve the sticky feeling
on the palm of the hand.
[0011]
In the gel-type insect pest repellent for a human body
according to the present invention, a content of the ultraviolet degradation inhibiting ingredient is preferably 0.1 to 1.0% by weight.
[0012]
In the gel-type insect pest repellent for a human body
having this feature, by containing the ultraviolet degradation
inhibiting ingredient in the above-described content range, the
viscosity of the ultraviolet degradation inhibiting ingredient
is alleviated, and the degradation of the insect pest repellent
ingredient due to ultraviolet rays can be sufficiently
suppressed without causing a sticky feeling when applied.
[0013]
In the gel-type insect pest repellent for a human body
according to the present invention,
the insect pest repellent preferably further contains a
dispersant of the ultraviolet degradation inhibiting ingredient.
[0014]
In the gel-type insect pest repellent for a human body
having this feature, by containing the dispersant of the
ultraviolet degradation inhibiting ingredient, the ultraviolet
degradation inhibiting ingredient can be dispersed in a uniform
state even when it is oil-soluble.
[0015]
In the gel-type insect pest repellent for a human body
according to the present invention,
the dispersant is preferably ethanol.
[0016]
In the gel-type insect pest repellent for a human body
having this feature, by using ethanol as the dispersant, the
cooling feeling is given to the user when the insect pest
repellent is applied, thereby making it possible to alleviate
the sticky feeling on the palm of the hand.
[0017]
In the gel-type insect pest repellent for a human body
according to the present invention,
the insect pest repellent preferably further contains a
moisturizer.
[0018]
In the gel-type insect pest repellent for a human body
having this feature, by containing the moisturizer, the insect
pest repellent for a human body is prevented from being
excessively dried after its application to thereby enhance the
adhesion of the insect pest repellent ingredient to the skin,
while giving the moist feeling to the skin when applied, so that
the sticky feeling on the palm of the skin can be alleviated.
[0019]
In the gel-type insect pest repellent for a human body
according to the present invention,
the moisturizer is preferably 1,3-butylene glycol and/or
a seaweed extract.
[0020]
In the gel-type insect pest repellent for a human body
having this feature, by using the above-described substance as the moisturizer, the adhesion of the insect pest repellent ingredient to the skin and the moist feeling when the insect pest repellent is applied become excellent.
[0021]
In the gel-type insect pest repellent for a human body
according to the present invention,
the gel-type insect pest repellent is preferably prepared
such that a drying time thereof measured in conformity with Part
3, Section 2 of JIS K 5600 is 10 minutes or less.
[0022]
In the gel-type insect pest repellent for a human body
having this configuration, by preparing the insect pest
repellent such that its drying time is 10 minutes or less, the
time required to dry the insect pest repellent for a human body
after its application to the skin can be sufficiently shortened,
thus quickly resolving the sticky feeling on the palm of the
hand.
[0023]
In the gel-type insect pest repellent for a human body
according to the present invention,
the gel-type insect pest repellent is preferably prepared
such that a turbidity thereof determined in conformity with a
visual method of 2.61 turbidity measurement in General Test
Method in the Japanese Pharmacopoeia 17th Edition is not more
than a turbidity of Reference suspension IV.
[0024]
In the gel-type insect pest repellent for a human body
having this configuration, the insect pest repellent does not
appear white and obtains a fresh look when applied to the skin
by preparing the insect pest repellent such that the turbidity
thereof determined in conformity with the visual method of the
turbidity measurement is not more than the turbidity of Reference
suspension IV.
[0025]

according to the present invention,
the gel-type insect pest repellent is preferably prepared
such that a viscosity thereof measured in conformity with JIS Z
8803 is 0.5 to 100 Pa-s.
[0026]
In the gel-type insect pest repellent for a human body
having this configuration, by preparing the insect pest
repellent such that its viscosity is 0.5 to 100 Pa-s, the insect
pest repellent can be easily applied and spread over the skin,
so that excellent adhesion and spreadability of the insect pest
repellent ingredient to the skin can be obtained.
[0027]
In the gel-type insect pest repellent for a human body
according to the present invention,
the gel-type insect pest repellent is preferably prepared
such that regarding a viscosity measured in conformity with JIS
Z 8803, a viscous damping ratio determined from an initial viscosity thereof and a final viscosity thereof measured after leaving the gel-type insect pest repellent outdoors for one week without shielding the light is 10% or less.
[0028]
In the gel-type insect pest repellent for a human body
having this configuration, by preparing the insect pest
repellent such that the viscous damping ratio is 10% or less,
its stable properties are maintained from the initial to final
stages of use, whereby the insect pest repellent can become a
product excellent in the usability.
[0029]
In the gel-type insect pest repellent for a human body
according to the present invention, the gel-type insect pest
repellent is preferably used to be applied to a head, a face, or

the insect pest repellent is suitable for use not only in the arm and leg of a human body, but also in the head, face, and neck which are particularly sensitive parts.
[0031]
Hereinafter, a gel-type insect pest repellent for a human
body of the present invention will be described below. Note
that the present invention is not intended to be limited to the
configurations described in embodiments below.
[0032]
[Insect Pest Repellent for Human Body]
The gel-type insect pest repellent for a human body of
the present invention is a water-soluble gel-type insect pest
repellent for a human body and contains a gel base agent, a
gelling agent, an insect pest repellent ingredient, and an
ultraviolet degradation inhibiting ingredient. The insect pest
repellent ingredient which is one of main ingredients of the
gel-type insect pest repellent for a human body of the present
invention is 2-(2-hydroxyethyl)-1-piperidinecarboxylic acid 1
methylpropyl ester [hereinafter referred to as icaridin], 3-(N
n-butyl-N-acetyl)aminopropionic acid ethyl ester [hereinafter
referred to as IR3535], or p-menthane-3,8-diol. Such insect
pest repellent ingredients may be used singly or in combination.
Icaridin, IR3535, and p-menthane-3,8-diol are excellent in
persistence of the insect pest repellent effect, compared to
DEET which is widely used as an insect pest repellent ingredient in a conventional gel-type insect pest repellent for a human body. Thus, the gel-type insect pest repellent for a human body of the present invention can decrease the number of times of reapplication thereof performed so as to maintain the insect pest repellent effect, compared to the conventional repellent with DEET blended in, and is dried in a short time after its application. The content of the insect pest repellent ingredient in the insect pest repellent for a human body of the present invention is preferably 3 to 20% by weight. By setting the content of the insect pest repellent ingredient in such a range, the time period required to dry the insect pest repellent after its application can be sufficiently shortened while being capable of adequately maintaining the insect pest repellent effect, so that the sticky feeling on the palm of the hand can be resolved quickly. When the content of the insect pest repellent ingredient is less than 3% by weight, the insect pest repellent ingredient that adheres to the skin is lost at an early stage through volatilization, resulting in a shortened time period during which the insect pest repellent effect is maintained. Consequently, the insect pest repellent for a human body needs to be reapplied frequently, causing the sticky feeling on the palm of the hand every reapplication. When the content of insect pest repellent ingredient exceeds 20% by weight, it may take a long time to dry the insect pest repellent after its application.
[0033]
Gel-type insect pest repellents for a human body are
expected to be used outdoors in summer when biting pests are
more likely to appear. The amount of ultraviolet rays is also
high in outdoor environment in summer. When the insect pest
repellent for a human body is prepared by increasing the content
of the insect pest repellent ingredient, assuming that the insect
pest repellent ingredient is degraded by ultraviolet rays during
use, it may take a longer time to dry the insect pest repellent
after its application. Increasing the content of the insect
pest repellent ingredient excessively is disadvantageous
economically. For this reason, the gel-type insect pest
repellent for a human body of the present invention contains an
ultraviolet degradation inhibiting ingredient which is blended
in order to suppress the degradation of the insect pest repellent
ingredient by exposure to ultraviolet rays after its
application. The ultraviolet degradation inhibiting ingredient
used in the present invention is 2-ethylhexyl para
methoxycinnamate. Because of its excellent absorption of
ultraviolet rays, 2-ethylhexyl para-methoxycinnamate can
suppress the degradation of the insect pest repellent ingredient
due to ultraviolet rays when blended into the insect pest
repellent for a human body, thereby improving the persistence of
the repellent effect. Therefore, it is not necessary to
excessively increase the content of the insect pest repellent
ingredient. Further, it is possible to decrease the number of
times of the reapplication of the insect pest repellent for a human body performed so as to maintain its insect pest repellent effect during use in summer. Moreover, it is also possible to prevent the sticky feeling on the palm of the hand from repeatedly occurring due to the frequent reapplication. 2
Ethylhexyl para-methoxycinnamate is a transparent liquid and
does not significantly impair the clarity of the insect pest
repellent for a human body when blended into the insect pest
repellent for a human body. As the ultraviolet degradation
inhibiting ingredient, organic compounds having an excellent
ultraviolet absorptivity can also be used. Examples of the
organic compounds include benzophenone derivatives, such as
oxybenzone, cinnamic acid derivatives, and the like. In addition
to the organic compounds, inorganic powders made of titanium
oxide, zinc oxide, cerium oxide, or the like, which are
ultraviolet scattering agents, may be blended as appropriate to
the extent that does not impair the clarity of the insect pest
repellent for a human body.
[0034]
The content of the ultraviolet degradation inhibiting
ingredient in the insect pest repellent for a human body of the
present invention is preferably 0.1 to 1.0% by weight. When the
content of the ultraviolet degradation inhibiting ingredient is
within such a range, the degradation of the insect pest repellent
ingredient due to ultraviolet rays is suppressed, so that the
persistence of the repellent effect can be maintained
sufficiently. Consequently, a balance between the persistence of the insect pest repellent effect and the dryness of the insect pest repellent becomes better. When the content of the ultraviolet degradation inhibiting ingredient is less than 0.1% by weight, the degradation of the insect pest repellent ingredient due to ultraviolet rays cannot be suppressed sufficiently, and the time period during which the insect pest repellent effect is maintained is shortened. Thus, the insect pest repellent for a human body needs to be reapplied frequently, causing the sticky feeling on the palm of the hand every reapplication. When the content of the ultraviolet degradation inhibiting ingredient exceeds 1.0% by weight, since 2-ethylhexyl para-methoxycinnamate which is the insect pest repellent ingredient is oil-soluble and viscous, the sticky feeling may be strengthened when applied. This means that the ultraviolet degradation inhibiting ingredient is blended in an amount that exceeds the amount of the ultraviolet degradation inhibiting effect required for practical use, which is economically disadvantageous.
[0035]
Examples of the gel base agent used in the present
invention include water-soluble polymers, such as carboxyvinyl
polymers, polyvinyl alcohol, and polyvinylpyrrolidone; acrylic
acid-based polymer compounds, such as acrylic acid copolymers,
acrylic acid-alkyl methacrylate copolymers, and alkyl acrylate
diacetone acrylamide copolymers; and polysaccharides, such as
alginic acid and salts thereof. In particular, a carboxyvinyl polymer is preferred. These gel base agents have thixotropy in aqueous solutions and exhibit sufficient thickening effect in small amounts. The content of the gel base agent is preferably
0.05 to 0.5% by weight. When the content of the gel base agent
is within such a range, the insect pest repellent for a human
body can be given sufficient viscosity, so that excellent
adhesion and spreadability of the insect pest repellent
ingredient over the skin can be obtained. When the content of
the gel base agent is less than 0.05% by weight, the viscosity
of the insect pest repellent for a human body becomes
insufficient and thereby the insect pest repellent may be
difficult to handle. When the content of the gel base agent
exceeds 0.5% by weight, its excessive viscosity may lead to
deterioration of the spreadability and skin penetration of the
insect pest repellent.
[0036]
The gelling agent is directed to increase the viscosity
of the gel base agent by adjusting pH. Examples of the gelling
agent used in the present invention include amines such as
triethanolamine and tetrahydroxypropyl ethylenediamine, sodium
hydroxide, aminomethyl propanol, and the like. In particular,
triethanolamine is preferred. The content of the gelling agent
in the insect pest repellent for a human body is adjusted
according to the content of the gel base agent, but is preferably
0.01 to 0.6% by weight. When the content of the gelling agent
is less than 0.01% by weight, the viscosity of the gel base agent may not be increased sufficiently. When the content of the gelling agent exceeds 0.6% by weight, the viscosity of the gel base agent is excessively increased, which may lead to deterioration of the spreadability and skin penetration of the insect pest repellent.
[0037]
In the present invention, in addition to the respective
ingredients mentioned above, a dispersant, a moisturizer, an
aromatic ingredient, and the like of the ultraviolet degradation
inhibiting ingredient may be blended as appropriate. Examples
of the dispersant of the ultraviolet degradation inhibiting
ingredient include alcohols such as ethanol and isopropanol. In
particular, ethanol is preferred. The content of the dispersant
is preferably 10 to 50% by weight. When the content of the
dispersant is within such a range, oil-soluble 2-ethylhexyl
para-methoxycinnamate can be uniformly dispersed in the insect
pest repellent for a human body while also giving the cooling
feeling to the user when applied. When the content of the
dispersant is less than 10% by weight, 2-ethylhexyl para
methoxycinnamate may not be sufficiently dispersed. When the
content of the dispersant exceeds 50% by weight, the irritation
on the skin may become stronger.
[0038]
Examples of the moisturizer include glycols such as 1,3
butylene glycol, propylene glycol, dipropylene glycol,
tripropylene glycol, diethylene glycol, triethylene glycol, hexylene glycol, and benzyl glycol; and seaweed extractss. In particular, 1,3-butylene glycol and seaweed extract(s) are preferred. The content of the moisturizer is preferably 0.1 to
10% by weight. When the content of the moisturizer is within
such a range, the insect pest repellent for a human body is
prevented from being excessively dried after its application, so
that a moist feeling can also be given to the user while
enhancing the adhesion of the insect pest repellent ingredient
onto the skin. When the content of the moisturizer is less than
0.1% by weight, the insect pest repellent for a human body may
be dried excessively after its application. When the content of
the moisturizer exceeds 10% by weight, it may take a long time
to dry the insect pest repellent after its application, and the
sticky feeling on the palm of the hand may not be resolved
quickly.
[0039]
Examples of the above aromatic ingredient include aromatic
ingredients such as orange oil, lemon oil, lavender oil,
peppermint oil, eucalyptus oil, citronella oil, lime oil, yuzu
oil, jasmine oil, hinoki oil, green tea essential oil, limonene,
a-pinene, linalool, geraniol, phenylethyl alcohol, amylcinnamic
aldehyde, cumin aldehyde, and benzyl acetate; and perfume
ingredients having leaf alcohol or leaf aldehyde blended
therein, called "fragrance of green".
[0040]
[Dryness]
The gel-type insect pest repellent for a human body of
the present invention is preferably prepared such that its
dryness, i.e., a drying time of a surface measured in conformity
with Part 3, Section 2 of JIS K 5600 (hereinafter simply referred
to as "drying time") is 10 minutes or less. When the drying
time is 10 minutes or less, the time required to dry the insect
pest repellent for a human body after its application to the
skin can be sufficiently shortened, thus quickly resolving the
sticky feeling on the palm of the hand. When the drying time
exceeds 10 minutes, it may take a long time to dry after its
application, and thus the sticky feeling on the palm of the hand
may not be resolved quickly.
[0041]
[Turbidity]
The gel-type insect pest repellent for a human body of
the present invention is preferably prepared such that
its turbidity determined in conformity with a visual method of
2.61 turbidity measurement in General Test Method in the Japanese
Pharmacopoeia 17th Edition is "not more than a turbidity of
Reference suspension IV" (30 NTU or less). When the turbidity
of the insect pest repellent is not more than the turbidity of
Reference suspension IV (30 NTU or less), the insect pest
repellent does not appear white and looks fresh when applied to
the skin. When the turbidity of the insect pest repellent
exceeds 30 NTU, it could appear white when applied to the skin.
[0042]
[Thixotropy (Viscosity)]
The gel-type insect pest repellent for a human body of
the present invention is preferably prepared such that its
viscosity measured in conformity with JIS Z 8803 (hereinafter
simply referred to as "viscosity") is 0.5 to 100 Pa-s. When the
viscosity of the insect pest repellent is within such a range,
the insect pest repellent can be easily applied and spread over
the skin, so that excellent adhesion and spreadability of the
insect pest repellent ingredient over the skin can be obtained.
In particular, the gel-type insect pest repellent for a human
body of the present invention has thixotropy and is preferably
prepared such that a measured value of the viscosity when used,
which is the time after applying the shear stress, is smaller
than a measured value of the viscosity when not used, which is
the time before applying the shear stress. If the measured value
of the viscosity of the insect pest repellent when used is
smaller than the measured value thereof when not used, the insect
pest repellent can be stably stored in a tube container because
of its relatively large viscosity when not used. Further, the
insect pest repellent can be easily applied and spread over the
skin because of its relatively small viscosity when used, and
thus the insect pest repellent ingredient obtains the excellent
adhesion and spreadability over the skin. This results in
excellent balance between good storage stability and ease of
application and spread when used.
[00431
[Applications of Insect Pest Repellent for Human Body]
The insect pest repellent for a human body of the present
invention is a gel type in which the insect pest repellent
ingredient is less likely to be scattered, wherein the contents
of the insect pest repellent ingredient and ultraviolet
degradation inhibiting ingredient are restrained within the
above-mentioned respective ranges. Thus, this insect pest
repellent for a human body can be used not only in the arm and
leg of the human body, but also in the head, face, and neck,
which are particularly sensitive parts. The gel-type insect
pest repellent for a human body of the present invention
demonstrates a high repellent effect against biting pests such
as mosquitoes, gnats, gadflies, ixodid ticks, stable flies,
house dust mites, bedbugs, biting midges, and land leeches, and
can be used to prevent any bite damage given by these pests.
[0044]
[Preparation Method]
The gel-type insect pest repellent for a human body of
the present invention is prepared by dispersing the gel base
agent in purified water, and adding and mixing, in this solution,
icaridin, IR3535, and/or p-menthane-3,8-diol which are the
insect pest repellent ingredients, as well as 2-ethylhexyl para
methoxycinnamate which is the ultraviolet degradation inhibiting
ingredient, followed by adding the gelling agent (pH adjuster)
thereto and then stirring this mixture. Even when a less water
soluble organic compound such as 2-ethylhexyl para methoxycinnamate is used as the ultraviolet degradation inhibiting ingredient, the gel-type pest repellant for a human body of the present invention can be easily prepared by adding and uniformly dissolving the dispersant such as ethanol and the moisturizer such as 1,3-butylene glycol in the solution containing the gel base agent dispersed in purified water, and then adding the insect pest repellent ingredient, the ultraviolet degradation inhibiting ingredient, and the gelling agent to the solution.
[0045]
Since the gel-type insect pest repellent for a human body
of the present invention obtained in this way contains icaridin,
IR3535, and/or p-menthane-3,8-diol as the pest repellant
ingredient, it is excellent in persistence of the insect pest
repellent effect, compared to DEET which is used as the insect
pest repellent ingredient in the conventional gel-type insect
pest repellent for a human body. Further, the insect pest
repellent of the present invention can quickly resolve the sticky
feeling on the palm of the hand with the insect pest repellent
spread thereover when applied. Furthermore, since the insect
pest repellent contains 2-ethylhexyl para-methoxycinnamate
having a high ultraviolet absorptivity as the ultraviolet
degradation inhibiting ingredient, the insect pest repellent
ingredient is prevented from being degraded due to the exposure
to ultraviolet rays after its application even when used in
summer with a large amount of ultraviolet rays. This makes it possible to improve the persistence of the repellent effect and also to eliminate the necessity of frequent reapplication. As a result, the palm of the hand is maintained in the state with no sticky feeling for a long time, which can reduce the occurrence of inconvenience caused by the sticky feeling on the palm of the hand. Thus, the user can use the gel-type insect pest repellent for a human body of the present invention without hesitation.

[0059]
Samples of the gel-type insect pest repellents for a human
body of Examples 1 to 7 and Comparative Examples 1 to 4 were
prepared. The properties of the respective samples of the gel
type insect pest repellents for a human body, specifically, (1)
viscous damping ratio, (2) active ingredient recovery ratio, (3)
drying time, and (4) turbidity were measured. Measurement
methods of the respective properties will be described below.
The measurement results of each sample are shown in Table 2.
[0060]
(1) Viscous Damping Ratio
A sample to be measured was poured into a glass container.
The viscosity of the sample in this state was measured, and a
measured value was defined as an initial viscosity (Al). Then,
after leaving this container outdoors for a week without
shielding the light, the viscosity of the sample was measured
again, and a measured value was defined as a final viscosity
(A2) . The viscosity of the sample was measured by the method in
conformity with JIS Z 8803. Then, the viscous damping ratio of
the sample was determined by the following formula (I).
Viscous Damping Ratio (%) = |A2 - All/Al x 100 - (I)
Assuming that the viscous damping ratio of the sample of
the gel-type insect pest repellent for a human body of Example
1 was 1, the relative ratio of the viscous damping ratio of each
sample in other Examples to the viscous damping ratio of the
sample in Example 1 was measured.
[0061]
(2) Active Ingredient Recovery Ratio
A sample to be measured was poured into a glass container.
The content of the insect pest repellent ingredient (active
ingredient) in the sample in this state was measured, and a
measured value was defined as an initial content (B1). Then,
after leaving this container outdoors for a week without
shielding the light, the content of the insect pest repellent
ingredient in the sample was measured again, and a measured value
was defined as a final content (B2). The content of the insect
pest repellent ingredient was measured by a gas chromatograph
(manufactured by Shimadzu Corporation, model: GC14B). Then, the
active ingredient recovery ratio of the sample was determined by
the following formula (II).
Active Ingredient Recovery Ratio (%) = B2/B1 x 100 ...
[0062]
(3) Drying Time
The drying time of the sample was measured by the
following procedure in conformity with Part 3, Section 2 of JIS
K 5600. First, two square glass plates (20 cm x 20 cm) were
prepared. A sample to be measured (0.1 g) was placed on one
glass plate and then applied and spread over its entire glass
surface (testing area), while the other glass plate was left
untreated (reference area). Then, ten foamed polystyrene pieces
(each 5 mm x 5 mm x 5 mm) were sprayed on the testing and reference areas of each of the glass plates, and subsequently the glass plates were set upright. Then, the number of the formed polystyrene pieces that fell was counted. This operation was performed every minute. The drying time was defined as the time period until the number of foamed polystyrene pieces that fell from the glass plate of the testing area was the same as that of the foamed polystyrene pieces that fell from the reference area.
[0063]
(4) Turbidity
The turbidity of the sample was measured according to the
procedure in conformity with the visual method of 2.61 turbidity
measurement in General Test Method in the Japanese Pharmacopoeia
17th Edition.

[0065]
As can be seen from Table 2, the gel-type insect pest
repellents for a human body of Examples 1 to 4, 6, and 7 were
excellent in usability because their viscous damping ratios were
reduced to 5% or less and their stable properties were maintained
from the initial to final stages of use. In addition, no
decrease in the amount of the active ingredients was observed,
and it was confirmed that the repellent effects of these insect
pest repellents were maintained over a long period of time.
Further, the drying time of each of these insect pest repellents
was 11 minutes or less, so that the sticky feeling was able to
be resolved quickly after its application to the skin. In a
gel-type insect pest repellent for a human body of Example 5,
the viscous damping was observed and a slight decrease in the
amount of the active ingredients was also observed, but the
drying time was 11 minutes, which was not problematic in terms
of practical use.
[0066]
In contrast, the gel-type insect pest repellent for a
human body of Comparative Example 1 had a very high viscous
damping ratio of about 90%, and could not maintain stable
properties. This is considered to be because the gel molecular
structure of the insect pest repellent for a human body was
degraded and destroyed by ultraviolet rays as it did not contain
2-ethylhexyl para-methoxycinnamate which was the ultraviolet
degradation inhibiting ingredient. The insect pest repellent of
Comparative Example 1 that did not contain 2-ethylhexyl para
methoxycinnamate resulted in a slight decrease in the amount of
the active ingredients, leading to a concern about the
persistence of the repellent effect. Further, this insect pest
repellent was difficult to use because its drying time was longer
than that of each of the insect pest repellents of Examples 1 to
7, and thereby the sticky feeling could not be resolved quickly
after its application to the skin.
[0067]
In a gel-type insect pest repellent for a human body of
Comparative Example 2 that contained DEET as the insect pest
repellent ingredient, the viscous damping ratio exceeded 10%,
making it difficult to maintain stable properties. Further,
this insect pest repellent was difficult to use because its
drying time required 13 minutes, and thereby the sticky feeling
could not be resolved quickly after its application to the skin.
[0068]
A gel-type insect pest repellent for a human body of
Comparative Example 3 contained 20% by weight of icaridin as the
insect pest repellent ingredient, but did not contain 2
ethylhexyl para-methoxycinnamate as the ultraviolet degradation
inhibiting ingredient. Thus, this insect pest repellent had a
very large value (about 80%) of the viscous damping ratio, like
Comparative Example 1 and thus could not maintain stable
properties. In addition, the amount of active ingredients was
decreased, which leads to a concern about the persistence of the repellent effect. Further, this insect pest repellent was difficult to use because its drying time required 14 minutes, and thereby the sticky feeling could not be resolved quickly after its application to the skin.
[0069]
Since a gel-type insect pest repellent for a human body
of Comparative Example 4 contained an excessive amount (of 30%
by weight) of icaridin as the insect pest repellent ingredient,
a significant decrease in the amount of active ingredients and
an increase in the drying time were observed. In addition, since
the insect pest repellent did not contain 2-ethylhexyl para
methoxycinnamate as the ultraviolet degradation inhibiting
ingredient, its viscous damping ratio became a very large value
(of about 80%), like Comparative Example 1, and thus could not
maintain stable properties.
[0070]
The gel-type insect pest repellent for a human body of
the present invention is usable for applications to prevent any
bite damage by biting pests, such as mosquitoes, gnats, gadflies,
ixodid ticks, stable flies, house dust mites, bedbugs, biting
midges, and land leeches.
