Description
FIELD OF THE INVENTION
[0001] This invention relates to a disposable glove treated with a
composition containing water, glycerol and a botanical extract and
the process for applying the composition onto the interior surfaces
of the glove.
BACKGROUND OF THE INVENTION
[0002] Disposable gloves are widely used as a protective measure to
insulate hands from microorganisms and irritants. Many workers,
especially those working in the health care, chemical and food
handling industries, rely on disposable gloves to provide a
protective barrier from harmful microorganisms and irritants.
Additionally, the increasing threat of exposure to bio-terrorism
has prompted many individuals to wear disposable gloves to protect
themselves against deadly microorganisms. Consequently, more
individuals are wearing disposable gloves for much longer periods
of time than in the past.
[0003] Disposable gloves are typically made from latex and vinyl
materials which tend to dry and irritate human skin. With the
increased use of disposable gloves comes a need to provide a
disposable glove that is comfortable to wear and will not dry and
irritate the hands of the wearer.
[0004] Many botanical extracts have been found to soften and soothe
dry and irritated skin. Aloe vera is a well known extract from the
aloe plant. Aloe vera is commonly used to treat burns because of
its healing, cooling, and moisturizing effects. Camomile is also a
well known herb commonly used in teas, but has been found to
exhibit anti-inflammatory properties when applied topically.
[0005] U.S. Pat. No. 6,274,154 is directed to a disposable glove
containing a film of dehydrated aloe vera on the interior surface
of the glove. This patent describes applying a solution of aloe
vera to the interior surface of a glove, then heating the glove
until the water is dehydrated, leaving a film of dehydrated aloe
vera on the interior surface of the glove. Since the water is
completely dehydrated, the interior surfaces of the glove do not
contain any significant amount of moisture. Since no moisture is
present, the dehydrated aloe vera peels off as powder thereby
minimizing any moisturizing effect.
[0006] The present invention fills a present need of providing a
glove that is non-irritating to the skin and moisturizes the skin
as it is worn.
BRIEF SUMMARY OF THE INVENTION
[0007] The present invention is directed to a glove wherein the
interior surfaces of the glove contain a film which includes water,
glycerol and a botanical extract, the water present in an amount
ranging from about 30 mg to about 90 mg per glove.
[0008] Another embodiment of the invention is directed to a method
of applying a film to the interior surfaces of a glove which
includes washing a cured glove, drying the washed glove in a
tumbler dryer at a temperature of about 50 to about 55.degree. C.,
spraying a solution into the tumbler dryer while the washed glove
is drying and is partially wet, and drying the washed glove until a
film forms on the interior surfaces of the washed glove.
[0009] A further embodiment of the invention is directed to a
composition containing water, glycerol, camomile, a thickener, an
anti-blocking wax, a wetting agent, a fragrance, a silicone
emulsion and a preservative.
BRIEF DESCRIPTION OF THE DRAWINGS

[0011] FIG. 2 shows spraying the moisturizing mixture into the
tumble dryer while the gloves are drying.
[0012] FIG. 3 illustrates the continued spraying of the
moisturizing mixture and tumbling of the gloves in the tumble
dryer.
[0013] FIG. 4 shows the drying process for the gloves.
DETAILED DESCRIPTION OF THE INVENTION
[0014] The present invention provides a glove which has a film on
the interior surfaces of the glove. The film is formed by spraying
an untreated glove with a composition containing water, glycerol,
and a botanical extract while drying in a tumbler dryer. As the
glove is tumbled in a tumbler dyer, the tumbling mechanism allows
the composition to creep inside the glove when the glove is
partially wet. The water from the surface of the glove acts as a
carrier for the composition, enabling the composition to form a
film throughout the interior surfaces of the glove. The glove is
further dried in the tumbler dryer, however, the resulting interior
surfaces are moist to the touch. The embodiments of the instant
invention are directed to the treated glove, the composition that
is sprayed onto the glove, and the process of forming the film onto
the interior surfaces of the glove.
[0015] An untreated glove, i.e. a glove that has not been treated
with the composition of the present invention, is made from natural
rubber latex, polyvinyl chloride, polychloroprene rubber,
polyisoprene rubber, butyl rubber, acrylonitrile butadiene rubber
(NBR), carboxylated nitrile, polyurethane rubber, polyacrylate,
latices of styrene-butadiene rubber and blends of natural rubber
latex with synthetic latices.
[0016] A preferred untreated glove is a single layer glove
manufactured by dipping a heated former into Powder-Free Coagulant
(PFC), which is then partially dried in an oven, followed by a
single latex dip. A single latex layer is formed on the glove
former.
[0017] It has been discovered that the composition of the present
invention containing the combination of water, glycerol and a
botanical extract has hygroscopic properties when applied to the
surface of a disposable glove. The hygroscopic nature of the
composition is responsible for the treated glove surface retaining
moisture when the composition is sprayed on an untreated glove
while drying in a tumbler dryer. The amount of moisture retained on
the treated surfaces of the glove is between 30 and 90 mg/glove,
preferably about 60 mg per glove.
[0018] Water is present in the composition of the present invention
in an amount ranging from about 75 to about 98 weight percent,
preferably from about 85 to about 95 weight percent, based on the
total weight of the composition.
[0019] Glycerol is a humectant that is commonly used in cosmetics,
liquid soaps, and confectioneries for its moisturizing properties.
Many botanical extracts are soluble in glycerol; however, glycerol
must be present in the composition of the present invention in an
amount sufficient to bind the botanical extract onto the interior
glove surface and attach to the human skin while wearing the glove.
The effective amount of glycerol in the composition ranges from
about 1 to about 14 weight percent, preferably from about 1 to
about 7 weight percent, based on the total weight of the
composition. Relative to a rubber glove weight of 7 to 10 g, the
glycerol is present at a range of about 5 to 30 mg inside and 10 to
40 mg outside.
[0020] Suitable botanical extracts present in the composition of
the present invention may include, but are not limited to,
camomile, aloe vera, jojoba, aloe barfadenis extract, passion
flower extract, cucumber extract, comfrey leaf extract, saponaria,
officinalis extract, myrrh extract, eucalyptus extract, seaweed
extracts, and combinations thereof.
[0021] A preferred botanical extract is camomile. Another preferred
botanical extract is aloe vera. A more preferred embodiment is a
combination of camomile and aloe vera. The botanical extract is
present in an amount of from about 0.01 to about 2.0 weight
percent, preferably from about 0.05 to about 0.5 weight percent,
based on the total weight of the composition.
[0022] The composition of the present invention may also contain
thickeners, anti-blocking polypropylene waxes, wetting agents,
fragrances, preservatives, and combinations thereof. The function
of a coating thickener is to increase the viscosity of the
moisturizer mixture, thereby allowing moisturizers to remain evenly
on the glove surface during the tumbling and drying process.
[0023] Thickeners include, but are not limited to carboxymethyl
cellulose and polysaccharide (xanthan) gum, hydroxyethyl cellulose,
polyacrylate, polyvinyl alcohol, and combinations thereof. A
preferred thickener is carboxymethyl cellulose. Another preferred
thickener is xanthan gum. The thickener is present in an amount
from about 0.05 to about 0.6 weight percent, preferably from about
0.1 to about 0.3 weight percent, based on the total weight of the
composition.
[0024] An anti-blocking wax is present to prevent any blocking
phenomenon due to the hygroscopic properties of the composition of
the present invention. Anti-blocking waxes include, but are not
limited to, paraffin wax, microcrystalline wax, polypropylene wax,
and combinations thereof. A preferred anti-blocking wax is
polypropylene wax. The anti-blocking polypropylene wax is present
in an amount ranging from about 1.0 to about 8.0 weight percent,
preferably from about 2 to about 5 weight percent, based on the
total weight of the composition.
[0025] Wetting agents include, but are not limited to, fatty
alcohol ethoxylate, othyl phenol ethoxylate, nonyl phenol
ethoxylate, sodium alkyl sulphate, sulphated methyl oleate, and
combinations thereof. A preferred wetting agent is fatty alcohol
ethoxylate or nonyl phenol ethoxylate. The wetting agent is present
in an amount ranging from about 0.1 to about 1.0 weight percent,
preferably from about 0.3 to about 0.9 weight percent, based on the
total weight of the composition.
[0026] Preservatives include, but are not limited to, citric acid,
sodium benzoate, potassium sorbate, methyl paraben, sodium sulphite
and sodium metabisulphite, and combinations thereof.
[0027] Preferred preservatives are citric acid and sodium benzoate.
Preservatives are present in an amount ranging from about 0.01 to
about 0.5 weight percent, preferably from about 0.05 to about 0.2
weight percent, based on the total weight of the composition.
[0028] Fragrances include, but are not limited to, vanilla, lilac,
jasmine, rose, lemon floral, strawberry, gardenia, apple spice,
banana, pumpkin spice, carnation, honey kiwi, tangerine, mandarin,
peppermint, mango, violet, ylang-ylang, cassis, bergamot,
grapefruit, rosemary, combinations of the above mentioned
fragrances and a complete range of Nivea fragrances.
[0029] A preferred fragrance is Nivea scent. Fragrances are present
in an amount ranging from about 0.5 to about 10 weight percent,
preferably from about 2 to about 8 weight percent, based on the
total weight of the composition.
[0030] Another embodiment of the invention is directed to a method
of applying a film containing the moisturizing composition of the
present invention to the interior surfaces of a glove. A cured
glove ex-machine is first washed in a tumble washer for a total of
two cycles according to the following parameters:
[0031] Off-line Washing
1 Gloves Time per Medium Volume (Qty) cycle Temperature Fresh 1200
liters per tumble 14,000 pcs 34.5 minutes Ambient clean washing.
Two washing per cycle water per cycle.
[0032] After washing the cured gloves, the wet gloves are partially
dried in an AMBI.TM./Challenger dryer (available from Texchine
Incorporated, USA) or a COSMOS dryer (available from COSMOS
Engineering, Malaysia) at a temperature ranging from about 40 to
about 70.degree. C., preferably from about 48.degree. to about
55.degree. C. for about 10 to about 50 minutes. While the gloves
are partially wet and still drying, an aqueous solution of the
moisturizing composition of the present invention is sprayed into
the dryer. The amount of moisturizing solution sprayed into the
dryer varies from 18 liters to 36 liters per sample of gloves,
depending on the moisturizing effect needed for end users. A sample
of gloves contains about 14,000 pieces. For optimum moisturizing
effect, the preferred amount of moisturizing solution is 36
liters.
[0033] A silicone emulsion may also be sprayed into the dryer along
with the moisturizing solution. This allows the glove's outer
surface to be siliconised. Silicone is used to ensure that the
gloves do not block and the glove's outer surface does not become
tacky. A preferred silicone emulsion is Silicone LE 45. Silicone
emulsion is present in an amount ranging from about 0.5 to about
4.0 weight percent, preferably from about 1.0 to about 2.0 weight
percent, based on the total weight of the moisturizing
composition.
[0034] The gloves are further dried at a temperature of about
48.degree. to about 52.degree. C. for another 3 to 5 hours. The
amount of moisturizing composition retained on the surfaces of the
glove ranges from about 0.1 to 2.0 mg/glove, preferably from about
0.5 to about 1.5 mg/glove. The size of the gloves ranges from about
size 6 to about size 8.
[0035] The tumbling mechanism allows the moisturizing composition
to coat the glove and creep inside the glove during the initial
stage of drying when the gloves are still partially wet. The water
on the gloves acts both as a carrier and lubricating medium.
Further drying after the spraying of the moisturizing composition
causes some, but not all of the water to evaporate, leaving a moist
coating formulation on the treated glove surface.
[0036] The following examples further illustrate the invention but,
of course, should not be construed as in any way limiting its
scope.
COMPARATIVE EXAMPLE 1
[0037] The moisture content of standard PFC gloves (available from
Ansell (Kedah) Sdn Bhd, Kulim Industrial Estate, Kulim, Kedah,
Malaysia) was measured according to the following method. Each
sample contained ten pieces of size 8 gloves. The ten pieces of
gloves were weighed, oven dried at 100.degree. C. for 30 minutes,
and weighed after drying. The moisture content was calculated based
on the weight of the water lost during drying, calculated by
subtracting the weight of the sample after drying from the weight
of the sample before drying. The percentage of water lost from
drying was calculated as a percentage by the following equation: 1
Weight of sample before drying - Weight of sample after drying
Weight of sample before drying .times. 100 %
[0038] The results are shown in Table 1. All weights are expressed
as grams.

[0039] As shown by this comparative example, the weight of the
gloves after drying was less than the weight of the gloves before
drying, showing that untreated standard PFC gloves contain small
amounts of moisture.
EXAMPLE 2
[0040] The moisture content of gloves containing a full strength
mixture of the moisturizing composition of the present invention
was measured by the following method. A moisturizing composition
was prepared by mixing the ingredients listed in Table 2 below.

[0042] Ex-machine cured gloves (14,000 pieces of size 7 gloves)
were washed in a tumble washer for a total of two cycles according
to the following parameters:
[0043] Off-Line Washing
4 Gloves Time per Medium Volume (Qty) cycle Temperature Fresh 1200
liters per tumble 14,000 pcs 34.5 minutes Ambient clean washing.
Two washing per cycle water per cycle.
[0044] The washed gloves were then dried in an AMBI.TM. dryer at a
temperature ranging from about 50.degree. to about 55.degree. C. at
ambient pressure. A full strength mixture of the above moisturizing
composition (a volume of 18 liters) was sprayed into the dryer
after one sample of gloves (about 14,000 pieces of size 7 gloves)
was dried for about 25 minutes. The gloves were further dried for
about 3 hours.
[0045] The treated gloves were then weighed, oven dried at
100.degree. C. for 30 minutes, and weighed after drying. As in
Comparative Example 1, each sample contained ten gloves. The
moisture content was calculated by the same method in Comparative
Example 1. The results are shown in Table 3 below. Weights are
expressed in grams.

[0046] Table 3 shows that gloves containing a full strength
composition contain significantly greater amounts of moisture (as
shown by the percent water loss) than standard PFC gloves
(Comparative Example 1.).
EXAMPLE 3
[0047] Example 2 was repeated, but with only a 50% moisturizing
composition. The volume of mixture was the same (i.e. 18 liters)
but the moisturizing composition of Example 2 was diluted 50/50
with water.
[0048] The results are illustrated in Table 4. Weights are
expressed in grams.

[0049] Table 4 shows that, even when only a 50% moisturizing
solution is sprayed onto the gloves, the amount of moisture on the
treated gloves is twice as much as the standard PFC untreated glove
(Comparative Example 1.).
EXAMPLE 4
[0050] This example demonstrates the coverage of the composition of
the present invention as a film on the interior surface of the
glove and the percentage of moisturizers remaining on the glove
after the drying process. For measurement purposes, soda ash
(sodium carbonate) was introduced into the 36 liters (Trial 1) and
18 liters (Trial 2) of moisturizing solution at a concentration of
200 grams per liter of moisturizing solution. The moisturizing
solution with the soda ash was then sprayed into the dryer
containing a sample of gloves (14,000 pieces of size 7 gloves)
during the drying process.
[0051] Two sets of test samples, each consisting of four pieces of
wet gloves, were taken from the dryer after 15 minutes of tumbling.
Another two sets of test samples, each consisting of four pieces of
dried gloves, were taken from the dryer after the drying process
was completed. One set of samples was tested on extraction for the
whole glove surface and another set was tested on extraction for
inner surface only. Each glove was extracted with 100 ml of
de-ionized water. Results are expressed as the average value of
four pieces of gloves.
[0052] The quantity of soda ash on the glove was determined by the
following titration. A glove was tied and placed in an extraction
bottle containing 100 ml of de-ionized water. The extraction bottle
was fixed to an overhead mixer and agitated for about 30 minutes.
The extraction was charged into a 250 ml conical flask. Three drops
of phenolphthalein were added to the extract. 0.1 M of HCL was
added until the pink color disappeared. This is the end point. The
results are shown in Table 5.

[0053] The results show that out of the total moisturizer mixture
applied into the tumbler dryer, about one third of the moisturizer
mixture remained on the gloves after the complete drying process.
The coverage of moisturizer mixture inside the glove is about the
same as outside surface i.e., 50% on each side. The results also
show that the moisturizer mixture was able to reach up to the
inner/inside fingertip area.
EXAMPLE 5
[0054] The moisturizing effect was determined using the following
hand touch assessment method. A total of eight subjects tested
gloves from different sub-lots made with 50% strength moisturizing
solution and full strength moisturizing solution. Both hands of a
subject were washed, rinsed with cold water, and dried. The hands
were further air dried by waving the hands in the air for 30
seconds. The treated gloves were then placed on the hand and warmed
for 10 minutes. The subject was then asked to rate the moisturizing
effect and scent of the gloves, using the following numbers:
