Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a composition for hand disinfection, which can be preferably used when a medical worker in a medical institution or the like disinfects a finger, and a hand disinfection method using the same, and is particularly excellent in disinfection effect. The present invention relates to a composition for hand disinfection which is highly durable and is effective in preventing infection of patients in hospitals and protection from infection of medical staff and the like, and a hand disinfection method using the same.

[0002]

BACKGROUND ART Conventionally, basin method (immersion method), swab method (wiping method), scrub method (cleaning method), rubbing method (rubbing method) have been used for disinfecting fingers of medical staff in hospitals and the like.
Four types of disinfection methods have been adopted. inside that,
The basin method is a method of disinfecting by immersing your fingers in an antiseptic solution placed in a washbasin, and the swab method is immersing the disinfectant in a cotton ball or gauze and then wiping the skin surface to disinfect it. Is the way to do it. Further, the scrubbing method is a method in which the skin surface is thoroughly scrubbed with a disinfectant containing a cleaning agent and water, and a brush or the like is also used to disinfect while foaming. Thus, each of these three types of disinfection methods has its own problems. That is, the basin method has the problem of contamination of the disinfectant itself and the contamination of fingers when drying with a towel, and the swab method has a problem that it cannot be sufficiently disinfected in a short time. As with the Basin method, there is an inherent problem of finger contamination during towel drying.

Therefore, in recent years, such as ethanol for disinfection,
A rubbing method, which uses an antiseptic solution prepared by adding a low-concentration disinfectant to a quick-drying alcohol solvent, picks it up, and rubs it strongly to dry the fingers at the same time as disinfection, is often used. It became so. This is also called quick dry disinfection method, but this disinfection method
Since a new disinfectant solution is always used every time disinfection, there is no problem of contamination of the disinfectant solution itself, and since it is not necessary to use a towel etc., there is no possibility of cross-contamination, and it is simple and easy.
It is attracting attention as a method that allows easy disinfection of fingers. Further, in this method, even after the quick-drying alcohol solvent is evaporated and the finger surface is dried, a disinfectant such as chlorhexidine gluconate or benzalkonium chloride contained in the disinfectant is applied to the skin of the finger. As it is adsorbed and remains,
There is also the new advantage that the disinfectant effect will continue to some extent.

However, the bactericide remaining on the skin of the fingers is physically lost due to contact with something or the like, or is inactivated by the organic matter secreted from the skin surface. The duration of the disinfecting effect of the dry rubbing disinfectant is usually as short as 30 minutes to at most 2 hours. For this reason, for example, when the rubbing method is used for disinfecting the fingers of a medical staff or the like during surgery, the disinfectant effect of the bactericide often disappears during the operation. In addition, at the time of surgery, medical workers wear surgical gloves after disinfecting their hands, but these gloves tend to have pinholes during the operation, and therefore after the duration of the disinfecting effect has passed. This poses a risk of infection for both patients and healthcare professionals.

Further, in JP-A-4-134036, an iodine preparation containing 0.01 to 0.2% of effective iodine and 50% by weight of alcohol for disinfection are used as the disinfectant used in the above-mentioned quick-drying rubbing disinfection method. % And 1% by weight or less of a chemically and formulationally stable antiseptic drug composition for hands and fingers have been clarified. However, this hand and hand sanitizer is very effective in sustaining the disinfection effect. It wasn't something.

[0006]

The present invention has been made in view of such circumstances, and the problem to be solved by the present invention is that it is preferably used in a quick-drying rubbing disinfection method. It is an object of the present invention to provide a composition for hand sterilization that can maintain the effect for a long time and an effective method for hand sterilization using the same.

[0007]

SOLUTION: In order to solve the above problems,
In the present invention, a hydrophilic polymer which is insoluble in water and soluble in an alcohol solvent as a solvent to be used and which has a film-forming ability, a bactericide, and an alcohol solvent in a proportion of more than 50% by weight. A gist of the present invention is a composition for hand disinfection, which comprises:

According to the first preferred embodiment of the composition for hand disinfection according to the present invention, as the hydrophilic polymer, a homopolymer or copolymer of 2-hydroxyethyl methacrylate, or a saponification degree of 10 is used. ~ 50 mol% polyvinyl alcohol will be advantageously used.

According to a second preferred embodiment of the composition for hand disinfection according to the present invention, the hydrophilic polymer is
It is present in a concentration of 0.2-5% by weight.

Furthermore, according to the third preferred embodiment of the composition for hand disinfection according to the present invention, povidone iodine is used as the bactericide.

Furthermore, according to a fourth preferred embodiment of the composition for hand disinfection according to the present invention, as the bactericide,
A bactericide containing 2,4,4'-trichloro-2'-hydroxydiphenyl ether will be used.

In the present invention, a finger is treated with the above-mentioned composition for hand sterilization as described above, so that the surface of the finger is coated with the hydrophilic polymer containing a bactericide. A method for disinfecting hands and fingers, which is characterized in that the disinfectant is formed, is also the gist of the invention, whereby a polymer film for ensuring the sustainability of the disinfecting effect is advantageously formed.

[0013]

[Operation / Effect] In short, in the composition for hand disinfection according to the present invention, a specific hydrophilic polymer having the ability to form a water-insoluble film is dissolved in an alcohol solvent to form a solution. Since the predetermined bactericide is dissolved or dispersed, various problems in the conventional disinfectant composition can be solved completely.

That is, in such a composition for hand disinfection,
When disinfecting the fingers, a water-insoluble polymer film is formed on the surface of the fingers after the alcoholic solvent is evaporated and the disinfectant is contained in the disinfectant. The bactericidal effect) is obtained.

More specifically, since the composition for hand disinfection according to the present invention uses an alcohol-based solvent such as ethanol for disinfection as a solvent, the composition for hand disinfection can be prepared by a quick-drying rubbing disinfection method or a spray method. When such a composition for hand and finger disinfection is applied to fingers, first, the strong bactericidal effect of the alcoholic solvent is exhibited. Then, when the alcoholic solvent evaporates, the hydrophilic polymer in the hand sanitizing composition has a film-forming ability, so that the surface of the finger is treated with the hydrophilic polymer to form a water-insoluble polymer coating containing a germicide ( Hereinafter, a polymer coating) will be formed.

Since the sterilizing agent mixed at the same time is fixed to the polymer film thus formed on the surface of the finger, the sterilizing agent is physically removed from the surface of the finger by contact with an object. It is less likely to be lost, and the rate at which the fungicide is inactivated by secretions from the skin surface is slowed down. Therefore, the sustainability of the disinfectant effect is significantly improved compared to the case where no polymer is contained, and
Even if the disinfectant alone is sticky like a disinfectant such as povidone iodine, stickiness on the finger surface due to the disinfectant can be effectively prevented.

Further, since the hydrophilic polymer is insoluble in water, the disinfecting effect is not lost even if the fingers are wet with water, and the hydrophilic polymer can be sufficiently applied to the work that is frequently exposed to water. To do. On the other hand, the polymer coating can be removed by washing with soap and is convenient as a hand sanitizer. Furthermore, since it is a hydrophilic polymer,
It is characterized by high biocompatibility and good water retention. Therefore,
It has little effect on the skin and also has the effect of preventing rough hands.

Further, according to the hand disinfection method according to the present invention, the surface of the finger is treated with the above-mentioned composition for hand disinfection by a quick-drying rubbing disinfection method or a spray method. The strong bactericidal effect of the system solvent is exhibited, and after the alcoholic solvent has evaporated, the water-insoluble polymer film containing the bactericide component formed on the surface of the finger has an excellent bactericidal effect. It will be demonstrated. Since the polymer film formed here is insoluble in water and the bactericide is fixed therein, the bactericidal effect is maintained for a long time. Therefore, according to the disinfection method of the present invention, it is possible to easily perform durable finger disinfection, and it is possible to eliminate the risk of infection to both the patient and the medical staff during surgery. Further, it is not necessary to wipe the fingers with a towel or the like, and the effect of preventing nosocomial infection can be enhanced.

[0019]

Concrete Structure The hydrophilic polymer constituting the composition for hand disinfection according to the present invention is used for the purpose of immobilizing the bactericide contained in the composition for hand disinfection after the disinfection treatment. However, as such a hydrophilic polymer, a homopolymer of 2-hydroxyethyl methacrylate, a copolymer of 2-hydroxyethyl methacrylate and another monomer, a cellulose derivative such as polyvinyl alcohol or hydroxypropyl cellulose is added to water. Insoluble substances are used. As the hydrophilic polymer, those soluble in an alcohol solvent such as ethanol, isopropanol, or those obtained by adding water to them are used. As the other monomer copolymerizable with the 2-hydroxyethyl methacrylate, vinyl acetate is used for the purpose of increasing the flexibility of the coating, and methacrylic acid or acrylic is used for the purpose of increasing the water absorption of the coating. In addition to the acid or the like, acrylamide, N, N'-dimethylacrylamide, alkyl acrylate, alkyl methacrylate, styrene or the like can be used in a small amount. And in the case of a copolymer of 2-hydroxyethyl methacrylate and vinyl acetate,
The component ratios are 2-hydroxyethyl methacrylate: 30 to 100% by weight, vinyl acetate: 0 to 70% by weight.
Is desirable, and in the case of a copolymer of 2-hydroxyethyl methacrylate and methacrylic acid or acrylic acid, the component ratio is 2-hydroxyethyl methacrylate: 8
0-100 mol%, methacrylic acid or acrylic acid: 0
20 mol% is desirable.

In addition, when a homopolymer of 2-hydroxyethyl methacrylate or a copolymer of 2-hydroxyethyl methacrylate and the above-mentioned other monomer is used as the hydrophilic polymer constituting the composition of the present invention, the weight of the polymer is increased. The coalescence preferably has a weight average molecular weight of about 5,000 to 1,000,000, more preferably about 10,000 to 300,000. If the weight average molecular weight is less than 5,000, the polymer film formed after the disinfection treatment of the fingers becomes sticky, while if it exceeds 1,000,000, the solubility in alcoholic solvents deteriorates. is there.

When polyvinyl alcohol is used as the hydrophilic polymer, its saponification degree is usually required to be 10 to 50 mol%, particularly 2
It is preferably 0 to 40 mol%. Saponification degree is 10
If it is less than mol%, the effect of enhancing the uniformity of the polymer coating formed will be insufficient, and if it exceeds 50 mol%, the water resistance of the polymer coating formed will be significantly reduced. In addition, the degree of polymerization is preferably about 300 to 2000, and particularly preferably 400 to 1500. If the polymerization degree is less than 300, the water solubility of the polymer film may increase, and if it exceeds 2000, the viscosity of the hand sanitizing composition becomes high and it is difficult to handle.

As the bactericide constituting the composition for hand disinfection according to the present invention, either a water-soluble bactericidal agent or a water-insoluble bactericidal agent can be used alone or in combination. Water-soluble fungicides include benzalkonium chloride, benzethonium chloride, chlorhexidine gluconate, alkyldiaminoethylglycine hydrochloride, povidone-iodine, and the like, and water-insoluble fungicides include Irgasan D
P300 (Switzerland: manufactured by Ciba-Geigy Co., Ltd.
4,4'-trichloro-2'-hydroxydiphenyl ether), chlorhexidine hydrochloride and the like. Among these, one kind or a combination of two or more kinds is used, but the water-insoluble bactericide does not dissolve in water,
Since the durability of the disinfectant effect is particularly good, the sustainability of the disinfectant effect is further improved by using the water-insoluble disinfectant together with the water-soluble disinfectant.

As the sterilizing agent, povidone-iodine or the like, which is conventionally used in the quick-drying rubbing disinfection method, causes stickiness on the surface of the fingers, even when it is used in the present invention. According to such a finger disinfecting composition and a finger disinfecting method using the same, as with other disinfectants, the finger does not cause any stickiness, and the film formed on the finger surface gives a dry feel. When using povidone-iodine as a hand sanitizer, the usability is improved. Also, Irgasan DP3
When 00 (2,4,4'-trichloro-2'-hydroxydiphenyl ether main component) is used as a bactericide, it is difficult to elute from a polymer film which is soluble in ethanol and insoluble in water, and has a disinfecting effect. Excellent in sustainability. When chlorhexidine hydrochloride is used as a bactericide, it is insoluble in both ethanol and water, so that it is used by dispersing it in an alcohol solvent.

Since such Irgasan DP300 is not sufficiently sensitive to Pseudomonas bacteria, benzalkonium chloride, polyhexamethylene biguanide, a silver-based inorganic antibacterial agent [eg, zeolite loaded with silver ions by ion exchange] (Manufactured by Shinagawa Fuel Co., Ltd.), zirconium phosphate carrying silver by ion exchange (manufactured by Toagosei Co., Ltd.), silicon oxide (SiO ₂ ) adsorbed silver complex (manufactured by Matsushita Electric Industrial Co., Ltd.) Etc.] and the like are also preferably used. Also, Irgasan DP30
By using a fatty acid soap in combination with 0, the susceptibility to Pseudomonas can be increased.

As the alcohol solvent for dissolving the hydrophilic polymer, ethanol, isopropanol or the like may be used. And from the viewpoint of bactericidal effect,
When using ethanol, the ethanol concentration should be 50
The ethanol is preferably 90 to 90% by weight, and more preferably ethanol having an ethanol concentration of 70 to 85% by weight. When isopropanol is used, its concentration is preferably 50 to 80% by weight, and more preferably 50 to 70% by weight. Among them, the most desirable alcohol solvent has an ethanol concentration of 70 to 85.
It is a disinfecting ethanol of weight%.

By the way, the hydrophilic polymer used in the present invention has the effect of imparting water retention to the fingers and preventing rough hands, but a water-soluble or water-insoluble skin protecting agent may be further added. As the water-soluble skin protectant, sodium 2-pyrrolidone-5-carboxylate, polyamino acid condensate, urea, lecithin, sodium lactate, glycerin,
There are diglycerin, polyglycerin, sorbit, polyethylene glycol, cholesterol, allantoin, coconut oil fatty acid polyoxyethylene glyceryl, hyaluronic acid, chitosan, etc., and water-insoluble skin protectants include sodium stearate, isobutyl adipate, etc. is there. In the present invention, these skin protectants are advantageously used alone or as a mixture.
It is particularly preferable to add an oily substance that is insoluble in water and soluble in ethanol for disinfection, such as sodium stearate, from the viewpoint of durability of hand disinfection and prevention of rough hands. The concentration of these skin protectants is preferably 0.05 to 2% by weight.

Furthermore, when a coloring agent is added to the composition for hand disinfection according to the present invention, it can be determined whether or not the disinfectant is evenly adhered to the finger, and whether or not the disinfectant can be washed off afterwards. As this colorant, a pigment or dye that is not toxic to the living body is used. For example, Alphazurin FG (Blue No. 205), Alizurin Purple S
S (Purple No. 201), Sudan Blue B (Blue 403)
No.), Alizulol Purple (purple No. 401), Resor Rubin B (red No. 201), indigo, etc. can be used. The concentration of these coloring agents is 0.00
5 to 0.5% by weight is preferable.

In the composition for hand disinfection according to the present invention, the hydrophilic polymer is dissolved in the alcoholic solvent, and the bactericide and, if necessary, the skin protectant and / or the coloring agent. It is prepared by mixing, dispersing or dissolving the agents. Of course, a hydrophilic polymer, a bactericide, and, if necessary, a skin protectant and / or a coloring agent are simultaneously added to an alcohol solvent to be dissolved or dispersed therein, or a hydrophilic polymer solution polymerized in the solvent. , A bactericide and an alcohol solvent, and if necessary, a skin protectant and / or
It goes without saying that even if the intended composition for hand disinfection is prepared by adding a coloring agent, it does not matter at all.

In the composition for hand disinfection according to the present invention prepared as described above, the concentration of the hydrophilic polymer in the composition is usually 0.2 to 5% by weight, preferably 0. It is set to 5 to 4% by weight. And, particularly preferably, it is 1 to 3% by weight. This is because when the polymer concentration is less than 0.2% by weight, the effect of immobilizing the bactericide by the polymer coating becomes insufficient, while
If it exceeds 5% by weight, the rigidity of the polymer coating is increased, and there is a risk of causing a stiff discomfort associated with the movement of fingers.

Further, in such a composition for hand disinfection,
The concentration of fungicide in the composition usually depends on the type of fungicide used. For example, benzalkonium chloride,
When benzethonium chloride or chlorhexidine gluconate is used as a bactericide, the amount is usually 0.01 to 1% by weight, preferably 0.1 to 0.3% by weight. When povidone iodine is used as a bactericide, it is usually 0.1 to 4% by weight (effective iodine concentration 0.01
~ 0.4 wt%), preferably 0.3-2 wt%
(Effective iodine concentration is 0.03 to 0.2% by weight).
Furthermore, Irgasan DP300 (main component is 2,4,4'-
When trichloro-2'-hydroxydiphenyl ether) is used as a bactericide, it is usually 0.3 to 3% by weight.
When chlorhexidine hydrochloride is used as a germicide, the content is usually 0.02 to 0.5% by weight, preferably 0.05 to 0.3% by weight.

When disinfecting a finger using the composition for hand disinfection according to the present invention thus obtained, a method of forming a polymer film containing a bactericide on the surface of the finger is used. Any method can be adopted if it exists. For example, if the rubbing method is adopted, about 3 ml of the composition for hand disinfection according to the present invention is taken in the palm and the polymer film can be formed by rubbing both hands well until it is dried. It is also possible to form a polymer film on the surface of a finger by spraying a composition for hand sterilization by a spray method and then drying it.
