Description

  The present invention relates to a wiping sheet used to wipe a human body or the like by impregnating a fiber sheet with a cleaning agent.

  For example, cleansing cotton belonging to quasi-drugs, “base cloth-impregnated cosmetics” belonging to cosmetics, and “wet tissue” belonging to miscellaneous goods as products for wiping away and cleaning dirt on the skin, specifically hands, fingers, and bodies. A wiping sheet or the like is known.

  As this wiping sheet, absorbent cotton, non-woven fabric, woven fabric, paper, or the like is impregnated with a chemical solution obtained by dissolving a chemical such as chlorhexidine gluconate in purified water, or contains a preservative, a disinfectant, or the like. Some have soaked with an aqueous solution.

  A sterilizing preservative is added to the chemical solution or aqueous solution used for such a wiping sheet, for example, in order to kill microorganisms and prevent their growth and prevent deterioration and deterioration. And as a bactericidal preservative, for example, when used as a chemical solution for a wiping sheet such as paraben, benzoic acid, benzoate, benzalkonium chloride, benzethonium chloride, cetylpyridium chloride, etc. Some are used.

  This bactericidal and preservative is considered to have low irritation to the human body and high antibacterial and antiseptic properties. In particular, when a person with low skin resistance, such as an infant or an elderly person, uses these characteristics in a chemical solution or an aqueous solution used for a wiping sheet.

  However, in the chemicals and aqueous solutions used for the wiping sheet, the antibacterial properties and the irritation to the skin sometimes conflict with each other, and no single bactericidal preservative has been obtained that satisfies both. This is the current situation.

  Further, in the wiping sheet, it is desired that the feeling of use when the skin is wiped, specifically, the sticky feeling of the wiped portion, etc. is suppressed. It is necessary to select moisture-proofing agents, etc., that affect the feeling of use contained in the product, taking into consideration the safety to the human body and the like.

  The present invention provides a wiping sheet that suppresses irritation to the skin without impairing the bactericidal and antiseptic effect, and is excellent in feeling when used for wiping.

  In order to solve the above-mentioned problems, the inventors have conducted intensive studies, and as a result, reconsidered the selection and ratio of each material component contained in the cleaning agent, thereby reducing the water contained in the cleaning agent. By increasing the amount and reducing the content of bactericidal preservatives and moisturizing agents, it is possible to obtain a cleansing agent that can suppress irritation to the skin without impairing the bactericidal and preservative effect and can suppress the sticky feeling caused by the chemical when wiped. As a result, the present invention has been completed.

In the wiping sheet according to the present invention, a fiber sheet is impregnated with a cleaning agent, and the cleaning agent comprises water , a bactericidal preservative, a water-soluble humectant, and a solubilizing agent . The wiping sheet contains 100 parts by weight of the entire cleaning chemical, 99.18 parts by weight or more and 99.49 parts by weight or less of water, and contains more water than before. In contrast, wiping sheet, as a minimum range obtained bactericidal preservative effect, as a bactericide preservative, using a salt of cetylpyridinium and methyl parahydroxybenzoate and ethyl parahydroxybenzoate, overall these bactericides preservatives The content of 0. 2 3 parts by weight or more and 0.27 parts by weight or less. In addition, the wiping sheet is a minimum range that maintains the wet state of the wiping sheet and suppresses deterioration of the feeling of use, and the content of the water-soluble humectant is 0.05 parts by weight or more and 0.35 parts by weight or less. There, as a solubilizing agent, the content of the polyoxyethylene hydrogenated castor oil is 0.2 parts by weight.

In the present invention, the content of the sterilizing preservative and the humectant is increased by using a ratio of 99.18 parts by weight or more and 99.49 parts by weight or less of water and increasing the relative water ratio in 100 parts by weight of the cleaning agent. It is possible to reduce the irritation to the skin and the sticky feeling caused by the cleaning agent. In addition, the present invention provides a 0. 2 3 parts by weight or more, containing a bactericide preservative in a proportion of less than 0.27 parts by weight to the salt of cetylpyridinium and methyl parahydroxybenzoate and ethyl parahydroxybenzoate, 0.05 parts by weight or more, 0.27 weight Since it contains a water-soluble humectant in a proportion of less than or equal to 0.2 parts by weight of polyoxyethylene hydrogenated castor oil as a solubilizing agent, the wiping sheet is kept wet for a long time while having a bactericidal and antiseptic effect. It can be held over and deterioration of the feeling of use can be prevented.

  Hereinafter, the wiping sheet to which the present invention is applied will be described in detail.

  The wiping sheet to which the present invention is applied is used to wipe a human body or an object by impregnating a fiber sheet with a cleaning agent. Specifically, when used on the human body, the wiping sheet is a clean cotton belonging to quasi-drugs, “base cloth-impregnated cosmetics” belonging to cosmetics, miscellaneous goods, etc. Such as “wet tissue” to which it belongs.

  As the fiber sheet used for the wiping sheet, for example, a fabric in which natural fibers or synthetic fibers are formed on a woven fabric, a nonwoven fabric, or a knitted fabric can be used. Among these, a cloth made of a nonwoven fabric is most preferably used because of versatility and cost. Specifically, examples of natural fibers include cotton, silk, hemp, wool, and pulp. Examples of synthetic fibers include polyethylene terephthalate, polyester, polypropylene, polyethylene, acrylic, nylon, vinylon, polyvinyl chloride, and polyurethane. And rayon. Moreover, the cloth which mixed these natural fiber and synthetic fiber can be used.

  Furthermore, as the fiber sheet, it is also possible to use a fabric made of a non-woven fabric or the like that does not use a binder or the like, which is proposed in, for example, JP-A-9-78419. Specifically, a high-pressure water jet is applied to a nonwoven fabric composed of fine pulp fibers having a predetermined water retention and discontinuous regenerated cellulose fibers or synthetic fibers having a predetermined fiber length, and the fibers are entangled. It is also possible to use a water-disintegrating nonwoven fabric that has sufficient strength to withstand use in a dry state and retains the web shape in a wet state with a liquid, and that disintegrates into a fiber form very easily and quickly when immersed in a large amount of water. Is possible.

The cleaning agent impregnated in the fiber sheet is at least water, a sterilizing and preserving agent that imparts a sterilizing and preserving effect to the wiping sheet, a moisturizing agent that maintains the wet state of the wiping sheet, and a solubilizing agent. Contains.

  For example, distilled water or purified water is used as the water contained in the cleaning agent. And in this cleaning chemical | medical agent, the quantity of the water contained in a chemical | medical agent is increased, and it is trying to restrain content of other materials. The cleansing agent suppresses the irritation to the skin by suppressing the amount of the bactericidal preservative and the moisturizing agent, thereby suppressing the sticky feeling caused by the agent and preventing the deterioration of the feeling of use. Moreover, in this cleaning chemical | medical agent, cost reduction can be achieved by suppressing content of materials other than water.

  Specifically, the water is contained at a ratio of 94.87 parts by weight or more and 99.49 parts by weight or less based on 100 parts by weight of the whole cleaning drug.

  If the proportion of water is less than 94.87 parts by weight with respect to the entire cleaning agent, the proportion of agents other than water, such as bactericidal preservatives and moisturizing agents, increases, and there is a risk that the cleaning agent will be highly irritating to the skin. . Further, in this case, there is a risk of feeling sticky when wiping. On the other hand, if the proportion of water exceeds 99.49 parts by weight with respect to the entire cleaning agent, the proportion of agents other than water, such as bactericidal preservatives and moisturizers, decreases, and the bactericidal / preservative effect cannot be obtained. There is a possibility that the feeling of use of the wiping sheet may be impaired.

  Therefore, in the cleaning agent, the entire cleaning agent is 100 parts by weight, and the amount of water contained is in the range of 94.87 parts by weight or more and 99.49 parts by weight or less without impairing the bactericidal / preservative effect. It becomes possible to provide a wiping sheet that suppresses irritation to the skin and has excellent usability when wiped.

The bactericidal / preservative contained in the cleaning agent includes, for example, paraoxybenzoic acid esters such as methyl paraoxybenzoate (methylparaben), ethyl paraoxybenzoate (ethylparaben), propylparaben, butylparaben, benzoic acid and its sodium salt, Salicylic acid and its sodium salt, sorbic acid and its potassium salt, acid compounds such as dehydroacetic acid and its sodium salt, phenolic compounds such as isopropylmethylphenol and resorcin, halogenated phenolic compounds such as hexachlorophene and triclosan, triclocarban , Carbanilide compounds such as halocarban, cationic compounds such as benzalkonium chloride, benzethonium chloride, cetylpyridinium chloride, chlorhexidine gluconate, chlorhexidine hydrochloride, etc. Door can be. In addition to these compounds, for example, compounds such as phenoxyethanol, chlorobutanol, zinc pyrithione, zinc paraphenolsulfonate, hinokitiol, and the like can be given. And it mixes with any 1 type or multiple types of the compounds mentioned above. Of the above-mentioned sterilizing and preserving agents, for example, paraoxybenzoic acid esters and cationic compounds that can impart a sterilizing and preserving effect to the wiping sheet in a small amount are suitable, methyl paraoxybenzoate, ethyl paraoxybenzoate, Cetylpyridinium chloride is preferred. In the present invention, cetylpyridinium chloride, methyl paraoxybenzoate, and ethyl paraoxybenzoate are used as cleaning agents.

The total amount of the cleaning agent is 100 parts by weight, and is contained in a proportion of 0.03 parts by weight or more and 0.27 parts by weight or less based on the whole cleaning agent.

If the proportion of the sterilizing and preserving agent is less than 0.03 parts by weight based on the entire cleaning agent, it is difficult to impart the sterilizing and preserving effect to the wiping sheet because the sterilizing and preserving agent contained in the agent is too small. Become. On the other hand, if the proportion of the sterilizing / preserving agent is more than 0.27 parts by weight with respect to the entire cleaning agent, there is a possibility that the sterilizing / preserving agent contained in the agent is too much and the cleaning agent is highly irritating to the skin.

Accordingly, in the cleaning agent, the entire cleaning agent is 100 parts by weight, and the amount of the sterilizing and preserving agent contained is 0.03 parts by weight or more and 0.27 parts by weight or less, thereby impairing the sterilizing and preserving effect. It becomes possible to provide the wiping sheet which can suppress irritation | stimulation with respect to skin without this.

  Moreover, in a cleaning chemical | medical agent, at least a water-soluble humectant is contained as a humectant.

  Examples of the water-soluble humectant contained in the cleaning agent include sodium lactate, sorbitol, sodium pyrrolidonecarboxylate (PCA-Na), trimethylglycine, sodium hyaluronate and the like, any one or more of these. Are mixed and used. Of the water-soluble humectants described above, sodium lactate and sodium pyrrolidonecarboxylate are particularly suitable.

The total amount of the cleaning chemical is 100 parts by weight, and the water-soluble humectant is contained in a proportion of 0.05 parts by weight or more and 4.7 parts by weight or less based on the whole cleaning chemicals.

If the proportion of the water-soluble humectant is less than 0.05 parts by weight with respect to the entire cleaning agent, the feeling of use when wiped may be impaired. On the other hand, if the ratio of the water-soluble humectant to the entire cleaning agent exceeds 4.7 parts by weight, the amount of the water-soluble humectant contained in the agent is excessive, and a sticky feeling is generated when wiping is performed. There is a possibility that the feeling of use of the sheet is impaired.

Therefore, in the cleaning chemical, the wet state of the wiping sheet is maintained and the stickiness by the chemical is controlled by setting the amount of the water-soluble humectant contained in the range of 0.05 parts by weight or more and 4.7 parts by weight or less. It is possible to provide a wiping sheet having a reduced feeling and excellent usability.

Further, in this cleaning agent, the above-mentioned water, bactericides preservatives, other humectants, such as polio Kishiechiren hydrogenated castor oil, solubilizing agents such as polyoxyethylene oleyl ether, Kurinsushido, gum tragacanth, pectin, alginates, Cellulose derivatives, acrylic acid polymers, pea gums, labnites, hyaluronic acid salts, chondroitinic acid thickeners, paraffin sulfonate zinc, vitamins, amino acid derivatives and other medicinal ingredients, fragrances, dyes, buffers, chelating agents, A pH adjusting agent, an antioxidant, an ultraviolet ray inhibitor and the like can be contained depending on the purpose of use of the wiping sheet. In the present invention, polyoxyethylene hydrogenated castor oil is used as the cleaning agent .

  Furthermore, in the cleaning agent, in addition to the above-described moisturizing agent, for example, an oily moisturizing agent or an alcohol moisturizing agent can be added. Specific examples of the oily moisturizer include castor oil, olive oil, grape seed oil, cacao oil, coconut oil, coconut oil, tree wax, jojoba oil, avocado oil, and other vegetable oils, beeswax, whale wax, lanolin, carnauba wax. Waxes such as candelilla wax, hydrocarbons such as squalane, liquid paraffin, microcrystalline wax, ceresin wax, paraffin wax, petrolatum, lauric acid, myristic acid, stearic acid, oleic acid, isostearic acid, behenic acid, etc. Fatty acids, cetanol, stearyl alcohol, hexyl decanol, octyldodecanol, higher alcohols such as lauryl alcohol, esters such as isopropyl myristate, octyldodecyl myristate, octyldodecyl oleate, cholesteryl oleate Sodium polyacrylate, and the like cellulose or mixtures thereof. Examples of alcohol humectants include ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, 3-methyl-1,3-butanediol (isoprene glycol), 2,2-dimethylpropane- 1,3-diol, hexylene glycol, 2,4-dimethylpentane-2,4-diol and the like. And these oil-based humectants and alcohol-type humectants are added in appropriate amounts in a state where one or a plurality of types are mixed according to the purpose of use of the wiping sheet.

  The wiping sheet having the above-described configuration is sealed in a water vapor impermeable soft packaging material by a method such as heat sealing so as to be convenient for storage, carrying and use, for example, and is made into one package. This one package can take out the included wiping sheet from an outlet having an open / close lid. Examples of flexible packaging materials that store wiping sheets include resin films commonly used for packaging applications such as pharmaceuticals and retort foods that require moisture-proof packaging, composite films of metal foil and resin films, so-called laminate films, etc. Can be used.

  In the wiping sheet, the soft packaging material is, for example, a composite film of polyester (PET), aluminum (Al) foil and unstretched polypropylene (CPP), or a composite of biaxially stretched nylon (Ny), Al foil and CPP. As long as it has both heat resistance and toughness, such as a film, it is possible to perform high-pressure steam sterilization in a single package.

  In addition, since the outlet for taking out the wiping sheet can prevent the wiping sheet from being dried, it can be repeatedly opened and sealed, for example, a flap label made of a composite material of biaxially oriented polypropylene (OPP) and PET, It is opened and closed by a plastic opening / closing lid.

The wiping sheet described above is composed of 94.87 parts by weight or more and 99.49 parts by weight or less of water in 100 parts by weight of the cleaning agent, and by increasing the relative water ratio in the entire cleaning agent, The content of the bactericidal preservative and the moisturizing agent can be reduced, and the irritation to the skin and the stickiness caused by the cleaning agent can be suppressed. In addition, since the present invention contains a bactericidal and preservative in a proportion of 0.03 parts by weight or more and 0.27 parts by weight or less based on the whole cleaning agent, it has a bactericidal and antiseptic effect and suppresses irritation to the skin. can do. In addition, the present invention contains a water-soluble humectant in a proportion of 0.05 parts by weight or more and 4.7 parts by weight or less based on the total amount of the cleaning agent, so that the sticky feeling due to the agent is suppressed and the wiping sheet is moistened. The state can be maintained for a long period of time, and deterioration of the feeling of use can be prevented.

  Moreover, in the wiping sheet, since the content of materials other than water in this cleaning agent is suppressed, cost reduction can be achieved.
