Description

  The present invention relates to a sterilizing cleaning article.

Conventionally, cleaning articles used in toilets, etc., have been used water disintegrating paper that is disintegrated by exposure to a large amount of water, such as flowing into the toilet after use, and impregnated with water-soluble cleaning chemicals (for example, patents) Reference 1).
In the case of sheet-like cleaning articles used on stainless steel and tile hard surfaces such as kitchens, living rooms, toilets, and bathtubs, surfactants, alkaline agents, and certain water-soluble organic solvents are used in terms of detergency and cleaning finish. Is used (see Patent Document 2).
In particular, cleaning articles used in toilets have anti-odor measures against bad odors such as manure odor. This anti-odor measure not only masks with fragrance, but also inhibits the activity of β-glucuronidase because β-glucuronidase derived from bacterial cells acts on urine to increase phenolic compounds and indoles that cause malodor. It has been proposed to use a macrocyclic musk compound (see Patent Document 3).

The present inventors have provided cleaning properties for sheet-like cleaning articles used for conventional hard surfaces such as kitchens, living rooms, toilets, and bathtubs, and particularly for skin cleaning around the anus, urinary tract, and vulva used in toilets. In addition to the deodorizing property, it was considered important to positively impart sterilizing properties against bacteria that could be pathogenic bacteria such as Escherichia coli and Staphylococcus aureus, and to provide excellent sterilizing properties.
The present inventors have examined the sterilization property of the sheet-like cleaning article using the hydrolytic paper that is hydrolyzed by exposure to a large amount of water after use. Hydrolytic paper contains a water-soluble binder having carboxy groups such as pulp and carboxymethylcellulose (CMC). In this binder, when a divalent or higher metal ion such as calcium is present, the carboxy group of the binder molecule forms a water-insoluble salt between the two molecules, and the binder molecule is cross-linked. Thereby, the sheet-like cleaning article maintains the cleaning strength when wet. For this reason, the strength increases as the amount of divalent or higher metal ions increases.
However, it has been found that the addition of divalent or higher metal ions inhibits the bactericidal activity of surfactants exhibiting a bactericidal effect.

  Therefore, an object of the present invention is to provide a disinfecting cleaning article that has both disinfecting properties and strength.

The present invention relates to a sterilizing cleaning article obtained by impregnating a base sheet having a basis weight of 20 to 120 g / m ² containing 80% by mass or more of a cellulose fiber with a liquid cleaning composition, and the liquid cleaning composition The organic acid (a) is 0.01 to 0.50% by mass, the surfactant (b) is 0.1 to 1.0% by mass, and the divalent or higher metal ion compound (c) is 0.5 to 5.

<Divalent or higher metal ion compound (c)>
The metal ion compound (c) used in the present invention is an ionic (bonding) compound containing at least a divalent or higher metal ion as a cation. The valence of the metal ion is known to be 2-7. However, in the present invention, 2 or 3 is preferable, and 2 is particularly preferable.
In the present invention, the metal of the divalent metal ion is particularly preferably a metal selected from the group consisting of alkaline earth metals, manganese, zinc, cobalt and nickel. In the present invention, the metal of the divalent metal ion may be used alone or in combination of two or more.
The divalent or higher valent metal ions sufficiently bond between the constituent fibers of the base sheet and develop a strength (particularly wet strength) that can withstand cleaning operations, and water disintegration is sufficient.
In the present invention, the divalent or higher-valent metal ion is preferably calcium, strontium, barium, zinc, cobalt, or nickel, and among these, zinc is particularly preferable.
The use of the metal ion compounds listed above is particularly preferable because a higher wet strength of the substrate sheet (sterilizing cleaning article) can be obtained and the cleaning operation using the sanitizing cleaning article can be performed successfully.

The divalent or higher valent metal ion compound (c) is a compound that dissociates in the liquid detergency composition to generate metal ions, and is a metal ion hydroxide, chloride, sulfate, nitrate, carbonate, formic acid. It can be used by adding to a liquid detergency composition in the form of a water-soluble metal salt such as a salt or acetate.
In particular, metal ions having a valence of 2 or more include molecules such as cellulose fibers in the base material sheet used in the disinfectant cleaning article of the present invention, and molecules such as binders contained therein, which are ion-bonded and chelated between molecules. By causing ionic interaction such as coordination, these molecules can be cross-linked, and the wet strength of the substrate sheet can be increased.

Examples of functional groups that interact with metal ions include dissociable groups such as carboxy groups, sulfo groups, low pKa hydroxy groups, mercapto groups, sulfonamido groups, hydroxy groups, mercapto groups, alkoxy groups, and alkylthio groups. A group having a lone electron pair necessary for coordination, such as an amino group, a group having a carbonyl bond, and the like.
Among these, the dissociable group strongly interacts with the metal ion to form a water-insoluble salt and has an excellent crosslinking effect, and the carboxy group is particularly preferable.
In the present invention, it is sufficient that the metal ion is added in an amount of 1/4 mol or more, particularly 1/2 mol or more with respect to 1 mol of the interacting functional group (particularly carboxy group). It is preferable from the viewpoint of causing a reaction.

In the present invention, in order to achieve both the wet strength of the sterilizing cleaning article (for example, sheet) and the sterilizing effect of the surfactant (b), the content of the divalent or higher metal ion compound (c) is liquid detergency. In the composition, it is 0.5 to 5.0% by mass, preferably 0.5 to 4.0% by mass, and more preferably 1.0 to 3.0% by mass.
When the content of the divalent or higher valent metal ion compound (c) is less than 0.5% by mass, the wet strength of the sheet is inferior.

In the present invention, the compatibility between the sterilization property and the strength is considered to be due to the organic integrated action of the organic acid, the surfactant, and the metal ion compound that coexist at a specific ratio.
That is, as described above, the strength of the sterilizing cleaning article is enhanced by metal ions generated from the metal ion compound by ionic interaction with cellulosic fibers and the like. In such a disinfecting cleaning article, the surfactant (b) (particularly, the cationic surfactant) is adsorbed or taken in the cell membrane of the microbial cell, and changes in physical properties of the cell membrane (fluidity of the cell membrane). The cell membrane of the microbial cell is destroyed by the increase, etc., and when the bivalent or higher valent metal ion is present, the microbial cell membrane of the surfactant (b) is present. Inhibits the adsorption to the bacteria and reduces the sterilization. However, when a specific amount of the organic acid (c) coexists with the metal ion, the organic acid (c) changes the cell of the microbial cell by internal permeation, thereby suppressing adsorption inhibition by the metal ion and surface activity. It is considered that the bactericidal action of the agent is effectively exhibited.
Here, when the organic acid (c) is in a non-dissociated state, it is easier to enter the microbial cells, and the liquid cleaning composition is effective as described above in that the above action is effectively achieved. It is preferable to keep the pH of the solution acidic.

<Perfume (d)>
In the present invention, it is preferable to add a fragrance (d) to the disinfecting cleaning article because a better odor eliminating effect is obtained and a preferable fragrance drifts after the odor eliminating.
The fragrance (d) may be a natural fragrance or a synthetic fragrance.

However, when the dirt is wiped off, it is necessary to have sufficient wet strength that can withstand the operation in the state of being impregnated with the liquid cleaning composition.
From such a viewpoint, in the present invention, it is particularly preferable that the base sheet contains a water-soluble binder having a carboxy group. By using a water-soluble binder having a carboxy group, it is easy to control water disintegration, and a base sheet that does not disintegrate in a small amount of water but rapidly disintegrates at the fiber level when discarded in a large amount of water is obtained.

The water-soluble binder having a carboxyl group is an anionic water-soluble binder that easily forms a carboxylate in water. Examples of such a binder include polysaccharide derivatives, synthetic polymers, and natural products.
Examples of the polysaccharide derivative include carboxymethyl cellulose or a salt thereof, carboxyethyl cellulose or a salt thereof, carboxymethylated starch or a salt thereof.
Examples of the synthetic polymer include an unsaturated carboxylic acid polymer or copolymer salt, and a copolymer salt of an unsaturated carboxylic acid and a monomer copolymerizable with the unsaturated carboxylic acid.
Examples of the unsaturated carboxylic acid include acrylic acid, methacrylic acid, itaconic acid, crotonic acid, maleic anhydride, maleic acid, and fumaric acid. Examples of the monomer copolymerizable with these include esters of these unsaturated carboxylic acids, vinyl acetate, ethylene, acrylamide, vinyl ether and the like. Particularly preferred synthetic polymers are those using acrylic acid or methacrylic acid as the unsaturated carboxylic acid. Specifically, polyacrylic acid, polymethacrylic acid, acrylic acid-methacrylic acid copolymer salt, acrylic acid or methacrylic acid. Examples thereof include a salt of a copolymer of an acid and an alkyl acrylate or an alkyl methacrylate.
Examples of natural products include sodium alginate, xanthan gum, gellan gum, tarragant gum, pectin and the like.

  Particularly preferred as the water-soluble binder having a carboxy group is carboxymethylcellulose (CMC) or an alkali metal salt thereof (for example, sodium salt) from the viewpoint of water decomposability and strength of the sheet.

  Content of the water-soluble binder which has a carboxy group becomes like this. Preferably it is 0.1-20 mass% with respect to the total mass of a base material sheet, More preferably, it is 1-15 mass%.

There is no restriction | limiting in particular in the method of including the water-soluble binder which has a carboxy group in a base material sheet, The internal addition method may be sufficient and the external addition method may be sufficient.
Examples of the internal addition method include a method in which a water-soluble binder is added in advance to the stock (fiber dispersion) when a base sheet is produced by a wet papermaking method. Examples of the external addition method include a method of forming a web (base sheet) containing cellulosic fibers and then adding a water-soluble binder to the web by an adding means such as spray coating.

  The base sheet may appropriately contain, for example, a wet paper strength enhancer, a release agent and the like as components other than fibers such as cellulose fibers and a water-soluble binder having a carboxy group.
