Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning article that has a good cleaning effect in toilets and the like and has improved water-disintegrability.

[Conventional technology and its problems]

Traditionally, toilets have been filthy, so special rags have been used to clean them. Recently, disposable, water-disintegratable toilet seat cleaners that can be flushed down the toilet have become commercially available.

These products are made by impregnating binder-free water-disintegrating paper, such as toilet paper, with a cleaning agent consisting of a highly concentrated water-soluble solvent, a surfactant, and a small amount of water (Japanese Patent Laid-Open No. 63-40555). JP-A No. 61-296159, JP-A No. 61-296159, JP-A No. 61-296159, JP-A No. 61-296159, JP-A No. 61-296159, JP-A-61-296159, etc. 63-50600, etc.) has no problem with water disintegration, but because it uses a highly concentrated solvent, there are problems with solvent odor, flammability, storage stability, etc. Therefore, there is a problem with cleaning performance.

The latter does not have these problems, but its water-disintegrability is inferior to the former.

The latter does not have many problems with water disintegration in normal use, but
For example, when the toilet flush is weak, when used in high-rise apartment buildings,
Alternatively, if a large amount of cleaning products are flushed away at once, there is a concern that the drain pipe may become temporarily clogged.

[Means to solve the problem]

In order to solve this problem, the present inventors have conducted intensive studies on the composition of a cleaning agent to be impregnated into water-disintegratable paper, and found that a water-insoluble oily liquid component is added to a mixed aqueous solution of water, a water-soluble solvent, and a surfactant at a specific ratio. The present invention was completed based on the discovery that the water-disintegrability of cleaning articles can be improved by adding a small amount of .

That is, the present invention includes (a) 10 to 40% by weight of a water-soluble solvent (
b) Water-insoluble oily substance 0.03-3% by weight (c
) surfactant 0.1 to 5% by weight (d) water balance A water-disintegratable cleaning article is provided in which water-disintegratable paper is impregnated with a cleaning agent consisting of (d) water balance.

The water-soluble solvent (a) used in the present invention includes monohydric lower alcohols such as ethanol, methanol, and propatool; ethylene glycol, diethylene glycol,
Dihydric lower alcohols such as polyethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, hexylene glycol; glycerin,
Polyhydric alcohols such as sorbitol; or mono- or diethers of the above alcohols and monohydric lower alcohols such as methanol, ethanol, propatool, butyl alcohol; or one or more esters of the above alcohols and lower fatty acids. used in combination.

The water-soluble solvent as component (a) is used in the form of an aqueous solution, and is added in an amount of 10 to 40% by weight in the cleaning agent impregnated into the water-disintegratable paper.
It is blended. If the amount of component (a) is less than 10% by weight, the strength of the water-disintegrable paper cannot be maintained sufficiently, and if it exceeds 40% by weight, the detergency against water-soluble stains will be reduced.

The water-insoluble oily substance (b) used in the present invention includes:
Plant essential oils such as orange oil, lemon oil, fern oil, grove oil, cananga oil, turpentine oil, pine oil, etc., or their constituent monoterpenes or sesquiterpenes such as D- or L-limonene, α- or β-pinene Preferred are hydrocarbons, paraffin hydrocarbons having 8 to 16 carbon atoms, triglycerides, and the like. The water-insoluble oily substance 0)) is blended in an amount of 0.03 to 3% by weight in the cleaning agent with which the water-disintegratable paper is impregnated.

If the amount of component (b) is less than 0.03% by weight, water disintegration cannot be improved, and if it exceeds 3% by weight, problems such as stickiness will occur.

The surfactant (c) used in the present invention includes anionic surfactants, nonionic surfactants, cationic surfactants, and amphoteric surfactants. In particular, amine oxide having one or two lower alkyl groups or alkyl groups having 8 to 22 carbon atoms, sulfobetaine or hydroxysulfobetaine having alkyl groups having 8 to 22 carbon atoms, and alkyl groups having 8 to 22 carbon atoms. Ampholytic surfactants such as carbobetaine; alkyl sulfates having 8 to 22 carbon atoms; alkyl ether sulfates having an alkyl group having 8 to 22 carbon atoms and 1 to 30 moles of ethylene oxide; Anions such as alkylbenzene sulfonates having an alkyl group, α-sulfo fatty acid ester salts having 8 to 22 carbon atoms, alkyl (or alkenyl) succinates having 6 to 22 carbon atoms, and paraffin sulfonates having 8 to 22 carbon atoms. Surfactant; polyoxyalkylene having an alkyl group having 8 to 22 carbon atoms (often polyoxyethylene, polyoxypropylene, or a mixture of both); nonionic surfactant such as glycol ether; carbon number 8
It is desirable to use a cationic surfactant such as a quaternary ammonium salt having one alkyl group of 1 to 14.

The surfactant (c) is blended in an amount of 0.1 to 5% by weight in the cleaning agent with which the water-disintegratable paper is impregnated.

A cleaning agent for impregnating water-disintegratable paper is prepared by adding a balanced amount of water (d) to the components (a) to (c) above.

The water-disintegratable paper used in the present invention is made of one or more mixed fibers selected from natural fibers such as wood valve fibers and non-wood valve fibers, or synthetic fibers such as rayon fibers, and a natural polymer or synthetic polymer. It is produced by a conventional method such as a wet method or a dry method using a binder consisting of one or more kinds selected from the following.

As a binder, a polymer having a carboxyl group as an anion group is best from the viewpoint of wet strength and water disintegrability of the water-disintegratable paper, but polymers having a sulfone group or a phosphate group as an anion group can also be used. Carboxymethyl cellulose is most suitable as the polymer having carboxyl groups, but polyacrylic acid, polymethacrylic acid, polymaleic acid, or copolymers with monomers copolymerizable with these can also be used. Counter ions for polymers having anionic groups include alkali metals,
One or more metal ions selected from alkaline earth metals, manganese, cobalt, zinc, and nickel are preferred, with alkaline earth metals and zinc being particularly preferred.

The water-disintegratable paper thus obtained may be used as is, but
The cleaning article of the present invention is preferably embossed.

In the water-disintegratable cleaning article of the present invention, an aqueous detergent solution comprising the components (a) to (d) described above is applied to the water-disintegratable paper at a rate of about 100 to 2
Obtained by impregnating 50% by weight (0% 1f).

In addition to the above-mentioned components (a) to (d), components such as a disinfectant and a deodorant can be added to the cleaning agent used in the present invention to be impregnated into the water-disintegratable paper.

〔Effect of the invention〕

According to the present invention, an excellent water-disintegratable cleaning article can be obtained that has good water-disintegratability and does not cause clogging of drain pipes even if a large amount is flushed down the toilet or the like.
