Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition for toilets and tiles, and more particularly, it has a sufficient cleaning power and is a safe composition for suppressing generation of chlorine when mixed with a chlorine-based cleaning agent. The present invention relates to a toilet / tile cleaning composition.

[0002]

2. Description of the Related Art Dirt adhering to toilet bowls and tiles in a toilet room, tiles in a bathroom, wash basin, etc. consists of calcium phosphate, iron oxide, fatty acid metal salts, organic substances secreted by the human body, etc. If it is done, it will be very difficult to remove. Conventionally, as a cleaning agent for removing these stains,
In addition to acidic cleaners containing hydrochloric acid as a main component, neutral or chlorine cleaners have been used.

However, although the acidic cleaning agent has an excellent cleaning effect, if a user mistakenly mixes it with a chlorine-based cleaning agent, a large amount of chlorine gas is generated, which is dangerous to the human body. There was a problem. On the other hand, the neutral detergent has no danger of generating chlorine gas, but has a poor detergency, and the chlorine-based detergent has problems in both detergency and generation of chlorine gas.

[0004]

DISCLOSURE OF THE INVENTION The present invention has excellent cleaning power against dirt on toilet tiles, and suppresses generation of chlorine gas when mixed with a chlorine-based cleaning agent while being acidic. It is intended to provide a safe toilet / tile cleaning agent.

[0005]

[Means for Solving the Problem] The present inventors have previously proposed a compound (halogen scavenger) having a series of halogen scavenging ability for suppressing the generation of chlorine when a chlorine-based bleaching agent and an acidic detergent are mixed. Heading and patent application (Japanese Patent Laid-Open No. 5-11154)
No. 6).

Subsequently, as a result of extensive studies to prepare a practical toilet / tile cleaning agent using this halogen scavenger, a specific halogen scavenger was selected and a mixture of a mineral acid and a surfactant was selected. It has been found that a safe acidic cleaner having excellent detergency and having suppressed generation of chlorine when mixed with a chlorine-based detergent can be obtained by blending this, and completed the present invention.

That is, the present invention comprises the following components (A)
(C) (A) Mineral acid 0.1 to 20% by weight, (B) Halogen scavenger selected from polyoxyethylene phenyl ether or polyoxyethylene alkylphenyl ether having an alkyl group having 1 to 4 carbon atoms 0 The present invention provides a toilet / tile cleaning composition comprising 0.1 to 30% by weight and (C) a surfactant of 0.1 to 20% by weight.

As the mineral acid which is the component (A) of the present invention,
Examples thereof include hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid and the like.
Of these, hydrochloric acid is preferable from the viewpoint of solubility in calcium salts and iron oxides, and it may be used in combination with other mineral acids or organic acids, if necessary. The amount of the component (A) added to the toilet / tile cleaning composition is 0.1 to 2
It is 0% by weight (hereinafter, simply indicated by "%"), preferably 1 to 10%.

The component (B) of the present invention is selected from polyoxyethylene phenyl ether and polyoxyethylene alkyl phenyl ether having an alkyl group having 1 to 4 carbon atoms, and any one kind or a combination thereof may be used. Two or more kinds can be used in combination.

The component (B) is produced, for example, by adding ethylene oxide to phenol or an alkylphenol having an alkyl group having 1 to 4 carbon atoms. Of these, specific examples of the alkylphenol include: Examples thereof include cresol, ethylphenol, propylphenol, t-butylphenol, xylenol, methylethylphenol, di-t-butylphenol and the like.

It is considered that the component (B) of the present invention reacts with the generated chlorine in an equimolar amount, so that it is advantageous that the molecular weight is small from the economical point of view. Further, polyoxyethylene phenyl ether is most preferable in consideration of the performance as a solvent. The number of moles of ethylene oxide added in the component (B) may be about 1 to 30, but from the viewpoint of economy, it is desirable that the number of moles is small as long as water solubility is not lost. The number of moles is preferably about 3-5.

The amount of the component (B) added to the toilet / tile cleaning composition is 0.1 to 30%, preferably 2 to 20% by weight. The actual addition amount should be determined based on the amount of chlorine generated during mixing with the chlorine-based detergent, that is, the type and amount of the mineral acid used, and the allowable generation amount.

Further, the surfactant which is the component (C) of the present invention is not particularly limited as long as it has sufficient detergency, and an anionic surfactant, a nonionic surfactant and further are necessary. Amphoteric surfactants can also be used depending on the case.
These surfactants may be used in combination of two or more, if necessary.

Of these, as the anionic surfactant, a usual sulfonate-based anionic surfactant or sulfate-based anionic surfactant is preferably used. As the sulfonate-based anionic surfactant,
Straight or branched chain alkyl (C ₈ ~C ₂₂₎ benzenesulfonate, long chain alkyl (C ₈ ~C ₂₂₎ sulfonate,
Long chain olefins (C ₈ ~C ₂₂₎ sulfonic acid salts, and the like. As the sulfate-containing anionic surfactant, a long chain monoalkyl (C ₈ -C ₂₂₎ sulfuric acid ester salts, polyoxyethylene (1-6 moles) long chain alkyl (C ₈ -C ₂₂₎ ether sulfate salts, polyoxyethylene (1-6 moles) alkyl (C ₈ -C ₂₂₎ phenyl ether sulfuric acid ester salts. As a cation which is a counter ion of these anionic surfactants,
Examples thereof include alkali metal ions such as sodium and potassium, alkanolamine ions such as monoethanolamine, diethanolamine and triethanolamine.

As the nonionic surfactant, polyoxyethylene (2-35 mol) long-chain alkyl (first
Grade or secondary C ₈ -C ₂₂₎ ethers, polyoxyethylene (2-35 moles) alkyl (C ₈ -C ₂₂₎ phenyl ether, polyoxyethylene polyoxypropylene block copolymers or the like are preferably used, further, amphoteric As the surfactant, betaine-type amphoteric surfactants such as alkylbetaine and alkylamidobetaine, and imidazoline-type amphoteric surfactants are preferably used.

Among the above-mentioned surfactants, particularly preferable ones are nonionic surfactants from the viewpoints of stability under acidic conditions, low foaming property, penetrating power, etc., and among them, biodegradable ones are particularly preferable. From the surface, it is a polyoxyethylene long-chain alkyl ether.

The above component (C) is blended in the toilet / tile cleaning composition in an amount of 0.1 to 20%, preferably 0.5 to 10%.

In the toilet / tile cleaning agent of the present invention, in addition to the above three components, if necessary, other components such as alcohols such as ethanol, glycol ethers such as ethylene glycol monoethyl ether, and the like. It is possible to add an organic solvent, a polysaccharide such as succinoglucan, a thickener such as a cellulose derivative such as cationized cellulose, a fragrance, a dye and the like.

Among them, the thickening agent increases the viscosity of the toilet / tile cleaning composition of the present invention by blending it with the thickening agent, for example, the contact time with the site to be cleaned becomes longer, so that the cleaning efficiency is further improved. Is increased, which is preferable.

[0020]

The chlorine scavenger which is the component (B) of the present invention,
It was found that the detergency is increased by blending with the mineral acid which is the component (A), as compared with the case where the mineral acid is used alone.
Further, by adding a surfactant as the component (C) thereto, the adhesion of the cleaning agent to the toilet bowl or tile was improved, and the cleaning effect was further enhanced.

In the above-described action of the present invention, the chlorine scavenger which is the component (B) has a chlorine scavenging effect and also has a property as a water-soluble solvent. Therefore, the organic components of dirt and the surfactant are dissolved. It is considered that this is because the detergency is improved and the detergency is increased by the interaction with the mineral acid as the component (A) and the surfactant as the component (C).
