Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention does not leave a trace of wiping even if it is not wiped twice, and does not deteriorate the object to be cleaned. The present invention relates to a highly safe liquid cleaning agent.

[0002]

2. Description of the Related Art Cleaning is necessary to maintain aesthetics, but it is a laborious task. In particular, in recent years, the number of glossy surfaces such as glass and plastic has increased, and stains and cloudiness have become noticeable. Although the development of a technique for preventing stains using an antistatic agent or the like is being advanced, the effect is not sufficient at present and the number of cleanings is increased to cope with it.

For this reason, there is a demand for a cleaning method and a cleaning agent, which does not damage the object to be cleaned without requiring any effort, regardless of whether it is for home use or industrial use. Generally, the most convenient cleaning method is to spray the cleaning agent directly onto the object to be cleaned with a spray or a disperser and then wipe it off. However, this method is susceptible to "wiping residue" and is particularly noticeable on glossy plastic or glass surfaces. In order to remove this "wiping residue", it is often the case that the wiping is performed twice, such as an empty wiping or a water wiping, but as a result, it takes nearly double the time and is not preferable.

Further, it is not uncommon for these detergents to deteriorate the painted surface and the plastic surface, cause white turbidity, stains, cracks, and other damage, and impair the appearance. Tokkyo 5-7
Japanese Patent No. 015 describes a substrate impregnated with a cleaning agent as a cleaning article. Although the present invention is considered to be one of the solutions, it is bulky because the substrate contains a cleaning agent, and is expensive and uncommon compared to a disperser type cleaning agent. In addition, the cleaning agent used has insufficient antibacterial properties, and on the other hand, the addition of the antibacterial agent significantly impairs the "no wiping residue", which is the merit of the above patent, and significantly lowers its commercial value. I knew that.

Japanese Unexamined Patent Publication (Kokai) No. 64-9299 describes a liquid cleaning agent which is excellent in cleaning power against oil stains and the like. Although the present invention considers "wiping residue", an alkaline agent is contained as a constituent component and deteriorates or damages some materials such as polycarbonate. Also, it is dangerous if it adheres to the skin. Japanese Patent Publication No. 26670/1990 describes a foamable liquid cleaning product. Although the present invention is a combination of an anionic surfactant and glycol monobutyl ether, the content of non-volatile components is large and "wiping residue" is remarkable.

As described above, many of these conventional cleaning agents pay great attention to the cleaning power and the like, but due to the alkaline agent and the high-concentration surfactant added for that purpose, "wiping residue" is left. We are not paying much attention to the effects on the wash items.

[0007]

DISCLOSURE OF THE INVENTION The present invention provides a liquid detergent composition for wiping a hard surface, which is good and stable, which does not leave a trace of wiping while ensuring a good detergency and does not deteriorate the object to be washed. Is provided. These requirements are generally contradictory, and it has been difficult for the prior art to satisfy all of them.

[0008]

In order to suppress the generation of unwiping residue, it is necessary to select a surfactant and extremely reduce the amount of non-volatile components. However, if the blending amount of the surfactant is reduced, the antibacterial property of the detergent is lowered.

As a result of intensive studies to solve the above-mentioned problems of the prior art, the present inventors have found that a water-miscible solvent and a specific antibacterial agent, which were conventionally treated as a detergency enhancer, were used. They found that the combination has a synergistic effect of antibacterial properties, solved one of the conventional problems, and conducted further studies to complete the present invention. That is, the liquid cleaning composition for hard surface cleaning of the present invention is characterized by containing the following components (a), (b) and (c).

(A) Anionic surfactant and / or amphoteric surfactant: 0.005 to 1% by weight. (B) One or more water-miscible solvents: 3% by weight or more. (C) 5-chloro-2-methyl-4-isothiazoline-
From 3-one, 2-methyl-4-isothiazolin-3-one, 2-bromo-2-nitro-1,3-propanediol and 1,2-benzisocyazolin-3-one and formaldehyde donor type antibacterial agent 1 chosen
One or more antibacterial agents: 0.0001 to 1.0% by weight.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION As the surfactant as the component (a),
Anionic surfactants and / or amphoteric surfactants are used. According to the studies by the present inventors, cationic surfactants such as quaternary ammonium salts have lower detergency than other surfactants, while nonionic surfactants such as polyoxyethylene alkyl ethers Even a relatively small amount can be wiped off, but it is easily noticeable. However, cationic and nonionic surfactants can also be used as long as the effects of the present invention are not impaired.

The anionic surfactant as the component (a) is not particularly limited. Any of the general hydrophilic anionic surfactants such as carboxylic acid salts, sulfuric acid ester salts, sulfonic acid salts, amino acid type anion salts and phosphoric acid ester salts can be used. Carboxylates have about 8 to 24 carbon atoms obtained from vegetable oils (palm oil, palm oil, soybean oil, rapeseed oil, castor oil, various hardened oils, etc.) and animal oils (beef tallow, lard, fish oil, etc.). Soaps composed of resin acids obtained from fatty acids, rosins, tall oils, etc., petrochemically synthesized fatty acids, and their derivatives (for example, ethylene oxide adducts, propylene oxide adducts, etc.) are applicable. Typical examples are sodium oleate, potassium stearate, sodium laurate and the like.

The sulfate ester salt has 8 to 18 carbon atoms.
A higher alcohol sulfuric acid ester salt having a linear or branched alkyl or alkenyl group or an alkylbenzene group, a sulfated oil, a sulfated fatty acid ester, a sulfated olefin or a higher alkyl ether sulfate salt (addition of ethylene oxide 1 to 7), etc. Both are applicable and can be used. Examples include polyoxyethylene (P = 3: number of added molecules) sodium lauryl ether sulfate, polyoxyethylene (P = 5) potassium stearyl ether sulfate, and the like.

Examples of the sulfonate include alkylbenzene sulfonate having a linear or branched alkyl or alkenyl group having 8 to 18 carbon atoms, alkylnaphthalene sulfonate and paraffin sulfonate, and any of them can be used. . Examples include sodium lauryl benzene sulfonate, potassium capryl naphthalene sulfonate,
Examples include potassium cetyl sulfonate, sodium α-olefin sulfonate, and the like.

The amino acid type anion salt is an amino acid derivative having a property as an anion, and includes sodium lauroyl sarcosine, sodium lauroyl methylalanine, and N-.
Myristoylmethyl taurine sodium and the like can be used in the present invention. The phosphate ester type anion includes a monoester salt type and a diester salt type, but the diester salt type generally has low water solubility, and in the present invention, the monoester salt type is mainly possible.

Although various cations correspond to the anionic surfactant used in the present invention, sodium,
Alkali metal ions such as potassium, ammonium ions, organic amines such as alkanolamines (monoethanolamine, triethanolamine, etc.) are particularly desirable.

The amphoteric surfactant used in the present invention is not particularly limited. There are several types of amphoteric surfactants such as sulfate ester type, sulfonic acid type, and phosphate ester type when classified by anion part, but the most common are carboxylate type amino acid type and betaine type amphoteric surfactants. Target.

The amino acid type amphoteric surfactant has an amine salt type cation portion, and sodium laurylaminopropionate or the like can be used. The betaine salt-type amphoteric surfactant has a quaternary ammonium salt-type cation portion, and has lauryl dimethyl betaine, stearyl dimethyl betaine,
Lauryl dihydroxyethyl dimethyl betaine, coconut oil fatty acid amide propyl dimethyl betaine, lauric acid amide propyl dimethyl betaine and the like can be used. These anionic surfactants and amphoteric surfactants are used alone or in combination of two or more.

The component (a) surfactant is incorporated in the liquid detergent composition of the present invention in an amount of 0.005 to 1% by weight, preferably 0.005 to 0.2% by weight. If the blending amount is less than 0.005% by weight, the cleaning agent does not adapt to the surface and dirt of the object to be washed, and sufficient cleaning power cannot be obtained, and an increase in wiping residue may occur. On the other hand, if it exceeds 1% by weight, unwiping residue occurs.

Examples of the water-miscible solvent as the component (b) include methanol, ethanol, propanol, isopropanol, ethylene glycol, propylene glycol, glycerin, monohydric or polyhydric alcohols having 4 or more carbon atoms or their derivatives such as methyl. Cellosolve, ethyl cellosolve, methyl carbitol, butyl carbitol and the like are used, but ethanol and isopropanol are particularly useful.

The water-miscible solvent used in the present invention is effective from about 3% by weight for the purpose of improving the detergency and preventing volatility by increasing the volatility to prevent unwiping residue.
It increases when the content is 5% by weight or more, and the effect is further exhibited when the content is 10% by weight or more. Further, generally, the larger the blending amount is, the higher the effect is, but the deterioration of the object to be washed is rapidly increased, and the risk of odor, ignition, etc. is also increased. There are various ways of thinking about the upper limit of the blending amount, but if it exceeds 20% by weight, these defects become remarkable and the usability deteriorates. Therefore, the water-miscible solvent of the component (b) is blended in the liquid detergent composition of the present invention in an amount of 3% by weight or more, preferably 3 to
20% by weight, more preferably 5 to 20% by weight, still more preferably 10 to 20% by weight.

As the antibacterial agent as the component (c), 5-chloro-2-methyl-4-isothiazoline, 2-methyl-
4-isothiazolin-3-one, 2-bromo-2-nitro-1,3-propanediol, 1,2-benzisosiazolin-3-one and salts thereof are used alone or in combination of two or more. . The antibacterial agent composition containing the antibacterial agent as the main component is the product name "Caison CG" (manufactured by Rohm and Hase), and the antibacterial agent composition containing the antibacterial agent as the main product is the trade name. An antibacterial agent composition containing the antibacterial agent as "Bronopol" (manufactured by Boots) is a trade name "Proxel XL-2".
(Manufactured by ICI).

Further, formaldehyde donor (For)
Maldehyde Donor type antibacterial agents include
For example, N, N′-methylenebis [N ′-{1- (hydroxymethyl) -2,5-dioxo-4-imidazolidinyl} urea] (Lmidazoliding We
a: trade name Fermalll 115, manufactured by Sutton), cis-1- (3-chloroallyl) -3,5,7-
Triazo-Azonia Adamantine Chloride) (Qua
ternium-15: trade name Dowicil 20
0, manufactured by Dow) and dimethylol dimethyl hydantoin (trade name: Fly).
dant, manufactured by Lonza) and the like can be used.

The component (c) antibacterial agent is blended in the liquid detergent composition of the present invention in an amount of 0.0001 to 1.0% by weight, preferably 0.0002 to 0.3% by weight. When the content is less than 0.0001% by weight, sufficient antibacterial property cannot be obtained, while when it exceeds 1% by weight, unwiping residue occurs.

Further, the compounding amount of the antibacterial agent as the component (c) is 0.
By controlling the amount to be not more than 02% by weight and the amount of the water-miscible solvent such as ethanol (b) component added to be not less than 10% by weight, it is possible to obtain a sufficiently smooth and glossy surface such as a window glass or an acrylic plate. It has the ability to prevent unwiping residue and also exhibits strong antibacterial properties. It is considered that this is because the range of effective microorganisms could complement each other.

Further, although depending on the condition of the article to be washed, it is generally desirable that the amount of the non-volatile components such as the surfactant and the antibacterial agent used in the present invention be small. Particularly, on a smooth and highly glossy surface such as a window glass or a transparent acrylic plate, when the non-volatile component exceeds 0.2% by weight, the wiping residue becomes conspicuous. In addition, even if the surface of the coated iron plate or the wall material has more irregularities, where the uncleaned residue is relatively unnoticeable, if it exceeds 1% by weight, the uncleaned material may be left over or the material to be washed may be adversely affected. Additional work is required.

It is a fact that the addition of an alkaline agent improves the detergency of oil and fat stains. However, the alkaline agent deteriorates polycarbonate and other materials, and
Direct contact with skin is dangerous and not desirable as a daily cleanser. On the other hand, the areas where strong oil stains are attached are extremely limited, such as the range where an alkaline agent is indispensable and around a ventilation fan, and stains at other general locations can be sufficiently wiped without the alkaline agent. Therefore, it is desirable that the liquid detergent of the present invention contains substantially no alkaline agent.

The pH of the liquid detergent composition of the present invention is preferably 9 or less, and more preferably adjusted to near neutral. If the pH exceeds 9, the antibacterial agent of the present invention may become unstable, which is not preferable.

In the present invention, general components can be blended according to the object to be washed unless the object is defeated, and the balance is 100% by weight with water. The water used is not particularly limited and may be tap water, but purified water such as ion-exchanged water or distilled water is more preferable. Further, the cleaning agent of the present invention is not particularly limited in its usage, but in general, it is sprayed directly on the object to be washed and then wiped with a suitable material such as a waste cloth, or Wipe the items to be washed with a soaked detergent. At this time, in principle, it is not necessary to wipe twice.
