Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to cleaning and removing dirt generated in drain pipes, traps, filter pipes, etc., and extermination of force generated in bathrooms, kitchens, etc. More specifically, the present invention relates to a cleaning agent that can retain at a target location due to its high viscosity and can effectively exert the strong sterilizing and cleaning power of hypochlorite in particular.

[Conventional technology and its problems]

In recent years, with the Westernization of general housing and the emergence of high-rise apartment buildings, mold has grown in kitchens, bathrooms, toilets, washrooms, etc., and food waste, excrement, and hair have grown in these drain pipes, traps, and overflow pipes. There are many cases where the phenomenon of clogging due to accumulation of etc. occurs. In order to deal with this phenomenon, various physical and chemical cleaning agents have been developed. and a method of decomposing dirt with microorganisms (Japanese Patent Publication No. 38-26465), a method using soda percarbonate and an activator (Japanese Patent Publication No. 52-15240)
6) and the method using an acid agent and an alkaline carbonate (Japanese Patent Application Laid-Open No. 53-50208), the cleaning power is still insufficient. A method in which a mixture of the above is poured into a drain pipe, dissolved in water, and the generated heat and hydrogen gas dissolves the dirt (US Patent No. 347140)
No. 7-), methods using strong acids such as sulfuric acid, nitric acid, orthophosphoric acid or sulfamic acid (US Pat. No. 3,538,008), etc. are recommended for storage and use.

It is dangerous and there is a risk of corrosion. In addition, conventional cleaning agents containing alkali metal hypochlorite, alkaline substances, and surfactants are relatively safe and have excellent cleaning power, and are also effective in removing bad odors. Although it is effective, its viscosity is extremely low, so when used on sloped or vertical surfaces, the time it remains in the target area is short and the cleaning effect cannot be fully demonstrated. there were.

In addition, water-soluble polymer compounds such as polyvinyl alcohol, methylcellulose, polyacrylate, and xanthan gum are commonly used as thickeners, but these thickeners are especially added to detergents containing hypochlorite. In such cases, the thickening agent degenerates and decomposes, making it impossible to obtain a thickening effect.

[Purpose of the invention]

The purpose of the present invention is to eliminate the various drawbacks of the above-mentioned conventional examples, to have excellent cleaning, deodorizing, and sterilizing effects, and to remain in the target area for a long time to fully exert the cleaning, deodorizing, and sterilizing effects. An object of the present invention is to provide a cleaning agent having a viscosity that can reduce the amount of water.

[Means for solving problems]

In order to achieve the above object, the present invention employs the following configuration for the cleaning agent. That is, hypochlorite, an alkaline substance, 0.1 to 5.0% by weight of fatty acid alkali metal salt, 0.1 to 10.0% by weight of aliphatic amine oxide, and 0.01 to 5.0% by weight of aliphatic amine oxide. This is a sterilizing viscous cleaning agent characterized in that it contains ~1.0% by weight of alkali metal salt of alkanesulfonic acid as an essential component and is prepared as a viscous liquid.

In the sterilizing viscous cleaning agent according to the present invention, examples of the hypochlorite component include sodium, potassium, lithium, calcium, or magnesium salts of hypochlorous acid. , alkaline substances include sodium hydroxide, potassium hydroxide, etc., and fatty acid alkali metal salts may be selected from fatty acid sodium, fatty acid potassium, and other fatty acid alkali metal salts; For example, saturated fatty acids such as lauric acid, myristic acid, 0)rutimic acid, and stearic acid can be used. In addition, examples of aliphatic amine oxide include bishydroxyethylalkylamine oxide,
The alkyl group may be selected from dimethylalkylamine oxide and cyclic alkylamine oxide, and the alkyl group is preferably a group such as coconut alkyl, lauryl, myristyl, tallow alkyl, stearyl, etc. Examples of the alkanesulfonic acid alkali metal salts include sodium or potassium salts of alkanesulfonic acids having an average carbon number of 10 to 18.

A viscous liquid preparation is prepared by dissolving each of these essential components in deionized water or the like.

[For production]

The cleaning agent with this structure has excellent cleaning power and
10 to 500 Q, which can be retained for a long time on an inclined or vertical wall surface.

It exhibits a viscosity of P. Specifically, hypochlorite is preferably blended in a proportion of 0.1 to 12% by weight, and exhibits decomposition, deodorization, and sterilization effects on mold and grime due to its strong oxidizing action. The alkaline substance is preferably blended in a proportion of 1 to 5% by weight, especially fat, vegetable waste, tea leaves, etc.
It is effective in removing dirt such as hair. In addition, fatty acid alkali metal salts, aliphatic amine oxides, and alkane sulfonic acid alkali metal salts are all substances that have been commonly added to hypochlorite aqueous solutions as surfactants, but each has a fatty acid alkali metal salt as an essential component. Salt is 0.1-5.
0% by weight, 1-10.0% by weight of aliphatic amine oxide and 0.01% by weight of alkali metal alkanesulfonate.
When blended at a ratio of ~1.0% by weight, the detergent has a cleaning effect based on its surface activity and a
It exhibits a thickening effect that produces a viscosity of 0 c, p. Note that if the fatty acid alkali metal salt, aliphatic amine oxide, and alkanesulfonic acid alkali metal salt are not blended in the proportions within the above-mentioned ranges, not only will the necessary viscosity not be obtained, but also phase separation will occur in the cleaning agent components. .

Furthermore, optional components such as colorants and fragrances can be added to the cleaning agent of the present invention within a range that does not affect the decomposition of hypochlorite.

〔Example〕

Next, the present invention will be explained in detail.

Table 1 In Example 1, the Φ germicidal viscous cleaning agent is prepared with the components and blending amounts shown in Table 1 above. Specifically, first, myristic acid is added to a predetermined amount of water. Adding and uniformly dissolving potash, sodium alkanesulfonate and coconut dimethylamine oxide, and hydrating this solution) I
It is prepared by adding Jum and an aqueous sodium hypochlorite solution and mixing them uniformly. This prepared liquid is transparent and has a viscosity of 42c, p (B-type rotational viscometer rotor/FL
It was a persimmon aqueous solution of 1.6 Q r, p, m, at, 25°C), and the effective chlorine reduction rate was 8% (left in a thermostat at 35°C for one month).

Gradually pour 100 cC of the cleaning agent in Example 1 around the drain of a stainless steel kitchen sink (contained inside the garbage basket) contaminated with food waste, leave it for 10 minutes, then rinse thoroughly and remove the garbage. When we observed the dirt in the basket and drain, we found that
It was confirmed that the dirt was almost completely removed and the bad odor also disappeared.

Next, the cleaning agent of this example was applied to the mold that had formed on the joints of the tiles in the bathroom at a ratio of 15/I, left to stand for 10 minutes, and then rinsed off with sufficient water. As a result, it was confirmed that the mold had been almost completely removed.

Next, other Examples A, B, which were prepared with different constituent components or different blending ratios by the same process as in Example 1,
C, and D are shown in Table 2 below. Moreover, E, F, G, and H were each prepared as comparative products. In Table 2, ◯ indicates good properties, △ indicates properties that are possible albeit to a low degree, × indicates properties that are impossible, and "separation" (ne phase separation state).

Table 2 From Table 2, it can be seen that the products of the present invention in Examples A to D all have a relatively high viscosity, and are due to the surface active components potassium myristate, lauryl dimethylamine oxide, and sodium alkanesulfonate. The increasing effect can be confirmed, and the rate of reduction in available chlorine is not affected much by the amount of each surfactant component and is stable.

Another comparison item! i! , F, G and H, when the surfactant component is blended in a single or uneven amount,
Indicates that no phase separation occurs or thickening occurs.

Furthermore, by comparing the properties of Examples A, B, C, and D, it can be seen that the increase in the amount of hypochlorite has little effect on the thickening effect of the liquid agent. [Effects of the Invention] As mentioned above, The ``sterilizing viscous cleaning agent'' according to the present invention is
It is safe to handle and store, stably has a strong cleaning effect, and exhibits a viscosity that allows it to remain in the area to be cleaned for a long time, so that the above-mentioned cleaning effect can be maximized.
