Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a detergent composition for polluting drainage pipes, traps, etc., particularly for soiling mainly on oil components.

[Prior art and its problems]

In recent years, with the increase in the number of houses, various food wastes have been disposed inside the drainage pipes of kitchens, washrooms, bathrooms, toilets, etc., or inside the drainage pipes or traps of kitchens such as restaurants, restaurants, and hotels. Substances, dirt from oil components, organic waste from bathroom drainage, dirt from microorganisms and soap slag, insoluble matters of phosphates and carbonates, hair, or fibrous materials such as paper gradually adhere and accumulate. Frequent failures such as clogging, hindering smooth drainage, and producing a foul odor are occurring. Such dirt inside the drain pipe and trap may be due to the structure of the house,
It cannot be easily removed by brushing, etc., and it is not effective with general cleaning agents.

Heretofore, various cleaning agents for removing dirt such as drainage pipes and traps have been known and variously developed.

For example, (1) Cleaning agents mainly composed of strong alkali such as caustic soda are widely used for cleaning oil stains, but the solubility of the cleaning agent itself, the risk of bumping due to heat generation, or the temperature increase of plastic piping In the case of, there is a problem such as deformation.

(2) A method of adding strong alkali and aluminum powder is also known, but this is extremely dangerous due to the generated H ₂ gas.

(3) There is also known a method of making a clogged drainage pipe electrically conductive by using the injection pressure of aerosol, but it has almost no effect on dirt accumulated on the wall, and it is also effective against foul odors. There is no.

(4) Although it is possible to physically remove the drainage pipe to remove the dirt, it is time-consuming and not practical for a drainage pipe embedded in a wall.

(5) Various other foaming gases such as nascent oxygen or carbon dioxide, for example, heat treated sodium percarbonate (JP-A-52-103405)
No.), a method using sodium percarbonate and an activator (JP-A-52)
-152406), a method using an acid agent and an alkaline carbonate (JP-A-53-50207), and a method using an oxidizing agent such as an acid agent, an alkaline carbonate and sodium percarbonate (JP-A-53-50208). , A method using an alkaline agent and an inorganic peroxide and an auxiliary agent for decomposing the inorganic peroxide (JP-A-54-73806), a method using a heat-treated inorganic peroxide and a polyoxyethylene alkyl ether-based surfactant. (Japanese Patent Publication No. 57-61078), H ₂ O ₂
And various methods such as a method using a two-pack type cleaning agent composed of an alkali agent and a surfactant (Japanese Patent Publication No. 59-24799).

However, these conventional cleaning agents and cleaning agents have problems in terms of safety and corrosion, and are still insufficient in terms of cleaning effect. Under the present circumstances, there is a demand for the development of a more improved cleaning agent.

[Means for solving problems]

The present invention has been made in order to solve the above-mentioned problems of the prior art, and mainly in the kitchen equipment and baths, beauty salons, barbershops or dirty drainage pipes of buildings, especially oil components. It is an object of the present invention to provide a low-foaming detergent composition for a hard surface tube, which is capable of safely, easily and effectively cleaning the stains caused by the stain.

The drain pipe cleaning agent of the present invention is a cleaning agent composition comprising an inorganic peroxide and an acetylene glycol-based nonionic surfactant, wherein the inorganic peroxide is 50 to 99% by weight, and more preferably 55 to 65%. The nonionic surfactant 0.5 to 1
It is a composition containing 0.0%, and more preferably 1.0 to 5.0%.

Examples of the inorganic peroxide in the present invention include those that dissolve in water to generate hydrogen peroxide, such as sodium percarbonate, sodium perborate, and persulfates, and of these, sodium percarbonate is preferable.

Further, the acetylene glycol-based nonionic surfactant in the present invention is commercially available, and has the formula A solution of 2,4,7,9-tetramethyl-5-decyne-4,7-diol in water-soluble alcohol or glycol, or an ethylene oxide adduct of the above formula (I), represented by the following formula: That is In the formula (II), m + n = 3.5 to 30.

Of these, the above formula (I
Those shown in I) are preferred.

Next, a method of using the cleaning composition of the present invention or a cleaning mechanism will be described.

When the composition of the present invention deposits dirt into a dirty drain pipe, the inorganic peroxide, which is one of the active ingredients in the composition, dissolves in water in the pipe to cause nascent It is considered that oxygen is released, and due to its oxidizing action, etc., it acts on dirt adhering to the drainage pipe and cuts the bond, thereby effectively acting on the cleaning action.

Furthermore, the oxygen molecules of the gas generated in water have a low solubility in water, and thus rise as bubbles. It is speculated that this ascending action of bubbles gives a single physical force to the dirt adhering to the inner wall of the drainage pipe and is involved in the detachment of the dirt.

In the present invention, the surfactant has a function of assisting penetration and wetting of the active ingredient of the detergent into the stain, dispersing and emulsifying the removed stain, and further preventing the stain from reattaching to the surface to be washed.

The acetylene glycol nonionic surfactants represented by the above formulas (I) and (II) used in the present invention are extremely excellent in wettability as compared with the conventionally used surfactants, Since it has a remarkable permeability to dirt and has a defoaming effect, it has a feature that it suppresses abnormal foaming that occurs with a substance in dirt and also has an anticorrosive effect. Therefore, by using the acetylene glycol-based nonionic surfactant of the present invention in combination with an inorganic peroxide, an excellent effect not heretofore obtained is exhibited. In particular, a remarkable cleaning effect is recognized for stains mainly composed of oil components.

This is because the acetylene glycol-based nonionic surfactant of the present invention is extremely superior to conventional surfactants in terms of wetting, and therefore has good affinity with oil components and was deposited inside the drainage pipe. The cleaning agent penetrates thoroughly into the dirt, it takes a sufficient residence time, it slowly moves down the drain pipe, and the cleaning effect of the surfactant acetylene glycol itself is also added, so that an effective cleaning action is performed. It is considered to be a thing.

The drainage pipe cleaning composition of the present invention is essentially solid because it contains a solid inorganic peroxide as a main component, and can be used in the form of powder or tablet for easy use, and it is necessary. Depending on other components, for example, calcium carbonate, sodium carbonate, phosphates, silicates, pH adjusting agents such as Glauber's salt or alkali agents, extenders, further colorants, fragrances,
Additives that are usually added to detergents, such as chelating agents, can be added.

Further, a thickener such as polyethylene glycol or polypropylene glycol may be added to the detergent composition of the present invention to use it in a liquid state. By adding such a thickening agent, the residence time of the detergent component in the drainage pipe is increased, and a preferable washing effect can be obtained.

〔The invention's effect〕

The detergent composition of the present invention is deposited and adhered inside the drainage pipe or the trap due to the synergistic action of the unique properties of the acetylene glycol nonionic surfactant used in the present invention and the inorganic peroxide. It can penetrate into dirt, especially dirt containing a large amount of oil components, provides excellent cleaning effect, and does not cause backflow of abnormally foamed foam from the inlet, so it can be used safely on the human body and equipment. It can be done and is easy to handle.
