Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a two-part foaming product that can effectively remove stains from hard surfaces such as plastics, ceramics, tiles, joints, and the inside of drain pipes, as well as provide long-term deodorizing effects. The present invention relates to a hard surface cleaning composition.

Traditionally, household detergents for plastics, ceramics, and tiles have been known as liquid detergents containing acids or alkalis as their main ingredients, and as detergents for joints, powdered or liquid detergents containing abrasives have been used. Are known. However, all of these detergents still had insufficient cleaning power.

In recent years, with the emergence of Western-style general housing or high-rise apartment complexes and the Westernization of eating habits, food waste,
Clogged with excrement, hair, mud, bathroom grime, etc.
There are many cases where water adheres to the inner wall of the pipe and obstructs the flow of water inside the pipe. Such stains inside drain pipes are one of the most difficult to remove among household hard surface stains, partly because the dirty parts are difficult to reach.

Conventionally, the method of removing stains from drain pipes, traps, lacrimal ducts, etc. is to dissolve them using chlorinated hydrocarbons and activators.
Emulsifying method (US Pat. No. 3,553,145),
Method of decomposing dirt using enzymes and microorganisms
26465), 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),
Methods using oxidizing agents such as acid agents, alkaline carbonates, and sodium percarbonate have been reported (Japanese Unexamined Patent Application Publication No. 53-50208), but the cleaning power of these methods is still insufficient.

US Pat. No. 3,471,407 reports a method of introducing strong alkalis such as caustic soda, aluminum and inorganic nitrates, but this is extremely dangerous. Also, US Patent Specification Tube 3538008-+3
In the specification, )(2S 04 , HC-e, HN 0
2. A method of adding silica sol and a strong acid such as orthophosphoric acid or sulfamic acid has been disclosed, but this method is also extremely dangerous and highly corrosive.

On the other hand, it is also known to use aerosol injection pressure to open a completely clogged drain pipe, but this method has little effect on dirt deposited on the walls. It is possible to physically clean the inside of the drain pipe, but this is time-consuming and difficult to do easily at home.

The present invention has been made to solve the problems of the prior art as described above, and can easily and effectively remove stains from hard surfaces such as plastics, ceramics, tiles, joints, bathtubs, and the inside of drain pipes. It is an object of the present invention to provide a two-component foaming hard surface cleaning composition that can remove odor and provide a long-term deodorizing effect. Another object of the present invention is to provide a cleaning composition that is stable and safe to use both during storage and use.

That is, the two-part foaming hard surface cleaning composition of the present invention has the following parts A and B, and also contains part A and/or part B.
Alternatively, agent B contains a cationic surfactant. Part A and Part B are brought into contact or mixed during use,
Distilled water is added if necessary.

(1) Agent A: A solid composition containing a hydride compound.

(21B agent: acid agent composition containing an acid.

Agent A is a composition containing a hydride compound, and its shape is preferably powdery or granular in terms of handling.

The content of the hydride compound in agent A is preferably 50 to 100 wt%, more preferably 70 to 95 wt%. If this amount is less than 50%, the foaming and heat generation effects will be poor, and it will not necessarily be possible to obtain excellent detergency. Specific examples of the hydride compound include sodium borohydride, lithium aluminum hydride, etc. Among these, sodium borohydride is particularly preferred.

Part B contains an acid, and specific examples of the acid include sulfuric acid, hydrochloric acid, nitric acid, orthophosphoric acid, and sulfamino acid.

At least one of Part A and Part B contains a cationic surfactant in an amount of 0.1 to 20% by weight, preferably 1 to 10% by weight. Provides deodorizing effect.

Specific examples of cationic surfactants include C8-5-C18 monoalkyltrimethylammonium, Part J, 06
~C18 dialkyldimethylammonium resistant, 06~C
Particularly preferred are I6 alkyldimethylbenzylammoniunzylammonium salts.

If the amount of the cationic surfactant is less than 0.1% by weight, it will not provide a long-lasting deodorizing effect;
If it is less than this, the stability during storage will deteriorate, which is not preferable.

The B agent may be either liquid or solid, and a particularly preferable combination is a system in which 1 to 10 weight percent of a cationic surfactant is blended into the following A agent and/or B agent.

(1) Powder/liquid type A agent: Powder composition containing 50 to 100 wt% sodium borohydride.

Agent B: 2-100 vt% sulfuric acid (aqueous solution).

(2) Powder/powder type Agent A: 50 to 100 wt% sodium 6- Powder composition containing robihydride.

Agent B: Powder composition containing 2 to 100 wt% of sulfamic acid.

In addition, (a) a hydride compound contained in agent A;
The molar ratio of (b) acid contained in agent B to (a) in terms of weight ratio
/(bl= is preferably in the range of 150/1 to 1/2, more preferably 130/] to]/1.

If this value exceeds 150/1, the synergistic effect with component (b) will decrease, and sufficient cleaning power will not necessarily be obtained. , the heat generation decreases, making it impossible to obtain sufficient cleaning power.

Next, a method for using the hard surface cleaning composition of the present invention and a cleaning mechanism will be explained.

Parts A and B are stored separately and each is applied separately onto the hard surface soil at the time of use.

The order of application may be either first or simultaneously. In the case of a mixture of powder/liquid, it is more practical to first sprinkle the powder (former A) and then pour the liquid (former B).

Then add the desired amount of water.

Hydride compounds are only slowly soluble in water and have detergency, but when they come into contact with acid they decompose with significant foaming and heat generation. Therefore, when Agent A and Agent B come into contact with each other on a hard surface stain, an improvement in the stain removal effect due to the acid and the removal effect due to physical force due to the large amount of foam generated can be obtained. Therefore, it can be effectively removed even in hard-to-reach places, and even on the outer surface, it can be removed without scrubbing or the like. Further, due to the generation of air bubbles, the cleaning agent can be spread even to places where the cleaning agent is difficult to reach, such as recesses, due to the filling power of the air bubbles, and cleaning can be performed efficiently. In addition, foaming prevents the cleaning agent from adhering to the cleaning agent and allows it to remain on inclined and vertical surfaces for a sufficient period of time required for cleaning.

Furthermore, the adhesion of dirt can be reduced due to the significant heat of reaction between the A and B agents.

As described above, in the cleaning composition of the present invention, (1) cleaning power due to acid and decomposition of hydride compounds, (2) physical external force on dirt due to foaming, filling of cleaning agent, and cleaning agent Adhesion or stagnation, and (3) significant heat of reaction work synergistically to provide superior cleaning power unimaginable with conventional cleaning agents.

It is very common for the hard surfaces to be cleaned to have slopes and to have eruptions such as recesses and corners that are difficult to clean. Therefore, foaming strength and foam stability are important factors. For example, consider the drain pipe of a household sink.

This drain pipe descends almost straight, and many have a bellows structure on the side wall. A predetermined flow channel is formed in the pipe, and when water is allowed to flow, the water flows uniformly within the pipe and flows quickly along the flow channel.

Even if a cleaning agent is poured into such a drain pipe, the cleaning agent only comes into contact with a specific part and quickly flows down, making it impossible to effectively clean the area. 9- JP-A No. 52-152406 and No. 53-5, which were already introduced
Powdered foaming compositions have also been reported in Publication No. 0207 and No. 53-50208, but these have insufficient foaming amount and foaming power, and when applied to the above-mentioned drain pipe, foaming compositions are insufficient. It flows down quickly.

On the other hand, when using agent A and agent B of the present invention,
It generates a lot of heat, and at the same time has a strong foaming amount and foaming power, filling the entire inside of the drain pipe and exerting physical force on the dirt, and furthermore, it slowly descends inside the drain pipe. Contact with dirt for a sufficient period of time.

Furthermore, in the hard surface cleaning agent of the present invention, the cationic surfactant blended as the third component not only stabilizes the bubbles generated, but also adsorbs dirt inside drain pipes and hard surfaces such as internal surfaces, removing dirt. In addition to preventing the adhesion of dirt, its sterilizing effect suppresses the activity of microorganisms that generate dirt and bad odors, and can also have an odor-preventing effect.

As is clear from the above explanation, the 10-2-component foaming cleaning composition of the present invention is effective on all hard surfaces, and is effective on areas where the cleaning agent easily flows, such as inclined surfaces and vertical surfaces, and It is particularly effective for areas that are difficult to clean, such as recesses, corners, and inside pipes, and can effectively clean drain pipes, which are the most difficult to clean in general households.

The cleaning composition of the present invention further includes a nonionic surfactant, Glauber's salt, soda carbonate,
Salt, sodium triphosphate, sodium diphosphate, tripolyphosphate, fillers such as pylocaliphosphate, colorants, fragrances, bactericides, chelating agents, activators, alkaline agents,
Alternatively, additives commonly added to other cleaning agents can be added. These additives are preferably added in such a way that they do not impair the stability or function of Part A and Part B. For example, it is preferable to add a chelating agent or an activator to Part A.

Incidentally, by solubilizing and blending the fragrance among the above-mentioned additives, the fragrance and deodorizing effect can be further enhanced.

The nonionic surfactant also contributes to the stability of the foam generating liquid and the foam produced. Specific examples include: These are 0.1 in Part A and/or Part B.
It is generally added in an amount of up to 20% by weight, preferably 0.5 to 10% by weight.
