Description

Detailed Description of the Invention The present invention is a two-part foaming product that can effectively remove dirt from hard surfaces such as plastics, ceramics, tiles, joints, and the inside of drain pipes, as well as provide deodorizing and 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, excrement, hair, and dirt are being deposited inside drain pipes, traps, and filtration pipes in kitchens, bathrooms, and toilets. The flow of water inside the pipes is often obstructed due to bathroom dirt and grime becoming clogged or adhering to the inner walls of the pipes. Such dirt inside drain pipes is one of the most difficult to remove among hard surface dirt in private gardens, partly because it is difficult to reach the dirty parts.

Traditionally, the method of removing dirt from drain pipes, traps, filter pipes, etc. is to dissolve it using chlorinated hydrocarbons and activators.
Emulsification method (U.S. Patent No. 3,553,143), method of decomposing dirt using enzymes and microorganisms (Japanese Patent Publication No. 3
8-264'65), 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), acid agent, alkaline Methods using oxidizing agents such as carbonates and sonida percarbonate have been reported (Japanese Unexamined Patent Publication No. 53-50208), but none of these methods have sufficient cleaning power.

US Pat. No. 3,471,407 reports a method of adding strong alkalis such as caustic soda, aluminum, and inorganic nitrates, but this is extremely dangerous. Also, U.S. Patent Specification Letter No. 3,538,
In the specification of No. 008, H2SO4゜1 (CI, H
A method has been disclosed in which a strong acid such as orthophosphoric acid or sulfamino acid and silica sol are added, but this method is also extremely dangerous and highly corrosive.

On the other hand, it is also known to use aerosol injection pressure to divert a completely clogged drain pipe, but this method is hardly effective against dirt that has accumulated on 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 odors and provide deodorizing and deodorizing effects. 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 the part B contains 0.1 to 50% by weight of silicate. It is characterized by

(1) Agent A: Contains an inorganic peroxide and has an effective oxygen amount of 0.
25-25% oxygen-based oxidizer composition or an aqueous solution of this composition.

(2) Agent B: Contains hypochlorite and has an effective chlorine amount of 0.2

Part A and Part B are brought into contact or mixed during use, and water is added if necessary.

The present invention will be explained in more detail below.

Part A is an oxygen-based oxide composition containing an inorganic peroxide or its aqueous solution, and the concentration of inorganic peroxide in Part A is 0.5 to 50% diluted in the case of a liquid, and 10% in the case of a solid. ~ioo wt%, more preferably 1~35wt%> and 30~90wt%, respectively. The amount of effective oxygen in agent A is 0.25 to 25%, preferably 0.5 to 20%. If the amount of effective oxygen is less than 0.25%, sufficient cleaning power cannot be obtained, while if it exceeds 25%, the storage stability deteriorates and it is also dangerous to handle in a vacuum, which is not preferable.

Here, the effective oxygen amount refers to the oxygen contained in Agent A that is effective for bleaching, etc. Ratio of (0) to the entire A agent (wt%)

If it is less than 5 inches, sufficient cleaning power will not be obtained, and on the other hand, if it is less than 25
If the temperature exceeds 1, the storage stability will be significantly deteriorated, and it will also be dangerous to handle at home, which is not preferable.

Here, the effective chlorine amount is the ratio of gi isobaric effective chlorine i (ctm) contained in the B agent to the entire B agent.

Examples of the hypochlorite of agent B include sodium hypochlorite, potassium hypochlorite, and high-grade saran powder, with sodium or potassium hypochlorite being particularly preferred.

Furthermore, the B agent contains 0.1 to 50% by weight of silicate, preferably 0.5 to 50% by weight. This amount is 0.1w
If it is less than 50 wt, sufficient deodorizing and deodorizing effects cannot be obtained, and if it exceeds 50 wt, the stability of the active ingredient of agent B will be adversely affected.

However, if the B agent is a liquid composition, add 0.5 to 5 w of silicate.
It is suitable to contain t%, and in the case of a solid composition, it is suitable to contain 0.5 to 50wt%.

Silicates are added to Part B because adding silicates to Part A has a negative effect on the stability of the inorganic peroxide.

In the foaming cleaning composition of the present invention, a surfactant may be further added to either or both of the A and B agents. The surfactant □ agent mainly contributes to the stability of foaming, as will be explained in detail later. Therefore, any material having such an effect can be used, and it is preferable to use a material that can be stably stored together with the A component or the B component. As the surfactant, any of anionic surfactants, nonionic surfactants, cationic surfactants, and amphoteric surfactants can be used, but particularly preferred are anionic surfactants and nonionic surfactants. It is an ionic surfactant. Specific examples of such surfactants include the following.

If it exceeds 20%, the stability during storage will deteriorate significantly, and the cleaning effect will decrease due to a decrease in the amount of active ingredients. Come.

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.

Application 111 (It doesn't matter which order comes first, or it can be done at the same time. For air/powder type and powder/liquid type stations, it is better to spray the powder first and then pour the liquid. Practical. Also, with powder/powder type, add appropriate amount of water after spraying both.Liquid/°liquid type is easy to handle and can be applied to any hard surface, especially by hand. It is convenient to apply to hard surfaces such as '4%F>'T and furrow surfaces that are hard to reach.From this point of view, hydrogen peroxide and sodium hypochlorite are advantageous because they can be stored stably even in liquid form. .

When Part A and Part B come into contact and react on a hard surface or dirt,
Dirt is decomposed by the oxidizing power of the generated oxygen.

Oxygen is generated by both the decomposition of inorganic peroxide and the decomposition of hypochlorite, and acts synergistically to decompose dirt and carbon. 49K.

Since chlorate has a strong bactericidal effect, it also works as a bactericidal agent, especially as a fungicide.

Further, the large amount of bubbles generated by the reaction removes dirt by physical force. 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. Furthermore, due to the generation of air bubbles, the filling power of the air bubbles allows the cleaning agent to spread even in areas where it is difficult for the cleaning agent to reach, such as recesses.
Cleaning can be performed efficiently. In addition, foaming makes it easier for the cleaning agent to adhere to hard surfaces, allowing it to remain on inclined and vertical surfaces for a sufficient period of time necessary for cleaning.

Furthermore, the adhesion of dirt can be reduced by the heat of reaction between Agent A and Agent B.

As described above, in the cleaning composition of the present invention, peroxide and hypochlorite are decomposed.

(1) Oxidizing power and sterilizing power (2) Physical external force on dirt due to foaming, filling of cleaning agent, and adhesion or stagnation of cleaning agent (3) Reaction heat works synergistically, making conventional cleaning You can get superior cleaning power that you couldn't imagine with detergents.

In addition, the pH buffering effect of the silicate contained in Agent B prevents the growth of putrefactive bacteria, and the formation of a surface adsorption film prevents the generation of bad odors, making it particularly effective for preventing drainage pipe stains and gutter odors in traps. It is able to maintain superior effects, and exhibits deodorizing and deodorizing effects that have never been seen before.

It is very common for the hard surfaces to be cleaned to have slopes or surfaces that are difficult to clean, such as recesses or corners. Therefore, foaming power or foam stability is an important factor. For example, consider the drain pipe for a garden sink. This drain pipe descends almost straight, and many have a bellows structure on the side wall. A predetermined flow channel is formed within the pipe, and when water is allowed to flow, the water does not flow uniformly within the pipe, but flows 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 clean efficiently. [Special Features Already Shown] 11 Publications No. 152406/1980, No. 53/502
Powdered foaming compositions have been reported in Publication No. 07 and Publication No. 53-50208, but these have insufficient foaming amount and foaming power, and when applied to writing drain pipes. It flows down quickly while foaming.

On the other hand, when using agent A and agent B of the present invention,
It has a strong foaming amount and foaming power, and it fills the entire inside of the drain pipe and applies physical force to the dirt.Moreover, it slowly descends inside the drain pipe and stays away from the dirt for a sufficient period of time. Contact.

In particular, when at least one of the A agent and the B agent contains a surfactant, the foaming power increases and the generated bubbles become stable, further enhancing the foaming effect described above.

As is clear from the above explanation, the two-component foaming cleaning composition of the present invention is effective on all hard surfaces, and is suitable for cleaning moldy surfaces, sloped surfaces, vertical surfaces, etc. It is particularly effective for areas that are prone to flow or areas that are difficult to clean, such as recesses, corners, and inside pipes. Specifically, it is suitable as a toilet cleaner, a mold remover, a ventilation R4 stain remover, and a drain pipe cleaner, and is particularly effective as a drain pipe cleaner.

The cleaning composition of the present invention further includes fillers such as mirabilite, soda carbonate, edible salt, sodium triphosphate, sodium diphosphate, tripolyphosphate, and pyrocariphosphate in the A and/or B agents; Colorants, fragrances, disinfectants, chelating agents, activators, alkalis, or other additives commonly added to cleaning agents can be added. It is preferable that these additives are added so as not to impair the stability or function of the A agent and the B agent. For example, it is preferable that a chelating agent or an activator be added to the A agent.

Hereinafter, the present invention will be explained in more detail with reference to Examples.
