Description

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

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,
Dirt such as excrement, hair, mud, bathroom grime, etc. can get clogged,
The dirt inside the drain pipe, which often adheres to the inner wall surface and obstructs the flow of water inside the pipe, is difficult to reach on hard surfaces in the home. It was one of the most difficult stains to remove.

Traditionally, the method of removing dirt from drain pipes, traps, filter pipes, etc. is to dissolve it using chlorinated hydrocarbons and activators.
A method of emulsification (U.S. Pat. No. 3,553,145), a method of decomposing dirt with sulfur and microorganisms (Special Publication of Japanese Patent Publication No. 3)
8-26465), method using sodium percarbonate and activator (JP-A-52-152406), method using acid agent, alkaline carbonate (JP-A-53'-50207), acid agent, alkaline carbonate Methods using oxidizing agents such as salt and sodium percarbonate have been reported (Japanese Unexamined Patent Publication No. 53-502 (No. 18)), but none of these methods have sufficient cleaning power.

U.S. Patent Specification No. 3,471,407 reports a method of adding strong alkalis such as caustic soda, aluminum, and inorganic nitrates, but this is extremely dangerous6. ,538,00
On the No. 8 bill, H2SO.

A method has been disclosed in which a strong acid such as hot, HNO, orthophosphoric acid, or sulfamino acid is added to silica sol, 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 remove stains from hard surfaces such as plastics, ceramics, tiles, joints, pots, 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 effectively remove odor and provide a long-term deodorizing effect.

That is, the two-dose foaming hard surface cleaning composition of the present invention has the following agents A and B, and
The agent or both contain a surfactant and separately, A;'
Terpene alcohol in l11 or B agent or both,
It is characterized by containing one or more alcohol compounds selected from cyclic terpene alcohols and their derivatives.

fl.A agent 20, 5-50% by weight hydrogen peroxide solution.

(2) Agent B: hydroxide) 0.1 to 50 in terms of IJium
An alkaline agent with alkalinity.

The present invention will be explained in more detail below. Agent A is 0.5
An aqueous solution containing ~50 tons of hydrogen peroxide, preferably tL
<Fi1-35 wt%. If the amount of hydrogen peroxide in Part A is less than 0.5%, sufficient cleaning power will not be obtained, and if it exceeds 50%, the stability will be poor and it will be dangerous to handle, which is undesirable.

Agent B is an alkaline agent with an alkalinity of 0.1 to 50% in terms of IJium, and its properties are both in solution and in solid form (powder, powder). As the main component of the alkaline agent, any alkaline substance can be used, but preferred examples include sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium sesquicarbonate, and metasilicate. Examples include sodium, sodium orthosilicate, etc., and preferred among them is hydroxide.

The alkalinity of the alkaline agent that is agent B is 01 to 50 inches, preferably 065 to 10 degrees in terms of sodium hydroxide.
It is Chi. If this value is less than 0.19g+, sufficient cleaning power cannot be obtained, and if it exceeds 50g+, stability is poor such as crystal precipitation or precipitation during storage. Extremely dangerous and undesirable.

Here, alkalinity is the titration volume obtained by titrating an alkaline agent with normal hydrochloric acid, calculated in terms of caustic soda, from the following formula.

＾ W, : Sample amount of agent B (2) A: N hydrochloric acid titration number (πl) f: Potency of terpene alcohol, 33-type terpene alcohol, or their derivatives is 0.0 in agent A and/or agent B.
It is preferable to add 0.01 to 10% by weight. This amount is 0
．． If the amount is less than 0.001 wt %, a sufficient addition effect cannot be obtained, and if it exceeds 10 wt %, the stability during storage will deteriorate. More preferably, these alcohol compounds are present in a total amount of 0.1 to 5 wt in Part A and/or Part B.
q/) can be added. Examples of terpene alcohols and sono derivatives include 2,3-dihydrogeraniol, geraniol, myrcenol, rhodinol, nerol, linalool, dihydro, ergenol, tetrahydrolinalool, dihydromyrcenol, linalyl acetate, and particularly preferred is dihydromyl. Specific examples of h13-type terpene alcohols such as senol, linalyl acetate, and geraniol and their derivatives include menthol, terpineol, and derneol,
Particularly preferred is menthol.

In the foaming cleaning composition of the present invention, a surfactant is further added to either or both of the A and B agents. The surfactant 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 anionic surfactants and nonionic surfactants are particularly preferred. It is a surfactant. Specific examples of such surfactants include the following.

(1) Anionic surfactant Fatty acid salt having 30 to 20 carbon atoms Alkyl sulfate having 0 to 18 carbon atoms xo~
l 8 alkylbenzene sulfonate carbon ses /-
18 a-olefin sulfonate carbon number is 8 to 18 and the average number of added moles of ethylene oxide (BO) EOp is 1 to 1

D = 8-10), lauryl alcohol BO adduct (EOI' = 8-10), nonylphenyl ether EO adduct 4g9 (gOP = 8-10)
Examples include nonionic surfactants such as.

In terms of stability during storage, alkyl sulfates with an average carbon number of 12, polyoxyethylene nonylphenyl ether (GOP=s~10), lauryl alcohol HO
0 adducts (For=s~10), nonylphenyl ether go adducts (EO1'=8~10), etc. are superior. Furthermore, those that are more effective in promoting penetration into dirt include alkyl sulfates with an average carbon number of 12, alkylbenzene sulfonates with an alkyl group having an average carbon number of 12, and α-olefin sulfonates with an average of 12 to 18 carbon atoms. Examples thereof include ionic surfactants such as polyoxyethylene nonylphenyl ether (EOP=8 to 10).

The surfactant is preferably added to Part A or Part B in an amount of 0.1 to 20% by weight, more preferably 05 to 10% by weight. If this total is less than 0.1% K, sufficient foaming power or foam stability cannot be obtained, and 2Q
If it exceeds %, the stability during storage will be significantly deteriorated, and the cleaning effect will also be decreased due to the decrease in the amount of active ingredients.

The properties of agent B may be liquid (solution), solid, or usually powder (powder). Particularly preferable combinations of agent A and agent B include the following combination, in which agent A or agent B further contains a surfactant of 5 to 10 wt% of KO and 0.01 wt% of KO. ~
Contains 5 w1% terpene alcohol and cyclic terpene alcohols.

(1) Liquid/liquid type A agent: 1.0 to 35% hydrogen peroxide solution B agent: 1.0 to 10% hydroxide solution (2) Liquid/powder type A solution: 1. Hydrogen peroxide solution B: Powder composition containing 30 to 100% sodium carbonate Next, the method for using and the cleaning mechanism of the hard surface cleaning composition of the present invention 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 liquid/powder Tyzo, it is more practical to first spray the powder (Part B) and then pour the liquid (Part A).

Liquid/liquid types are generally easier to handle and are convenient for applying the desired bone to any hard surface, especially hard surfaces such as hard to reach places or vertical surfaces.

Hydrogen peroxide remains relatively stable in acidic environments, but decomposes in alkaline environments. Therefore, when Agent A and Agent B come into contact with each other on hard surface dirt, nascent oxygen is generated, and the effect of oxidizing and decomposing the dirt and the cleaning effect of alkali work synergistically.

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 cleaning agent can be spread even to places where the cleaning agent is difficult to reach, such as recesses, due to the filling force 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 surfaces and vertical surfaces for a sufficient period of time necessary for cleaning.

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

As described above, in the cleaning composition of the present invention, (1) oxidizing power (2) physical external force on dirt due to foaming, filling of cleaning agent, and Adhesion or stagnation (3) The heat of reaction and the cleaning power of alkaline work synergistically to provide superior cleaning power that could not be imagined with conventional cleaning agents.
Sign. Furthermore, the terpene alcohol or cyclic terpene alcohol contained in Agent A or Agent B acts as an activator in the alkaline region, promotes and blocks the decomposition of hydrogen peroxide, and further promotes the above-mentioned stain removal effect. This increases the cleaning power and greatly reduces the processing time required for cleaning. In addition, (cyclic) terpene alcohols also have an excellent deodorizing effect, suppressing the generation of foreign odors for a long period of time after cleaning.

It is very common for 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 of a household sink.

This drain pipe has no trap, descends in a straight line, and has 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 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 the area efficiently. JP-A No. 52-152406 and No. 53-
Powdered foaming compositions have also been reported in JP 50207 and JP 53-50208;
Both foaming power is insufficient, and when applied to the above-mentioned drain pipe, it quickly flows down while foaming.

On the other hand, when using agent A and agent B of the present invention,
Both the amount of foam and the foaming power are strong, and it fills the entire inside of the drain pipe and exerts physical force on the dirt.Moreover, it slowly descends inside the drain pipe and removes the dirt for a sufficient amount of time. contact across.

As is clear from the above description, the two-component foaming cleaning composition of the present invention is effective on all hard surfaces,
It is especially effective for areas where cleaning agents easily flow, such as vertical surfaces, or areas that are difficult to clean, such as recesses, corners, and the inside of W. It can also effectively clean drain pipes, which are the most difficult to clean in ordinary homes. can.

The cleaning composition of the present invention further contains mirabilite, sodium carbonate, common salt, sodium triphosphate, sodium diphosphate, )'J't'rephosphate, and pyrrocaliphosphate in agent A and/or agent B. Bulking agents, coloring agents, fungicides, etc.
Chelating agents or other additives commonly added to 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.

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