ABSTRACT:
TECHNICAL FIELD
The present invention relates to a cleaning composition and a method of preparing the same.
BACKGROUND ART
Soaps are superior in terms of biodegradability, and are said to be good for the environment. On the other hand, soaps suffer from the drawback of a weak cleaning power and antimicrobial power. As a result, synthetic cleaning agents (synthetic detergents) currently constitute the mainstream of cleaning agents.
Agents which contain higher alcohol type sulfuric acid esters, petroleum type alkylbenzenesulfonic acids, amino acid type alkylamino acids and the like as their chief components, and which also contain artificial chemical substances, polishing agents, moisture retaining agents and the like, are widely used as synthetic cleaning agents.
However, such synthetic cleaning agents are a problem in terms of environmental contamination. Synthetic cleaning agents seep into the ground and contaminate the ground water, soil and the like, so that such agents have a deleterious effect on the environment and on human beings. For example, octylphenol, which is widely used as a raw material in synthetic cleaning agents, is an artificial chemical substance that is considered to be an environmental hormone or endocrine-disrupting chemical; this substance remains intact without undergoing degradation. In fact, octylphenol has been detected in many seas, rivers, lakes and the like.
Furthermore, water pollution, red tides and the like are created by the flow of common waste water containing these synthetic cleaning agents into the ocean. Such problems are especially serious in areas that lack sewage treatment facilities.
Moreover, synthetic cleaning agents are finely classified according to use, such as kitchen use, general household use, toilet use, laundry use, lavatory use, automotive use and the like; as a result, not only is such specialized use bothersome for the consumer, but used containers are generated in large quantities.
There are also problems regarding synthetic cleaning agents that are used in various applications. For example, cleaning agents used for general cleaning contain trichloroethylene; however, there is a danger that this may be a carcinogenic substance. Cleaning agents used on the hair (shampoos), as well as cleaning agents used on the body and the like, are weakly acidic; synthetic surfactants or the like must be added to these agents, and such surfactants are a cause of water pollution. In the case of cleaning agents used on bathtubs (anti-mold agents and the like), care must be taken so that the agents do not contact the body.
Thus, although synthetic cleaning agents are superior in terms of cleaning power and the like, such agents are a source of environmental problems such as water pollution and the like. As a result, cleaning agents that have the cleaning power and anti-microbial power of synthetic cleaning agents with the safety of soaps is urgently required. However, such cleaning agents have not yet been developed or adapted for practical use.
DISCLOSURE OF THE INVENTION
It is a principal object of the present invention to provide a cleaning composition which combines a superior cleaning power, anti-microbial power and the like with a high degree of safety.
With the foregoing problems of the prior art in view, the present inventor conducted diligent research; as a result of this research, the inventor discovered that a specified composition makes it possible to achieve the above-mentioned object. This discovery led to the perfection of the present invention.
Specifically, the present invention relates to the cleaning composition described below, and a method of manufacturing the same.
1. A cleaning composition which is characterized in that this composition is obtained by adding a soap to a mixture containing a silicic acid compound, an aluminum compound and water, or a solution of the same.
2. The cleaning composition described in 1 above, wherein the silicic acid compound consists of at least one compound selected from a set consisting of silicates and silicic acid.
3. The cleaning composition described in 1 above, wherein the aluminum compound consists of at least one compound selected from the group consisting of aluminum oxide and aluminum hydroxide.
4. The cleaning composition described in any of 1 through 3 above, wherein clay is used as all or part of the silicic acid compound.
5. A method of preparing a cleaning composition comprising the steps of preparing a mixture containing a silicic acid compound, an aluminum compound and water, and then adding a soap to the mixture or a solution of the same.
6. The method described in 5 above, wherein clay is used as all or part of the silicic acid compound.
7. The method described in 5 above, wherein the preparation of the mixture is performed at a temperature of 80° C. or greater.
8. A cleaning composition which is characterized in that that this composition is formed by adding a soap to a mixture containing kaolin, sodium silicate, aluminum hydroxide and water, or a solution of the same.
9. The cleaning composition described in 8 above, wherein the mixture further contains at least one compound selected from a set consisting of sodium meta-silicate and sodium carbonate.
10. The cleaning composition described in 8 above, wherein the mixture contains 50 to 200 parts by weight of sodium silicate, 50 to 200 parts by weight of aluminum hydroxide and 300 to 3000 parts by weight of water per 100 parts by weight of kaolin.
11. A method of preparing a cleaning composition which is characterized in that a mixture containing kaolin, sodium silicate, aluminum hydroxide and water is prepared, after which a soap is added to the mixture or a solution of the same.
12. The method described in 11 above, in which the mixture further contains at least one compound selected from the group consisting of sodium meta-silicate and sodium carbonate.
13. The method described in 11 above, in which the mixing of the mixture is performed at a temperature of 80° C. or greater.
(1) Cleaning Composition
The cleaning composition of the present invention is characterized in that this composition is formed by adding a soap to a mixture containing a silicic acid compound, an aluminum compound and water, or a solution of the same.
There are no particular restrictions on the silicic acid compound used, as long as this compound is an inorganic silicic acid compound. Usually one or more compounds selected from the group consisting of silicates and silicic acid (and especially silicates) can be used. Examples of silicates that can be used include silicates of alkali metals such as sodium silicate (sodium ortho-silicate, sodium meta-silicate and the like), potassium silicate and the like, silicates of alkaline earth metals such as calcium silicate, magnesium silicate and the like, and other silicates such as aluminum silicate and the like. Known compounds or commercially marketed compounds may be used as these silicic acid compounds.
In the present invention, clay may be used as all or part of the silicic acid compound. There are no particular restrictions on the clay used, as long as this clay contains a silicic acid compound as a clay mineral. For example, a clay containing kaolinite (i.e., kaolin) may be used. In the present invention, it is desirable to use kaolin and sodium silicate (water glass) as silicic acid compounds.
There are no restrictions on the aluminum compound used; usually one or more compounds selected from the group consisting of aluminum oxide and aluminum hydroxide may be used. Furthermore, salts such as aluminum sulfate or the like may also be used. Known compounds or commercially marketed compounds may be used as these aluminum compounds.
The amount of aluminum compound used may be suitably determined according to the type of aluminum compound that is used. Usually this amount may range from about 50 to 200 parts by weight, preferably from 60 to 100 parts by weight, per 100 parts by weight of the silicic acid compound used.
In the composition of the present invention, carbonates may also be added as re
