The present invention provides a detergent composition containing 0.1 to 0.15 parts by weight.

In the detergent composition of the present invention, a very small amount of silver ion and / or copper ion is a surfactant which is a main component of the detergent, a lipid which is a stain component, and a molecule of water used for washing is hydrogen. It was developed by focusing on the fact that it divides large and small lumps generated by binding to form a single molecule or reduces the lumps.

Further, silver ions and copper ions have antibacterial activity and odor component decomposing power, and have the following features as compared with conventional detergents.

The detergency of the surfactant and the activation of the lipid degrading power and water enhance the detergency, and the rinsing becomes easy, so that the amount of the detergent used can be reduced. Since the degreasing power is excellent, the surface of the washed product becomes hydrophilic and becomes antistatic. It has excellent antibacterial and deodorant properties, and cleans washed items. Since the waste water after cleaning has a lipid decomposing power, an antibacterial power, and a filth decomposing power, the sewage tank, the sewer pipe, etc. are purified.

The surfactant (A) used in the present invention is

In particular, it acts to inhibit the molecular bonds (hydrogen bonds) of lipids and water used at the time of washing to make them monomolecular (fine molecular) or to reduce clusters. By this work,
(A) The surfactant has the original physical properties of wettability (wet
Penetration) is further improved, and emulsification / dispersion is improved. Lipids are easily separated from the washed product, and water is activated to improve permeability and solubility. Further, the silver salt and / or the copper salt (B) has a function of decomposing and deodorizing an odorous component adhering to the washed product or destroying and killing the cell membrane of aerobic fungi.

If it is less than 0.002 parts by weight, the effect of the present invention will be weakened, while if it exceeds 0.15 parts by weight, the color of the detergent will be discolored or silver or copper will be deposited and reduced on the washed product to give it a color. Is not preferable.

The detergent composition of the present invention comprises (A) and (B).
Although the components are essential, (C) water is usually added to ionize the (B) component. When the detergent composition of the present invention is in a liquid state, the blending amount of (C) water is usually 30 to 300 parts by weight, preferably 60 to 150 parts by weight, relative to 100 parts by weight of the (A) surfactant.

If the amount of (C) water is too small, the viscosity of the detergent composition will be high and the fluidity will be poor if the detergent composition is liquid, while it will be too dry and easily float if it is powdery. On the other hand, if the amount is too large, the amount used is increased in the case of a liquid, and it becomes greasy and difficult to handle in the case of a powder, which is not preferable.

Furthermore, when the remaining ammonia water is added, a transparent 1% by weight diamminesilver (I) ion liquid is formed. In this case, when the silver oxide is precipitated, the silver nitrate is removed by filtration and washing with water. It is also possible to add 3% by weight of ammonia to this to obtain a diammine silver (I) ionic liquid. Also, the water temperature and the concentration of ammonia water, the amount added,
The concentration of complex ions can be changed appropriately.

When the component (B) is silver nitrate, for example, 1 g of silver nitrate is dissolved in 99 cc of hot water at 60 ° C. to prepare a 1% by weight silver nitrate solution. When the component (B) is tetraammine copper (II) ion, for example, 1 g of copper nitrate is dissolved in 79 cc of water at 20 ° C., and 4 wt% ammonia water 20
Addition of cc gives a 1% by weight solution of tetraammine copper (II) ions. Next, 2 or more types of (A) component are put into a container, and (C) component, (B) component, and (D),
The component (E) is added and gently stirred to mix to prepare a uniform solution.

When the detergent composition of the present invention is in powder form, the component (B) is prepared by the same method as in the case of liquid form.
Next, two or more kinds of the component (A) are put in a container, the components (C), (B), (D), and (E) are added to this, and proper amount of water is further added and mixed by stirring to prepare a detergent slurry. To do. While stirring, this is heated to dry and powdered. Industrially, it is dried by a spray dryer method or the like.

The detergent composition of the present invention is capable of removing dirt by washing with water.
Deodorizing and antibacterial effects can be achieved. Specifically, first, water, the detergent composition, and the washed product are added, and the mixture is stirred for about 10 to 20 minutes and washed by a usual method. The amount of detergent used can be greatly reduced, and even in the case of severe dirt, it can be reduced to 50 to 75% of the conventional amount used. In particular, when the water temperature is 30 ° C. to 50 ° C., the cleaning effect is great, and even if the amount of the detergent is greatly reduced, the laundry can be washed sufficiently cleanly. Then, rinsing may be performed for about 3 to 10 minutes depending on the situation.

[0025]

[Function] Normally, when a washing product is immersed in a detergent solution, the surfactant penetrates into the washing product and becomes a wet state, and further acts on the dirt component, and the emulsification / dispersion function of the dirt subdivides the oily dirt into the liquid. Then, the solid particles float in the liquid. The detergent composition of the present invention promotes fine molecularization of the surfactant itself, further enhances permeability and wettability, improves emulsification / dispersion power, enhances detergency, and also acts on washing water. Then, the clusters are reduced in size, and the water is changed to water having high permeability and solubility, which contributes to improvement of detergency. Also,
The detergent composition of the present invention acts on lipids and proteins, which are soil components, to make them into fine molecules to promote decomposition and separation.

As a result, the degreasing power is greatly improved, the surface of the washed product becomes hydrophilic and the antistatic property is maintained, and this performance is maintained. Furthermore, the detergent composition of the present invention has a strong antibacterial activity that decomposes and deodorizes the odorous components adhering to the washed product, and destroys and kills the cell membrane of aerobic fungi, This performance continues even after washing. Furthermore, the waste water (sewage) after cleaning is also purified.
