Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates generally to detergents. In particular, the present invention relates to a composite detergent in which a natural cellulose powder is used as a substrate, and a detergent and vegetable brewed extract components such as rice bran and soybean brewed extract components are adsorbed and filled in this substrate, and as necessary. Therefore, auxiliary agents such as humectants, fragrances, stabilizers, and preservatives and antifungal agents are added and blended.

The first invention of the two inventions is the detergent itself, and the second invention is a method for producing the detergent.

In the past, many detergents have been invented and used. However, apart from auxiliary agents, these products do not use natural cellulose powder or rice bran/soybean extracts, so they are only effective as detergents.

On the other hand, in the present invention, by adding natural cellulose powder as a substrate and rice bran/soybean brewed extract components, etc. Natural fiber particles interact chemically and mechanically,
This increases the cleaning effect in a complex manner.

In the present invention, the inner surface of the voids of the natural cellulose powder described above is impregnated with a vegetable brewing extract component such as a rice bran/soybean brew extract component dissolved in water, and active 10H groups on the inner surface This is a composite detergent in which the voids on the outer surface are filled with detergent and, if necessary, auxiliary agents, and a method for producing the same.

However, since it was discovered that rice bran is good as a substrate,
In one example, rice bran was specifically treated as part of the natural fiber body.

The present invention was originally developed in 2. This technology was developed during research in which rice bran and soybean extracts were applied to various wood materials for the purpose of surface bleaching and cleaning.

For details on rice bran and soybean brewing extract components, see Patent No. 304
No. 840. In the present invention.

Developing new uses for rice bran and soybean extracts During a series of studies, we have conducted numerous studies based on the rice bran and soybean extracts, and have recently conducted research and development focused on new uses as detergents.

What are the major characteristics of the rice bran/soybean brewing extract components?

It's about being a natural product. Hence.

When used to bleach wood, it does not have a noticeable effect like synthetic chemicals, but it does mild bleaching and removes contaminants, giving the wood surface a glossy appearance and emitting the wood's unique aroma. .

A new fact discovered during the experimental process of the present invention is as follows.

The wood flour is brought into contact with the rice bran/soybean brewing extract.

When left in an environment under predetermined conditions, wood powder releases a pleasant aroma.

Describe the general characteristics of the plant-based brewing extracts such as the rice-soybean extracts.

(1) It is alkali resistant and acid resistant.

(2) Good permeability and surface tension.

(3) Great cleaning power.

(4) Low foaming power.

(5) Low emulsifying power.

The most important feature is that it is a natural product and is harmless to humans. It is also known for its ability to give human skin a smooth texture when washed.

On the other hand, wood has many voids, which is also utilized in the present invention.

Here, FIG. 1 is a graph showing the voids and specific gravity of the cell membrane of wood. As can be seen from this graph, wood has a large number of voids that can be used in the present invention.

However, the theoretical impregnation rate determined from the porosity of wood is as follows.

First, the relationship between the apparent specific gravity (r+) of wood and the porosity C is; 1.50 It is.

Here, when a non-polar liquid is impregnated into the wood, the liquid impregnates only the voids, so 1! If the volume of the wood (specific gravity r□) to be used is ■, and the specific gravity of the liquid is dl, the theoretical impregnated amount is; CXd,

ro×■ Therefore, the theoretical impregnation rate W1% is.

The liquid is impregnated into the pore ponds and the swollen surface of the fibers, so
This is because, when the fiber saturation point in this liquid is defined as A%, the amount impregnated into the voids is the same as in the case of 1.0.

Therefore, the theoretical impregnation rate W2% is It is.

This is expressed graphically in the graph of specific gravity (0) and theoretical impregnation rate (W) in Figure 2.

Here, in a non-polar solvent; Q What is the porosity?

1.50 therefore.

On the other hand, in polar solvents; (However, +dl is the specific gravity of the solution.

In the graph, d1=0.9. ) Applying these, the two inventions were made as follows. In other words, the first invention of the nine inventions is that vegetable brewing extract components such as rice bran and soybean extract components are adsorbed on the inner surface of the natural cellulose powder that is the substrate, and the outer surface is further filled with detergent. It is a complex powder detergent made with

A) In both texts, the external surface refers to the intracellular lumen, intracellular communication pores, wall pore membrane pores, and minute voids within the intercellular walls. In other words, there are voids of various sizes in wood, and the total number of voids on the external surface is 25 to 85% of the entire wood.
%, and their diameters vary from those visible to the naked eye to those that can be seen with a W4121 mirror. The surface area of these is 103 cm2/g.

B) Also, the internal surface is: the surface of temporary capillaries created within the cell membrane due to the presence of a swelling agent such as water. This surface area is 10" cm2/g, and it is highly reactive and adsorbs substances well. For example, at a specific gravity of 0.4, the porosity of wood is 73.3% and the real part is 26.7%. ,
The internal surface is the surface of the temporary capillaries that occur in this parenchyma. Now, for lumber with a specific gravity of 0.4, the external surface is 2
×103crR218 or so, and the internal surface is 2×1
It is about 0" cm2/g.

C) Furthermore, detergent is a general term for substances used for the purpose of cleaning solid surfaces by removing dirt attached to them.

There are many types of these depending on the target substance, such as soap and synthetic detergent.

This detergent includes all detergents currently on the market and those sold as intermediate products by companies in the chemical industry, but they can be roughly divided into two: detergents for cleaning human skin, and detergents for industrial use, such as those for cleaning floors. It can be divided into car body cleaning for materials.

D) Therefore, the substrate is natural cellulose powder.

In other words, wood flour such as hiba, cypress, cedar, cherry blossom, and lauan, fibers such as cellulose, bulbs, and paper, and grains such as rice bran and soybeans.
AIi! , is a powder of wA fibers from other plants.

E) Plant-based brewed extract components are components extracted by brewing plant-based products such as rice bran and soybeans.

F) The auxiliary agent mentioned below is a general term for wetting agents, fragrances, inorganic powder fillers and stabilizers such as clay, kaolin, and titanium dioxide, and preservatives and antifungal agents.

However, if we take wood flour as an example of the substrate of the present invention.

The external space, which is a macroscopic void in the wood powder, is filled with detergent and auxiliary agents. Then, vegetable brewing extract components such as rice bran and soybean brew extract components are adsorbed on the internal surface (swelling surface). Therefore, during low-temperature vacuum drying, the water that is the solvent for the rice bran/soybean brewing extract components and the water that dissolves the detergent and auxiliary agents are scattered during the drying process.

Therefore, a new type of composite detergent is created in which rice bran/soybean brewing extract ingredients and detergent/auxiliary agents are adsorbed or filled on each of the two surfaces of the wood flour, which shows no apparent change in appearance.

This new type of complex detergent can be used as is or, if necessary, can be made into tablets or creamed with a little water and packed into tubes. When using, add the required amount of water and use the same amount as regular powder detergent.

The composite powder detergent according to the present invention has a wide variety of uses, from bath detergents to industrial uses. Hence.

The effectiveness and cleaning power can be changed by changing the formulation according to the purpose. For example, it is used for industrial flooring, especially when cleaning building lobbies.

Not only does it absorb dirt well, but it also prevents the metal used from rusting. In addition, it has been discovered that there are many other uses, such as for cleaning carpets and car bodies, depending on the formulation, type of substrate, particle size of the substrate, etc.

As a substrate for complex detergents that humans use directly and come in contact with the skin,
It is better to use wood powder from Hiba wood, Hinoki, Sugi, Sakura, etc. and perform cold water washing or hot water extraction treatment as necessary. On the other hand, although tree species are not so selected as substrates for industrial detergents, it is better to avoid wood powder from lauan wood stored in Nagatoma sewage. In the case of substrates for industrial detergents, it is also desirable to perform cold water washing or hot water extraction treatment. Bulb cellulose powder is suitable as a substrate for the natural fiber material.

All detergents that exert a cleaning action belong to surfactants, and their chemical structure has a hydrophilic group that is easily compatible with water and a hydrophobic group that is not compatible with water, and each has a binding energy. Maintains an appropriate balance between strength and strength.

There are two types of detergents: detergents that clean human skin and industrial detergents.

Even for use on humans, it is used in the bath.

Detergents are further classified according to their purpose, such as detergents for washing hands with oil stains. For example, when touching two people's skin, skin mildness is important.

It is best to use alcohols made from natural oils and fats.

To explain the above detergent by product name, it has the chemical structure -0OC-C)I2-C)I2-CH-COO-C0- manufactured from L-glutamic acid, a type of amino acid, and natural fatty acids, manufactured by Ajinomoto Co., Inc.
NH RCO-: Salt of fatty acid has properties as an anionic surfactant.

It varies depending on the type of fatty acid and base.

For industrial use, it is important to place importance on washability.

An example of this is triethanolamine salt manufactured by Nippon Oil & Fats Co., Ltd., with the product name "Nira Sambar Soft SFT".
There are EFT, SLT, ELTJ, etc.

In addition, auxiliary agents may be added as necessary. These detergents and auxiliaries are loaded onto the external surface of the wood.

The above explanation will be illustrated according to the model of the internal pores of the natural fiber body shown in FIG. First, there is an external surface 2 of a natural fiber body l. A detergent 3 and an auxiliary agent 4 are filled in layers in the wall of this external surface 2. The inner surface 5 of this natural fiber body 1 swells to a large degree when a polar solvent is present, and shrinks as it dries. This internal surface 5 contains a vegetable brewing extract component 6 such as rice bran and soybean extract component.
is adsorbed.

We have also developed various long-lasting preservatives and fungicides by utilizing the structural structure of wood as described above. For example, wood powder is adsorbed and filled with preservatives, fungicides, deodorizers, fragrances, etc., and then spread as an underlay for two tatami mats or a carpet. Adsorbs to wood powder
Each filled drug does not release its effects all at once, but maintains its effects over a long period of time. Time for annual deep cleaning.

After removing the tatami mats and spraying a mist of water on the treated wood powder scattered on the floor, we were able to collect dust and other particles without scattering them when swept, confirming that the method is suitable for cleaning work. .

Next, a method for producing a composite powder detergent according to the second invention of the two inventions will be described below.

First, a 10-500 mesh substrate with a moisture content of 1-20% is immersed in a 10-30% aqueous solution of plant-based brewing extracts such as rice bran and soybean extracts, and then rice bran and soybean extracts. The plant extract is removed from the aqueous solution and dried. Next, the moisture is removed by evaporation, and then the sample is immersed again in an aqueous solution containing a detergent for a predetermined period of time. The wood powder is then taken out and dried. Then, when the moisture content has decreased to around 5-20%, take it out. In this state, vegetable brewing extract components such as rice bran and soybean brew extract components are adsorbed on the inner surface of the wood flour, and a composite powder detergent is obtained in which the outer surface of the wood flour is filled with detergent.

Next, two embodiments of the method for producing the above-mentioned composite powder detergent of the present invention will be described in detail.

First, 100 to 150 mesh of Hiba wood flour with a moisture content of 5 to 10% is immersed in a 20% aqueous solution of plant-based brewing extracts such as rice bran and soybean extracts, and then rice bran and soybean extracts. etc., taken out from the aqueous solution and air-dried. Next, the moisture is removed by evaporation, and then the cloth is immersed again in an aqueous solution containing detergent and perfume for a predetermined period of time.

Thereafter, this wood flour is taken out and forcedly dried in a hot air dryer at around 50°C. Then, when the moisture content is around 10-12%, it is taken out. In this state, vegetable brewing extracts such as rice bran and soybean extracts are adsorbed on the inner surface of the wood flour, detergent is applied to the outer surface of the wood flour, and in this example, a composite powder is filled with fragrance. Detergent is obtained.

When using this for hand washing, please do the following.

First, a small cylindrical jig is used to compress the detergent to 5 to 6 kg/cm 2 to create a disk-shaped solid detergent. When using, press the disk detergent lightly on the palm of your hand to crush it. So, if you pour water from the tap on your hands and rub your palms, bubbles will form and remove the oil and dirt that is stuck in the pores of your palms.

Alternatively, the substrate is immersed under predetermined conditions in an aqueous solution in which a vegetable brew extract such as rice bran or soybean extract, detergent, and auxiliary agents are mixed in advance, and then dried. There is also a manufacturing method that removes moisture.

When considering the maintenance of the composite detergent, we investigated clogging between the sink, the sewer system, and the manhole, and found no problems. In addition, because plant-based brewing extracts such as rice bran and soybean extracts were dissolved in the manhole, abnormal fermentation was prevented and odor control was also observed.

Below, some 151 specific examples other than those mentioned above are shown.

In the first specific example, first, 100 g of air-dried Hiba wood flour after hot water extraction was put into 200 g of an aqueous solution of 20% rice bran/soybean brewing extract.

After stirring well for 15 minutes, remove the wood flour from the aqueous solution and squeeze it well. At this time, the amount of rice bran/soybean brewing extract component aqueous solution impregnated is about 190%. and.

Remove moisture in a hot air dryer at around 50°C and take out into a beaker.

After that, Amine Soft C5-11 (coconut oil fatty acid) 1
0% water soluble) At night, add a small amount of igA fragrance to the aqueous solution.
Make 00g and add rice bran taken out from the dryer to this aqueous solution.
Add hiba wood powder adsorbing soybean brewing extract ingredients and stir well. Thereafter, this was left to stand for 10 minutes, taken out from the aqueous solution, squeezed tightly to remove the superagent aqueous solution, and then air-dried in a hot air dryer at around 50°C.

As a result, the rice bran and soybean extract components are adsorbed on the inner surface of the hiba wood powder, and a granular composite detergent is created with the outer surface filled with detergent and fragrance.

This granular detergent can be packaged as is, or 5kg/
Tablets were made using a pressure of about cm2 and the product was made into tablets.

In the second concrete example, first, 200 g of washed hiba wood flour and 100 g of rice bran/soybean brewing extract ingredient 25
% aqueous solution. And this is 1
After stirring well for 0 minutes, let stand well for 15 minutes. Then, the wood powder is taken out from the aqueous solution, coated well, and dried at around 50°C.

On the other hand, a 20% aqueous solution of soft amine LS-11.

Dry wood flour adsorbed with rice bran/soybean brewing extract components is added to 200 g of an aqueous solution to which a very small amount of fragrance is added.

Then, stir this well and leave it for 10 minutes, then take out the wood flour from this aqueous solution and dry it. Then, the rice bran and soybean brewing extract components are adsorbed on the internal surface of the Hinoki wood powder.
A granular composite detergent is obtained whose outer surface is filled with detergent and fragrance.

Next, the third specific example will be explained first.

1100g of rice sieved into 50 mesh pieces, rice bran,
Add Amisof C to 200g of an aqueous solution of 40% soybean brewing extract.
Pour into an aqueous solution containing 100 g of a 30% aqueous solution of T-12. After stirring this for about 20 minutes, about 30 minutes
Leave for a minute. Thereafter, the rice bran was removed from the aqueous solution and air-dried. Then, after the water has evaporated, it is packed into a cloth bag.

First, let's look at the fourth specific example.

Put 100g of washed Karamatsu mesh into a beaker, and add 1 to 1 Newrex (also known as Seiso 550) to 0.00 g.
Pour 200 g of a 30% aqueous solution containing Starhome MF (1) and 200 g of a 20% aqueous solution of rice bran/soybean brewing extract into a beaker, continue stirring for 20 minutes, and leave the barley as it is for 30 minutes.

After that, take out the pine wood flour from the beaker and add 5
Force dry at 0°C. This is used as a floor cleaning compound detergent.

Finally, the fifth specific example is as follows.

Washed wood mill waste wood flour (50-60 mesh) 1
Put 00g into a beaker. Then add Persof) SL and Starhome in a ratio of 1 to 0.1. Furthermore, 50 g of a 30% aqueous solution to which a very small amount of anti-mold agent was added and 150 g of a 30% aqueous solution of rice bran/soybean brewing extract were mixed, then poured into a beaker and kneaded for about 30 minutes.

When 200 g of this kneaded material is air-dried at 50°C, the water content gradually evaporates. Therefore, lightly knead this with your hands to break it up.

This detergent was used for cleaning flooring.

One feature of the composite powder detergent of the present invention is that the wood flour particles promote the cleaning effect of dirt and oils that are clogged in the pores of the skin and the fine lines of the palms of the hands. This is because wood flour particles play a mechanical role.

A man-type composite detergent is produced by using rice 11ai (30 to 60 mesh) as a substrate and adsorbing rice bran/soybean brew extract components, detergents, and auxiliaries into the internal space of the rice bran.
Unlike the cleansing power of rice bran alone, it removes dirt from the skin well and foams well, confirming that the rice bran and soybean extract ingredients act on the skin and make it smooth.

The composite powder detergent and manufacturing method according to the present invention are as follows.

Due to the above structure, the following detergent has a very high cleaning effect. And, such a detergent with high cleaning effect could be produced by the simple method described above.

First, we investigated the cleaning effect.

The following was discovered.

In other words, since the surface of wood flour is covered with hydrophilic groups, substances with low surface tension such as rice bran/soybean brewing extract components, detergents, and auxiliary materials that are adsorbed or filled in the substrate easily separate from the substrate. The cleaning action contributes here. However, these substances are adsorbed and filled inside the solid wood powder. Therefore, it is sustainable without being suddenly separated from the wood powder.

This can also be said to be a feature of the composite powder detergent of the present invention. The rice bran/soybean brewing extract components, detergents (soaps, synthetic detergents, etc.) and auxiliary agents released from the wood flour substrate are dissolved in water and exhibit cleaning power. However, the cleaning action of two soaps is due to the chemical properties of their molecules, such as adsorption and surface activity, and these properties are exhibited only in an aqueous solution.

These soaps and synthetic detergents are easy to absorb and penetrate.

It is a complex phenomenon that combines many phenomena such as adsorption, dispersion, emulsification, and prevention of redeposition, but the two functions are to lower the interfacial tension between the dirt attached to the cleaning object and the cleaning solution, and to moisten and penetrate. First, the detergent adsorbs the dirt and disperses or suspends it into fine particles.

In this case, stubborn stains require the assistance of mechanical agitation or friction, and during this mechanical agitation and friction, particles such as wood flour are used to assist in the composite powder detergent of the present invention. It has a different effect than conventional single detergents, and can clean dirt from even the smallest details.
