BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple method for producing a divided detergent having good solubility.

[0002]

2. Description of the Related Art Most of the granular detergents for clothes currently on the market are sold in a carton of 500 g to 5 kg or a plastic bag, and when used, they are weighed one by one with a cup or spoon, or It is common to add an appropriate amount to the washing bath. At this time, if an appropriate amount of detergent is not measured, there arises inconveniences that a sufficient cleaning effect cannot be obtained, or the detergent is wasted excessively. In addition, there are problems that the detergent may be spilled in the vicinity when the detergent is weighed, and the hand may become slippery. On the other hand, there are also commercially available detergents in which the amount used for one time is individually packaged. This detergent is disclosed in JP-A-63
As described in JP-A-39640, a polymer film such as polypropylene is used as a packaging material, and the bag must be torn and taken out at each use.
The method of use is complicated. Further, in this case, there is a problem that the fine powder of the detergent rises up, and dissatisfaction remains in terms of usability. In recent years, as a new form, one in which a detergent can be put in a washing bath while being put in a bag is commercially available. As described in JP-A-64-56799, this is a product in which granular detergent is individually packaged with a non-woven fabric once, but since the non-woven fabric is not soluble in water, a bag is not formed after washing. It is troublesome to find and discard the non-woven fabric from the remaining and washed clothes.

Further, a polyvinyl alcohol film described in JP-A-6-116598 or a water-soluble film or sheet such as a carboxymethyl cellulose sheet described in JP-A-47-43005 is packaged with a detergent individually. It is also being considered. However, in any of these cases, the granular detergent must be once produced by a method such as spray drying or spray drying + high bulk density, which requires a lot of manufacturing equipment, and the control operation is complicated. It is by no means a preferable method in terms of saving resources and energy. By the way, JP-A-63-1
Japanese Patent No. 2466 describes a method of filling a water-soluble film with a surfactant-containing paste mixture having a viscosity of 100 to 10,000 poise (25 ° C) and an alkali builder. However, in this method, the surfactant is once mixed with a detergent component other than the alkali builder to form a paste-like mixture having a viscosity of 100 to 10000 poise (25 ° C.), which is water-soluble without contact with the alkali builder. Since the film has to be filled, the operation is complicated, and the viscosity of the pasty mixture is high, so that there is a problem in the clogging of the piping and the measuring accuracy.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a simple method for producing a divided detergent having good solubility.

[0005]

Means for Solving the Problems The inventors of the present invention have made extensive studies in order to achieve this object, and as a result, have found that powder physical properties such as fluidity, particle size, and caking property of conventional granular detergents are inferior in production or quality. It is important to note that in the case of a packaged detergent, it is not necessary to consider the physical properties of the detergent inside, and if the required amount of the detergent raw material is packaged in a predetermined amount, the quality is not compromised.
It has been found that a packaged detergent can be easily produced. That is, in producing a divided-pack detergent containing a surfactant solution having a viscosity at 50 ° C. of 100 poise or less and a water content of 30% by weight or less, and a detergent builder powder, the detergent builder powder is removed from a water-soluble sheet. By filling the separate packaging container, then the surfactant solution, and then closing the packaging container, the equipment is simple, no complicated operation is required, and there is no hindrance to weighing and pipe transportation. It was found that there is no problem, and there is no problem in the stability of the packaging container and the solubility of the detergent, which is a concern in the packaging detergent. In addition, a precursor that is a raw material of a surfactant, for example, an acid-type surfactant raw material is directly used, and the alkali builder powder and the precursor of the surfactant are sequentially filled in a packaging container to form a surfactant. Since the neutralization process and the production of the detergent are completed in the process of producing the divided-type detergent without undergoing the neutralization process for producing We have found that a method is provided. The present invention is based on these novel findings.

As the precursor of the surfactant, any raw material which becomes an anionic surfactant in the neutralization step can be used without particular limitation. Such precursors include:
Examples include acid type precursors. The acid-type precursor, when filled in a sachet container following the alkali builder powder, reacts with the already filled alkali builder powder to form a surfactant in situ. . Examples of such an acid type surfactant raw material include compounds such as sulfonic acid, carboxylic acid, sulfuric acid ester, and phosphoric acid ester. Specifically, examples of the sulfonic acid include linear alkylbenzene sulfonic acid (common name: LAS-H), α-sulfo fatty acid methyl ester (common name: SF-H), α-olefin sulfonic acid (common name: AOS-). H) and the like. Examples of the carboxylic acid include lauric acid and saturated or unsaturated higher fatty acids such as palmitic acid, oleic acid and stearic acid.

Furthermore, examples of the phosphoric acid ester include lauryl phosphoric acid, oleyl phosphoric acid, and polyoxyethylene lauryl phosphoric acid.

The above-mentioned surfactants or precursors thereof may be used alone or in combination. The surfactant solution filled in the packaging container according to the present invention includes a surfactant solution containing no water and a surfactant solution containing water. When the surfactant solution contains water, the water content of the surfactant solution is 30% by weight or less, preferably 20% by weight or less, particularly preferably 10% by weight or less. By setting the water content to 30% by weight or less, it is possible to effectively suppress the deterioration of the packaging container formed from the water-soluble material described below, and enhance the storage stability as a packaging detergent. You can In order to obtain good solubility of the detergent, the water content should be at least 1% by weight,
Suitably 3% by weight is suitable. On the other hand, the amount of the surfactant in the surfactant solution is preferably 15
-50% by weight, more preferably 15-35% by weight, particularly preferably 15-35% by weight. In this range,
Sufficient cleanability can be obtained, and deterioration of the packaging container can be suppressed. The surfactant solution has a viscosity at 50 ° C. of 100 poise or less, preferably 80 poise or less, more preferably 60 poise or less. By setting the viscosity in this range, the transportability and meterability of the solution of the surfactant at the time of filling the divided-pack detergent are excellent, and the penetration into the detergent builder used in combination becomes good. Good penetration into the detergent builder is preferable because deterioration of the packaging container can be suppressed. On the other hand, the minimum viscosity at 50 ° C is
It is usually 0.2 poise, preferably 0.5 poise.

The surfactant is preferably contained in the detergent composition (total amount of the solution of the surfactant and the detergent builder) in an amount of 15 to 15.
The content is 50% by weight, more preferably 15 to 40% by weight, and particularly preferably 15 to 35% by weight. This amount is 15
If it is less than 5% by weight, a sufficient cleaning effect cannot be obtained, while 5%
When it exceeds 0% by weight, the divided package is deteriorated by the surfactant, and the divided package becomes sticky or is broken in an extreme case. When the precursor of the surfactant is filled in the packaging container, it reacts with the alkali builder powder in the packaging container to form an anionic surfactant solution having the above-mentioned properties in situ. It may be filled in such an amount. Such amounts include the type and amount of precursor used,
Furthermore, it can be easily and appropriately selected by adjusting the water content and the like. For example, when the precursor is used in an aqueous solution, a suitable water content is usually 0.5 to 25% by weight, preferably 1 to 15% by weight. In this case, the viscosity of the precursor is, for example, 0.5 to 50 poise, usually 1 to 30 poise. A viscosity within this range is suitable because the neutralization reaction can be carried out efficiently. As the washing builder powder used in the present invention, various builders such as an inorganic builder and an organic builder can be used. Examples of preferable builders include the following. 1) Aluminosilicates such as A-type zeolite and amorphous zeolite. 2) Layered polysilicates such as macatite and kanemite. 3) Smectite minerals such as montmorillonite and hectorite. 4) Condensed phosphates such as sodium tripolyphosphate and sodium pyrophosphate. 5) Alkali builders such as sodium carbonate, potassium carbonate and sodium silicate. 6) Aminopolyacetates such as nitrilotriacetate and ethylenediaminetetraacetate. 7) Polyvalent carboxylates such as citrate and succinate.

The above washing builder powders may be used alone or in combination. The particle size of the above washing builder powder is not particularly limited, but the average particle size is preferably 1
Those having a thickness of 000 μm or less, more preferably 500 μm or less are used. With such an average particle size, the cleaning effect and the detergent solubility are good. However, from the viewpoints of workability due to generation of fine powder, measurement accuracy during filling, and the like, it is appropriate that the particle size of the detergent builder powder is at least 100 μm or more, preferably 150 μm or more. JIS K6220
The oil absorption of the detergent builder defined by
It is at least 40 ml / 100 g, particularly preferably at least 50 ml / 100 g. By using a detergent builder having such an oil absorption amount, deterioration of the packaging container can be suppressed. However, if the oil absorption is too large, the strength of the builder particles tends to decrease and the work environment is likely to deteriorate due to the generation of fine powder, so the maximum oil absorption is usually 500 ml.
/ 100 g, preferably 300 ml / 100 g. The washing builder powder is preferably 50 to 85% by weight, more preferably 60 to 85% by weight, particularly preferably 65 to 65% by weight in the detergent composition (the total amount of the surfactant solution and the detergent builder powder).
It is contained at 85% by weight. By using the detergent builder powder in an amount within this range, the washing property and the suppression of deterioration of the packaging container are improved.

The packaged container used in the present invention is made of a water-soluble polymer material. Examples of such water-soluble polymer materials include water-soluble cellulosic materials and water-soluble synthetic polymers. Among these, examples of the material that easily forms a sheet include a water-soluble cellulose-based material, and specific examples thereof include carboxymethyl cellulose and carboxyethyl cellulose. As the water-soluble synthetic polymer, for example, polyvinyl alcohol film (PVA, partially saponified PVA, modified PVA) or the like is preferably used. Water soluble polymer materials other than these materials may be used in combination with the above materials. For example, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose,
Polyvinylpyrrolidone, sodium polyacrylate, starch,
Examples include agar and casein. The packaging container is made by weaving fibers made of a water-soluble polymer material as a base fabric, a non-woven fabric made of fibers of such a water-soluble polymer material, and further, such a water-soluble polymer material. It can be manufactured from a film-like sheet. The shape of the packaging container is not particularly limited as long as it can hold the detergent builder and the surfactant solution. The shape of the packaging container can be easily selected appropriately by those skilled in the art in consideration of, for example, the handling easiness of the packaging container. For example, the packaging container is a woven or non-woven fabric made of a water-soluble polymer material,
Alternatively, it can be manufactured by folding the sheet in half and heat-sealing the side portion with a water-soluble heat-sealing material, for example, a polymer material such as water-soluble polyvinyl alcohol, so that the upper opening is left as a filling port. In this case, the shape of the packaging container is, for example, a rectangular bag-shaped packaging container such as a tea bag. Also, the method of closing the filling port of the packaging container is arbitrary, for example, by bonding the material forming the filling port to each other via the water-soluble heat-sealing material used to manufacture the packaging container. The filling port may be closed by

The packing rate of the detergent builder and the surfactant solution in the packaging container is preferably 80% by volume or more, more preferably 90% by volume or more. If the filling rate is lower than this, the air in the packaging container may expand or contract due to changes in the surrounding temperature, which may damage the container, which is not preferable. Into the divided-type detergent composition of the present invention, various components usually added to detergents can be added without limitation. Examples of such components include the following components. In this case, these components may be blended in the surfactant solution or precursor, or may be blended in detergent builder powder such as alkali builder powder. 1) Liquid cleaning builder: polyacrylic acid salt, polyacrylic acid-maleic acid copolymer, etc. 2) Fluorescent agent: bis (triazinylamino) stilbenedisulfonic acid derivative, bis (sulfostyryl) biphenyl salt [Tinopearl CBS] and the like. 3) Enzymes: lipase, protease, cellulase, amylase, etc. 4) Bleach: Percarbonate, perborate, etc. 5) Antistatic agent: a cationic surfactant such as a dialkyl type quaternary ammonium salt. 6) Anti-redeposition agent: Cellulose derivative such as carboxymethyl cellulose. 7) Bulking agents: sodium sulfate, potassium sulfate, sodium chloride and the like. 8) Reducing agents: sodium sulfite, potassium sulfite, etc. 9) Fragrance. 10) Antifoaming agent such as silicone. 11) Oil-absorbing carriers such as amorphous silica, calcium silicate, and calcium carbonate.

Next, the method for producing the divided-type detergent of the present invention will be described. The packaged detergent of the present invention is, for example, filled in a packaging container made of a water-soluble polymer material through a filling port, sequentially filling a detergent builder powder and a surfactant solution, and then filling the packaging container with a filling port. It can be manufactured by closing. In this case, the surfactant solution is impregnated into the already filled detergent builder powder. When the surfactant solution has a viscosity of 100 poise or less at 50 ° C. and a water content of 30% by weight or less at a temperature of 50 ° C., the packaging container made of a water-soluble polymer material is not deteriorated by the surfactant solution. Can prevent problems. In addition, the packaging container during the filling of the surfactant solution is 5% in order to prevent deterioration of the packaging container.
It is suitable to keep the temperature for more than 50 ° C. for a time of not less than 3 minutes, preferably not less than 3 minutes, particularly preferably not less than 0 minutes. When the temperature of the packaging container is 5 minutes or more and 50 ° C. or more, there is a problem of deterioration of the packaging container due to the surfactant solution. However, as long as the temperature of the packaging container does not reach a temperature of 5 minutes or more and 50 ° C. or more, the temperature of the surfactant solution to be filled may exceed 50 ° C.
For example, the temperature of the surfactant solution is, for example, 80
The temperature can be set to around 70 ° C, preferably around 70 ° C. In this case, the packaging container, during the filling of the surfactant solution,
In some cases, it is necessary to cool the temperature of the packaging container in order to keep it at 50 ° C or lower.

A preferable filling method can be performed, for example, as follows. (1) Prepare a surfactant solution. (2) Prepare a washing builder powder. (3) The surfactant solution and the washing builder powder are transported to a packaging package place, and the detergent builder powder and the surfactant solution are weighed in a continuously-flowing packaging package container, respectively, and sequentially. , Fill the packaging container. (4) Close the filling port of the packaging container. In the step (1), raw materials such as a fluorescent agent, a cationic surfactant, a fragrance, a silicone, and a liquid cleaning builder can be added to the surfactant solution using a general mixing / stirring tank. In the step (2), components such as an enzyme, a bleaching agent, an extender, a reducing agent, an anti-soil redeposition agent, and an oil-absorbing carrier can be added to the detergent builder using a general powder mixer. . Alternatively, the detergent builder powder may be slurry-mixed and spray-dried. In the step (3), the temperature of the packaging container at the time of filling the surfactant solution is 50 ° C. or lower, preferably 45 ° C. or lower,
Particularly preferably, it is 40 ° C. or lower. When it exceeds 50 ℃,
During the manufacturing process, the material of the packaging container may deteriorate and eventually the packaging container may be damaged. When the temperature of the surfactant solution itself is, for example, 70 ° C. or higher, among the surfactants, the surfactant having an ester bond may be hydrolyzed to reduce the detergency. On the other hand, if the temperature is too low, the viscosity of the surfactant solution becomes high and it becomes difficult to fill the surfactant solution, and it becomes difficult to soak into the already filled detergent builder powder. Therefore, the minimum temperature is, for example,
A temperature of 15 ° C, preferably 20 ° C, is suitable.

In the step (4), the packing container can be easily closed by heat-sealing the filling port of the packing container with, for example, a heat-sealing material. on the other hand,
Similar to the case of filling the surfactant solution, the precursor of the surfactant is filled while maintaining the temperature of the packaging container so as not to reach a temperature of 5 minutes or more and 50 ° C. or more.
