Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge cleaning agent which has excellent detergency against dirt on a hard surface and is particularly suitable for a cleaning machine and a method for producing the same.

[0002]

2. Description of the Related Art In recent years, automatic dishwashers have rapidly become widespread in kitchens of hotels, restaurants and catering centers from the viewpoints of labor shortage, organization of working environment, hygiene management and the like.

Conventionally, as a detergent for such a commercial automatic dishwasher, powder containing a large amount of a strong alkali agent,
The liquid type was the mainstream, but recently, the safety of workers,
From the viewpoint of ease of use and the like, cartridge cleaning agents have become widespread. Further, with the outbreak of food poisoning and the like, cartridge cleaning agents containing a bleaching agent have become widespread.

[0004] However, these cartridge cleaning agent supply methods generally involve setting the cartridge cleaning agent upside down on a supply machine.
The method is to sequentially dissolve the cleaning agent while spraying water from a nozzle, and in most cases, the cleaning agent in a powder state is loosely stored in a cartridge.

[0005] Therefore, in these cartridge cleaning agents, the particles are very easy to flow in the cartridge, and the particles move when the jetting water for dissolving the cleaning agent hits the cleaning agent. This promotes the penetration of water, thereby causing the bleaching agent incorporated in the detergent to be gradually decomposed.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is intended to solve the problem. In a cartridge cleaning agent containing a bleaching agent, water permeation into the cleaning agent is reduced. Accordingly, an object of the present invention is to provide a cartridge cleaning agent and a method for producing the same, in which the decomposition of the bleach in the cleaning agent is suppressed.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies on the above-mentioned conventional problems, and as a result, it has been found that by mixing a nonionic surfactant having a specific viscosity with a detergent component, the particles are superior to each other. Suppressing the fluidity between the particles by providing an adhesive force, and further, after storing the detergent component in the cartridge, the powdery and granular detergent composition in the container is subjected to compaction filling treatment to remove the voids between the particles. The inventors have found that by reducing the amount, the penetration of water into the cleaning agent is significantly reduced, thereby suppressing the decomposition of the bleaching agent, thereby completing the present invention. That is, the cartridge cleaning agent of the present invention and the method for producing the same are in the following (1) and (2). (1) A cartridge detergent in which a granular detergent composition is stored in a container having an open mouth, wherein the particulate detergent composition contains at least the following components (A) and (B) And the powder composition is compacted and filled. (A) 0.1 to 5% by weight of a solid effective chlorine release source (B) 0.1 to 10% by weight of a nonionic surfactant having a viscosity of 40 to 1000 cps at 25 ° C. (2) At least the following components (A) and (B) A method for producing a cartridge cleaning agent, comprising storing a granular cleaning composition containing a component in a container having an open port, and then subjecting the granular cleaning composition in the container to compaction filling. . (A) 0.1 to 5% by weight of a solid available chlorine release source (B) 0.1 to 10% by weight of a nonionic surfactant having a viscosity of 40 to 1000 cps at 25 ° C.

[0008]

Embodiments of the present invention will be described below in detail. The cartridge cleaning agent of the present invention is a cartridge cleaning agent in which a granular cleaning composition is contained in a container having an open port, wherein the granular cleaning composition comprises at least the following components (A) and (B): The powdery and granular composition is compacted and filled. (A) 0.1 to 5% by weight of a solid available chlorine release source (B) 0.1 to 10% by weight of a nonionic surfactant having a viscosity of 40 to 1000 cps at 25 ° C.

The solid effective chlorine releasing source serving as the component (A) used in the present invention is used as a bleaching agent, and specifically includes sodium dichloroisocyanurate, trichloroisocyanuric acid, potassium dichloroisocyanurate and the like. Chlorinated isocyanuric acid compound, calcium hypochlorite trihydrate, 1-bromo-3-chloro-5,5-dimethylhydantoin, and the like. Particularly preferred are chlorinated isocyanuric acid compounds. The amount of the solid available chlorine release source is 0.1 to 5 with respect to the total amount of the composition.
%, Preferably 0.3 to 3.0% by weight. When the compounding amount of the solid effective chlorine releasing source is less than 0.1% by weight, the bleaching effect cannot be sufficiently obtained, and
If it exceeds 5% by weight, there is no significant difference in the effect, which is not preferable in terms of cost.

The nonionic surfactant used as the component (B) in the present invention has a viscosity at 25 ° C. of 40 to 1,000.
It needs to be cps. By using a nonionic surfactant having this viscosity range, the adhesive effect between particles in the cleaning agent can be improved and the desired effect can be achieved. When the viscosity of the nonionic surfactant is less than 40 cps, the adhesion between the particles becomes weak, and the viscosity becomes less than 1,000.
If it exceeds 0 cps, the viscosity is high, which is not preferable in production. Further, in the present invention, since the object is to provide a cartridge cleaning agent suitable for a dishwasher or the like, foaming of the cleaning liquid is very undesirable. Therefore, a nonionic surfactant having a foam suppressing effect is selected from various surfactants, and the viscosity range of the nonionic surfactant is set to the above range.

The nonionic surfactant is not particularly limited as long as it has the above viscosity range. For example, a polyoxyethylene polyoxypropylene block represented by the following general formula (I) or (II): Copolymers and polyoxyethylene polyoxypropylene adducts of ethylenediamine, and the like, and preferably represented by the general formula (I)
And (II) wherein R ₁ is an oxypropylene group and R ₂ is an oxyethylene group. The amount of the nonionic surfactant is 0.1 to 10% by weight, preferably 0.5 to 3.0% by weight, based on the total amount of the composition. If the amount of the nonionic surfactant is less than 0.1% by weight, the adhesive effect is insufficient, and if it exceeds 10% by weight, there is no significant difference in the effect, which is not preferable in terms of cost.

The detergent composition used in the present invention may further contain an alkali agent. Specific examples of the alkali agent include alkali metal hydroxides such as sodium hydroxide and potassium hydroxide, silicates such as sodium orthosilicate and sodium metasilicate, and carbonates such as sodium carbonate and potassium carbonate. Can be. Preferably,
These are alkali metal hydroxide salts such as sodium hydroxide and potassium hydroxide. The amount of the alkali agent is 10 to 60% by weight, preferably 20 to 50% by weight, based on the total amount of the composition. If the blending amount of the alkali agent is less than 10% by weight, the detergency is insufficient, and if it exceeds 60% by weight, erosion to tableware and the like becomes severe, which is not preferable.

The detergent composition used in the present invention may further contain optional components other than the above components, for example, a chelating agent, a hydration-solidifying auxiliary such as sodium sulfate, an oxidizing agent, an enzyme, a dye,
Flavors and the like can be blended. As chelating agents,
Specifically, hydroxycarboxylates such as sodium malate and sodium citrate, trisodium nitrilotriacetate, tetrasodium ethylenediaminetetraacetate, trisodium hydroxyethylenediaminotriacetate, pentasodium diethylenetriaminopentaacetate, triethylenetetraaminohexa Aminoacetates such as hexasodium acetate; condensed phosphates such as potassium pyrophosphate, sodium pyrophosphate and sodium tripolyphosphate; polyacrylic acid or copolymers obtained from monomers copolymerizable therewith, or water-soluble salts thereof, maleic acid Alternatively, a polymer chelating agent such as a homopolymer of maleic anhydride, a copolymer obtained from a monomer copolymerizable therewith, or a water-soluble salt thereof, and the like can be given.

In the present invention, it is desirable that the average particle size of each of the powdery and granular components in the above components is 5 mm or less, more preferably 1 mm or less. Average particle size of each component is 5mm
If there is a particle larger than the particle size, the adhesion between particles is reduced, so that water easily penetrates. In addition, the average particle size of the granular detergent composition is 0.0
It is desirable that the thickness be 1 mm to 5 mm, more preferably 0.05 mm to 1 mm. Large particles having an average particle size exceeding 5 mm are not preferred for the same reason as described above. On the other hand, if the average particle size is less than 0.01 mm, the solubility is poor and a required amount of the cleaning agent may not be supplied in a short time. As a method for preparing the powdery and granular detergent composition having the average particle size, for example, a powdery or granular component having an average particle size of more than 5 mm is not used, and It is desirable to use something like this. It is desirable that after the component (A) and the alkali agent are sufficiently mixed in advance, the component (B) is blended and stored in a container in a state of being dispersed and mixed as uniformly as possible.

The cleaning agent for a cartridge according to the present invention contains a powdery / granular cleaning composition having the above constitution in a container having an opening, and has a packing density of 1.0 to 2.0 g / cm ³ , preferably 1 to 2.0 g / cm ³ . It is prepared by compacting and filling to a density of 0.3 to 1.7 g / cm ³ . After the consolidation, it is preferable to seal the opening with a sealant. As a method of compacting the granular detergent composition so as to be in the range of the packing density, when filling the granular detergent composition into a container, vibration is applied to the side or bottom of the container by a machine or a hand. Can be consolidated
Furthermore, the cleaning agent contained in the container can be pressed and filled by using a stick or the like. When the packing density is less than 1.0 g / cm ³ , the adhesive effect is weakened due to insufficient compaction.
If it exceeds g / cm ³ , the solubility may be poor and a required amount of the cleaning agent may not be supplied in a short time.

Further, in the present invention, the sealing agent for covering the composition surface layer to be the surface of the container after the above-mentioned composition is compacted and filled in a container having an opening is provided with the following conditions. Sealant. From the manufacturing point of view, the sealant should not mix with the detergent powder previously filled. Also, after filling the sealant, it has been completely solidified all day and night. Under these conditions, the sealant is readily dissolved in water or the like under the use conditions. There is no particular limitation as long as the sealant satisfies these three conditions. For example, sodium tripolyphosphate, sodium orthosilicate, or the like can be used as the sealant. As an example, it can be carried out by preparing a slurry-like sealing agent composed of sodium tripolyphosphate and water, introducing the sealing agent into a composition surface layer compacted and filled in a container, and allowing it to solidify. By covering the surface of the cleaning agent with this sealant, scattering of the powder and granules from the container can be prevented, which is preferable in terms of operator safety. In addition, the cartridge cleaning agent of the present invention prepares a granular cleaning composition which has been compacted in advance in another mold in the same manner as described above or a granular cleaning composition which has a surface layer sealed with a sealing agent. Thereafter, the composition may be stored in a container having an opening.

The cartridge cleaning agent of the present invention can be produced by the above-mentioned method, and a mode of using the cleaning agent in an automatic cleaning machine will be described below with reference to FIG. FIG. 1 is a sectional view showing a configuration example of a cartridge cleaning agent suitable for an automatic cleaning machine of the present invention. In the cartridge cleaning agent according to the present invention, a cleaning agent 3 having a sealing agent 6 is housed in a container 1 having an opening 2 by compaction filling. The cartridge cleaning agent is set upside down in the feeder 5 and is used by sequentially dissolving the cleaning agent 2 while spraying water from the nozzle 4. In the cartridge detergent of the present invention configured and used as described above, by adding the component (B) to the mixture such as the component (A), the adhesive force between the detergent particles is improved, and the detergent is further used. After being housed in the cartridge, the gap between the cleaning particles can be reduced by, for example, compacting and filling the cleaning composition in the container. As a result, in the present invention,
The bleaching agent does not decompose even under long-term use conditions in which water is applied, and can maintain an excellent bleaching effect.
