Description

Manufacturing method of gel-like cleaning material {METHOD FOR PRODUCING GEL DETERGENT}

TECHNICAL FIELD This invention relates to the manufacturing method of a gel-like cleaning material.

Conventionally, cleaning agents are known to be divided into solid, liquid and gel phases as apparent classifications. Among them, the gel detergent has a unique texture to the user and has a high product value and marketability.

The method for producing a gel detergent includes a step of mixing components such as a detergent composition, a gelling agent, a step of stirring while heating the mixture to obtain a gel, and a step of pouring the gel into a mold for solidification. It is known.

For example, Patent Document 1 uses a mold as a mold for molding in a gel-like or semi-solid cleaning material in which an anionic surfactant, an amphoteric surfactant, and a natural gelling agent are blended. However, the gel detergent has a high moisture content, and the gelling agent tends to decay. Therefore, microorganisms such as bacteria tend to propagate, and time is required for washing the reused mold. In addition, since the mold for shaping | molding must be prepared for every desired size of gel-like cleaning material, production of a gel-like cleaning material was inefficient.

Patent Document 2 discloses the use of a cylinder as a mold for molding in a gel-like cleaning material in which a cleaning component and a polysaccharide are blended. However, it is not disclosed in what material the container is formed.

According to a first embodiment of the present invention, the gelling agent is heated and dissolved in water at 70 ° C. or higher and 85 ° C. or lower to obtain a gelling aqueous solution (A) (step S1), and the detergent composition is added and dispersed in the gelling aqueous solution to dissolve the melt. Obtaining step (B) (step S2), step (C) of filling the melted rubber container with stirring (step S3), step (D) of cooling and solidifying the melt filled in the rubber container at room temperature (step) S4), it is performed by performing the process (E) (step S5) of removing a rubbery container.

In step S1, the gelling agent is dissolved in water at 70 ° C. or higher and 85 ° C. or lower to obtain a gelling aqueous solution. The gelling aqueous solution is obtained by heating the gelling agent at a temperature of 70 ° C. or more and 85 ° C. or less for a predetermined time (eg, 15 minutes or more and less than 3 hours), swelling, mixing with the water, and dissolving it. It is a schematic cross section which shows an example of the tank for implementing the manufacturing method of this invention. The gelling agent and water are prepared in the tank 10 provided with the heater 11 shown, for example in FIG. And the inside of the tank 10 is stirred, and the gelation aqueous solution 13 is mixed uniformly by operating the stirring means 12, such as the stirring blade provided in the tank 10 inside. If the heating temperature is less than 70 ° C., the gelling agent may be incompletely dissolved. On the other hand, if the heating temperature is higher than 85 ° C., the gelling agent may be denatured.

 In addition, when a gel detergent contains monohydric or polyhydric alcohol, in step S1, monohydric or polyhydric alcohol is added and it heat-dissolves at 70 degreeC or more and 85 degrees C or less with a gelling agent and water, and obtains a gelling aqueous solution.

 In step S2, the detergent composition is added and dispersed in the gelling aqueous solution to obtain a melt. It is preferable to carry out while heating the predetermined time (for example, 1 hour or more and 2 hours or less) so that a cleaning composition may be disperse | distributed uniformly in the gelling agent aqueous solution. Heating temperature can be suitably set according to melting | fusing point of a gelling agent and detergent composition. Generally, it is preferable that heating temperature is more than melting | fusing point of the raw material which has the highest melting | fusing point, and it is preferable that it is 65 degreeC or more and 85 degrees C or less in order to make the dissolution of a raw material and prevention of denaturation of a gelling agent.

In order to prevent mixing of bubbles generated by the addition of the cleaning composition and to improve the transparency of the gel-like cleaning agent, it is preferable to degas the melt using a vacuum apparatus. FIG. 2 is a flowchart for explaining a step for carrying out the method for producing a gel detergent according to a second embodiment of the present invention, in which the detergent composition is added and dispersed in a gelling aqueous solution to obtain a melt, It is set as the process (G) (step S2-1) which obtains a melt, adding and disperse | distributing a detergent composition to gelling aqueous solution and degassing. FIG. 6: is a schematic cross section which shows an example of the vacuum apparatus for implementing the manufacturing method of this invention. In step S2-1, the gelling aqueous solution and the cleaning composition are put in a vacuum kiln (pot) 21, and the jacket provided with the stirring means 22 and the heating means of a vacuum apparatus such as a stirring blade provided in the vacuum apparatus 20.

It is set as process (I) (step S2-3) which obtains a melt while making it melt. In the case where the fatty acid potassium salt is contained in the gel-like detergent, since bubbles are difficult to remove, it is preferable to perform step S2-2 and step S2-3 and degas twice when obtaining a melt from the gelling aqueous solution.

In addition to the gelling agent and the cleaning composition, the gel detergent of the present invention may contain other components, such as preservatives (ethyl paraben, butyl paraben, etc.), powder (pigments, dyes, resins, etc.) in a range that does not impair the object of the present invention.

It is preferable to mix | blend these components with the melt | dissolution which the detergent composition melt | dissolved in the gelling aqueous solution from the viewpoint of the dispersibility of each component. For example, when gold leaf is contained in a gel detergent, the gold leaf disperse | distributed to the alcohol solvent is added to a melt, it mixes, and it disperse | distributes.

In step S3, the melt is filled into a molding rubbery container with stirring. FIG. 7A is a diagram showing a step (C) of filling the melted rubber container of the present invention into a molding rubber container, and FIG. 7B is an enlarged view of the filling step (C).

The notch part 2 is formed in multiple numbers by the same pitch in the outer peripheral part of the rotating table 1 of the charging device 40, and the injection part 3 and the separating part 4 are provided. In the state where the rubber-like container 41 is mounted, the turntable 1 rotates intermittently. In the notch part 2 in front of the injection part 3, the rubber-like container 41 is attached. In the injection part 3, the injector 3a descend | falls at the stage in which the rotary table 1 stopped, and it adheres to the upper surface of the rubber container 41, and the fixed amount of melt is filled in the rubber container 41. As shown in FIG. . If the injector 3a rises as it is, the opening 41a is bound by the binding device 3b attached to the outer periphery of the rotary table 1 because the melter overflows from the rubber container 41. After being bound by the member 41c, the injector 3a is raised. The rubber container 41 filled with the melt therein is further rotated and separated from the notch part 2 in the separating part 4.

As shown in FIG. 7B, the rubber-like container 41 has an opening portion 41a for filling the melt and an expansion portion 41b that extends into a substantially spherical or substantially ellipsoidal shape. The material of the rubber-like container 41 is not particularly limited as long as it is generally used, for example, natural latex or synthetic latex. By having the shape which can be colored or transferred inside the rubber-like container 41, coloring or a shape can be given to the outer side of a rubbery detergent. In addition, the filling amount of the melt is not particularly limited, but, for example, by setting the filling amount to 100 g, the rubber container is expanded to a substantially spherical shape having a diameter of 5 cm.

4 is a flowchart for explaining a step for carrying out the method for producing a gel detergent according to the fourth embodiment of the present invention. It is preferable to further include the process (F) (step S3-2) which removes the said melt | dissolution by suction from the opening part of a rubber-like container between process (C) and process (D). In the case of performing step S3-2, for example, in the separating part 4 of the filling device 40, the residual melt which escaped from the rubber container 41 is suctioned off from the opening part 41a of the rubber container. It is preferable that the suction device 4a be provided. The suction pump 4b of the suction device 4a sucks the gas in the suction nozzle 4c to recover the residual melt and at the same time separate the rubber container 41 from the notch portion 2 by the suction pressure. You can (tear it off).

It is sectional drawing which shows an example of the filling apparatus which fills the rubber container for shaping | molding the melt for implementing the manufacturing method of this invention. The filling device 40 raises and lowers the injector 3a by the cylindrical cam. In the injector 3a, the flanger 5 is slidably mounted in the center thereof, the injector 3a is lifted by the injector drive cam 7, and the flanger 5 is the flanger drive cam 6. To get on and off. When the turntable 1 stops, the injector 3a is lowered by the injector drive cam 7 to contact the upper surface of the turntable 1, and the flanger 5 then rotates the flanger drive cam 6. Pressed down by). The tank 8 of the filling device is mounted on the top of the filling device 40, and the melt to be filled is filled. In the step in which the flanger 5 is raised, the melt flows into the injector 3a from the tank 8 of the filling device having a stirring function via the pipe 9, and the rubber phase is caused by the dropping of the flanger 5. It is filled in the container 41. Each cam-mounted camshaft 47 is driven by the motor 42 via the chain 43, and the rotary table 1 is driven from the motor 42 by the chain 44, the intermittent drive device 45 and Rotate through chain 46.

It is preferable to cool a melt to 60 degreeC or more and 65 degrees C or less from a filling point. If it is less than 60 degreeC, melt will be easy to solidify, and the filling property to rubber-like container 41 will worsen. On the other hand, if it exceeds 65 degreeC, the viscosity of melt will become low and a difference (deviation) may arise in the weight of the gel detergent at the time of filling. There is concern. Moreover, it is preferable to perform the process (C) of filling a melt | melt in the rubber container for shaping | molding at the filling speed of 33 g or more and 50 g or less per second. If it is less than 33 g per second, a melt will be easy to solidify, and if it exceeds 50 g per second, there exists a possibility that air may mix in the rubber-like container 41.

In step S4, the melt filled in the rubber container 41 is cooled and solidified at room temperature. 8 is a schematic view showing an example of an apparatus for cooling and solidifying a melt filled in a rubber-like container 41 for molding for carrying out the production method of the present invention. The melt filled in the rubber-like container 41 is stored in the holder 51 so that the bound opening part 41a is lowered, and left still at room temperature with the storage box 50. When the time for cooling solidification is about 1 day or more and 2 days or less, the melt filled in the rubber container 41 solidifies to the center part and becomes a gel detergent.

In step S5, the rubber container is removed. It is a figure which shows the process (E) of removing the rubbery container of this invention. By rupturing the rubber container 41 by a mechanism 61 having a tip such as a needle, the rubber container 41 is removed and the gel detergent 62 in the rubber container 41 is taken out. . Since the rubber container 41 is expanded in a substantially spherical shape or an approximately elliptic shape by the filling of the gel cleaning agent 62, by generating a small hole, the surface of the rubber container 41 has a flaw and easily ruptures. Done.

As shown in FIG. 7B, the rubber container 41 preferably has the protrusion 41d on the opposite side of the opening 41a. When the rubbery container 41 ruptures in step S5, the torn rubber film is about to shrink at once, which may damage the appearance of the gel-like cleaner 62. However, if the rubber-like container 41 has the protrusion 41d, the rubber film is reduced softly (softly) as compared with the absence of the protrusion 41d, so that the rubber-like cleaning agent 62 does not damage the appearance of the gel-like cleaner 62. The container 41 can be ruptured.
