Description

Method for producing gel-like detergent
The present application is a divisional application of chinese patent application 201380081777.9(PCT application No. PCT/JP2013/084366) having an application date of 2013, 12 and 20 months, and having an inventive name of "method for producing gel-like detergent".
Technical Field
The present invention relates to a method for producing a gel-like detergent.
Background
Generally, detergents are classified by appearance and are well known to be classified as solids, liquids and gels. Among these detergents, gel-like detergents have high commercial value and wide market prospects because they give a unique tactile sensation.
As a method for producing a gel-like detergent, there are known a method including: first, a process of mixing components such as a detergent composition and a gelling agent; then, a process of heating and stirring the mixture to obtain a gel-like substance; finally, the gel-like material is poured into a mold for molding and hardened.
For example, patent document 1 discloses a cleaning agent in the form of a gel-like semisolid prepared from an anionic surfactant, an amphoteric surfactant, and a gelling agent derived from a natural source, in which a casting mold is used as a mold for molding. However, since the gel-like detergent is a substance having a high moisture content and the gelling agent is easily mildewed and deteriorated, microorganisms such as bacteria are easily propagated, which makes it necessary to take time to clean the recycled casting mold. Further, since the desired gel-like cleansing agent has a different size, it is necessary to prepare a molding die having a desired size, which results in a very low production efficiency of the gel-like cleansing agent.
Patent document 2 discloses that a cylindrical container can be used as a mold for molding in a gel-like cleaning material prepared from a cleaning component and a polysaccharide, but does not disclose what kind of material the cylindrical container is made of.

Further, from the viewpoint of low irritation to the skin, stability in hard water, and excellent foaming power, alkylamidopropylbetaines shown in (B-6) are preferable. From the viewpoint of excellent detergency and foamability, and low irritation to the eye, 2-alkyl-N-carboxymethyl-N-hydroxyethyl imidazoline betaine is preferable.
The gelling agent may contain one or more than 2 kinds selected from group C shown below.
(group C) gelling agent
(C-1) Water-soluble Polymer derived from plant or seaweed
Xyloglucan, guar gum, locust bean gum, agarose, carrageenan, gum arabic, sodium alginate, glucomannan, pectin.
(C-2) Water-soluble Polymer derived from fermentation with microorganism
Xanthan gum, gellan gum, pullulan polysaccharide, curdlan, sodium hyaluronate.
From the viewpoint of low irritation to the skin, the gel-like detergent preferably has a pH of 8 or more and 11 or less in terms of a 1 wt% aqueous solution, and therefore the gelling agent is preferably alkali-resistant, salt-resistant, and heat-resistant. Among them, xyloglucan, guar gum, carrageenan and locust bean gum derived from tamarind gum are water-soluble polymers of gums having salt resistance and heat resistance, and they are derived from plants, and therefore they are preferable from the viewpoint of environmental protection.
The amount of the gelling agent is preferably 0.1 wt% to 10 wt%, more preferably 1 wt% to 5 wt%, based on the total weight of the gel-like cleansing agent. When the amount of the gelling agent is less than 1% by weight, solidification to form a gel is difficult, while when the amount of the gelling agent exceeds 10% by weight, excessive solidification occurs, whereby the foamability of the gel-like cleansing agent is impaired, foaming is not easily generated during use, and detergency cannot be exerted.
A1 wt% aqueous solution of a gelling agent having a viscosity of 5 to 9000 mPas, more preferably 1000 to 8000 mPas, and still more preferably 2000 to 6000 mPas is preferably used. When the viscosity is less than 5 mPas or exceeds 9000 mPas, handling becomes difficult.
The gel-like detergent preferably contains one or more types of monohydric alcohol or polyhydric alcohol from the viewpoint of improving foamability, foam quality, and moisture retention of the skin, and also from the viewpoint of thickening by interaction with a gelling agent such as a water-soluble polymer.

The amount of the saccharide or sugar alcohol is preferably 0.5 wt% to 50 wt%, more preferably 3 wt% to 30 wt%, based on the total weight of the gel-like detergent.
Fig. 1 is a flowchart illustrating a process for carrying out a method for producing a gel-like detergent according to a first embodiment of the present invention. The first embodiment of the present invention is carried out by the process (a) of heating a gelling agent in water to 70 ℃ to 85 ℃ inclusive to dissolve the gelling agent, thereby obtaining a gelled aqueous solution (step S1); a process (B) of adding the detergent composition to the gelling aqueous solution and then dispersing the mixture to obtain a dissolved mixture (step S2); then, a process (C) of stirring the dissolved mixture and filling it into a rubber-like container for molding (step S3); a step (D) of cooling and hardening the dissolved mixture filled in the rubber-like container at room temperature (step S4); and (E) a step of removing the rubber-like container (step S5).
In step S1, the gelling agent is dissolved in water by heating at 70 to 85 ℃, thereby obtaining a gelling aqueous solution. The gelling aqueous solution is obtained by heating at 70 ℃ to 85 ℃ for a predetermined time (for example, 15 minutes to 3 hours) to swell the gelling agent, and mixing or dissolving the gelling agent in water. FIG. 5 is a schematic cross-sectional view of one example of a fluid reservoir tank for use in practicing the manufacturing method of the present invention. For example, a gelling agent and water are added to a liquid storage tank 10 having a heater 11 as shown in fig. 5. Then, the stirring device 12 having a stirring blade or the like in the stock solution tank 10 is operated to stir the gelled aqueous solution 13 in the stock solution tank, thereby uniformly mixing the gelled aqueous solution. If the heating temperature is less than 70 ℃, the gelling agent may be incompletely dissolved, while if the heating temperature exceeds 85 ℃, the gelling agent may be denatured.
When a monohydric or polyhydric alcohol is added to the gel-like cleansing agent, in step S1, the monohydric or polyhydric alcohol is added, and the gelling agent and water are heated and dissolved together at 70 ℃ to 85 ℃ to obtain a gelled aqueous solution.
In step S2, the detergent composition is added to the gelling aqueous solution and dispersed to obtain a dissolved mixture. In order to uniformly disperse the detergent composition in the gelling aqueous solution, it is preferable to heat and disperse the detergent composition for a predetermined time (for example, 1 hour to 2 hours). The heating temperature may be appropriately set according to the melting point of the gelling agent and the detergent composition. In general, the heating temperature is preferably not lower than the melting point of the highest melting temperature of the raw material, and is preferably 65 ℃ or higher and not higher than 85 ℃ in order to prevent the gelling agent from being denatured while dissolving the raw material.
In order to prevent the mixing of bubbles generated by the addition of the detergent composition and to improve the transparency of the gel-like detergent, it is preferable to degas the dissolved mixture using a vacuum vessel. Fig. 2 is a flowchart illustrating a process for carrying out the method for producing a gel-like detergent according to the second embodiment of the present invention, which is a process (B) for obtaining a dissolved mixture by adding a detergent composition to a gelled aqueous solution and then dispersing the same, and a process (G) for obtaining a dissolved mixture by adding a detergent composition to a gelled aqueous solution and then dispersing the same, and degassing the same (step S2-1). Fig. 6 is a schematic cross-sectional view showing an example of a vacuum apparatus for carrying out the manufacturing method of the present invention. In step S2-1, the gelled aqueous solution and the detergent composition are charged into the vacuum tank 21, the above substances are heated and stirred in the vacuum apparatus 20 by operating the stirring device 22 of the vacuum apparatus having a stirring blade or the like and the jacket 24 having a heating device in the vacuum apparatus 20, the pressure in the vacuum tank 21 is reduced or brought into a vacuum state by operating the vacuum pump 23, the dissolved mixture is uniformly mixed, and bubbles are removed. In order to remove the deposits on the inner wall surface of the vacuum vessel 21 or the residues in the lower part of the vacuum vessel 21, the stirring device 22 of the vacuum apparatus is preferably an anchor stirrer equipped with a scraper 25. In order to mix the dissolved mixture having high viscosity, it is preferable that the stirring device 22 of the vacuum device is a device capable of obtaining a peripheral speed of 5 m/sec to 25 m/sec. From the viewpoint of efficiency of bubble removal, it is preferable that the degree of vacuum in the vacuum apparatus 20 is 15kpa (abs) or less and 75kpa (abs) or less. In the case where the detergent composition is dispersed after being added to the gelling aqueous solution, and the process for obtaining the dissolved mixture and the degassing process are simultaneously performed in the vacuum apparatus 20, the treatment time is preferably 1 hour to 1.5 hours in order to prevent the water content in the dissolved mixture from decreasing, and the process is preferably performed in stages during heating.
Fig. 3 is a flowchart illustrating a process for carrying out a method for producing a gel-like detergent according to a third embodiment of the present invention, and the process (B) for obtaining a dissolved mixture by adding a detergent composition to a gelled aqueous solution and dispersing and degassing the mixture includes a process (H) for obtaining a preparation by adding a potassium salt of a fatty acid to the gelled aqueous solution and dispersing and degassing the mixture (step S2-2), and a process (I) for obtaining a dissolved mixture by adding a detergent composition other than the potassium salt of a fatty acid to the preparation and dispersing and degassing the mixture (step S2-3). In the case where the gel-like detergent contains a potassium salt of a fatty acid, since it is difficult to remove air bubbles, it is preferable to perform the steps S2-2 and S2-3 to perform degassing twice when obtaining a mixture after dissolution from the aqueous gelation solution.
The gelled detergent of the present invention may contain other components, for example, preservatives (ethyl p-hydroxybenzoate, butyl p-hydroxybenzoate, etc.), powders (pigments, dyes, resins, etc.), perfumes, moisturizers, physiologically active ingredients, salts, solvents, pearlizing agents, neutralizers, pH adjusters, enzymes, etc., as appropriate, in addition to the gelling agent and the detergent composition, within a range not detrimental to the object of the present invention. From the viewpoint of dispersibility of each component, those components are preferably compatible with a dissolved mixture in which the detergent composition is not sufficiently dissolved in the gelling aqueous solution, and for example, when a gold foil is contained in the gel-like detergent, the gold foil dispersed in an alcohol solvent is added to the dissolved mixture and mixed to be dispersed.
In step S3, the dissolved mixture is stirred and filled into a rubber-like container for molding. FIG. 7A is a view showing a process of filling the dissolved mixture of the present invention into a rubber-like container for molding. Fig. 7B is an enlarged view of the filling process.
A plurality of notches 2, an injection portion 3, and a removal portion 4 are provided at equal intervals on the outer peripheral portion of the turntable 1 of the filling device 40. When the rubber-like container 41 is in the attached state, the turntable 1 intermittently rotates. A rubber-like container 41 is attached to the notch 2 located in front of the injection portion 3. In the injection section 3, when the turntable 1 is stopped, the injector 3a is lowered to be in close contact with the upper portion of the rubber-like container 41, and a predetermined amount of the dissolved mixture is filled in the rubber-like container 41. Further, when the injector 3a is raised in the above-mentioned filled state, since the dissolved mixture overflows from the rubber-like container, the injector 3a is raised after the opening 41a is bound with the binding material 41c by the binding device 3b provided on the outer peripheral portion of the rotary table 1. Further, the rubber-like container 41 filled with the dissolved mixture therein is rotated and removed from the notch portion in the removing portion 4.
As shown in fig. 7B, the rubber-like container 41 has an opening 41a for filling the dissolved mixture and an expandable expansion portion 41B formed in a substantially spherical or elliptical shape. The material of the rubber-like container 41 may be, for example, natural latex or synthetic latex, and is not particularly limited as long as it is a material used in a usual case. Since the rubber-like container 41 has a colored or transferable pattern on the inside thereof, the color can be maintained inGelThe outside of the detergent-like body is colored or patterned. The filling amount of the mixture after dissolution is not particularly limited, and for example, the filling amount may be set to 100g so that the rubber-like container swells to form a substantially spherical shape having a diameter of 5 cm.
Fig. 4 is a flowchart illustrating a process for carrying out a method for producing a gel-like cleansing agent according to a fourth embodiment of the present invention. Between the process (C) and the process (D), it is further preferable to include a process (F) of removing the remaining dissolved mixture by suction from the opening of the rubber-like container (step S3-2). When step S3-2 is performed, for example, it is preferable that the removing unit 4 of the filling device 40 is provided with a suction device 4a for sucking and removing the remaining dissolved mixture flowing out of the rubber-like container 41 from the opening 41a of the rubber-like container. The suction pump 4b of the suction device 4a sucks the gas in the suction nozzle 4c to recover the remaining dissolved mixture, and at the same time, the rubber-like container 41 can be removed from the notch 2 by the suction pressure.
FIG. 7C is a sectional view showing an example of a filling apparatus for filling a rubber-like container for molding with the dissolved mixture, for carrying out the production process of the present invention. The filling device 40 is a device that raises or lowers the injectors 3a each by means of a cylindrical cam. A plunger 5 is slidably attached to a center portion of the injector 3a, the injector 3a is vertically moved by an injector drive cam 7, and the plunger 5 is vertically moved by a plunger drive cam 6. When the turntable 1 is stopped, the injector 3a is driven by the injector drive cam 7 to descend and contact the upper surface of the turntable 1, and then the plunger 5 is pushed downward by the plunger drive cam 6. On the upper part of the filling device 40, a liquid reservoir 8 of the filling device is installed, and the inside thereof is filled with the dissolved mixture to be filled. In the stage where the plunger 5 is moved up, the dissolved mixture flows from the reservoir tank 8 of the filling device with stirring function into the injector 3a through the pipe 9, and is filled into the rubber-like container 41 by the downward movement of the plunger 5. The cam shaft 47 to which each cam is attached is driven by the motor 42 via the chain 43, and the turntable 1 is driven by the motor 42 and rotated via the chain 44, the intermittent drive unit 45, and the chain 46.
From the viewpoint of filling properties, it is preferable to cool the dissolved mixture to 60 ℃ to 65 ℃. When the temperature is lower than 60 ℃, the dissolved mixture is easily hardened, and the filling property into the rubber-like container is deteriorated, while when the temperature exceeds 65 ℃, the viscosity of the dissolved mixture is lowered, and the weight of the gel-like detergent may be uneven during filling. In the process (C) of filling the dissolved mixture into a rubber-like container for molding, the filling rate is preferably 33 g/sec or more and 50 g/sec or less. When the filling rate is less than 33 g/sec, the mixture after dissolution is easily hardened, while when the filling rate is more than 50 g/sec, air may be mixed into the rubber-like container 41.
In step S4, the dissolved mixture filled in the rubber-like container 41 is cooled and hardened at room temperature. FIG. 8 is a schematic view showing an example of an apparatus for cooling and hardening a dissolved mixture filled in a rubber-like container for molding, for carrying out the production method of the present invention. The dissolved mixture filled in the rubber-like container 41 is stored in the holder 51 with the bundled mouth portion 41a facing downward, placed in the storage box 50, and left to stand at room temperature. By setting the time required for cooling and hardening to a time of about 1 day to 2 days, the mixture dissolved in the rubber-like container 41 is hardened to the center to form a gel-like detergent.
In step S5, the rubber-like container is removed. FIG. 9 is a view showing a process (E) for removing the rubber-like container of the present invention. The rubber-like container 41 is broken by a sharp-pointed instrument 61 such as a needle to remove the rubber-like container 41, and the gel-like detergent 62 is taken out from the rubber-like container 41. Since the rubber-like container 41 is formed into a substantially elliptical spherical shape by being swollen by filling the gel-like detergent 62, the surface of the rubber-like container 41 can be broken by making a small hole, and thus the breakage easily occurs.
As shown in fig. 7B, the rubber-like container 41 preferably has a protrusion 41d on the side opposite to the opening 41 a. In step S5, when the rubber-like container 41 is broken, the broken rubber film instantaneously contracts, and therefore the external shape of the gel-like detergent 62 may be damaged. However, when the rubber-like container 41 has the protrusions 41d, the rubber film can be smoothly contracted as compared with a rubber-like container without the protrusions 41d, and therefore the rubber-like container 41 can be broken without breaking the outer shape of the gel-like detergent 62.
