Description

Manufacturing method of foam sheet-type cleaning products and portable cleaning products using the same

The present invention relates to a method of manufacturing a foam sheet type cleaning product and a portable cleaning product using the same, and more particularly, by homogenizing a viscous composition for maintaining the foam sheet shape and a liquid cleaning component to form microbubbles and then freeze-drying, It is possible to provide a foam sheet-type cleaning product having an open cell structure, and due to the foam form, water is quickly absorbed by capillary action at the moment of contact with water, and hydration is fast due to the expansion of the surface area, so that the shampoo function is activated more quickly It relates to a method for manufacturing a foam sheet type cleaning product that can be used without any significant difference from a liquid type shampoo, is portable, and is convenient to use immediately in the field, and a portable cleaning product using the same.

In the industrial society, as the necessity of washing hair or face becomes important due to dust and external stimuli caused by various pollution, various cleaning products are being released.

In particular, in general, shampoo is stored in a liquid state in a plastic container, and the components of the shampoo are composed of a cleaning component and most of water.

Therefore, there are many inconveniences to carry while traveling. In particular, liquid shampoo products are regulated when traveling by air, so you may pay unwanted expenses in terms of volume and weight.

In order to solve this inconvenience, shampoos that are easy to carry have been proposed in various forms such as films, capsules, and sheet types, from products in which small amounts are divided into small containers.

Patent Document 1 discloses a film-type soap or detergent that dissolves quickly in water by adding a surfactant and a plasticizer to a water-soluble polymer. However, in the case of a water-soluble film such as polyvinyl alcohol, it has hygroscopic properties, so There is a problem in that the film is damaged without being able to maintain the original shape of the film by absorbing the film, sticking to each other and softening.

In order to improve this problem, in the case of a detergent pouch product, in Patent Document 2, an outer layer material made of a water-insoluble or water-dispersible sheet material (for example, a non-woven fabric) and a product made from a water-soluble film (for example, polyethylene oxide) reported. However, in the case of the above product, there is a problem that there is no stickiness and is stable under a high humidity condition, but the outer layer material that has not been dissolved after use must be recovered from the laundry, that is, there is a residual material.

Therefore, the film-type soap is convenient for portability and can be used as a detergent of an aesthetically luxurious formulation, but due to the above-described drawbacks, it is not widely used in daily life.

Patent Document 3 is an invention related to a sheet-type shampoo by inserting a sheet composed of nonwoven fabric or pulp so as to keep the contents in their original state and to wipe hair or body in a pouch that prevents foreign substances from penetrating, and washes the hair or body in the sheet. It is reported that by filling and configuring the shampoo composition, water is not required separately and can be washed by wiping the hair or body.

Although the manufacturing process of the above sheet-type shampoo is simple, there is a problem in that the artificially synthesized auxiliary sheet is finally discharged as waste that is environmentally difficult to decompose.

The above film-type shampoo or soap has been improved by introducing an anti-seize agent in order to maintain the strength of the film and to improve the feeling of residue due to excessive shampoo function and separate components or to improve the aggregation phenomenon due to self-adhesion, but artificially synthesized It is a high molecular material and contains a large amount of components that are difficult to decompose in the environment.

On the other hand, capsule-type shampoo requires a delayed time for the shampoo to be hydrated and cleaned by going through the dissolution process of the capsule, and both require a heat-drying process.

In addition, as a method for manufacturing a foam sheet, a method for manufacturing using a foaming agent, a method through a chemical reaction, and the like are known.

However, the former method requires a high temperature, which may lead to deterioration of the shampoo, and also residues of the foaming agent may remain and unwanted impurities may remain and cause toxicity. In the latter case, it is a method of foaming using a gas generated through a chemical reaction, but it is an unsuitable method for water-based type.

Accordingly, the present inventors have intensively researched the mixing ratio of the shampoo composition having the ingredients and functionality for maintaining the form of the foam sheet and the method of forming the foam in order to solve the problems of the prior art, and as a result, a synthetic or animal-derived water-soluble polymer Excluding use, homogenizing the viscous composition for maintaining the form of a foam sheet containing water-soluble polymers derived from plants and liquid cleaning ingredients to form micro-bubbles and then freeze-drying, makes foam formation easy and requires no heat, especially The present invention was completed by providing a foam sheet-type cleaning product having an open cell structure without altering the ingredients contained in the shampoo, and confirming excellent solubility and cleaning properties when the cleaning product comes into contact with water.

In the above, it is preferable to use any one selected from liquid shampoo and liquid soap as the liquid cleaning component, and the liquid soap includes liquid for face washing, kitchen use, or laundry.

In the manufacturing method of the manufacturing method of the foam sheet type cleaning product of the present invention, the molding is performed by putting the mold in a thickness of 1 to 5 mm.

Furthermore, the present invention provides a portable foam sheet type having an open cell structure from a manufacturing method of a foam sheet type cleaning product. We provide cleaning products.

More specifically, it is possible to provide a foam sheet-type shampoo or soap product.

According to the method for manufacturing a foam sheet-type cleaning product having an open cell structure of the present invention, it has excellent compatibility in mixing with the conventional liquid cleaning component and the component, and homogenizes the viscous composition for maintaining the form of the foam sheet By freeze-drying after forming micro-bubbles, it is possible to easily form foam without requiring heat and without altering the components contained in the shampoo.

The foam sheet-type cleaning product of the present invention absorbs water quickly due to its foam form and is quickly hydrated due to the capillary phenomenon at the moment of contact with water. It is easy to carry and convenient to use immediately in the field.

Hereinafter, the present invention will be described in detail.

The present invention relates to 100 parts by weight of a raw material composition composed of 20 to 50% by weight of a water-soluble polymer and 50 to 80% by weight of a nonionic low molecular weight substance, 100 parts by weight of purified water is added and dissolved, and then the remaining components after subtracting moisture are recovered. Stage 1,

A second step of adding 20 to 40% by weight of the recovered non-volatile matter into a container, adding 60 to 80% by weight of a liquid cleaning component, and homogenizing to obtain a mixed solution containing microbubbles; and

It provides a method of manufacturing a foam sheet-type cleaning product having an open cell structure, comprising the third step of molding and freeze-drying by putting the prepared mixed solution into a molding mold.

In the manufacturing method of the foam sheet type cleaning product of the present invention, the first step is a step of preparing a viscous composition for maintaining the form of the foam sheet, and 20 to 50% by weight of a water-soluble polymer and 50 to 80% by weight of a nonionic low molecular weight material is made of

The water-soluble polymer used in the viscous composition for maintaining the form of the foam sheet in the present invention excludes known synthetic water-soluble polymer components such as polyacrylic acid, polyvinyl alcohol, polyvinylpyrrolidone, and polyacrylamide.

In addition, according to the report that water-soluble polymers derived from animals in the water-soluble polymer group can easily deteriorate during the manufacturing and storage process or act as a factor hindering the long-term storage of the manufactured shampoo, and can rarely cause allergic reactions in some people. It is not preferable as a water-soluble polymer of the present invention.

Therefore, the water-soluble polymer of the present invention is to use any one selected from the group consisting of a cellulose-based polymer, water-soluble collagen, soluble starch, sodium alginate, sodium hyaluronate, and fullulan. That is, by using a water-soluble polymer derived from a plant and processed, it is easy to decompose in a natural environment.

In the above, the cellulosic polymer includes methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxybutyl cellulose, and the like.

In the embodiment of the present invention, soluble starch or sodium alginate is used as a more preferred example of the water-soluble polymer, but the present invention is not limited thereto.

The nonionic, low molecular weight material, which is another component of the viscous composition for maintaining the form of the foam sheet of the present invention, has excellent compatibility with water-soluble polymers, should be easily soluble in water, and should be in a solid state at room temperature.

As a preferred example, any one selected from the group consisting of cyclodextrin, sucrose (sugar), salt (salt), erythritol, sodium L-glutamate and organic acid salts is used. In an embodiment of the present invention, sucrose is used as a more preferred example of the nonionic low molecular weight material, but the present invention will not be limited thereto.

The viscous composition for maintaining the form of the foam sheet of the present invention changes the degree of hydration in water according to the composition ratio of the above water-soluble polymer and nonionic low molecular weight material.

Specifically, if described based on an example selected in the embodiment of the present invention, in the case of soluble starch, which is a water-soluble polymer, when water is volatilized and dried, it solidifies to a very hard state, so it takes too long to hydrate and completely dissolve again. If it does not melt partially, it may give a feeling of foreign body.

On the other hand, low molecular weight sucrose proceeds very quickly until completely dissolved in water, so when sucrose is mixed with soluble starch and dried and then solidified, the time to dissolve in water is significantly improved compared to soluble starch alone. Finally, it is completely dissolved.

Accordingly, the viscous composition for maintaining the form of the foam sheet of the present invention is preferably mixed with 20 to 50% by weight of a water-soluble polymer and 50 to 80% by weight of a nonionic low molecular weight material, more preferably 30 to 45% by weight of a water-soluble polymer and 55 to 75% by weight of a nonionic low molecular weight substance, most preferably 35 to 40% by weight of a water-soluble polymer, and 60 to 65% by weight of a nonionic low molecular weight substance.

At this time, if the water-soluble polymer is less than 20% by weight, the sheet is formed, but the content of sucrose is relatively high, so that it is easily broken and the portability is rapidly reduced. There is a problem.

In the manufacturing method of the foam sheet type cleaning product of the present invention, in the second step, the liquid cleaning component mixed with the viscous composition for maintaining the form of the foam sheet has no compatibility problem in mixing with the component for maintaining the form of the foam sheet. , is not particularly limited, and commercially available products may be used.

From the manufacturing method of the foam sheet type cleaning product of the present invention, since the liquid cleaning component is provided as a foam sheet type cleaning product and can be used portable, the liquid cleaning component can be used in liquid shampoo or liquid soap as long as it meets the requirements. Any one selected may be applied. In the above, the liquid soap may include soap for face washing, kitchen use, and laundry.

According to an embodiment of the present invention, a foam sheet type shampoo can be prepared using a liquid shampoo, and excellent solubility and cleaning feeling can be confirmed.

In the second step, 20 to 40% by weight of the component (non-volatile matter) for maintaining the form of the foam sheet recovered in the first step is added to the container, and 60 to 80% by weight of the liquid cleaning component is added and homogenized to mix containing microbubbles A solution is obtained.

More preferably, 30 to 40% by weight of the component (non-volatile matter) for maintaining the form of the foam sheet and 60 to 70% by weight of the liquid cleaning component. If the component (non-volatile matter) for maintaining the form of the foam sheet in the above is less than 20% by weight, the shampoo component is relatively high and cannot be manufactured into a sheet, and when it exceeds 40% by weight, solubility is deteriorated and usability is poor, making it difficult to commercialize.

In the second step, microbubbles are formed using a homogenizer to form a uniform foam. At this time, as a more uniform foam is formed, the penetration of water is fast and uniform, so that the foam sheet type shampoo is easily dissolved.

In the manufacturing method of the foam sheet-type cleaning product of the present invention, the third step is completed by forming microbubbles through a homogenizer in the above step, molding it in a mold to a thickness of 1 to 5 mm, freezing, and vacuum drying. .

The freeze-drying method is a method of rapidly freezing an aqueous material and then sublimating water in a vacuum to dry it, and is particularly suitable as a method for preparing a bioactive material weak to heat. Accordingly, the manufacturing method of the present invention can maintain the performance of the bioactive material weak to heat without requiring heat in the manufacturing process by using the freeze-drying method.

Furthermore, the present invention provides a portable form of a foam sheet having an open cell structure from the above manufacturing method. We provide cleaning products.

Specifically, the cleaning product having the form of a foam sheet of the present invention is made by homogenizing the viscous composition for maintaining the form of the foam sheet and the liquid cleaning component to form microbubbles and then freeze-drying, and constitutes the viscous composition for maintaining the form of the foam sheet. Due to the water-soluble polymer and nonionic low-molecular-weight substances, the substances discharged after washing are easily decomposed and dissolved, so that the impact on the environment can be minimized.

In particular, the cleaning product in the form of a foam sheet of the present invention maximizes the surface area, so that it is easily hydrated when in contact with water, thereby activating a cleaning function comparable to that of a conventional liquid shampoo or liquid soap.

In addition, it is easy to carry in the form of a foam sheet with a thickness of 1 to 5 mm, and when necessary, it is easily dissolved in water, so it is convenient to use. The functional ingredients contained in it do not deteriorate.

An embodiment of the present invention provides a foam sheet type portable shampoo and soap.

Hereinafter, the present invention will be described in more detail through examples.

These examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

<Examples 1-3> Manufacture of open cell structure foam sheet type shampoo

Step 1: Preparation of a viscous composition for maintaining the form of a foam sheet

100 parts by weight of purified water is added to 100 parts by weight of the raw material mixed with 36% by weight of soluble starch and 64% by weight of sucrose in a water bath container, dissolved under sufficient stirring at 50-60° C., and then cooled to room temperature to remove moisture. A viscous composition for maintaining the form of a foam sheet containing 50% by weight of non-volatile phosphorus was prepared.

Step 2: Preparation of a solution for preparing a foam sheet type shampoo

38% by weight of the viscous composition prepared in step 1 was put into a stainless steel container, and 62% by weight of the liquid shampoo component (GM Gunmo S7 shampoo product, non-volatile matter, 50% by weight) listed in Table 1 below It was added and stirred with a homogenizer for about 10 minutes to prepare a milky white viscous solution containing microbubbles. At this time, the microbubbles were maintained without defoaming even if left for a while.

Step 3: Molding and Lyophilization Steps

The solution prepared in step 2 was molded to a thickness of 1, 2, and 3 mm in a rectangular molding mold having a size of 50 mm × 40 mm, and then placed in a freeze dryer and dried sufficiently. At this time, each thickness was molded to the same thickness as the molding with little shrinkage, has a degree of bendability that can be slightly bent, and a foam sheet type shampoo having an open cell structure was prepared. At this time, only a small portion of the closed (closed) cell (cell) was seen, but it was negligible. The weight was almost identical as the water escaped.

<Example 4> Preparation of foam sheet-type shampoo with open cell structure

A foam sheet-type shampoo having an open cell structure was prepared in the same manner as in Example 1, except that sodium alginate was used instead of water-soluble starch in step 1 of Example 1.

<Example 5> Preparation of foam sheet-type soap having an open cell structure

A foam sheet-type soap having an open cell structure was prepared in the same manner as in Example 1, except that a liquid face soap component was used instead of the liquid shampoo component in Step 1 of Example 1.

<Comparative Example 1>

The same procedure as in Example 1 was performed, except that 51 wt% of soluble starch and 49 wt% of sucrose were mixed in the manufacturing step of the viscous composition for maintaining the form of the foam sheet in Step 1 of Example 1.

<Comparative Example 2>

In step 2 of Example 1, 45 wt% of a component (non-volatile matter) for maintaining the form of a foam sheet and 55 wt% of a liquid cleaning component were added and homogenized and molded, and the same as in Example 1 was performed. .

<Experimental Example 1> Shampoo performance evaluation

The solubility and washing feeling of the foam sheet-type shampoos prepared in Examples 1 to 3 and Comparative Examples 1 to 2 were evaluated, and are shown in Table 2 below.

For solubility, it was judged whether there was a sense of heterogeneity while putting the foam sheet shampoo on the palm and wet with water, and then rubbing the palm to wash it.

The feeling of washing was judged whether or not soluble starch or sucrose remained after washing, and whether there was slippery.

From the results of Table 2, the solubility of the foam sheet-type shampoo prepared in Examples 1 and 2 (thickness 1 mm, 2 mm) was not felt by just rubbing a little on the palm of the hand. On the other hand, the foam sheet-type shampoo prepared in Example 3 (thickness 3 mm) did not feel a little melted when the palm was rubbed, but did not feel foreignness during washing. This is because the thicker the foam sheet shampoo, the greater the amount of water needed, so it completely dissolves in the wet hair and there is no feeling of heterogeneity.

In addition, when washing with a foam sheet type shampoo, all of the foam sheet type shampoos prepared in Examples 1 to 3 were not slippery on the skin and the hair did not remain sticky. Therefore, the foam sheet type shampoo of the present invention is a portable formulation and at the same time, it was confirmed that the cleaning feeling equal to that of the liquid shampoo.

On the other hand, the shampoo prepared in Comparative Example 1 tends to be hard and brittle, and the time until completely dissolved after wetting with water is too long, which has a problem in usability, and the shampoo prepared in Comparative Example 2 also has poor solubility. The advantages of portability and usability are inferior.

In the above, the present invention has been described in detail only with respect to the described embodiments, but it is obvious to those skilled in the art that various changes and modifications are possible within the scope of the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
