Description

  The present invention is a detergent that uses a mixture of polysaccharides including konjac mannan, carrageenan, xanthan gum, etc. as a material for solid retention, and has overcome the drawbacks common to conventional gel-like detergents, that is, the weakness in physical properties. It relates to a cleaning agent featuring a point.

  In the past, rice bran was used as a cleaning agent for the purpose of cleaning the body and improving and maintaining hygiene, and solid soap and liquid cleaning agents obtained by coagulating oils with alkali afterwards, that is, saponification, were used. Widely used. On the other hand, the intermediate physical properties, that is, the detergent in the gel state, although the market scale is still small, has secured a fixed consumption layer in a part, and has come to occupy one field of the detergent market.

Gel-like cleaning agents are designed not only for cleaning the body but also for the purpose of enjoying a unique touch. However, the market for gel detergents is still a fraction of the total detergent. The main reason for this is that the gel has low strength, that is, physical properties, cannot withstand repeated use, and therefore may be disposable once. In other words, the physical properties of the gel detergent are the disadvantages, that is, the points to be improved.
The following explains and defines terms related to physical properties used here.

First, the term “gel” will be explained. Usually, a fluid and viscous substance is called “sol”, and a substance obtained by solidifying it in some way is called “gel”. A gel generally refers to a gel that retains its shape without flowing when placed. The distinction between gels and gels is not always clear, but in the field of detergents and the like, it means a detergent having physical properties similar to jelly as a food, and can be interpreted as almost the same. Here we use the term “gel”, which is widely recognized and used in this market.

In addition, the term “semi-solid”, as will be described in detail below, has a property index that is significantly larger than the gel of the control gel, as compared to the properties of the physical properties of both. It shall be used to distinguish the differences. In addition, the index which becomes the basis of distinction is "breaking strength" and "tensile strength" which are demonstrated below. A cleaning agent having a strength sufficient for the physical property index to be referred to as “semi-solid” is referred to as “semi-solid cleaning agent”, and a detergent that does not reach it is referred to as “gel-like cleaning agent”.

Terms related to the strength of physical properties will be explained. One of the terms “breaking strength” is a fixed shape (in this case, a gel-like detergent molded into a fixed shape (here, a cylinder having a diameter of 30 mm and a height of 25 mm) and a semi-solid detergent manufactured as a prototype. The maximum value of resistance shown until the target is destroyed by using a plunger having a disk shape of 20 mm in diameter in the vertical direction is expressed in grams.

The term “tensile strength” in terms of physical properties means that two L-shaped plungers are inserted into the opening of a sample that has been punched into a fixed shape (here, a ring shape), and the sample is pulled up and down. It shows the maximum resistance value shown in grams until it expires. For die cutting, a special ring-shaped die cutter was pushed into various samples molded into a flat plate shape having a thickness of 5 mm, and the die was cut out.

In the first place, it is natural that gel-like cleaning agents have different characteristics from solid soaps, but as they are cleaning agents, they are sandwiched between both palms or are grabbed and rubbed against the body. And must be able to withstand such use. In other words, the gel-like cleaning agent is basically required to have both “breaking strength” and “tensile strength” defined in the columns 0006 and 0007 at a high level.

The content components of the commercially available gel-like cleaning agent are polysaccharides as the main component of various chemical substances such as sodium laureth sulfate effective for cleaning, perfumes, alcohol for maintaining quality, etc. Xanthan gum or carrageenan is used alone. The semi-solid cleaning agent developed here is not different from a commercially available one in the portion other than holding the solid portion.

  Gel detergent is an intermediate physical property between solid soap and liquid detergent, but has gained some fixed enthusiasts in the field, with its novelty due to its high fragrance and unique touch. As described above, it has occupied a position that can be recognized as one genre.

  However, their physical properties are very fragile, and make users dissatisfied with being fragile and fragile. Further, such a product as shown in the column 0008 does not satisfy the basic properties that should be originally provided.

  The reason for this is that there was difficulty in selecting and combining the materials related to the retention of these solid parts. Overcoming these drawbacks will enable further development in this field and the expansion of the market can also be expected. .

  In this respect, that is, the fact that the physical properties of the gel are strongly improved has been strongly demanded from the user side, and has been loaded on the manufacturer side as the greatest problem. In other words, this solution is key to the market expansion of this type of cleaning agent.

  As means for solving the above-mentioned problems, the present invention aims to increase the strength of the solid part, that is, to increase durability during use, specifically to increase “breaking strength” and “tensile strength”. did. Therefore, we have developed a method of combining two or more kinds of polysaccharides such as xanthan gum, carrageenan, powdered agar, and konjac mannan that have been generally used in the production of confectionery such as jelly.

  Two or more types of polysaccharides are used, one of which needs to be konjac mannan and one of the other needs to be carrageenan or xanthan gum. In addition, “breaking strength” and “tensile strength” can be freely adjusted according to the amount and ratio of konjac mannan and carrageenan or xanthan gum, and if necessary, another polysaccharide can be added. It can also be adjusted.

By heating and dissolving these mixtures and cooling, it is possible to obtain an organized product with the desired physical properties, and as a tactile sensation, those having strong and firm elasticity, soft and stretchable ones can be freely prepared. Their physical property values vary widely, but basically they have the characteristics of “hard to break” and “hard to tear”, and this is a decisive difference from existing gels. For this reason, the method according to the present invention is referred to as a “semi-solid detergent” and is distinguished from a commercially available gel detergent.

  The parts composed of these polysaccharides are related to the solid retention of the semi-solid detergent, and this is combined with various chemical substances such as sodium laureth sulfate, which have an effect on washing, and fragrances as final products. The semi-solid cleaning agent is formed. It is also possible to obtain a semi-solid detergent by this method using a commercially available liquid detergent as a raw material. In any method, a component having an effect of cleaning dissolves from the surface during use and acts on cleaning of the skin and the like. On the other hand, since the solid part has strong physical properties, it can withstand repeated use.

  According to the method invented here, it is possible to prepare a semi-solid cleaning agent having a solid and liquid intermediate physical property and having a strength that can withstand repeated use, which is different from existing gel cleaning agents. Therefore, as a solution to overcome the drawbacks of the existing products, it is possible to absorb the layer that is not satisfied with the existing gel-like cleaning agent as a new product rather than an alternative to the existing product, and take over the market.

  Products such as gel-like detergents are mainly aimed at generations that constantly pursue new things, that is, young people, and the potential market is large. Until now, the main products were those with strong fragrances such as synthetic fragrances, but konjac mannan, or konjac, was emphasized, and fragrances were also natural, regional, and topical materials. It is also possible to provide the product itself as a characteristic of the region. As a result, it is possible to contribute to the revitalization of local industries with a view to tourism.

  A basic embodiment of the present invention will be described. The present invention is basically obtained by forming a solid part with a structure basically composed of a combination of a plurality of polysaccharides, and uniformly mixing and dispersing a detergent component such as sodium laureth sulfate as a synthetic surfactant. It consists of a solid detergent and a method for producing it.

  Hereinafter, the present invention will be specifically described with reference to examples. However, the present invention is not limited to these.

  In order to clarify the effect of the present invention, the properties of two types of commercially available gel detergents (A and B) were used as controls, and a semi-solid detergent prototype prepared by the method developed here was used. The physical properties are summarized in one table. The “breaking strength” of the two control products was 53 g and 32 g, respectively, which were about 1/20 and 1/35 of the prototype. In addition, regarding the “tensile strength”, the commercially available gel-like cleaning agent could not keep its shape and could not be measured, whereas the prototype exhibited a strength of 47 g. Thereby, the improvement effect in the physical property surface by this invention became clear, and it was shown that it is effective also in the physical property improvement of the existing gel-like cleaning agent.

  In order to clarify the relationship between the amount of konjac mannan and other polysaccharides used and their physical properties, gel samples comprising equal amounts of konjac mannan and carrageenan were prepared and the physical properties were measured. Here, four types of samples were prepared using 0.2, 0.3, 0.4, and 0.5 g of each polysaccharide per 100 ml of water. As shown in Table 2, the larger the amount of each used, the larger the “breaking strength” and “tensile strength”, and the harder and harder the tactile sensation becomes, and the greater the resistance to compression and twisting. It was shown that.

  Semi-solid form from three commercially available liquid detergents (referred to as C, D, and E) in the same manner as shown in Example 1 using konjac mannan and other polysaccharides (in this case, carrageenan was used) An attempt was made to prepare a cleaning agent. As a result, as shown in Table 3, although both showed a certain degree of breaking strength and became semi-solid, the tensile strength could not be measured for Samples D and E. This is because the solid part consisting of konjac mannan carrageenan and the detergent component are not sufficiently homogenized, and only the solid part tends to separate from the detergent component and settle, and partially forms a strong gel. Met. Further, the breaking strength of the sample F was a value that was not significantly different from that of the control products (samples A and B) shown in Table 1.

Therefore, another type of polysaccharide (in this case, powder agar) was further added to the sample of Example 3, and the physical properties were measured by the same method. As shown in Table 4, in Samples D and E, “ Both “breaking strength” and “tensile strength” increased, and “tensile strength” also increased in Sample C. This is because the added powdered agar prevented the mixed portion of the polysaccharide composed of konjac mannan and carrageenan from separating from the detergent component and settling. From this example and Example 3, it was shown that according to the method invented here, a semi-solid detergent having the desired physical properties can be obtained from a commercially available liquid detergent.

  The industrial value of the present invention is to provide a new product different from the conventional gel-like cleaning agent in the field of bath preparations and medicinal cosmetics. In addition, various physical properties can be prepared, and a characteristic product can be manufactured by selecting a cleaning agent. In addition, the physical properties of commercially available liquid detergents and gel detergents can be enhanced by a simple technique. Therefore, the application range is wide and the possibility of being used is high.

  In addition, one of the polysaccharides used for holding the solid part needs to be konjac mannan, but konjac mannan is distributed as konjac flour, which is a food material, and is easily available. There is also the significance of revitalizing the industry in this field by opening a new application for konjac flour, which has been used only for food purposes.
