DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath preparation, and more particularly, to a powdery preparation which, when dissolved in hot water in a bath tub, develops a desirable scent or color, or imparts a medicinal effect to the skin or a beautiful skin effect. It relates to a bath agent.

[0002]

2. Description of the Related Art As bath agents, there are powders of materials having desired functions such as fragrances, coloring agents and skin beautifiers. Such a bath agent is melted by being poured into hot water in a bathtub, and exhibits various functions such as color and aroma. In a conventional bath agent, when it is poured into hot water, it is melted as quickly as possible so that the desired functions are exhibited. Therefore, when the bath agent is added to the hot water in the bathtub, a predetermined color or scent immediately develops, but after that, with the added water or hot water, the color or scent may be thinned, but it is almost the same. Maintain a good color or fragrance.

On the other hand, after pouring a bath agent into hot water,
A bath agent that changes color with the passage of time has been proposed, and is disclosed, for example, in JP-A-62-252715. In this prior art, a bath component containing a pigment other than the capsule is encapsulated in a soluble capsule containing a pigment. When this bath agent is poured into hot water, the capsule is first melted and the added pigment colors the hot water. afterwards,
When the capsule is melted after a certain period of time, the bath component and the dye encapsulated therein begin to melt. At this stage, the hot water in the bathtub is mixed with
It will change to a mixed color with the encapsulated dye, which will later dissolve. If different aroma substances are contained in the capsule and the internal bath component, the fragrance changes over time. In addition, a method in which a plurality of types of capsules having different film thicknesses and materials are mixed to dissolve differently for each of the plurality of types of capsules, and thus a method of imparting a change in color or scent is also disclosed.

[0004]

However, the above-mentioned conventional bath preparations which change color and fragrance as described above are troublesome in manufacturing capsules and enclosing bath preparation components in capsules. There was a disadvantage that the cost was high. In particular, it is very difficult to change the thickness of the capsule to change the melting method, and it is necessary to strictly control the blending of the materials and the manufacturing process. In addition, it is costly to prepare a plurality of types of materials having different melting methods as capsule materials, and it is difficult to select a combination of capsule materials that can be used as a bath agent.

[0005] Therefore, an object of the present invention is to provide a bath agent, such as color and fragrance, which changes with time and
An object of the present invention is to provide a bath agent which is easy to manufacture and inexpensive.

[0006]

The bath agent according to the present invention, which solves the above problems, has the following constitution. (1) A mixed material of gelatin and a gelatin decomposition product and a functional component exhibiting a function as a bath agent was powdered .
Consists of powder. (2) Function component containing the ing a combination of different kinds of powder. (3) Powders having different functional components, with different mixing ratios of gelatin and gelatin decomposed product.

As the gelatin, ordinary gelatin which has been generally used in the past can be used as it is. That is, it can be obtained by extracting the bone or skin constituting the connective tissue of an animal by ordinary means. More specifically, gelatin is obtained by subjecting a bone or skin material from which gelatin is to be extracted to a pretreatment, such as an alkali treatment by immersion or an acid treatment such as hydrochloric acid or sulfuric acid, followed by hot water extraction. Can be The raw material of gelatin and the processing method are not limited to the above-mentioned methods, and the conditions employed in normal gelatin production can be freely applied.

When a functional component described later contains a dye, it is preferable to use an acid-treated gelatin as the gelatin. This is because, when alkali-treated gelatin is used, the charge of the pigment and the gelatin repel, and the pigment is likely to escape from the powder before the gelatin is dissolved, and it is difficult to control the dissolution of the pigment. On the other hand, acid-treated gelatin has a high ability to retain the dye, and it is easy to control the dissolution of the dye due to the difference in the solubility of gelatin.

The gelatin decomposition product is produced using the same raw materials as the above-mentioned ordinary gelatin or the above-mentioned gelatin itself. The following method can be applied to the manufacturing method. Thermal decomposition method: Thermal decomposition at a temperature of 100 ° C. or more. Acid decomposition method: The pH is lowered by using a mineral acid such as hydrochloric acid or sulfuric acid, and then decomposition is performed at 70 ° C. or higher for several hours.

[0010] Alkaline decomposition method: decomposition treatment is performed at pH 10 or higher and 80 ° C. for several hours using an alkali agent such as potassium hydroxide, sodium hydroxide, sodium carbonate, or ammonia. Enzymatic degradation method: 40-70 using a protease.
Decompose at ℃ for several hours.

Further, a pressure decomposition method in which decomposition is performed by applying a high pressure can also be applied. A gelatin decomposition product is obtained by using any one of the above processing methods or a plurality of the methods in combination. The gelatin decomposition product has a smaller molecular weight than the above-mentioned ordinary gelatin, and has a weight average molecular weight (Mw) in the range of 1,000 to 30,000, preferably in the range of 5,000 to 20,000. Used. If the molecular weight of the gelatin decomposition product is too large, the effect of adjusting the dissolution rate described later cannot be sufficiently achieved. If the molecular weight of the gelatin decomposition product is too small, the shape retention performance and the like become poor. The molecular weight of the gelatin decomposition product can be adjusted according to the processing conditions of the decomposition treatment. The gelatin decomposition product is used after being subjected to filtration and purification treatment after the decomposition treatment. The obtained gelatin decomposition product has a viscosity of 15 mp or less (JIS-K6503) and dissolves in water at room temperature without swelling. Even if left as it is, it does not solidify in a jelly state.

The functional component is to add color or scent to hot water,
Giving medicinal and beautiful skin effects to the skin,
It is a substance that can exert some function when used as a bath agent. Specifically, materials added to pigments, fragrances, fats and oils, crude drugs, and other ordinary medicinal agents are used. Powders are produced by, for example, drying and pulverizing a solution in which gelatin, a gelatin decomposition product and a functional component are mixed as described above. The specific method of producing powder is
This is the same as in the case of ordinary bath agents or other powder products. For example, an aqueous solution of gelatin and a gelatin decomposed product produced by the above method is uniformly mixed in a high concentration state, and a raw material aqueous solution in which a functional component is dissolved is prepared. The powder for a bath agent of the present invention is obtained by pulverizing using a pulverizing device of the present invention. At this time, it is preferable that the raw material aqueous solution be dried until the water content becomes 16.0% or less, and then pulverized. The drying is more preferably performed until the water content becomes about 6.5 to 16%. If the water content before the pulverization treatment such as pulverization is too large, the dissolution rate of the obtained powder cannot be properly adjusted. The same conditions as in the case of ordinary gelatin production can be applied to the drying method and apparatus, the pulverizer, and the pulverization conditions. The pulverization is preferably performed until the particle size of the powder becomes 3.0 mm or less, preferably in the range of 0.2 to 1.0 mm. If the powder particle size is too large, the solubility is inferior, and if the powder particle size is too small, the production is troublesome, and problems such as dust pollution associated with handling and storage also occur.

When producing the powder as described above, a plurality of types of powder containing different functional components are produced. Then, powders having different functional components have different mixing ratios of gelatin and a gelatin decomposition product. The different functional components are, for example, pigments having different colors, fragrances having different scents, and the like. The difference between the mixing ratio of gelatin and gelatin degraded product is that when powders containing functional components that are to be dissolved quickly when a bath agent is added to hot water, the compounding ratio of gelatin degraded product is increased and the functional components that are to be dissolved slowly are added. In the powder to be contained, the blending ratio of the gelatin decomposition product is reduced. The mixing ratio of gelatin to the gelatin decomposition product is such that the ratio of gelatin: gelatin decomposition product is 10: 0 to 3: 7, preferably 10: 0 to 5: 5.
Adjust within the range.

It is easier to produce a powder and to adjust the dissolution rate by using a relatively high concentration aqueous solution of gelatin and a gelatin decomposition product. Specifically, it is preferable to use a 20 to 40% by weight aqueous solution as gelatin, and to use a 20 to 50% by weight aqueous solution as a gelatin decomposition product.

[0015]

Since gelatin has a melting temperature of about 40 to 50 ° C., it is soluble to some extent in hot water for bathing (around 40 ° C.). However, its dissolution rate is not very fast.
On the other hand, the gelatin decomposition product can be dissolved even in normal-temperature water, so that it can be very quickly dissolved in hot water for bathing. Accordingly, if the powder is a powder in which the gelatin and the gelatin decomposition product are uniformly mixed, the powder exhibits an intermediate dissolution rate in accordance with the mixing ratio of the gelatin and the gelatin decomposition product. The dissolution rate of the powder can be arbitrarily adjusted by adjusting the mixing ratio of the gelatin and the gelatin decomposition product.

Therefore, a powder containing a certain functional component can be obtained by producing a powder comprising gelatin, a gelatin decomposed product and a functional component, and changing the mixing ratio of the gelatin and the gelatin decomposed product in a powder having different functional components. The body dissolves faster, and powders containing other functional ingredients dissolve slowly. Specifically, when using a different color pigment as a functional component, for example, if the powder containing the yellow pigment is first dissolved,
If the color of the hot water is colored yellow, and after a while the powder containing the blue pigment is dissolved, the color of the hot water will show a green color in which the yellow and blue are mixed. If powders with different scents are combined as powders with different functional ingredients,
It is easy to see that the scent can be changed over time.

In the present invention, since the same raw material is used as the original raw material, ie, gelatin and a gelatin decomposition product, it is possible to mix them uniformly, and it is possible to change the mixing ratio at an arbitrary ratio. it can. Normally, when different kinds of materials are mixed, if the mixing ratio is changed, it may not be possible to mix uniformly, or it may hinder the retention of functional components or powdering, but gelatin and gelatin decomposition Such a problem does not occur at all if there is a combination of objects. In addition, in the case of different kinds of materials, there is a case where they are deteriorated by the interaction or have a bad influence on the functional components.

In particular, when gelatin and a gelatin-decomposed product are mixed in a high-concentration solution state and then dried and pulverized, small molecules of the gelatin-decomposed product are homogeneous in the large molecular structure of gelatin in the particles. Are distributed. When the powder in such a state comes in contact with hot water, the gelatin decomposition product is melted, and the hot water easily penetrates into the gaps in the molecular structure of gelatin. The solubility of the whole powder can be delicately controlled by the difference in the amount of the compound.

[0019] Further, gelatin and gelatin-decomposed products themselves have a function of smoothing the texture of hot water and giving moisture to the skin.

【Example】

-Example 1-As a bath agent, a color changing with time was manufactured.
The following powders were prepared and mixed to prepare a bath agent. <Blend: parts by weight> Powder Powder Powder Acid-treated gelatin 060 100 Gelatin decomposed product 100 400 Dye A (Yellow No. 4) 5--Dye B (Blue No. 1) -5-Dye C (Yellow 202) -5) Powders having the above composition were separately prepared by a conventional method. Each powder was mixed at a ratio of 1: 1: 1 to obtain a bath agent.

When this bath agent was put into hot water at 40 ° C., the color of the hot water changed as follows. Color tone change: 5 seconds after introduction = yellow.後 After 30 seconds = changed from yellow to green.後 After 3 minutes = Changed from green to yellow-green.

When each powder is separately poured into hot water at the same temperature as above, the powder melts in about 5 seconds and changes the color of the hot water to yellow, and the powder melts in about 30 seconds. It was also confirmed that the color of the hot water changed to blue, and the powder melted after about 3 minutes, changing the color of the hot water to yellow. -Example 2-A bath agent having a different color change from that of Example 1 was produced.

[0023] When the powder and the bath agent in which the powder were mixed were put into the same hot water, the color of the hot water initially turned yellow, but then changed from yellow to orange.

[0024]

The bath agent according to the present invention as described above contains different functional components, and is used in combination with powders having different blending ratios of gelatin and gelatin decomposed product, whereby the bath agent is added to hot water. After that, it is possible to provide a bath agent whose color, fragrance and the like change over time.

In particular, the solubility of each powder can be freely controlled only by adjusting the mixing ratio of gelatin and the gelatin decomposition product, so that the thickness of the capsule containing the bath agent component can be changed or the material of the capsule can be changed. It is possible to provide a bath agent which can enjoy the above-mentioned change easily and at low cost without the troublesome work of changing it. Gelatin and its degraded gelatin have excellent safety for the human body and can be expected to have a useful effect on the skin. Therefore, they can exert not only a carrier for functional components but also an effect of improving the function of a bath preparation.
