Field of the Invention The present invention relates to a bath additive characterized by containing trehalose which is a non-reducing sugar. The bath agent of the present invention belongs to a health care product that can be expected to have a moisturizing effect and a skin roughening prevention effect more than conventional bath agents by adding trehalose. 2. Description of the Related Art In recent years, many types of bath salts have been sold and used due to an increase in awareness of health and beauty.
Not only mental relaxation by bathing, but also moist and smooth feeling of the skin are expected. One of the patents relating to bath salts is Japanese Patent Publication No. 53-1259. The purpose of the patent is to add an amino acid or a salt thereof in order to prevent the dye in the bath salts from discoloring due to chlorine in the tap water. That is. [0003] Further, in order to moisturize the skin after bathing and to give a smooth feeling, an acrylic resin having a submicron particle size is added to the bath, and a patent relating to a bath containing carbon dioxide gas generator (Japanese Patent Publication No. 3-62690, Tokuhei 3
-62691, Tokuhei 3-62692)
In both cases, the moist and smooth feeling is promoted by the combination of the oil component and the fine particles. However, when an oil component is blended, a sticky feeling may be felt depending on the condition of the skin. DISCLOSURE OF THE INVENTION [0004] The present invention relates to the use of trehalose, which is a non-reducing sugar, as an active ingredient in order to obtain a bathing agent capable of enjoying a moist and smooth skin feeling. To consider. [0005] The use of trehalose, which is expected to provide a moist and smooth skin effect as a bathing agent, has also been clarified, and the present invention has been completed. [0006] That is, the present invention, the door Reharosu 15
The present invention relates to a bath agent characterized in that it contains from 100% by weight to 100% by weight . Trehalose used in the present invention has three isomers (α, α-form, α, β-form, β, β-form).
Α) and α-form are usually used, but the present invention is not limited thereto. The trehalose powder usually has 2 moles of water of crystallization per 1 mole of trehalose, but the trehalose used in the present invention may be the hydrate or anhydrous. If the concentration of trehalose in the bath tub of the present invention in the bathtub is 3 ppm to 200 ppm, a moist feeling and a smooth feeling can be confirmed on the skin during and after bathing. Preferably, a trehalose concentration of between 5 ppm and 100 ppm, more preferably between 15 ppm and 100 ppm is desired. Therefore, it is necessary to add a trehalose-containing bath agent to the bath so as to have the above concentration. Here, if it is less than 15 ppm, the effect of trehalose on the skin's moist and smooth feeling cannot be remarkably obtained. Also,
When the content is more than 200 ppm, a sticky feeling on the skin appears, so that it is difficult to use as a bath additive. [0009] Usually, the bathtub volume is 200L to 300L,
Since the weight of the bath additive used per time is from 20 g to 30 g, in the present invention, the weight of the bath agent as a product is 25 g for each batch, and the volume of the bath tub is 250 L as described below. Therefore, the trehalose content in the bath product used in the present invention must be 15 % by weight to 100% by weight. The trehalose concentrations described in the present invention are all trehalose-equivalent concentrations. The bath may be in the form of a solution,
It may be a powder. Trehalose, which is a main component of the bath agent having the above-mentioned effects, has high solubility in water, so there is no particular problem with powder, but in order to further increase the solubility,
Preferably, fine powder of 10-100 μm is obtained by pulverization. The bath preparations described in the present invention may contain, as necessary, commonly used inorganic salts, organic acids, pigments, vitamins, fragrances, surfactants, tannins, amino acids, crude drugs and the like. In this way, the use of the above-mentioned bath agent which makes trehalose present in a bathtub at a specific concentration or more can provide a moist feeling and a smooth feeling to the skin.
Hereinafter, the present invention will be specifically described based on examples. EXAMPLES A mixture having the composition shown in Table 1 was pulverized with a pin mill, and 25 g of each mixture was packaged to obtain a bath agent 1 to a bath agent 7. [Table 1] EXAMPLE One package of 25 g of each of bath agent 1 to bath agent 6 was dissolved in 250 L of water, and heated to 41 ° C. Further, two bath additives 6 were added and dissolved in the bathtub and heated to 41 ° C. Sensory evaluation on the moist feeling and smoothness of the skin after bathing was performed in the following manner by 10 men and women. Table 2 shows the average of the obtained scores. Very good --- A fairly good --- B good --- C ordinary --- D not very good --- E [Table 2] From the results in Table 2, it can be seen that trehalose contained 15 % to 100% by weight of trehalose in the product bath agent, and that the bath tub contained 15 ppm to 200 ppm of trehalose, which gave a remarkably moist feeling and a smooth feeling. It turned out to be obtained. The effect of the present invention is as follows. The effect of the present invention is as follows. The trehalose is contained in the bathing agent in the product at a certain level or more, and the concentration of trehalose in the bathing tank is made at a certain level or more, so that the skin becomes moist. I found that I could get a smooth feeling.
