Description

  The present invention relates to a carbon dioxide generator-containing bath preparation composition.

  A bath agent composition is generally a mixture of an inorganic salt mixture such as mirabilite, borax, sulfur, salt, carbonate, and the like containing a fragrance, a colorant, a plant extract, an organic acid, etc. By applying moderate stimulation to the surface, blood circulation is activated, and fatigue recovery and metabolism are promoted. In these bath preparation compositions, there is a foaming bathing agent that combines carbonate and organic acid. Carbon dioxide bubbles are generated in the bathing water to enhance blood circulation promotion, relaxation and refreshment, and bathing Has the effect of making fun. The fragrance works to further enhance such a bathing effect.

So far, bathing agents that maintain the strength of the scent are known (Patent Document 1), but there are few studies on the quality of the scent.
On the other hand, a bathing agent in which an amino acid (arginine, serine), a natural pigment (riboflavone), and a fragrance are blended in an effervescent bathing agent (Patent Document 2), or a bathing agent in which an amino acid (glycine, arginine) is blended in an effervescent bathing agent. Although (patent document 3) is known, all raise the moisturizing effect and it does not mention the technique regarding fragrance, especially the quality of fragrance.

Test 1 Confirmation of solubility [confirmation method]
0.15 g or 2 g of glycine in bath water in which 35 g of 40 ° C., 150 liters of hot water, or 35 g of a powder of sodium bicarbonate and fumaric acid mixed in 1 / 0.1, 1 / 0.5, 1/1 The dissolution time of glycine when added and allowed to stand was measured.

[result]
The results are shown in Table 1. The dissolution time of glycine was shortened by setting the content ratio of carbonate and organic acid to 1: 0.5 or more. Therefore, by setting the content ratio of carbonate and organic acid to 1: 0.5 or more, the dissolution rate of glycine in the bath water is increased, and the component contained in the bath water (tap water) is promptly increased. It was clarified that the bathing agent has a good solubility with no undissolved effect while acting.

Example 1 Evaluation of Sustainable Quality of Fragrance The composition shown in Table 2 was mixed by a conventional method and compression molded to produce a 45 g / tablet tablet bath.

[Evaluation method]
Dissolve 1 tablet of bathing agent in 40 ° C / 250L bath water, special panelists (2 persons) for the original fragrance after 1 hour (citrus-floral fragrance) and the change in fragrance caused by changes over time. ) Was subjected to sensory evaluation according to the following evaluation criteria.
The bath water used in this experiment has a total evaporation residue of 170 mg / L, calcium hardness of 51 mg / L, magnesium hardness of 18 mg / L, sulfate ion of 37 mg / L, bicarbonate ion of 27 mg / L, sodium of 25 mg / L, It contained 11 mg / L of nitrate ion, 21 mg / L of silica, and 2 mg / L of free chlorine. The electric conductivity was 27 mS / m and the pH was 7.2.

<Evaluation criteria>
++: Feel strongly +: Feel ±: Feel slightly-: Not feel

[result]
The results are shown in Table 3. As is apparent from Table 3, one hour after the bathing agent was dissolved, the bathing agent of the present invention did not feel the change in the fragrance due to the change over time, and the fragrance original fragrance was sufficiently felt. It was found that the original fragrance quality was maintained.
From this fact, the bath agent composition of the present invention has an original fragrance even under severe bathing conditions in which the amount of bath water is large and the concentration of the fragrance is low, and the quality of the fragrance is easily affected by the water quality. It became clear that the quality of the aroma lasts for a long time.
