Description

  The present invention relates to a bath containing a plant or an extract thereof.

  Bathing is an indispensable act in daily life, with various effects such as cleansing the body, warming the body to the core, and relaxing mentally. For the purpose of obtaining various effects at the time of bathing, bathing agents are conventionally used. For example, a moisturizing agent is blended to suppress the skin roughness after bathing in winter and various hot spring ingredients. Is known to improve fatigue and improve warmth.

  Obesity, which has been increasing with changes in dietary habits in recent years, has become a major problem from the viewpoint of beauty, and even bath preparations that have a slimming effect and a tightening effect are required. Furthermore, there is a need for a bath preparation that improves dry skin and the like and has a skin care effect.

Lily licorice is considered to have a lipolysis-promoting action on adipocytes because it was shown that the administration of the extract promotes the release of glycerol from free adipocytes. It has been proposed to use it as an accelerator or slimming agent (Patent Document 1). However, there is no example of using this as a bath agent, and the relationship with the skin-tightening effect and skin care effect is not known.

Manufacture example 1 Manufacture of yellow flower vegetable extract 400 mL of 50% (v / v) ethanol-water mixed solution is added to 40 g of yellow flower vegetables (Shinwa Bussan Co., Ltd.), and after extracting at room temperature (20-30 degreeC) for 7 days, it filters. As a result, 340 mL of extract (18.4 g in terms of dry matter) was obtained.
In addition, the commercially available caffeine (Wako Pure Chemical Industries Ltd.) was used.

Examples 1 to 6 and Comparative Examples 1 and 2
Each component was stirred and mixed in the blending amounts shown in Table 1 and then tableted to prepare each bathing agent as a tablet having a diameter of 40 mm and 40 g. About the obtained bath agent, the “skin tightening effect”, “slimming effect” and “skin care effect” were evaluated by the following evaluation methods. In addition, the yellow flower vegetables extract of Table 1 was described in terms of dry matter using the extract obtained in the above production example.

(1) Skin tightening effect Five expert panelists evaluated the skin tightening effect after bathing twice a week for 4 weeks in a bath dissolved in 150-200 liters of bath water. It was. The evaluation was performed by comprehensively judging the skin-tightening effect of the skin around the stomach, upper arms, buttocks, calves, etc. and scoring as follows. The temperature of the bath water was in the range of 35 to 42 ° C., which was the panel temperature preferred.
3 points: I feel a strong effect.
2 points: Feels a squeezing effect.
1 point: Feels a slight effect.
0 point: I do not feel the squeezing effect.

(2) Slimming effect Five professional panelists evaluated the slimming effect after bathing each bathing agent in 150-200 liters of bath water twice a week for 4 weeks. The evaluation was performed by comprehensively judging the slimming effect of the whole body around the stomach, upper arms, buttocks, calves, etc., and scoring as follows. The temperature of the bath water was in the range of 35 to 42 ° C., which was the panel temperature preferred.
3 points: A strong slimming effect is felt.
2 points: Feel the slimming effect.
1 point: Feel the slimming effect slightly.
0 points: No slimming effect is felt.

(3) Skin care effect Each bath was dissolved in 150 to 200 liters of bath water and bathed twice a week for 4 weeks. After 1 hour in the environment at 25 ° C. after bathing, the skin conductance value of the inner side of the thigh was measured and compared with the skin conductance value before the start of the test, and scored as follows. The temperature of the bath water was in the range of 35 to 42 ° C., which was the panel temperature preferred.
3 points: Skin conductance value is extremely increased (Δ skin conductance ≧ 8 μS).
2 points: Skin conductance value increased (8 μS> Δ skin conductance ≧ 4 μS).
1 point: The skin conductance value slightly increased (4 μS> Δ skin conductance ≧ 2 μS).
0 point: Skin conductance value does not change (2 μS> Δ skin conductance).

  Table 1 shows the average score of five people for each item as the evaluation result.

As shown in Table 1, the bathing agent containing yellow rapeseed or its extract is superior to the bathing agent not containing yellow rapeseed or its extract in terms of skin tightening effect, slimming effect, and skin care effect. showed that.
Furthermore, it was confirmed that these effects were further enhanced by using caffeine and a carbon dioxide gas generator in combination.
