DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a bath preparation composition having an excellent skin moisturizing effect.

[0002]

2. Description of the Prior Art A bath composition generally comprises a mixture of an inorganic salt such as sodium sulfate and sodium hydrogen carbonate mixed with a fragrance, a pigment and a humectant. It restores fatigue and gives a feeling of relaxation by giving blood and color tone, promoting blood circulation and warming effect by the action of inorganic salts.

[0003] However, in the conventional bath compositions, although the heat-retaining effect is recognized in the trunk, none of them can provide a sufficient heat-retaining effect at the distal ends of the limbs.

[0004] Further, as an effect other than heat retention, there is an example in which an oily substance, a water-soluble polymer, a milk component and the like are contained for the purpose of improving the firmness of the skin after bathing, but the effect is not sufficient. Was not.

[0005] The present invention has been made under such circumstances, and its object is to mix lactose and loquat leaves, and to prepare cucumber, peonies, peppermint, shobu,
By containing at least one member selected from the group consisting of Jujuya, it has been found that the effect is effectively derived, the effect of retaining heat on the periphery is improved, and a moist feeling is given by eliminating bulkiness of the skin. Completed the invention.

[0006]

DISCLOSURE OF THE INVENTION The present invention comprises lactose and loquat leaves, and comprises eucalyptus, peonies, peppermint,
A bath agent composition comprising at least one member selected from the group consisting of Shobu and Juyaku.

Hereinafter, the present invention will be described in detail. The amount of lactose used in the present invention is Ru Ah required to be from 0.5 to 90 wt%. If the amount is less than 0.5% by weight, a moist feeling cannot be obtained, and if the amount is more than 90% by weight, the feeling of hot water becomes sticky and unpleasant.

The loquat leaf, which is a crude drug used in the present invention, is a loquat (Eriobotrya japonica Lindl) leaf. Touki is the root of Touki (Angelica acutiloba Kitagawa) or other closely related plants. Peony is a peony
(Paeonia lactiflora Pallas) or a root of a closely related plant. Mentha is Mentha arvensis linne var.pi
perascens (Malinvaud) or related plants. The show was Shobu (Acorus calamas linne var.an
gustatus Besser). Juyaku is Dokudami (H
outtuyia cordata thunberg).

As these crude drugs used in the present invention, dried, shredded and pulverized (crude powder) are used, and of course, these crude drugs are extracted by a known method such as water or alcohol. It is also possible to use a crude drug extract) or a powder obtained by drying the extract (crude extract powder).

[0010] The amount of the crude drugs are both herbal powder is adjusted manufactured state of the herbal, or if any of the powder herbal extract, is necessary for the entire composition are each 0.001 wt% is there. If it is less than 0.001% by weight, no peripheral heat retention effect can be obtained, and if it is more than 40% by weight, no effect can be obtained, which is disadvantageous in cost. In the case of both herbal extract tone made states of herbal medicine, as each of dry residue, it is necessary that each 0.001 wt% based on the total composition.

The effect of the present invention can be further enhanced by further mixing an inorganic salt component. As the inorganic salt component, sodium sulfate, sodium hydrogen carbonate,
Sodium chloride, calcium nitrate, potassium nitrate, sodium nitrate, aluminum sulfate, sodium polyphosphate, ammonium chloride, iron sulfate, sodium phosphate, magnesium sulfate, sodium thiosulfate, sodium sesquicarbonate, sodium sulfide, borax, calcium oxide, magnesium carbonate , Potassium chloride and the like. Furthermore, a fragrance | flavor, a pigment | dye, etc. can also be added to the bath agent composition of this invention.

[0012]

EXAMPLES The present invention will be specifically described below with reference to examples, but evaluation items and methods will be described first.

(1) Method of evaluating peripheral heat retention effect Ten subjects were selected, and hot water was administered with the bath compositions shown in Tables 1 and 2 (about 180 liters of hot water was charged with 30 g of the bath composition).
The skin surface temperature change after bathing was measured. In addition, evaluation by questionnaire was performed. Conditions; bath temperature: 41 ° C Bath time: 10 minutes Room temperature:
26 ° C Measurement site: Hand and back measurement equipment; Thermography (THER manufactured by NEC Sanei)
MOTRACER 6T66) Questionnaire evaluation method; About warmth of limbs 5 points──Very warm 4 points──Somewhat warm 3 points──Normal 2 points──Slightly warm 1 point──Very warm

[0014]

[Table 1]

(2) Evaluation method of skin moisturizing effect Ten subjects were selected, and in winter season when they were easy to dry, Table 1 and Table 2 were used.
The feet were partially bathed three times a day (morning, noon, night) for 5 minutes three times a day in hot water (bath composition about 180 liters of hot water) into which the bath composition was added. The state of the sulcus was observed, and further evaluated by a questionnaire. Conditions; Bath temperature: 41 ° C Partial bathing period: 10 days Observation site: Forefoot side Observation equipment; Enlarged video camera (VIDEOM manufactured by Wilson)
ICROSCOPE SYSTEM) The score of the state of the sulcus observed; 5 points {very clear sulcus 4 points} slightly clear sulcus 3 points {slightly unclear sulcus 2 points} Skin sulci is unclear 1 point ── Skin sulcus is hardly recognized Questionnaire evaluation method 5 points ── Very moist skin 4 points ── Slightly moist 3 points ── Normal 2 points ── Slight skin 1 point つ く Very heavy skin

Production Example: Loquat leaf extract powder used in the examples is obtained by chopping 500 g of loquat leaf crude drug into approximately 10 times the amount of 70%
An aqueous ethanol solution was added and the mixture was boiled and extracted for 2 hours. The extract was filtered, and the filtrate was spray-dried to obtain a dry extract powder.

Examples 1 to 5 and Comparative Examples 1 to 3 Bath compositions having the composition shown in Tables 1 and 2 were prepared by a usual method of mixing powders, and the above-mentioned tests were carried out. Table 3 shows the results. The numbers in Tables 1 and 2 are% by weight.
Is shown.
