Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pack cosmetic which is mixed with water and applied to the skin for use.
The present invention relates to a pack cosmetic that gives a warm feeling and a comfortable physical stimulus to the skin due to an effervescent effect, in which a carbonate and an organic acid react with water to generate carbon dioxide, and a heat generating substance reacts with water to generate heat.

[0002]

2. Description of the Related Art Heretofore, it has been practiced to increase the temperature of the skin surface to promote blood circulation and to bring out a further cosmetic effect by incorporating a heat-generating substance such as calcined gypsum into cosmetics.

For example, in Japanese Unexamined Patent Publication (Kokai) No. 57-114506, pack cosmetics are mixed with calcined gypsum to promote the metabolism of the skin. In addition, JP-A-57-99514 discloses that cosmetics such as hair shampoo, hair rinse, hair treatment, and hand cleaner are blended with an inorganic substance that generates heat by reacting with water, so that a comfortable warmth can be provided during use. Methods of promoting blood circulation are described.

Here, the heat generated on the skin is such that the temperature change is gentle and the constant temperature is maintained for a long time.
It is preferable in terms of comfortable warmth and blood circulation promoting effect. However, in these conventional cosmetics, a pyrogen is simply blended, or a curing rate modifier such as sodium chloride, tartrate, gelatin, agar, gum arabic or a gelling polymer such as hydroxypropyl cellulose or methyl cellulose is used. It was only used in combination. For this reason, it is difficult to control the exothermic temperature, and in order to increase the sustainability of the exothermic temperature, a large amount of exothermic substance must be blended, which is a safety problem. Further, in the case of a material having high reactivity with water, there is a problem that the heat generation state varies depending on the method of use. Further, JP-A-5-9109 discloses a pack cosmetic in which an exothermic substance is coated with an oil agent, a surfactant, a water-swellable film forming agent and a hydrophobic film forming agent.

[0005]

However, all of these conventional pack cosmetics are intended only to give a warming effect on the skin. INDUSTRIAL APPLICABILITY The present invention is not limited to merely giving a warm feeling to the skin, but also generates carbon dioxide gas during use and gives a comfortable physical stimulus on the skin when the carbon dioxide gas breaks. The object of the present invention is to provide a pack cosmetic that is transmitted to the skin and has an excellent blood circulation promoting effect.

[0006]

As a result of intensive studies, the present inventors have found that a pack cosmetic containing a carbonate, an organic acid, an exothermic substance and a foam stabilizer satisfies the above-mentioned requirements. It came to completion. That is, the present invention is a pack cosmetic comprising 5 to 60% by weight of a carbonate, 5 to 60% by weight of an organic acid, a heat generating substance and a foam stabilizer.

Examples of the carbonate used in the present invention include sodium carbonate, sodium hydrogencarbonate, sodium sesquicarbonate, potassium carbonate, potassium hydrogencarbonate, and sodium sesquicarbonate. These can be used alone or in combination of two or more, and the compounding amount is 5 to 60.
%, Preferably 10-40% by weight. If it is less than 5% by weight, the foaming effect of carbon dioxide gas is insufficient, and if it exceeds 60% by weight, the balance between the foaming effect and the exothermic effect is poor and a sufficient effect cannot be obtained.

Examples of the organic acid used in the present invention include malonic acid, maleic acid, citric acid, malic acid, tartaric acid and succinic acid. These can be used alone or in combination of two or more, and the compounding amount is 5 to 60% by weight.
And preferably 10 to 40% by weight. If it is less than 5% by weight, the foaming effect of carbon dioxide is insufficient, and if it exceeds 60% by weight, the balance between the foaming effect and the exothermic effect becomes poor, and a sufficient effect cannot be obtained, which is not preferable.

Further, the amount of heat generated by these exothermic substances is peculiar to each type, and generally, the less the amount of crystal water of the same inorganic substance, the greater the amount of heat generated. These can be used alone or in combination of two or more, and are prepared according to the purpose so that the temperature becomes 10 to 80 ° C by the reaction with water, and when they are used as cosmetics, they are applied on the skin. It is preferable to control the temperature to be 20 to 50 ° C. The content of these pyrogens is 10-85% by weight,
It is preferably 20 to 70% by weight. If it is less than 10% by weight, the foaming effect of carbon dioxide is insufficient, and if it exceeds 85% by weight, the balance between the foaming effect and the exothermic effect becomes poor.
It is not preferable because a sufficient effect cannot be obtained.

If it is less than 0.1% by weight, the foaming effect of carbon dioxide is insufficient, and if it exceeds 50% by weight, the balance between the foaming effect and the exothermic effect is poor, and a sufficient effect cannot be obtained.
