Description

The present invention relates to a gel-like cleansing cosmetic. More specifically, it relates to an aqueous gel cleansing cosmetic.

Makeup cosmetics and UV protection cosmetics have the effect of making the skin look beautiful and protecting the skin from external stimuli, and are indispensable in the life of modern society. However, since these cosmetics contain a large amount of oily components and inorganic pigments, they block the pores of the skin, hinder metabolism, and the cosmetics themselves are gradually oxidized, so long-term use causes skin problems. May cause. Therefore, it is necessary to remove these cosmetics once a day with a cleansing agent.

As a cleansing cosmetic, in recent years, the fresh feeling of use, which is a characteristic of gels, has been preferred, and cleansing gels occupy a large share. Aqueous gels containing water as a main component (see Patent Document 1) and oil-based gels are known. Aqueous gels may be formulated with a small amount of oil dispersed in them, but these can be washed away with water and have a refreshing feel without the need for double face washing, but they are inferior in cleaning effect or after washing the face. Some are sticky.

The oil-based gel has a good affinity with make-up cosmetics, and there are oil gels and W / O emulsified type or O / W emulsified type emulsified types. Oil gel and W / O emulsified type have high cleansing power, but they cannot be washed with water because the oil phase is a continuous phase. Is. The O / W emulsified type (see Patent Document 2) can be washed away with water, but it is not always satisfactory for the removal of makeup cosmetics in recent years. Therefore, recent makeup makeup It has been desired to develop a cleansing cosmetic that is suitable for the price.

Japanese Unexamined Patent Publication No. 2012-6862 Japanese Unexamined Patent Publication No. 2000-26238 Japanese Patent No. 5253483 Japanese Unexamined Patent Publication No. 2001-19176 Japanese Unexamined Patent Publication No. 2015-16441

It is said that making beautiful skin starts with washing your face. In cleansing cosmetics for maintaining beautiful skin, it is most important how to reduce the damage to the skin without rubbing when removing the makeup.
An object of the present invention is to provide a gel-like cleansing cosmetic that does not foam, that is, does not need to be rubbed and has little damage to the skin, but has an excellent makeup removing effect and does not require a double face wash. ..

As a result of various studies, the present inventor produces water as the main raw material for aqueous gel-like cleansing in the cathode chamber of a three-chamber type electrolyzer instead of the purified water conventionally widely used in gel-like cleansing. If you use alkaline cleansing water, you can remove cosmetics that have been oxidized by the reducing power without adding oil, and you can remove makeup without foaming and rubbing, so there is less damage to the skin. Moreover, it was found to have excellent moisturizing power after cleansing.
At the same time, when the hydrolyzed eggshell membrane component is contained, the moisturizing effect after washing the face is further enhanced in combination with the moisturizing effect of the electrolytically reduced water, the dryness after washing the face is prevented and the skin is moisturized, and the electrolytic reduction is performed. We have found that the hydrolyzed eggshell membrane component moisturizes and gives elasticity, firmness and luster to the skin where water has penetrated to the pores and cares for darkening, and the skin-beautifying effect is increased, leading to the completion of the present invention.

Further, the pH can be adjusted in the acidic direction by mixing the alkaline reduced water generated in the cathode chamber of the three-chamber type electrolyzer with the acidic oxidized water generated in the anode chamber of the three-chamber type electrolyzer. Moreover, sterilization by oxidized water, sterilization effect and skin regeneration effect are also added.

Based on the total weight of the gel-like cleansing cosmetic, the ratio of the three-chamber electrolyzed water should be 40 to 90% by weight, the ratio of the hydrolyzed eggshell membrane component should be 0.0001 to 2% by weight, and the hydrolyzed eggshell membrane component. Is preferably an enzymatically hydrolyzed eggshell membrane component and / or an alkali-decomposed eggshell membrane component, and further, even a small amount of the surfactant content can improve the bactericidal property of the skin.

The present invention relates to the following gel-like cleansing cosmetics (1) to (9).
(1) A gel-like cleansing cosmetic comprising a three-chamber type electrolyzed water as a main component and a hydrolyzed eggshell membrane component.
(2) The gel-like cleansing cosmetic according to (1) above, which contains 40 to 90% by weight of the three-chamber type electrolyzed water and 0.0001 to 2% by weight of the hydrolyzed eggshell membrane component.
(3) The gel-like cleansing cosmetic according to (1) or (2) above, wherein the three-chamber type electrolyzed water is alkaline three-chamber type electrolytically reduced water.
(4) The gel-like cleansing cosmetic according to (1) or (2) above, wherein the three-chamber type electrolyzed water is a mixed water of alkaline three-chamber type electrolytically reduced water and acidic three-chamber type electrolytically oxidized water. ..
(5) The three-chamber type electrolytically reduced water has an anode chamber provided with an anode electrode, a cathode chamber provided with a cathode electrode, an intermediate chamber provided between the anode chamber and the cathode chamber, and an anode chamber and an intermediate chamber. A three-chamber electrolyzed water generator equipped with a diaphragm arranged between the anode chambers and a diaphragm disposed between the cathode chamber and the intermediate chamber was used to supply water to each of the anode chamber and the cathode chamber. The gel-like cleansing cosmetic according to (3) or (4) above, which is the reduced water generated in the cathode chamber by supplying an aqueous sodium chloride solution to the intermediate chamber and performing electrolysis.

(6) The gel-like cleansing cosmetic according to any one of (1) to (5) above, wherein the hydrolyzed eggshell membrane component is an enzymatically decomposed eggshell membrane component and / or an alkali-decomposed eggshell membrane component.

(8) The gel-like cleansing cosmetic according to any one of (1) to (7) above, which does not contain mineral oil and monohydric alcohol.
(9) The gel-like cleansing cosmetic according to any one of (1) to (8) above, which has a pH of 5 to 7.

Since the gel-like cleansing cosmetic of the present invention uses alkaline reduced water generated in the cathode chamber of the three-chamber type electrolyzer, which is the three-chamber type electrolyzed water, as the main raw material water, it contains oil due to its reducing power. Even if you don't have it, you can float the cosmetics and take them, and the reduced water can penetrate into the pores to care for darkening.
The reason why cleansing cosmetics foam is because they rub, and the gel-like cosmetics of the present invention are non-oil type that does not foam and can remove makeup without rubbing, which has never existed before, and causes damage to the skin. few. Moreover, it has excellent detergency, and all type cosmetics such as oil-based, water-based, and water proof can be removed well, and even dolan cosmetics used by entertainers can be removed firmly.

In addition, since it is an aqueous gel, double face washing is not required, and the moisturizing power of electrolytically reduced water that does not affect sensitive skin makes the skin moist without washing the face after wiping off the gel-like cleansing. Also, if you wash your face, it will be finished cleanly without leaving any rinsing residue. Furthermore, by using the hydrolyzed eggshell membrane component in combination with electrolyzed water, not only the moisturizing power is synergistically enhanced, but also the skin becomes firm and glossy, and the skin becomes elastic and fresh.

Furthermore, by using alkaline electrolytically reduced water mixed with acidic oxidized water generated in the anode chamber of the three-chamber type electrolytic device as the main raw material water, the sterilizing, sterilizing effect and skin regeneration effect of the oxidized water are used. And even if the content of the surfactant is small, the bactericidal property of the skin can be improved. Further, since the pH can be lowered by mixing the acidic oxidized water, the storage stability is improved and the irritation to the skin is reduced.
As described above, the gel-like cleansing cosmetic of the present invention is epoch-making in detergency and beauty effect, and does not contain mineral oil or monohydric alcohol, so that it does not adversely affect sensitive skin.

The gel-like cleansing cosmetic of the present invention is characterized in that alkaline 3-chamber electrolyzed reduced water, which is a 3-chamber electrolyzed water, is used as the main raw material water of the aqueous gel and contains a hydrolyzed eggshell membrane component. ..
The alkaline three-chamber type electrolytically reduced water in the present invention means the alkaline reduced water generated in the cathode chamber (cathode chamber) of the three-chamber type electrolyzed water generator.

A three-chamber type electrolyzed water generator has been conventionally known (see, for example, Patent Documents 3 to 5), and its basic structure is purified water, raw water which is pure water, sodium chloride dissolved in this raw water, or the like. An ion exchange membrane and a cathode are arranged as a partition between the intermediate chamber through which the supporting electrolyte of the above circulates and flows in and out, and positive ions are added to the supplied raw water by performing electrolysis in the intermediate chamber. An ion exchange film and an anode are arranged as a partition between the cathode chamber and the intermediate chamber where the reduced water is generated, and the raw water supplied by supplying the supporting electrolyte to the intermediate chamber and performing electrolysis. It is composed of an anode chamber in which negative ions are dissolved and oxidized water is generated.

The three-chamber type electrolyzed water generator adds an electrolyte containing ion species according to the application to the intermediate chamber, and only the ions electrolyzed in the intermediate chamber have positive ions in the cathode chamber on the cathode side and negative ions in the anode chamber. It is drawn into the side anode chamber. Only pure water is supplied to the cathode chamber and the anode chamber, and the ions generated by the electrolysis of the electrolyte added to the intermediate chamber dissolve in the cathode chamber and the anode chamber, and each of them is functional electrolyzed water, reduced water and oxidation. Water is produced.
In the 3-chamber type electrolytic water generator, the electrolytic efficiency is increased, so that the water bond is broken, the surface tension is lowered, and the permeability is increased. Therefore, when sodium chloride is added as an electrolyte, the reduced water on the cathode side is highly washed. It brings about an effect, and the oxidized water on the anode side brings about a bactericidal effect at a low concentration, and this effect varies depending on conditions such as pH, ionic species, and water temperature.

In the gel-like cleansing cosmetic of the present invention, as the main raw material water of the aqueous gel, alkaline 3-chamber type electrolytically reduced water is mixed with water generated in the anode chamber of the 3-chamber type electrolytic device or acidic oxidized water. Is preferable. Not only is it provided with bactericidal, sterilizing and skin regeneration effects by oxidized water, but by lowering the overall pH, the storage stability of the gel-like cleansing cosmetics is increased and the irritation to the skin is reduced. The weight ratio of the oxidized water to be mixed with the reduced water is 0 to 30 parts by weight, preferably 5 to 30 parts by weight, more preferably 10 to 30 parts by weight, and 20 to 30 parts by weight with respect to 100 parts by weight of the reduced water. Is even more preferable.

In the production of the three-chamber type electrolyzed water used for the gel-like cleansing cosmetic of the present invention, any of the conventionally known three-chamber type electrolyzed water generators can be used.
