Description

  The present invention relates to electrolyzed water and a composition containing electrolyzed water as a main component, and more particularly to a cosmetic and a dentifrice containing electrolyzed water as a main component.

  Electrolyzed water obtained by electrolyzing water is divided into two types, acid water and reduced water (alkali ion water), and is widely used according to the respective characteristics. For example, acidic water is used as an astringent lotion because it has the effect of tightening pores. Reduced water is used as a cleaning agent because it has a cleaning action to remove dirt (see Patent Document 1), and is used as an alkaline ionized water for beverages because it has an effect of removing active oxygen in the body. Yes.

However, there was no idea of applying strong alkaline ionized water to the skin. The reason is that, as described in Patent Document 1, reduced water having a high reducing power with a pH of 8 or more and an oxidation-reduction potential (hereinafter referred to as ORP value) of −1000 mV is usually a strong alkaline detergent. Because it is a powerful substance that could remove blood that had adhered to clothes and solidified, which could not be removed without using it, there was a risk of adverse effects on the skin. There is a so-called “weakly acidic myth” that a pH comparable to the pH of this product is good, and it has been considered that a new effect could not be considered for alkaline cosmetics. Therefore, cosmetics using strong alkaline reduced water have not been present.
JP 2000-114733 A

  As described above, if the reducing water described in Patent Document 1 is used in cosmetics and dentifrices, there is a risk that the reducing power will be too strong and the skin may be damaged, and the conditions under strong reducing power (strong alkaline conditions) ), It is difficult to think that it is possible to maintain the moisture and fat stability by adding a surfactant as in conventional lotions and emulsions. On the other hand, since a preservative is added to conventional cosmetics and dentifrices, there is also a problem that safety is not sufficient.

  The present invention has been made in view of the problems as described above. By reducing the ORP value of reduced water having a high pH and weakening the reducing power, the skin irritation is remarkably reduced, and the viscosity of the reduced water is low. An object of the present invention is to provide a cosmetic and dentifrice that has a high moisturizing effect and a high degreasing effect and does not require preservatives.

  More specifically, the present invention provides the following.

  (1) It consists of electrolyzed water having a pH of 11 to 13, an oxidation-reduction potential of −30 mV to −280 mV, more preferably −16 mV to −128 mV, and a thickener, and has a viscosity of 2000 mPa · s to 10000 mPa · s. Cosmetic gel.

  According to the invention of (1), since the bactericidal effect is enhanced by changing the pH of the electrolyzed water from 11 to 13, the skin surface is sterilized and the face mites (Demodex) living in the pores are killed. Is possible. Moreover, since it has a degreasing action, dirt due to excessive sebum can be removed, so that the effect of decomposing the sebum stuck in the pores and tightening the pores can be expected. Moreover, since bacteria are not generated under such a high pH, a highly safe cosmetic that can be stored for a long time without adding a preservative can be produced. Moreover, the burden on the skin can be reduced by changing the oxidation-reduction potential of the electrolyzed water from −30 mV to −280 mV. Furthermore, by adding a thickener to make the gel at a room temperature of 2000 mPa · s to 10000 mPa · s (hereinafter, all referred to as a viscosity at room temperature), it may flow when applied to the skin or immediately Since it becomes possible to prevent evaporating, moisture retention becomes high. In addition, a fast-acting effect was confirmed. In particular, when used for an ultrasonic facial device, this effect can be obtained higher. Since a preservative and other additives are added to conventional ultrasonic gels, some people may cause rough skin if they are not carefully washed after use. In addition, if the gel is dried while attached to the face, it will look like a paste and the makeup will not be good. However, since the invention of (1) is strongly alkaline, it is effective in removing facial keratin and sebum, and since it is not acidic, there is no possibility of corroding the facial device.

  (2) The cosmetic gel for face according to (1), wherein the viscosity of the cosmetic gel is from 14000 mPa · s to 7000 mPa · s.

  (3) The cosmetic gel for body according to (1), wherein the viscosity of the cosmetic gel is from 3000 mPa · s to 5000 mPa · s.

  (4) The cosmetic gel according to any one of (1) to (3), wherein the thickener is hydroxyethyl cellulose.

  According to the invention of (4), by using hydroxyethyl cellulose as the thickener, it is possible to provide a gel that is harmless and well-familiar to the skin without changing the pH of the electrolyzed water. This gel can also be suitably used for an ultrasonic facial machine.

  (5) Consists of electrolyzed water having a pH of 11 to 13, an oxidation-reduction potential of −30 mV to −280 mV, more preferably −16 mV to −128 mV, and a thickener, and a viscosity of 2000 mPa · s to 3000 mPa · s. Dentifrice that is.

  According to the invention of (5), since the bactericidal effect is enhanced by changing the pH of the electrolyzed water from 11 to 13, it can be used as a dentifrice capable of killing the causative bacteria of dental caries. This dentifrice is preferably for an ultrasonic toothbrush or an electric toothbrush.

  (6) The dentifrice according to (5), wherein the thickener is hydroxyethylcellulose.

  According to the invention of (6), it is possible to provide a dentifrice with a good feeling of use without lowering the pH of the electrolyzed water by using hydroxyethyl cellulose as the thickener.

  According to the cosmetic gel and dentifrice of the present invention, it is possible to suppress irritation to the skin by lowering the ORP value. As a result, cosmetics and dentifrices that retain the properties of reduced water can be provided.

  The present invention will be described in detail below.

  The cosmetic gel of the present invention comprises electrolyzed water and a thickener. The “electrolyzed water” refers to water obtained by electrolyzing water using an electrolyzer, and particularly alkaline reduced water in the present invention. The pH of the electrolyzed water is preferably 11 to 13, and more preferably 12.3 to 12.9. Moreover, it is preferable that the oxidation-reduction potential at this time is −30 mV to −280 mV.
