Abstract

PROBLEM TO BE SOLVED: To improve surface activity by using purified water, treating the water with magnetic fluxes, and controlling the surface tension to be a specified value or lower. SOLUTION: At first, purified water is produced. As a method for purifying water, for example, an ion exchange method may be employed but the method is not restricted. Magnetic flux treatment, weak current treatment, high voltage treatment, etc., may be employed solely or in combination with one another as the treatment method of the water. Magnetic flux treatment, for example, is normally carried out by passing water at a specified flow speed or higher through a gap between permanent magnets or electromagnets having magnetic field strength about 0.07T(tesla) or higher. Water having surface tension at least 72.8dyn/cm<-1> , that is 71dyn/cm<-1> , 70dyn/cm<-1> , preferably 68.8dyn/cm<-1> or lower than these values can be obtained by treating the purified water by such a method. Consequently, the obtained water has improved surface activity due to the low surface tension and can be used as a substitute of a surfactant or used together with another surfactant.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to water having excellent surface activity and a composition containing the water.

[0002]

2. Description of the Related Art Water is an important substance used in various industrial fields. In the fields of food, medicine, cosmetics, detergents, etc., water is often used as a solvent. However, when a substance having low solubility in water is dissolved in water or an emulsion is produced, it is often necessary to use a water-soluble solvent or use a surfactant at the same time. Particularly, in the fields of the above-mentioned foods, pharmaceuticals, cosmetics, and the like, it is often not preferable to add a surfactant because safety issues arise. Also,
It may be desirable that other than these food, pharmaceutical or cosmetic compositions not contain a surfactant from the viewpoint of safety or the use of the composition. In these fields, it is thought that by using water having excellent surface activity, the components of the composition are retained with a sufficient affinity, so that a composition having excellent stability can be obtained.

[0003] Therefore, it is desired to produce various compositions without using a surfactant as much as possible.

[0004] By the way, conventionally, various treatments have been disclosed for treating water to obtain water having small clusters. Japanese Patent Application Laid-Open No. Hei 4-235904 discloses a specific treatment in ¹⁷ O-NMR measurement. It is disclosed that when the water in the range is used for lotion, the water has a moisturizing effect. However, there is no report that attempts have been made to improve the surface activity of water and use it in various compositions.

[0005]

SUMMARY OF THE INVENTION In the industry where water or a surfactant is used, the present inventors have produced various compositions by suppressing the use of a surfactant as much as possible or without using a surfactant. As a result of intensive studies, it was found that by using water having a surface tension of 72.8 dyncm ^-1 or less, for example, a surface tension of 68.8 dyn
The water of dyn · cm ⁻¹ was found to hold three times as much oil as ordinary tap water, and completed the present invention.
The water of the present invention is excellent in surface activity as a result of reduced surface tension, so in a composition requiring a surfactant, water can be used in place of the surfactant, or
The use of surfactants can be reduced.

[0006]

The water comprises two hydrogen and one oxygen.
Individual molecules form a group by an electric force (hydrogen bond between oxygen and hydrogen) acting between the molecules. This group is called a cluster, and at least five or more molecules form a cluster.

[0007] The inventors of the present invention have considered that water having small clusters has a small surface tension, and have thought of reducing the size of the clusters, thereby completing the present invention.

[0008] The small water in the cluster exists widely in nature, such as hot spring water, snowmelt water, and groundwater. Water with small clusters can also be produced by chemically treating with an acid, an alkali or the like. However, these waters do not have sufficiently small clusters and consequently do not have low surface tension. Therefore, some processing is required to further reduce the cluster. Purified water, tap water, etc. as referred to in the Japanese Pharmacopoeia can also be suitably used to obtain water having a desired surface tension.

The present inventors have found that by further treating the above-described various types of water, the clusters can be made as small as possible, and the surface tension of the water can be reduced, thereby producing a surfactant effect. Was completed. As described above, it has been found that, even if the water contains impurities, by performing some kind of treatment, the water cluster can be reduced, and the surface activity of such water dramatically increases. Is significant.

DETAILED DESCRIPTION OF THE INVENTION The water of the present invention having a surface tension of less than 72.8 dyn.cm ^-1 can be produced as follows. First, purified water is prepared. As a method for purifying water, for example, techniques known to those skilled in the art such as an ion exchange method, electrodeionization using an ion exchange membrane, and distillation can be used.
It is not limited to these. Purified water referred to in the Japanese Pharmacopoeia can also be suitably used. The purified water may be prepared before the purified water treatment described below, or may be performed in parallel with the purified water production treatment.

The method for obtaining water having a surface tension of less than 72.8 dyn · cm ^{−1 according} to the present invention, that is, the method for treating water includes a magnetic line treatment, a weak current treatment, a high voltage treatment, a ceramic plate treatment, and a far infrared treatment. Any of high frequency (electromagnetic wave) treatment, mechanical treatment, ultrasonic treatment, electrolysis treatment, electromotive force treatment, laser beam treatment, chemical treatment or natural ore treatment can be performed alone or in combination. The water used is preferably purified water.

The magnetic field line treatment is usually performed by passing water at a fixed flow rate or higher through a permanent magnet having a magnetic field strength of about 0.07 T (tesla) or more, or a gap between electromagnets. The treatment is preferably performed with a line of magnetic force of 0.3 T or more. In particular, 1.2T or more is preferable. Note that 1T (Tesla) is 10,000 gauss.

The weak current process is performed by flowing water into the gap between the non-insulated internal electrode and the external electrode, and passing a weak current of several tens of milliamps.

The high voltage treatment is performed by applying a DC or AC voltage of 1,000 volts or more to the water in the water tank. In order to increase the electric conductivity, for example, charcoal or the like can be immersed.

The wavelength of the ceramic plate treatment is 6 to 14 μm.
In this method, a ceramic plate made of a material emitting far infrared rays is immersed in a water tank.

The far-infrared treatment includes a method of passing through a ceramic filter that emits far-infrared rays, and a method of applying the output from a far-infrared heater to water. The method of passing through a ceramic filter is almost the same as that of the ceramic plate processing.

High frequency (electromagnetic wave) processing is a method in which a higher frequency than ultrasonic waves is applied to water. Microwave processing such as a microwave oven is applicable.

The mechanical treatment is a method of rotating water at high speed.

The ultrasonic treatment is a method of applying ultrasonic waves having a frequency of about 20 to 40 KHz to water. Either a high output used for cleaning jewelry or glass utensils or a low output which promotes aging of sake can be used.
