FAQ'S
It is the water with pH 9-10 obtained from drinking waters by the electrolytic reaction at the cathode of the alkaline ionized water apparatus (water electrolyzer for home-use).
Compared to tap water, alkaline ionized water has a higher content of hydroxide ion (OH-) and cations such as calcium, magnesium, etc. At the same time, hydrogen gas (H2) is also produced as nano-sized bubbles.
If the whitish turbidity disappears when the cup is left alone for a little while, then the whitish turbidity is due to hydrogen gas generated during electrolysis or to the mixture of air into the water inside the apparatus. Therefore, there is no problem.
If the whitish turbidity does not disappear even when left alone for a little while, then it may be due to the adhesion of calcium. If that is the case, it may be necessary to clean the apparatus, etc. Please contact the customer service department of the apparatus maker.
pH is the index indicating the degree of alkalinity or acidity. The pH value is expressed by a figure from 0 to 14 indicating the concentration of hydrogen ion (H+) in the water according to the following equation: pH = -log [H+] Values near pH7 are neutral, and as the values become closer to 14 they become more strongly alkaline. On the other hand, as the values become closer to 0 they become more strongly acidic.
Alkaline ionized water contains hydroxide ion (OH-), cations (calcium ion, etc.) and hydrogen (H2) due to electrolysis.
According to proven research reports , strongly electrolyzed water contains “activated hydrogen” competent for the elimination of reactive oxygen.
Almost all types of alkaline ionized water producing apparatus can purify tap water since they contain a water purifier competent for eliminating residual chlorine or chlorine odors. In addition, alkaline ionized water has been evaluated to be tasty and easy to drink.
According to proven research reports , strongly electrolyzed water contains “activated hydrogen” competent for the elimination of reactive oxygen.
Alkaline ionized water has slightly increased water hardness due to electrolysis Therefore, alkaline ionized water is also soft water. (Although there is no clear definition, total hardness of around 100 mg/L – 200 mg/L is termed soft water.)
Firstly, it seems likely that your home tap water may be somewhat acidic.
Furthermore, if the tap water is rich in carbonate content, it may be difficult for the apparatus to produce normal alkaline ionized water.
We suggest boiling the generated water once in order to volatilize the carbonates. After letting it cool, measure the pH.
If the pH indicates alkalinity, it means regular electrolysis was performed by the apparatus.
Please adjust the electrolysis capability according to the instruction manual for the product, or contact the customer service department of the manufacturer.
In general, “oxidation” refers to the reaction of a substance with oxygen, and “reduction” refers to the reduction of oxygen of an oxidized substance.
Oxidation reduction potential is an index of the ratio of oxidized substances and reduced substances in a solution, and is indicated in units of mV (millivolts) or V (volts).
Drinking of alkaline ionized water has been verified to be effective for improving weak gastrointestinal symptoms (chronic diarrhea, hyperacidity control, indigestion, and abnormal fermentation in stomach and intestines).
Please note that acidic ionized water may be used for face washing but not drinking
Medical and scientific studies on alkaline ionized water from various viewpoints have been carried out and still are continuing. It was concluded that alkaline ionized water has the effect of improving abnormal bowel movement such as chronic diarrhea or constipation.
The pH of alkaline ionized water is 7.5 to 10.5. When it is subject to brewing tea, etc. or if it is long stored, the pH value tends to return toward neutral, so it is recommended that fresh alkaline ionized water should be drunk.
Please be careful of the following 3 points:
1.Please avoid taking medicines with alkaline ionized water and persons with achlorhydria should avoid drinking alkaline ionized water.
2.If you feel abnormal or strange after drinking or if there are no apparent improvement in symptoms despite continued drinking, please consult your doctor.
3.Persons with chronic symptoms or with weakened physical condition should consult their doctor before drinking alkaline ionized water.
Alkaline ionized water was approved under the Pharmaceutical Affairs Law in Japan for improvement of gastrointestinal symptoms such as chronic diarrhea,hyperacidity control, indigestion, and abnormal fermentation in stomach and intestines.
Although there are clinical facilities that are using alkaline ionized water for the purpose of treatment of diabetes or atopic dermatitis, such beneficial effects have not been approved.
How to drink alkaline ionized water
When you drink alkaline ionized water for the first time, set the pH around 8 to 8.5 and start with drinking a cup of the water in order to get your physical conditions used to it.
After about 2 weeks, gradually increase the pH and/or the drinking amount depending on your physical condition.
Continuous drinking of 500ml to 1 liter per day was scientifically demonstrated to be satisfactory to get the effects of the water.
For direct drinking, we suggest drinking of the fresh alkaline ionized water with pH ranging from 8.5 to 9.5.
For children or elderly people, alkaline ionized water with low pH (around pH8 to 8.5) should be used at first, and as they become accustomed to it the pH value may be gradually increased.
In addition, for neonates (up to around 1 year old), since they drink mother’s milk or milk, their intestinal movements are different from those of adults and so alkaline ionized water is not recommended.
However, when they start eating the same foods as adults, there would be no problems basically for them to drink alkaline ionized water.
For babies or neonates, we do not recommend alkaline ionized water since their intestinal movements are different from those of normal adults.
No reports of specific problems concerning this matter have been made so far. However, if there are any symptoms, please consult your doctor.
When consulting your doctor, please tell your doctor the following 3 points regarding alkaline ionized water:
- Improvement effects against gastrointestinal symptoms (chronic diarrhea, indigestion, abnormal fermentation in stomach and intestines, acid control, and acid indigestion) have been approved for alkaline ionized water.
- It is a weakly alkaline water obtained by electrolysis.
- The contents of minerals such as calcium, magnesium, etc. are higher than those of tap water.
Unlike acid-control medicines, the acid controlling capability of alkaline ionized water is extremely mild so that it is hard for the water to neutralize stomach acids to cause harmful effects.
Alkaline ionized water does not show any immediate effect but a protective slow effect by continuing constant drinking. In addition, there have been so far no reports of physical problems occurring when it was drunk by a healthy person.
For drinking down medicines, purified water should be used. Since alkaline ionized water itself has approved beneficial effects, its use with other medicines should be avoided.
Normally, aluminum products have undergone aluminum processing (anti-corrosion treatment). If the aluminum processed has worn off for some reason, the aluminum substrate becomes exposed and discolorates.
When alkaline ionized water is used with aluminum containers of which aluminum substrate is exposed, precipitation of white aluminum hydroxide may occur. In some cases, the containers may become spotty.
When the aluminum hydroxide is heated, an oxidized aluminum membrane may be formed and become black. (This phenomenon also occurs with tap water, but the alkalinity tends to make the process progress more quickly).
Since the blackened area is an oxidized aluminum membrane, the aluminum containers can be used as ever without problem.. However, since holes may be formed in the exposed aluminum substrate, we recommend using containers made of a different material (e.g. stainless steel).
The white substance stuck to the bottom is mostly calcium components that come from tap water. The same phenomena may occur even when intact tap water is used, although the formation of the precipitated substance is more remarkable with alkaline ionized water because it has markedly higher content of minerals such as calcium..
The calcium components stuck can be removed using citric acid (food additive available at pharmacies) or a commercial pot cleaner.
When the cleaner t is used, please follow the instruction manual. Periodical cleaning is recommendable. (This cannot be used for aluminum pots.)
Alkaline ionized water apparatus produces alkaline ionized water at the cathode side and acidic ionized water at the anode side at the same time. The acidic ionized water has been known to have an astringent effect so that the water can be used for face-washing or washing dishes, etc.
Please note that disinfection effect on athlete's foot or injuries cannot be expected for acidic water.s foot or injuries are not approved for acidic water produced by alkaline ionized water apparatus.
Please be careful of the following 2 points:
- Persons with delicate or allergic skin should consult their doctor or pharmacist before using acidic ionized water.
- If your skin feels abnormal when acidic water is used, stop using immediately and consult your doctor.
What is the difference between acidic ionized water and “strongly acidic electrolytic water” which is used for disinfection?
"Strongly acidic electrolyzed water" is acidic (pH <2.7 or lower) aqueous solution containing hypochlorous acid which is electrolytically generated from a dilute (<0.2%) saline solution (sodium chloride with purity of 99% or higher) by a specific type of electrolysis apparatus.
Strongly acidic electrolyzed water was developed in Japan in the late 1980's as disinfectant water. Strongly acidic electrolyzed water-producing apparatus was approved as a medical device for "hand-washing upon surgery" in 1996 and for "antiseptic washing and disinfection of endoscopes" in 1997.
Acidic ionized water and strongly acidic electrolyzed water are different from each other in terms of the electrolysis condition, properties and beneficial effects.
