Electrolytic-reduction ion water protects keratinocytes from hydrogen peroxide through radical scavenging activity and induction of AQP3 expression.

Skin exposed to ultraviolet light produces hydrogen peroxide (HO) and reactive oxygen species (ROS) that cause protein denaturation and other disorders. We investigated whether electrolytic-reduction ion water (ERI), which has reducing properties and has been reported to protect skin, exhibits antioxidant activity in skin keratinocytes. The antioxidant activity of ERI was first examined using DPPH assay and Electron Spin Resonance to test for radicals, and using the Amplex Red method to test for HO.

Single intratracheal administration toxicity study on safety of vapor inhalation of electrolyzed reduced water in rats.

The effects of acute intratracheal administration of electrolyzed reduced water (ERW; alkaline electrolyzed water) were investigated in rats. In this study, no deaths or near-deaths were recorded in either group, namely those treated with ERW or purified water (maximum doses of 900 mg/kg). The main symptoms observed in the rats were decreased spontaneous movements and abnormal breath sounds, which were considered to be transient symptoms caused by intratracheal administration.

Physicochemical properties and detergency of special electrolytic-reduction ion water.

The detergency of special electrolytic-reduction ion water (S-100) was evaluated in comparison with typical synthetic surfactants. Furthermore, to examine the cleaning mechanism of S-100, various physicochemical characteristics of S-100 were measured and a comprehensive evaluation of cleaning was performed. S-100 (10%) had a detergency comparable to that of various surfactants, such as sodium dodecyl sulfate and sodium dodecyl benzene sulfonate, which are generally blended or mixed in residential detergents.

Electrolytic-reduction ion water induces ceramide synthesis in human skin keratinocytes.

Ceramides play a critical role in the skin barrier. We previously demonstrated that electrolytic-reduction ion water (ERI) improves skin integrity and enhances the protective barrier function of the epidermis. Here, we first examine the effect of ERI on the expression of ceramide synthesis-related enzymes in human skin keratinocytes.

Antiviral effect of electrolyzed reduced water on SARS-CoV-2.

The inhibitory activity of electrolyzed reduced water (ERW) against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which is the etiological agent responsible for coronavirus disease 2019 (COVID-19), was tested in vitro on Vero E6 cells using a plaque assay. Infectious virus titers of cells treated with ERW 100%, 50% and 33.3% solutions and phosphate buffered saline (PBS, negative control) and exposed to the virus suspension for 60 seconds were 2.

Preparation and physicochemical properties of surfactant-free emulsions using electrolytic-reduction ion water containing lithium magnesium sodium silicate.

Surfactant-free emulsions by adding jojoba oil, squalane, olive oil, or glyceryl trioctanoate (medium chain fatty acid triglycerides, MCT) to electrolytic-reduction ion water containing lithium magnesium sodium silicate (GE-100) were prepared, and their physiochemical properties (thixotropy, zeta potential, and mean particle diameter) were evaluated. At an oil concentration of 10%, the zeta potential was ‒22.3 ‒ ‒26.

The treatment effect of the burn wound healing by electrolytic-reduction ion water lotion combination therapy. Part 2: Two degree burn of forearm to the dorsum of the hand.

Patient 1: A 1-year-and-3-month-old boy suffered a burn injury extending from the left forearm to hand due to boiling water. An extensive skin defect from the left forearm to the dorsum of the hand was observed, and an IIb-III degree burn was diagnosed. Treatment of the burn was started with the application of electrolytic-reduction ion water (ERI) lotion, antibiotic/steroid combination ointment, and vitamin A/E ointment with wrap therapy.

The healing effect of electrolytic-reduction ion water on burn wounds.

We prepared a lotion using electrolytic-reduction ion water (ERI), and evaluated the healing effects of this lotion (ERI lotion) on burn wounds. Third degree burn wounds were induced in the mouse dorsal skin, and ERI lotion or physiological salt (PS) lotion was applied to the wounds from immediately after injury [ERI (+) group and ERI (-) group as a control group, respectively]. The burn wound area was measured, and its serial changes were evaluated.

The treatment effect of the burn wound healing by electrolyticreduction ion water lotion.

A 2-year-and-4-month-old girl suffered a burn to the neck due to boiling water. She was examined at another hospital, and recommended to undergo dermatoplasty. Thirteen days after injury, she consulted our hospital.

Physicochemical properties of magnesium aluminum silicate (smectone) gels prepared using electrolytic-reduction ion water (2): Effects of various salts on the phase diagram.

We produced gels using electrolytic-reduction ion water and magnesium aluminum silicates (smectone), and evaluated in detail gel properties in the presence of various types of salt (NaCl, KCl, CaCl(2), MgCl(2), and AlCl(3)). Each salt was added to deionized-distilled water or electrolytic-reduction ion water, and phase diagrams for the smectone concentration (2.0-4.
