iPOSH is manufactured using a completely new and innovative approach compared to conventional methods of manufacturing hypochlorous acid (weakly acidic), based on a patented technology (ion-exchange method) with strict quality management standards at factories that are approved for manufacturing cosmetics (*1) and food additives (*2).
*1: Akita Factory *2: Yuzawa Factory

The ion exchange method filters impurities such as calcium and magnesium that occur in the raw materials, and prevents the creation of sodium chloride (salt) through a neutralization reaction. The end result is high-purity hypochlorous acid (weak acidity).
In addition, the filtering action of the weakly acid ion exchanger stabilizes the pH in the weak acid range of 6 to 6.5. Through adoption of this innovative manufacturing technology and high-quality production standards, the key product characteristic of iPOSH is that the efficacy of the active ingredient is retained for more one year after manufacture.
