Have you ever heard of electrolyzed water and wondered how long it can last? Well, you’ve come to the right place! In this article, we’ll take a look at the shelf life of electrolyzed water and how long it can maintain its effectiveness.
Electrolyzed water, also known as EOW, is generated by passing an electric current through water containing salt. This process creates a powerful oxidizing agent that has been found to be effective in killing bacteria, viruses, and other pathogens. But as with any other solution, the effectiveness of EOW diminishes over time.
The shelf life of EOW depends on multiple factors such as the type of water used, pH levels, and storage conditions. Generally, EOW can maintain its effectiveness for up to 3 days if stored in a closed container in a cool, dry place. However, its shelf life may decrease if exposed to sunlight or air. That’s why it’s important to store EOW properly to ensure its effectiveness over time. Let’s dive a bit deeper into these factors and how they affect the shelf life of EOW.
What is electrolyzed water?
Electrolyzed water is a type of water that has undergone an electrical process known as electrolysis. During this process, an electrical current is passed through a solution of saltwater, separating it into two separate streams of water – one that is highly alkaline and the other that is highly acidic.
The alkaline water produced during electrolysis is called Electrolyzed Reduced Water (ERW) while the acidic water is called Electrolyzed Oxidizing Water (EOW).
Uses of electrolyzed water
