👉 Hygenics are a type of liquid that is composed entirely of hydrogen atoms. They are often used in various applications, such as fuel and lubrication systems. The term "hygenics" comes from the Greek word "hylēs," which means "water." In chemistry, hydronium ions (H+), or water molecules (O2-), are commonly found in these substances. Hygenics can also be used for other purposes such as lubrication and fuel.
