Pure liquid nicotine refers to nicotine in its liquid form without any additional additives or dilutions. It is commonly used in the production of e-liquids for electronic cigarettes and vaping devices. Pure liquid nicotine is highly concentrated and must be handled with caution due to its toxicity. It is typically stored in tightly sealed containers and should be kept out of reach of children and pets. When handling pure liquid nicotine, proper safety measures such as wearing gloves and protective eyewear are essential to prevent accidental exposure. Additionally, it is important to accurately measure and mix pure liquid nicotine when using it to create e-liquids to ensure safe and consistent vaping experiences.
