100% nicotine liquid refers to a solution containing nicotine as the sole active ingredient, without any dilution or additional substances. This highly concentrated form of nicotine is often used in the manufacturing of e-liquids for electronic cigarettes and vaping devices. Due to its potency, 100% nicotine liquid should be handled with extreme caution and stored securely to prevent accidental ingestion or exposure. Proper safety measures, such as wearing protective gloves and eyewear, should be followed when handling this substance. Additionally, accurate measuring and mixing techniques are crucial to ensure the safe and effective use of 100% nicotine liquid in e-liquid formulations.
