Can the purchased e-liquid be diluted by oneself

You can dilute the purchased e-liquid by yourself. The commonly used dilution materials are glycerol (PG) and glycerol (VG), and the ratio is adjusted according to personal preference. For example, mixing e-liquid with VG in a 1:1 ratio can reduce throat sensation and increase smoke volume. During operation, an electronic scale should be used to ensure accurate mixing, and after mixing, it should be left to stand for 24 hours to blend the flavors.
Materials and tools for diluting e-liquid

The most commonly used dilution materials in the process of diluting e-liquid include glycerol (PG) and glycerol (VG). These two substances are the basic components of e-liquid, responsible for transmitting taste and generating steam, respectively. The content of PG directly affects the throat sensation and taste clarity of smoke, while VG determines the intensity and cloud effect of smoke. Normally, the PG and VG ratio of e-liquid is 50:50, but according to personal preferences, the density and throat sensation of the smoke can be changed by adjusting the ratio. When diluting e-liquid, increasing VG can result in thicker smoke, while increasing PG can enhance throat sensation and taste.
Regarding cost, the average price of 100ml PG and VG is approximately between 15 and 30 RMB, depending on brand and quality. Choosing food grade materials can ensure the safe use of diluted e-liquid.

Diluting e-liquid requires tools for accurate measurement and mixing of materials. The most basic tools include electronic scales, measuring cylinders, stirring rods, empty bottles, and fine mouthed funnels. The electronic scale is used to accurately measure the weight of PG, VG and essence to ensure the accuracy of the ratio, which usually needs to be accurate to 0.01g. Measuring cylinders and fine funnels are used to transfer liquids, reduce waste, and maintain cleanliness in the work area. The stirring rod is used to evenly mix all ingredients, ensuring the consistency of the diluted e-liquid. For empty bottles, dark glass bottles are usually chosen to prevent light from affecting the quality of e-liquid.
In terms of cost, the price of a basic dilution tool (including electronic scales, measuring cylinders, stirring rods, fine mouthed funnels, and empty bottles) is approximately 50 to 100 RMB. This investment is very cost-effective compared to long-term homemade e-liquid, as it not only controls costs but also allows for the free mixing of fragrance and concentration according to personal preferences.
Steps and methods for diluting e-liquid

Before starting to dilute e-liquid, ensure that all materials and tools are ready. This includes purchased e-liquid, dilution materials (PG and VG), calculated dilution ratios, and necessary tools (electronic scales, measuring cylinders, stirring rods, empty bottles, and fine mouthed funnels). Cleaning and disinfecting all tools is crucial to avoid contamination and ensure the purity of diluted e-liquid. Tools can be easily disinfected with 75% alcohol.

Calculate dilution ratio: Based on personal preferences and the concentration of the original e-liquid, calculate the amount of PG and VG to be added. Assuming the goal is to dilute 10ml of e-liquid to a nicotine concentration of 6mg/ml, and the crude oil concentration is 18mg/ml, then 20ml of PG/VG mixture needs to be added.


Adding e-liquid: Slowly add the original e-liquid to the mixed PG/VG, and gently stir with a stirring rod while adding to ensure that all ingredients are evenly mixed.
Quiet: Place the mixed e-liquid in a cool place and let it stand for 24 hours to allow the bubbles to naturally dissipate, ensuring that the flavors are fully integrated.

The diluted e-liquid should be stored in a dry, cool, and dark place, preferably using colored glass bottles to reduce the impact of light and oxygen on the quality of e-liquid. Marking the dilution date and concentration on the bottle is very helpful for tracking and managing homemade e-liquid. Normally, properly stored e-liquid can be stored for 6 months to 1 year. Gently shake the bottle before use to ensure even mixing of the liquid.
Precautions for diluting e-liquid

When selecting materials for diluting e-liquid, it is crucial to pay attention to the quality of the materials. When choosing glycerol (VG) and glycerol (PG) as diluents, it is essential to choose food grade or higher standard products. Food grade PG and VG ensure the safety of diluted e-liquid for the human body. In addition, for users who want to add extra flavor, it is also very important to select qualified food grade essence to avoid introducing harmful substances.

The safety of operation cannot be ignored in the process of diluting e-liquid. Using personal protective equipment, such as gloves and glasses, can prevent diluted materials from coming into contact with the skin or eyes, thereby avoiding potential irritation or injury. During the operation, ensure that the working environment is well ventilated and avoid inhaling steam or dust. In addition, strictly follow the dilution ratio for operation and avoid using any non recommended materials that may cause chemical reactions to prevent unsafe chemical changes.

The correct dilution ratio calculation is crucial for ensuring the quality and user experience of e-liquid. The calculation of dilution ratio needs to be determined based on the nicotine concentration of the original e-liquid and the final concentration expected by the user. For example, if you want to dilute a 10ml, 18mg/ml bottle of e-liquid to 6mg/ml, the user needs to add 20ml of PG/VG mixture to achieve a total volume of 30ml. It is important to remember that the diluted nicotine concentration is the result of the ratio of the original concentration to the added non nicotine butyl solution.
