Carrier Oil

Carrier oils are an important part of making essential oil capsules. Because if essential oils are in high concentrations, they may cause strong effects or even be harmful. Carrier oils dilute essential oils to a safe level for consumption. Besides, they help stabilize essential oils, preserve their benefits, and extend their shelf life. Common carrier oils include coconut oil and olive oil.

Dropper or Pipette

When making capsules with essential oils, you must have a dropper or pipette. This tool measures and transfers small amounts of liquid accurately. This ensures the correct dilution and oil dosage, making the essential oil effective. It also guarantees safety. Because some essential oils are very potent and can irritate the skin or mucous membranes if spilled.

Capsule Filling Machine

A capsule filling machine is a device designed to fill empty capsules with substances like liquid or powders. There are many types to choose from. They include manual capsule fillers, semi-automatic and fully automatic models. So they can meet different production needs.

If you want to make a small number of essential oil capsules, manual capsule fillers are a good choice. They are the cheapest but require more manual work. Semi-automatic ones offer a balance between cost and efficiency, suitable for medium-scale production. Fully automatic capsule filling machines are high-capacity machines designed for large-scale production. They handle the entire process from separating capsules to filling and sealing them. They are the most efficient but also the most expensive.

4 Steps of Making Capsules with Essential Oils

The process involves a few detailed steps to ensure they are effective, safe, and consistent. Here are some steps for your reference.


Before manufacturing, it is important to clean and disinfect the workplace thoroughly. You can wipe all surfaces with disinfectant to ensure the workspace is clean. Tools like droppers also need to be disinfected. It ensures no contaminants affect the purity and effectiveness of the essential oils. Also, it helps avoid introducing bacteria into the capsules.

More importantly, you should wear a sterilized apron and disposable gloves. This helps keep oils, dirt, and bacteria off your hands. It prevents them from contaminating the essential oils or capsules.

Mix the Essential Oils with Carrier Oil

You can use a dropper or pipette to measure the amount you need. Then mix accurately according to the ratio to achieve the desired dilution. A common ratio is 1:1. Next, find a container like a bowl to hold the mixture. Stir the mixture well to ensure it is fully combined.

Fill Capsules with the Mixture

If you use a semi-automatic capsule filler, first pour the empty capsules into the hopper. The machine will then place these capsules in a filling tray. You need to separate the capsule caps and bodies by hand. Next, put the mixture into the material storage bucket. You should place the empty capsule bodies under the filling mechanism. It will automatically fill the mixture into the capsules according to the dose you set. After filling, the locking mechanism is used to seal the capsule bodies and tops.

If you use a manual capsule filler, you need to do everything by hand. The processing time is also longer. Be careful not to spill any liquid when transferring and filling.


After filling, remember to check each capsule to make sure it is sealed well. A good-quality capsule will not leak and can protect the contents from air and moisture. Please note that place the capsules in a cool and dark place.

3 Considerations when Making Essential Oil Capsules

Select the Right Capsule Sizes

When you prepare to make essential oil capsules, it is important to calculate the total volume of the oil mixture. Because it helps you choose the right capsule size to ensure each one comfortably holds the content.

The most used capsule sizes include size 00 and size 0. Size 00 capsules are slightly larger, holding about 0.95 milliliters. This is a good choice for higher doses of essential oils. However, because they are larger, some people might find them harder to swallow.

Dose Control

The effectiveness of essential oils is closely linked to the dosage. Fewer dosages may not give the desired results, while more content can increase the risk of allergic reactions, like rashes. Therefore, it's important to choose the right amount to achieve the desired effect.

If you are not sure how to choose the dose, you can check recommendations from authorities. Organizations like the National Association for Holistic Aromatherapy (NAHA) and the International Federation of Aromatherapists (IFA) provide valuable resources.

Clear Labels

It is key to label the production date, the type, and the ratio of essential oil mixtures. This is used to track the shelf life and product condition, ensuring safe use within the specified period. For commercial use, you need also to include usage instructions, dosage recommendations, and any relevant safety warnings.
