Essential oils are concentrated liquids extracted from plant materials and are commonly used in aromatherapy, massage, and personal care products.

Production of essential oils: Essential oils can be extracted through various methods, with the most common method being distillation. In the process of distillation, plant materials with high volatility and low boiling points are typically used. During distillation, the plant materials are exposed to steam and heated, and the components with lower boiling points vaporize with the steam and eventually condense into essential oil in the condenser.

Some plants have high volatility and are suitable for extraction using the distillation method. Common plants suitable for distillation include peppermint, rosemary, lavender, thyme, neroli, fennel, and others. These plant oils can quickly evaporate during the distillation process and condense into liquid form through steam condensation.

However, not all plant oils are suitable for extraction through distillation. Some plant oils have less stable components that can easily decompose or lose their activity at high temperatures. For such plants, other methods such as cold pressing or solvent extraction are more appropriate.

In conclusion, essential oils suitable for the distillation method are those with high volatility and low boiling points, such as peppermint, rosemary, lavender, thyme, neroli, and others.

When selecting containers for essential oils, several factors need to be considered:

Material: It is best to choose containers made of dark-colored glass for essential oils. Dark-colored glass (such as purple, blue, or green) can prevent sunlight and other light sources from shining through, reducing the oxidation rate of the essential oil. Transparent glass containers or plastic bottles may not provide sufficient protection and may compromise the quality of the essential oil.

Sealing Performance: Ensure that the chosen container has good sealing performance. The essential oil container should be able to seal completely to prevent the volatilization of the oil and the entry of ambient air. This helps maintain the freshness and effectiveness of the essential oil.

Size: Select an appropriate container size based on your usage needs. If you are purchasing a small amount of essential oil for personal use, a bottle with a small capacity (typically 10 milliliters or smaller) may be sufficient. However, if you are buying a large amount of essential oil or intend to use it for commercial purposes, you may need larger capacity bottles.

Spray Bottles: If you plan to use the essential oil to make perfumes, cleansers, toners, etc., you can choose containers with spray nozzles for convenient use.
