Essential oils are natural plant and animal-based products that are commonly used for aromatherapy, skincare, and natural remedies. However, it is important to exercise caution when using essential oils with plastic containers as they can cause plastic to degrade, melt, or dissolve. This is because essential oils contain organic solvents that can soften or dissolve plastics, especially when the concentration of the oil is high. This is particularly true for hot oils, citrus oils, and potent oils like oregano and thieves essential oil blend. As such, it is recommended to always store essential oils in glass containers, preferably amber glass, or specialized plastic containers that are resistant to essential oil degradation, such as polypropylene plastic containers.

What You'll Learn
Plastic containers to avoid
Essential oils, especially potent ones like Thieves essential oil blend, oregano essential oil, and citrus oils, can dissolve plastic and eat away at the plastic lids. Therefore, it is best to avoid storing essential oils in plastic containers.
If you are adding essential oils to your water bottle, it is recommended to use a glass or stainless steel water bottle. Glass is impervious to essential oils and is easy to clean, requiring just water and soap to get the residual oils out. Amber-coloured glass bottles are also ideal for protecting the oils from light and preserving them for years.
If you are making room sprays or cleaning sprays, it is best to use stainless steel or glass spray bottles. While some high-quality plastics like High-Density Polyethylene (HDPE) can safely store diluted essential oils, it is crucial to ensure that the oils are properly diluted and that the plastic is of good quality to avoid any reactions or degradation of the oil.
Some other plastic types to avoid are polystyrene (plastic number 6), which is easily dissolved by d-limonene in lemon oil, and Polyethylene Terephthalate (PET) (plastic number 1), which is also resistant to essential oils.

Plastic containers to use
It is best to avoid storing essential oils in plastic containers as many oils will react with the plastic and degrade it. This is because essential oils can dissolve plastic, eating away at the plastic and causing deterioration.
However, there are some types of plastic containers that can be used to store essential oils. High-Density Polyethylene (HDPE) is a type of plastic that is not easily dissolved by essential oils. This is because it has stronger bonds and longer chain lengths that are not broken up by essential oils. Containers made of HDPE are often marked with the number 2 as their resin identification code. Another type of plastic that can be used is PET, or plastic number 1.
If you are unsure whether a plastic container is resistant to essential oils, you can test it by applying a drop of oil to the outside of the container and observing if there are any changes over a few minutes.
It is always safer to store essential oils in glass containers, preferably amber glass. Amber glass provides the greatest protection from the negative effects of light exposure, which can break down the aromatic properties and botanical constituents of essential oils. If you are concerned about using glass containers due to the risk of breaking, stainless steel containers are also an option.

How essential oils dissolve plastic
Essential oils can dissolve plastic, especially potent varieties like Thieves essential oil blend, oregano essential oil, and citrus oils. These oils can eat away at plastic and cause deterioration. This is because essential oils contain hydrocarbon non-polar organic solvents, which dissolve other non-polar molecules, such as plastic.
The extent of the damage depends on the type of plastic and the concentration of the oil. For instance, a plastic container may become cloudy, discolored, or brittle, and cracks may form. In some cases, the bottom of a plastic cup may fall out, as the plastic has been completely dissolved.
Some plastics, such as High-Density Polyethylene (HDPE), are more resistant to essential oils. This type of plastic is often used for the caps, diffusers, and drip stoppers of essential oil bottles. However, even these plastics will be affected over time, and it is recommended to always store essential oils in glass containers, preferably amber glass, to protect the oil and prevent any plastic contamination.
The potential for essential oils to dissolve plastic is a concern, especially considering the popularity of essential oils in aromatherapy, skincare, and natural remedies. It is important to select the right type of container to store essential oils and to be cautious when using essential oils with plastic products to avoid any unwanted damage or leaks.

Essential oils to avoid
Essential oils are natural plant and animal-based products with anti-inflammatory and antifungal properties. They are used for everything from aromatherapy and skincare to cleaning and lubrication. While they offer several benefits, caution is required when combining plastic and essential oils. Some essential oils can dissolve plastic, causing leaks, cracks, and contamination of the oils.
Citrus oils, in particular, are known to eat away at plastic and cause deterioration. This includes lemon, orange, and clove oils. Other essential oils that can have similar effects include peppermint oil, sweet fennel oil, coriander oil, and oregano oil.
To avoid issues with plastic containers, it is recommended to store essential oils in glass containers, preferably amber or dark glass to protect the oils from sunlight. If glass is not an option, stainless steel containers are also suitable for storing essential oils.
Some high-quality plastics, such as High-Density Polyethylene (HDPE) or Polyethylene Terephthalate (PET), are considered safe for storing essential oils. However, it is crucial to ensure that the oils are properly diluted and that the plastic is of good quality to avoid any adverse reactions or degradation of the oil.
Additionally, it is important to note that essential oils should be approached with caution when considering internal use. Some oils may be safe for consumption, while others may be toxic or harmful. Always research specific essential oils and consult a healthcare professional before ingesting them.

Effects of essential oils on the human body
Essential oils are highly concentrated plant extracts that are created by steaming or pressing various parts of a plant, such as flowers, bark, leaves, or fruits. They are known for their distinct fragrances and potential therapeutic benefits. However, it's important to understand their effects on the human body and the precautions necessary when using them.
When used correctly, essential oils can offer a range of benefits. Aromatherapy, for instance, is a form of complementary medicine that utilizes the scent of essential oils to promote health and well-being. Certain essential oils, such as lavender, are known for their calming properties, helping to reduce stress, anxiety, and improve sleep. Additionally, tea tree oil is often used for its antiseptic, antimicrobial, and antifungal properties, making it effective for treating acne, wounds, and insect bites.
Essential oils can also be applied topically to the skin, usually diluted with a carrier oil to avoid skin irritation. However, it's important to exercise caution as some individuals may experience allergic reactions, such as a red, itchy rash or hives. In such cases, it is advised to seek medical attention. Furthermore, ingesting essential oils is generally not recommended due to their high concentration and potential harmful effects.
While essential oils offer potential benefits, there are also considerations to keep in mind. Firstly, the quality of essential oils can vary significantly, and without proper regulation, the labels may not disclose all the ingredients. Additionally, prolonged or excessive use of essential oils can lead to a decreased effectiveness over time as the body may become accustomed to them. Therefore, it is recommended to use essential oils sparingly and not as a routine practice.
In summary, essential oils have the potential to positively impact human health and well-being when used appropriately. Aromatherapy and topical applications are common methods of utilization, offering benefits such as stress relief, improved sleep, and antiseptic properties. However, precautions such as dilution, avoiding ingestion, and being mindful of potential allergic reactions are crucial. As with any substance, using essential oils in moderation and consulting appropriate guidance or professionals is advised to ensure a safe and beneficial experience.
