Essential oils are cherished for their aromatic and therapeutic properties. However, their interaction with materials like plastic remains a question.
Keep reading to find out whether essential oils can break down plastic bottles and learn tips for safe storage and usage.
So, Do Essential Oils Break Down Plastic Bottles?
The answer is not a simple yes or no. It depends on the type of plastic used. Essential oils can sometimes cause the plastic to weaken or even break down.
Not all plastics are the same, and some can better withstand the strong effects of essential oils.
Why Do Essential Oils Break Down Plastic?
Since essential oils are highly concentrated, they may break down or dissolve plastic containers over time. It causes leaks and the loss of precious oils.
For example, citrus oils like lemon oil are so potent that if left in certain plastic bottles, they can eat away at the plastic.
You can use plastic bottles, but be very sure of how long you want to store your essential oil blend.
Essential Oils vs. Plastic Bottles
Essential oils can cause more damage to thinner plastic, which is more vulnerable. Oils are made up of tiny molecules that can penetrate plastics and break the bonds that hold them together.
On the other hand, thicker plastics have stronger bonds and longer chains that can resist the oil’s powers better.
That’s why knowing which plastics are safe to use with essential oils is important.
Type Of Plastic Safe To Store Essential Oils
Many types of plastic are available, each with different components. Only high-quality plastic bottles are safe for storing essential oils, which are as below:
HDPE Plastic
High-density polyethylene (HDPE) is a high quality plastic known for its durability. It is categorized as Plastic Number 2
When using essential oils in plastic spray bottles, opt for bottles made of HDPE plastic. It makes sturdy containers for everyday items. It doesn’t easily crack or leak, keeping the contents inside safe.
After using a product, you can clean the HDPE container with water, which is ready to be recycled.
PET Plastic
Polyethylene terephthalate (PET) is a type of plastic commonly used to make disposable water bottles. It is considered safe for single-use storage.
PET is an excellent plastic option for storing, shipping, and selling essential oils. It’s not quite as durable as HDPE, but it’s resistant enough to break down and safely hold properly diluted essential oils.
Can We Store Diluted Essential Oils In Plastic Bottles?
Essential oils are diluted with multiple carrier oils to lower their strength and make them safe.
Diluted oils, unlike pure essential oils, can be stored securely in plastic bottles. For this purpose, you should only use TEP and HEDP plastic containers.
Safe Containers To Use With Essential Oils
Here are some safe containers to store essential oils:
It is advisable to store essential oils in glass spray bottles. They’re sturdy and don’t react with the oils.
Stainless steel containers do not affect the quality of oils. Unlike glass, stainless steel is highly durable and won’t break.
Aluminum containers are safe for essential oils when it comes to short-term storage. They ensure safe transportation.
Ways To Extend The Shelf Life Of Your Essential Oils
Here are some best ways to store essential oils properly:
Make sure your oils are stored in airtight containers. This will reduce the risk of oils evaporating and oxidizing in the air.
Keep essential oils in dark glass bottles. This helps block out damaging sunlight.
While oils may be stored in plastic, consider using only HDPE or TEP plastic containers.
Keep them away from direct sunlight or long periods of exposure to heat. This helps maintain their potency and aroma for as long as possible.
Summary
Now you know that essential oils, except HDPE and PET plastic, can break down plastic bottles.
As you are aware of the other safe options available, consider them to refrain from oil spills or bottle damage!
