Which Colored Glass Is Best for Essential Oils?

The essential oil industry is witnessing considerable growth with no signs of it slowing down any time soon. The industry is expected to grow at a CAGR of 8.6% over the next six years. The main reason for this uptick in growth is that essential oils are now being used in various industries all over the world ranging from pharmaceuticals to skincare.

Moreover, companies are now under more pressure than ever to reduce their use of plastic and opt for more sustainable practices. One aspect that has come under scrutiny is packaging, as plastic was the preferred option for most companies due to its cost-effectiveness even though it was harmful to the environment.

Due to increased pressure from consumers, we are now seeing essential oil manufacturers switch to glass packaging that includes amber glass jars and bottles.

Now that more manufacturers are opting for glass packaging, the question is: which colored glass is best for essential oils?

Colored glass–A potential difference-maker

As manufacturers, you continually need to strive to improve your offerings in order to keep things fresh for the consumer. Glass packaging has come as a blessing for essential oils consumers and manufacturers alike, because not only is it perfect for adding a layer of elegance to the product, but it also increases shelf life.

Colored glass packaging also protects essential oils from losing their potency, and getting contaminated. UV rays, in particular, pose a great threat for essential oils as overexposure can lead to oxidization of the contents and make them less effective.

Why amber glass

The primary reason why amber glass is ideal to use for packaging essential oils is that it ensures protection from harmful UV rays. These UV rays have the potential to impact essential oils in a manner that they lose their countless beneficial qualities.

Dark amber glass keeps out sunlight and maintains the quality of the contents stored within. This is also one reason which amber glass is often used for beer bottles.

Another benefit of amber glass is that it provides manufacturers the option of using a more sustainable option as a packaging solution without putting a strain on their financial budget. Boston round bottles are now commonly used to store essential oils by most companies.

However, consumers should be made aware that while amber glass does provide protection against UV rays, they should always store their essential oils in a cool location like the refrigerator to ensure maximum protection.

The negatives of blue, green and clear glass

Even though green and blue glass are perfect for making the product stand out from the competition, it doesn’t protect the contents in an effective manner compared to amber glass.

Blue and green glass protects essential oils from the visible light but is unable to prevent UV rays from impacting the potency of the oils. On the other hand, clear glass doesn’t offer any light protection, putting the oils at a high risk of oxidization.
