Should Oil Be Stored in Plastic Containers?

When it comes to storing oil, it’s important to consider the type of container you use. While plastic containers may seem convenient, it’s best to avoid storing oil in them. This is because plastic containers have the tendency to leach chemicals over time, which can ultimately affect the taste and quality of the oil.

Chemicals from the plastic can gradually seep into the oil, compromising it’s integrity and potentially altering it’s flavor. Moreover, these chemicals can also pose health risks if consumed. Therefore, it’s highly recommended to transfer oil from a plastic container to a glass one with a tight lid.

Glass containers aren’t only safer, but they also provide better preservation for oil due to their non-reactive nature. They don’t introduce any foreign chemicals into the contents, ensuring that the oil remains untainted.

A tight-fitting lid is also essential for maintaining the freshness of the oil. It prevents air from entering the container, minimizing oxidation and extending the shelf life of the oil. This is especially crucial for delicate oils, such as fragrant oils, as they can be easily affected by environmental factors and lose their aromatic qualities.

By storing fragrance oil in a glass container with a tight lid, you can rest assured that the oil will maintain it’s original scent and overall quality. It’s a simple and effective way to ensure that your fragrance oils stay fresh and ready for use.
