Which bottles are best for essential oils, serums, and essences?
Why is proper storage of essential oils so important?
Essential oils derived from various plant materials are mixtures of volatile substances, usually light yellow, greenish, or bluish-gray liquids. These essences typically have complex chemical compositions, intense aromas, and contain numerous biologically active compounds.
Proper storage is essential to preserve these properties. Packaging for serums and essences must not be chosen at random. Containers should protect the contents from sunlight and moisture, while also acting as a barrier that helps keep plant extracts fresh and effective over time.
Which bottles to choose for essential oils: glass or plastic?
Choosing the right packaging is key when storing essential oils, serums, and plant-based essences. These highly concentrated products require containers that are fully compatible with their formulas. The oils must not react with the packaging, and likewise, the materials used to make the bottles must not interfere with the volatile compounds.
For essential oils, serums, and botanical extracts, glass packaging is the most reliable option. This includes dropper bottles and roll-on types. Glass provides an airtight barrier, ensuring safety and hygiene. It also adds a premium feel that highlights the product’s high-end character.
Glass cosmetic bottles are ideal for storing serums and essences because they don’t react chemically with the contents and offer excellent protection for biologically active ingredients. Another advantage is sustainability — unlike plastic, glass is recyclable and reusable
Does the color of bottles for storing essential oils and plant essences matter?
Like many other natural cosmetics, essential oils are prone to oxidation. This means exposure to oxygen can alter their scent, color, and even reduce their effectiveness. To maintain quality and extend shelf life, it’s essential to store them in colored glass containers.
Cosmetic manufacturers typically choose dark glass bottles for essential oils because they effectively block UV light. Cobalt blue and amber glass bottles offer the best protection. It's also important to consider airtightness. To limit the amount of air entering the container, smaller bottles — such as 10, 20, or 30 ml — are often the best choice.
