When formulating skincare with essential oils, selecting the right packaging is crucial both for preserving the integrity of the formulas as well as for user safety. The active compounds in essential oils can react with certain materials, while their volatile nature means containers need to protect against oxidation, evaporation, and leakage.
Glass Bottles
Glass is impermeable and chemically non-reactive, making it an ideal choice for essential oil products. Oils will not degrade or leach chemicals when in contact with glass. Dark colored glass especially protects light-sensitive oils from UV damage. The heavy, rigid material also keeps formulations stable. Glass dropper bottles enable controlled dispensing of serum-type products. For luxury appeal, decorative glass with etchings or ornate shapes can be used.
Aluminum and Tin Containers
Like glass, metals such as aluminum and tin are inert materials that won’t compromise essential oil stability. Their air-tight seal and opaque finish defend against oxidation. Besides bottles and tubes, aluminum jars and tins give an ultra protective home for balms, oils, and butters. Decorative finishes like matte black, rose gold, or hammered metal appeal to high-end beauty consumers.
Plastic Bottles and Tubes
Of the plastic resin options, HDPE and PET provide the best essential oil compatibility, resisting absorption and chemical interactions. However, lower grade plastic may allow the permeation of some volatile compounds over time, reducing potency. Plastic tubes efficiently dispense viscous formulas like creams but can warp and degrade with some oil components.
Airless Pumps
Airless packaging features an internal vacuum to force products out without letting air back in. This prevents oxidation while hygienically dispensing creams or liquids. Products with nutritive carriers like plant oils or butters could be paired with airless pumps for extended freshness.
Lip Balm Tubes
Standard lip balm tubes with a twist mechanism protect solid balms containing essential oils. The screw top keeps the product well sealed. Just check that the plastic and any internal seals or linings are resistant to the oils used.
Roller Ball Bottles
Glass roller balls are ideal for serum-texture oils, enabling easy application while keeping the product contained. Avoid plastic roller balls as they can warp or crack with repeated exposure to essential oils.
Considerations
Avoid plastic packaging lined with foam or silicone, as these may absorb oils. Similarly, oils can degrade adhesive glues in labels or seals. Essential oils should not be stored long term in bags or paper as they can stain and the paper is porous.finally, Always choose packaging compliant with skincare regulations and safety tested for leakage or breakage.
In summary, glass and metal provide ideal stability and safety for essential oil formulations. Seek out quality materials, protective mechanisms like airless pumps, and minimal use of plastic components. With the right packaging, you can harness the power of essential oils in skincare products.
