The shelf life of essential oils and cosmetic ingredients depends largely on the type of bottle they are stored in. Green glass filters out UV radiation and a significant portion of visible blue light, while the aluminium cap provides a chemically inert, corrosion-resistant seal. This 88-piece pack of 50 ml bottles is built for small businesses and artisan makers who regularly bottle their preparations with a consistent look.
What is included in this pack of 88
The pack contains 88 50 ml green glass dropper bottles and 88 matching aluminium caps. Each bottle is approximately 100 mm tall, 42 mm in diameter and has a net weight of around 70 g. Gross pack weight is roughly 6.78 kg. The cap features a standard GL18 thread and an internal seal liner.
Green glass and its light-filtering benefit
In addition to the UV range, green-tinted glass also reflects the shortest visible wavelengths — especially blue light. These are the very wavelengths that most quickly trigger oxidation in essential oils and botanical extracts. Preparations stored in green glass retain their original scent profile noticeably longer. Glass is chemically inert and does not release plasticisers or other migratable substances.
Aluminium cap details
The aluminium cap provides a corrosion-resistant, airtight seal that prevents the evaporation of volatile components. It contains no BPA, phthalates or other plastic plasticisers, and does not react with citrus or high-monoterpene essential oils — the same oils that over time soften or discolour plastic caps. Aluminium is also readily recyclable.
Areas of use
- Bottling essential oil blends and aromatherapy compositions
- Storing perfume bases and colognes
- Packaging your own facial serums, skincare oils and body oils
- Filling botanical tinctures and hydrosols into dropper bottles
- Building a small-business label with a consistent visual identity
Cleaning and recycling
Wash the bottle with warm water and a mild dish soap, then rinse with 70% isopropyl alcohol to remove residual scents. Avoid the dishwasher, as high temperatures and strong detergents can fade labels and over time damage the cap's internal seal liner. Once fully dry, the bottle can be refilled or placed in glass recycling.
