The quality of essential oils, tinctures, and botanical extracts depends not only on the raw materials but also on the storage container. Light — particularly UV and shorter visible wavelengths — rapidly degrades volatile aromatic compounds. This pack of 110 contains 30 ml black glass dropper bottles, with a black plastic screw cap. It is intended for small-scale makers, essential oil blenders, and natural cosmetics formulators who want maximum light protection for their preparations.
What the pack of 110 contains
The pack contains 110 30 ml black glass dropper bottles of uniform size and finish. Each bottle is approximately 85 mm tall, 35 mm in diameter, with an empty weight in the range of 59–63 g per bottle. The total gross weight of the pack is approximately 6.655 kg. The bottle neck uses the GL18 standard, so commercially available caps, droppers, and pumps will fit.
Black glass and complete light-blocking
Black glass provides significantly stronger light protection than amber: it is virtually opaque, blocking the full spectrum of visible light as well as UV radiation. This is particularly important for sensitive, photocatalytically degraded components — such as citrus essential oils, retinol-based serums, or certain herbal tinctures. A light-free environment substantially extends the shelf life of the preparation and preserves the original scent profile. The glass is chemically inert, contains no plasticisers, and does not react with the stored substances — making it the recommended primary packaging for essential oils and natural cosmetics.
Details of the black plastic screw cap
The black plastic screw cap features an inner sealing liner for leak-proof, odour-tight closure. Its matt black colour matches the black glass of the bottle, giving a uniform, professional appearance to the finished product. The cap is easy to screw on and reusable. It is suitable for both storage and everyday dispensing, especially for cosmetics that are poured into the palm rather than dripped.
Areas of use
- Bottling and gifting your own essential oil blends
- Storing perfume bases and colognes with light protection
- Filling light-sensitive facial serums and retinol-based preparations
- Bottling botanical tinctures, hydrosols, and flower essences
- Building a DIY private-label cosmetics line
Cleaning and recycling
The bottles are easy to clean with warm water and a neutral soap. For stronger fragrance residue, a 70% isopropyl alcohol rinse followed by complete drying is recommended. Avoid dishwasher use, as high temperatures and aggressive detergents can damage labels and cap seals over time. The glass is recyclable; aluminium caps should be sorted into the appropriate metal recycling stream.
