The quality of essential oils, botanical tinctures, and natural cosmetic serums depends not only on the raw materials but also on the storage container. This pack of 110 30 ml frosted green, light-diffusing glass dropper bottles ships with aluminium caps. The UV and blue-light filtering of green glass combined with the light-diffusing matte surface is particularly well suited to an eco-look, natural brand identity: organic cosmetics, phytocosmetics, herbal tinctures, and vintage apothecary-style serums.
What is in this pack of 110
The pack contains 110 frosted green 30 ml glass bottles with aluminium caps. Each bottle has an approximate height of 85 mm, a diameter of 35 mm, and an empty weight of about 50.0 g per piece. The total gross pack weight is approximately 6.05 kg. The bottles have a standard GL18 neck thread, so most caps and droppers common in the essential oil industry fit without issue. Country of origin: China.
Frosted green glass and UV protection
Green glass effectively filters the UV range and the short, blue wavelengths of visible light — exactly the photocatalysts that initiate oxidation in sensitive essential oils. The frosted, light-diffusing surface further reduces the amount of direct light reaching the inside of the bottle. This two-layer protection preserves the scent profile and active ingredient content of the contents longer than clear green or clear glass would. The glass is chemically inert, does not react with essential oils, and contains no plasticisers.
Cap and dropper details
The aluminium cap is a solid metal closure with an inner rubber liner: it is chemically inert, corrosion-resistant, and provides a leak-proof seal. It contains no BPA, phthalates, or other plasticisers, making it safe for long-term storage of essential oils and cosmetic serums. Strong citrus and monoterpene-rich oils do not dissolve or soften aluminium, unlike many plastic caps.
Typical areas of use
- Bottling organic and phytocosmetic serums and facial oils into a uniform, eco-look range
- Dispensing custom essential oil blends and aromatherapy formulations drop by drop

- Packaging vintage apothecary-style, artisan-branded preparations
- DIY cosmetic development and launching own-brand retail products as a small business owner
Cleaning and recycling
Before filling new bottles it is good practice to rinse them with warm water and mild soap, then leave to dry. For bottles that previously contained scented preparations, residual aroma is best removed with isopropyl or ethyl alcohol — particularly important if you plan to fill with a different essential oil. Avoid the dishwasher because of the matte surface, so the labelling and the matte character are preserved over the long term. The glass is recyclable, and the metal cap and glass can be collected separately for recycling.
