Amber Glass Bottle, Slim, Black Aluminium Cap, 50 ml

This amber glass medicine bottle with a volume of 50 ml and a black aluminium cap is intended for filling face and massage oils, oil serums, tinctures and alcohol extracts. Amber glass filters out the light that speeds up the oxidation of vegetable oils and the breakdown of sensitive active ingredients, so the contents stay in their original condition for longer, even on a shelf. The set comes with a screw cap for an 18/410 neck finish, so you only need to fill the packaging and close it.

The tall, slim shape of the medicine bottle with a narrow neck makes it easier to pour small amounts and limits contact between the contents and air when the bottle is opened. Glass does not react with alcohol or essential oils and does not absorb scents, so the bottle can also be filled with concentrated blends that would gradually damage plastic packaging.

What it is good for

• Face and body oils – blends of vegetable oils prone to yellowing (rosehip, cranberry, evening primrose) need protection from light.
• Oil serums with active ingredients – lipophilic vitamins, coenzyme Q10 or bakuchiol break down more slowly in amber glass than in clear glass.
• Tinctures and alcohol extracts – alcohol does not damage the glass, and the cap with a liner limits evaporation.
• Essential oil blends and massage oils – the 50 ml volume suits home use as well as selling smaller packs.
• Samples and trial batches – when testing a formulation, it is worth filling the same packaging in which the product will be sold later.

Cap and dispensing

The black aluminium cap has an inner liner made of EPE, a foamed polyethylene, which sits on the rim of the neck once tightened and seals the contents. The product is dispensed by unscrewing the cap and pouring, so the set suits products from which a larger amount is taken at once: massage oil into the palm, an extract for the bath, oil for a production blend. A black cap on amber glass looks neutral and lets the label stand out.

If you need to measure the contents out drop by drop, the Handymade range includes the same medicine bottle combined with a dropper for the same neck type. If you make your own combination, we recommend checking the tightness and behaviour of the closure with your specific formulation beforehand.

Volume and filling

The nominal volume of 50 ml is the amount the medicine bottle is designed for in normal filling. The brimful capacity, that is the physical volume up to the top of the neck, is slightly larger and can be found in the parameters. The difference leaves room for the cap and for the expansion of the contents when the temperature changes, so fill only up to the nominal volume. With oils and alcohol-based blends, this headspace also reduces the risk of the contents overflowing across the thread when the cap is screwed on.

Good to know

• Preparation before first filling – wash the medicine bottle and the cap, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Residual water in an oil-based product encourages the growth of microorganisms.
• Reuse – the glass withstands repeated washing and disinfection. Check the cap liner after use; if it has absorbed the scent of the previous contents or has been compressed, replace the cap.
• Glass and heat – do not pour hot blends into the medicine bottle and do not expose it to sudden temperature changes, for example moving it from the fridge into hot water.
• Contact with cosmetics – the set is declared suitable for use with cosmetic products, and the declarations of conformity for both components are provided with the product.
• Contact with food – only the glass medicine bottle on its own has a certificate for direct contact with food. The aluminium cap does not have one, so the set as a whole is intended for cosmetics.
• Recycling – take the empty medicine bottle to glass collection; the cap belongs with metals. Separate them before disposal.
