Amber Round Sirup Glass Bottle, 28 mm, Rose Gold Aluminium Cap, 50 ml

The amber glass medicine bottle with a volume of 50 ml and a rose gold aluminium cap makes ready-to-use packaging for facial and body oils, oil serums, tinctures and other products that should stay protected from light. Dark glass reduces the amount of daylight reaching the contents, which you will appreciate with vegetable oils and blends with essential oils, where light speeds up yellowing and oxidation.

The set is declared suitable for contact with cosmetics. Glass does not react with common cosmetic raw materials, does not absorb fragrances or dyes, and can be reused. The cap screws onto the 28 mm neck and closes the bottle tightly. The contents are then poured out or decanted directly through the neck.

What the set is suitable for

• Facial and body oils – amber glass protects fatty acids from light and does not affect the composition of the oil.
• Oil serums and blends with essential oils – glass withstands even concentrated essential oils, which could damage plastic over time.
• Tinctures, alcohol extracts and herbal macerated oils – alcohol and water-alcohol mixtures do not harm glass, and the contents stay in the dark.
• Massage oils and oil blends for hair – the smaller volume allows you to mix a fresh batch without long storage.
• Samples and gift packaging – the rose gold cap gives the packaging a finished look without any further finishing.

Filling and volume

The nominal volume is the amount the bottle is intended for under normal filling. The brimful volume is the physical volume up to the neck and you can find it in the parameters. The difference between the two values is a reserve that stays free for the closure or dropper and for the expansion of the contents when the temperature changes. For this reason, fill the bottle up to the nominal volume, not to the brim.

The narrow neck of the medicine bottle is filled using a funnel. With thicker oil blends, it helps to let the contents warm to room temperature before filling so that they flow better.

Cap and seal

The aluminium cap has a sealing liner made of polyethylene foam (EPE) inside, which sits on the rim of the neck and prevents leaking. The metal does not come into direct contact with the contents, as the liner separates them. It is enough to tighten the cap by hand, as excessive force compresses the liner and the seal gets worse. After opening and closing the bottle again, check that the liner stays in place and is not bent.

This set does not provide drop-by-drop dispensing. If you want to measure the contents more precisely, droppers or other closures with the same neck type can be chosen for the bottle. You can find ready-made bottle + closure combinations in the Handymade range. With your own combination, we recommend verifying the tightness, dispensing and behaviour of the packaging with your specific formulation.

Good to know

Before the first filling, wash the bottle, disinfect it with isopropyl alcohol or ethanol and let it dry completely upside down. Residual water in an oil-based product shortens its shelf life and encourages the growth of microorganisms. Simply wipe the cap and its foam liner with alcohol, as longer soaking is not good for the liner.

The glass bottle on its own has a certificate for direct contact with food. The cap does not have such a declaration, so the set as a whole is intended for cosmetics.

Amber glass reduces light but does not block it completely. Store light-sensitive products away from direct sunlight and heat sources anyway. After thorough washing and disinfection, the bottle can be reused. Before disposal, separate the glass from the aluminium cap, as each material belongs in a different sorted waste collection.
