Product description

A black glass bottle with an aluminium cap is a ready-made set for serums, facial and hair oils, oil blends with essential oils, tinctures and tonics. The medicine-bottle-shaped flask with a glossy black surface and the black aluminium cap with an 18/410 thread are a perfect match, so you do not need to search for compatible parts or test whether the combination will seal. The nominal volume of 100 ml corresponds to standard cosmetic packaging dispensed by drops onto the palm or by pouring.

The black opaque glass protects the contents from light, which is especially valuable for products sensitive to oxidation. The glossy dark surface has a uniform appearance and works well with a white, gold or metallic label. The set is declared as suitable for contact with cosmetics. The bottle itself also holds a food-contact certificate, but the aluminium cap does not, so the set as a whole is intended for cosmetic and technical use.

Why choose this set

Light protection – opaque black glass slows the oxidation of vegetable oils, vitamins and essential oils in the finished product.
Chemically stable material – glass does not react with essential oils, alcohol or solvents, which cannot always be said of plastic packaging.
Aluminium cap with sealing insert – the inner EPE foam insert seats on the neck and seals the contents against leakage during normal handling and transport.
Ready-made combination – the cap thread matches the bottle neck, so you do not need to verify closure compatibility.
Reusable – both the glass bottle and the aluminium cap can be refilled after washing and disinfection.

What the set is suitable for

The 100 ml volume suits a facial or body oil, hair oil, massage blend or oil serum. Opaque glass makes sense wherever the contents are rich in unsaturated fatty acids or contain light-sensitive components, such as rosehip, borage or linseed oil, vitamin C in the oil phase, carotenoids or citrus essential oils.

Thanks to the resistance of glass to alcohol, the set is also suitable for tinctures, herbal alcohol extracts and alcohol-containing tonics. It can also be used for liquid water-based products, though bear in mind that without a dropper or pump you will dispense by pouring.

Less suitable for thick creams and butters, which are difficult to dispense through a narrow neck. Wide-neck jars are a better choice for those textures.

Nominal and total volume

For every container we distinguish between nominal volume and total brim-full volume. The nominal volume is the quantity for which the bottle is intended under normal filling. The total brim-full volume is the physical capacity up to the neck and is slightly larger. The difference provides a reserve for the cap with its sealing insert and space for the contents to expand with temperature changes. The bottle is therefore filled to the nominal volume, not to the brim. Filling right up to the neck causes the contents to reach the thread, the cap seals poorly and the packaging becomes stuck.

Oil blends and alcohol extracts expand in volume when warm. If you fill the bottle in a cold room and store it at room temperature, leave sufficient headspace below the neck, otherwise the contents may be forced into the thread when closing.

What to know when filling

Before first use, wash and disinfect the bottle, even if it looks clean. Rinse it with hot water, disinfect with alcohol and leave it to dry thoroughly with the neck facing down. Fill only after it is completely dry; residual water in an oil product would appear as cloudiness and pose a risk to microbiological stability.

Tighten the aluminium cap with moderate force. The sealing insert seats on the neck with just a light tightening; excessive force can damage the thread or deform the insert. For solvent-based products and higher concentrations of essential oils, we recommend verifying the behaviour of the EPE insert by test-filling and monitoring over several weeks.

Glass does not tolerate sudden temperature changes. Allow a hot oil phase or freshly melted product to cool to approximately room temperature before filling. Black glass does not allow you to see the fill level, so when measuring use scales or a measuring cylinder and mark the bottle with the filling date.

If you want to use the bottle with a dropper or pump instead of the cap, choose a closure with the same 18/410 neck type. Ready-made combinations of the bottle with other closures are available in the Handymade range; for a custom combination, verify sealing and dispensing with the specific formulation.

Glass and aluminium are recyclable materials. When disposing, unscrew the cap and place both materials in the appropriate collection.

Frequently asked questions

Does the black glass bottle protect the contents from light?

Yes, black glass is opaque and protects the contents from light. It is therefore suitable for oils with a high proportion of unsaturated fatty acids, essential oils and serums with vitamins that quickly lose efficacy and change scent in light. The drawback is that you cannot see the fill level, so use scales or a measuring cylinder when filling.

Is the set with the aluminium cap suitable for food use?

No, the set as a whole is not declared for contact with food. The glass bottle alone holds a food-contact certificate, but the aluminium cap with the EPE insert does not. The set is therefore intended for cosmetic and technical use. If you need packaging for home oils or syrups, choose the bottle separately and combine it with a closure that carries a food-grade certificate.

Can a tincture or alcohol extract be filled into the black glass bottle?

Yes, glass is resistant to alcohol and tinctures or alcohol tonics are a suitable content for this bottle. Only the cap sealing insert needs to be verified. For high concentrations of alcohol or solvents, we recommend a test fill and checking the seal after several weeks of storage.

How much liquid actually fits in the 100 ml bottle?

The bottle is filled to the nominal volume of 100 ml, even though its physical brim-full volume is slightly larger. The difference is the reserve for the cap with its sealing insert and for the expansion of the contents with temperature changes. Filling right to the brim causes the contents to reach the thread and the cap stops sealing properly.

Can the black glass bottle with the aluminium cap be reused?

Yes, both the glass bottle and the aluminium cap can be reused after thorough cleaning. Wash the bottle with warm soapy water, rinse, disinfect with alcohol and leave it to dry completely. Clean the cap in the same way and check that the sealing insert is not deformed or saturated with the previous contents. If the previous product left a strong scent, it is better to replace the cap.

How do you dispense oil or serum from a bottle without a dropper?

With a screw cap, the contents are dispensed by pouring through the neck, that is by tilting the bottle over the palm or a measuring vessel. For oils this works reliably; for thinner water-based tonics, we recommend careful tilting or replacing the cap with a dropper or pump with the same neck fitting. For precise dispensing in cosmetic production, it is worth working with scales.
