Product description

A black glass bottle with a capacity of 15 ml is designed for contents that need to remain protected from light. The opaque black glass blocks light entirely, making it particularly suitable for products that lose their efficacy or change colour and scent when exposed to light. The small volume makes it ideal for concentrates that are dispensed drop by drop or in small amounts.

It is suitable for facial serums, oil serums and elixirs with active ingredients, essential oil blends, tinctures and alcohol-based extracts, perfume oils and concentrates, as well as samples or travel sizes of thinner cream products. Glass is chemically resistant and does not react with the contents, making it equally suitable for water-based, alcohol-based and oil-based formulations. The packaging is suitable for direct contact with food and with cosmetic products, so it can also be used for homemade herbal oils, syrups or aromatic essences in the kitchen.

Key benefits

Light protection – opaque black glass helps maintain the stability of essential oils, vitamins, plant extracts and unsaturated oils, which oxidise quickly when exposed to light.
Chemical resistance – glass does not absorb fragrance or colourants and does not react with alcohol, acidic solutions or concentrated essential oils, which can degrade certain plastics.
Small volume for concentrates – 15 ml corresponds to a standard serum or essential oil blend size, meaning the contents are used up before they have time to degrade.
Glossy black surface – creates a uniform, elegant appearance, conceals the contents and any sediment, and provides an excellent contrast for light or gold labels.
Food-grade and cosmetic-grade quality – suitability for contact with food and cosmetics is supported by the packaging's technical documentation, so the bottle handles both cosmetic and culinary applications.

Nominal and total volume

Two figures are distinguished for packaging. The nominal volume is the quantity the bottle is intended for under standard filling conditions, and this is the figure stated on the finished product label. The total volume to the brim is the physical capacity up to the neck. The difference between the two provides headspace for the closure, the glass tube of a dropper or the tube of a pump, and for expansion of the contents with changes in temperature. The bottle should therefore be filled to the nominal volume, not to the brim. Specific values can be found in the product parameters.

When filling with a dropper, bear in mind that the glass tube displaces some of the contents upward when inserted. If the bottle is filled right up to the neck, the contents will overflow when closing and contaminate the thread, causing a poorer seal.

Closures and combinations

The bottle has an 18/410 thread, the most common neck type for small glass packaging. Closures with the same neck type and ready-made bottle-and-closure combinations are available in the Handymade range. When assembling your own combination, we recommend verifying the seal, dispensing performance and behaviour of the packaging with your specific formulation. This applies especially to alcohol-based contents, which wick easily through threads, and to thicker oils, which flow slowly through a dropper.

What is good to know

Preparation before first use. Before use, wash the new packaging with warm water and a mild detergent, rinse thoroughly, disinfect with isopropyl alcohol or 70% ethanol and leave to dry completely with the neck facing down. Residual water would dilute anhydrous products and create conditions for microbial growth.

Labelling. The flat section of the body on a 15 ml bottle is relatively narrow, so plan for a slim label. White, metallic or transparent labels with light printing show up best on glossy black glass. Label dimensions suitable for this bottle can be found in the parameters.

Glass and temperature. Glass does not tolerate thermal shock. Do not fill hot contents into a cold bottle, and do not move a filled bottle directly from cold to warm surroundings. Dark glass also heats up quickly in direct sunlight, which is detrimental to the contents despite the light protection.

Recycling. Glass belongs in the glass recycling stream; unscrew the closure before disposal and sort it separately according to its material.

When producing smaller batches, fill the bottles just before sealing and close them immediately after filling. The shorter the contents remain open, the less air and moisture enters, which is just as important for active ingredients sensitive to oxidation as protection from light.

Frequently asked questions

Does a black glass bottle protect contents from light better than brown glass?

Yes, black glass is opaque, whereas brown glass only significantly reduces light transmission. For everyday essential oils and serums, brown glass is sufficient; for particularly sensitive ingredients such as retinoids, vitamin C in oil form or certain plant extracts, black glass provides greater assurance. The downside is that you cannot see the contents or how much remains.

How much can a 15 ml glass bottle actually hold?

The bottle is designed for 15 ml of contents, although its physical volume to the brim is larger. The difference serves as headspace for the closure or dropper and for expansion of the contents with temperature changes. If the bottle is filled to the brim, the contents will overflow when the dropper is inserted and contaminate the thread. A correctly filled bottle has a visible gap below the neck.

Is the 15 ml glass bottle suitable for essential oils and alcohol-based tinctures?

Yes, glass is one of the most suitable materials for essential oils and alcohol-based contents. It does not react with them, does not absorb fragrance, and concentrated essential oils will not damage it the way they can damage certain plastics. With alcohol-based contents, pay attention to the closure, as alcohol wicks easily through threads and evaporates through a poorly sealing cap.

Can the black glass bottle be washed and reused?

Yes, glass can be refilled after washing and disinfection without any loss of properties. Wash the bottle with warm water and detergent, remove oil residues with ethanol or isopropyl alcohol, then leave it to dry completely with the neck facing down. Dropper inserts or caps made from plastic and rubber will absorb fragrance and colourants, however, so it is better to replace them when changing the contents.

What closure fits a glass bottle with an 18/410 thread?

All closures with the same 18/410 neck type fit the bottle — droppers, caps with sealing inserts, spray pumps and small dispensing pumps. The choice depends on the contents: droppers are used for serums and oils, spray pumps for water-based and alcohol-based contents, and caps for storing blends. Ready-made bottle-and-closure combinations are available in the Handymade range.

Is the 15 ml glass bottle also suitable for food?

Yes, the packaging is suitable for direct contact with food and with cosmetic products. It is therefore well suited for homemade herbal or spiced oils, concentrated syrups, aromatic essences or flavouring extracts. For food use, the same principle applies as for cosmetics: wash, disinfect and allow to dry completely before first use.
