White Glass Bottle, Silver Aluminium Cap, 15 ml

The white glass medicine bottle with a 15 ml volume and an aluminium screw cap is a ready-made set for small quantities of cosmetics: facial serums, face and body oils, essential oil blends, tinctures or samples of your own products. The opaque white glass limits the amount of light reaching the contents, which is useful for vegetable oils and light-sensitive active ingredients. Glass does not react with oils or alcohol, so the bottle can also be filled with a concentrated fragrance or an alcohol-based extract.

The set is declared suitable for contact with cosmetics. It is not intended for food.

What it is suitable for

• Serums and facial oils – the 15 ml volume corresponds to a common pack size of a facial oil or serum that lasts several weeks.
• Essential oil blends – glass and aluminium are well compatible with essential oils, and white glass protects the fragrance from light.
• Tinctures and alcohol extracts – glass does not react with alcohol and releases nothing into it, and a tightly closed cap with a liner limits evaporation.
• Samples and travel packs – the small volume and low weight of the set make it suitable for testing formulations, gift sets or a travel version of a product.

Closure and dispensing

The silver aluminium cap with an 18/410 neck finish screws onto the neck of the medicine bottle. Inside it has a foam polyethylene (EPE) liner, which sits against the rim of the neck when tightened and seals the contents. The contents are dispensed by pouring or by taking out the required amount, as the cap itself has no dispensing element. For oils or serums that you want to dispense in drops, choose a different closure with the same neck type.

Closures with an 18/410 neck finish and ready-made combinations of packaging and closure can be found in the Handymade range. If you are creating your own combination, we recommend checking in advance the tightness, the ease of dispensing and how the packaging behaves with your specific formulation.

Filling and volume

The nominal volume of 15 ml is the amount the bottle is designed for in normal filling. The brimful capacity given in the parameters is the physical volume up to the top of the neck. The difference between them is a reserve for the closure and for the expansion of the contents when the temperature changes. Fill up to the nominal volume and leave the space below the neck free. If you fill to the brim, the contents will be pushed out when the cap is tightened and the liner may not seat properly.

The neck of the medicine bottle is narrow, so thick creams and butters are difficult to fill into it. Fill liquid and slightly viscous products using a small funnel or a syringe so that the neck and thread stay clean.

Good to know

Before the first filling, wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in an oil-based product or in an anhydrous serum increases the risk of microbial growth.

Glass does not tolerate sudden temperature changes well. Do not pour a hot phase directly into a cold bottle. Let it cool at least to a temperature at which the container can be held in the hand.

The set can be used repeatedly. Once it is empty, simply wash it, disinfect it and leave it to dry. Before the next filling, check whether the cap liner is damaged or has absorbed the fragrance of the previous contents. At the end of its life, the glass bottle goes in glass recycling and the aluminium cap in metal recycling.
