White Glass Bottle, Gold White Dropper, 15 ml

The white glass medicine bottle with a white and gold dropper, 15 ml, is a ready-made set for serums, facial oils and concentrates of active ingredients that are dispensed drop by drop. White glass conceals the contents and limits light exposure, so it also suits blends with essential oils, oil extracts or vitamins, which deteriorate faster in light. The 15 ml volume is right for a travel size, a customer sample or a small batch of your own serum that you use up before it starts to change.

The dropper with a glass tube and a silicone bulb has a white and gold finish that matches the white bottle. The set therefore looks like a uniform pack, ready for sale or gifting. The dropper screws directly onto the 18/410 neck finish, and no other closure is needed.

Suitable uses

• Serums and concentrates – water-based and oil-based serums with a higher content of active ingredients, where precise dispensing of a few drops matters.
• Facial, beard and nail oils – light blends that are applied with the dropper directly onto the skin or into the palm.
• Essential oil blends in a carrier oil – aromatherapy blends and perfume oils, where white glass protects sensitive components from light.
• Samples and test batches – the small volume allows you to try out a recipe or divide a larger batch into several packs.

Thicker creams and balms are not dispensed with a dropper. Jars or bottles with a pump are more suitable for them.

Nominal volume and brimful capacity

The nominal volume of 15 ml is the volume the medicine bottle is intended for in normal filling. The brimful capacity is the physical volume up to the neck, and you will find it in the parameters. The difference between them is a reserve for the glass tube of the dropper, which pushes part of the contents upwards when screwed on, and for the expansion of the contents when the temperature changes. The bottle is therefore filled to the nominal volume, not to the brim. If it is overfilled, the contents will overflow through the thread after the dropper is fitted and remain in it.

Preparation and filling

Before the first filling, the bottle and the dropper are washed, disinfected with isopropyl alcohol or ethanol and left to dry completely. Residual water in the glass tube or in the thread would get into a water-based product, so the dropper is dried with the tube facing down.

Glass is sensitive to sudden changes in temperature. Do not pour a hot oil phase or a freshly melted mixture into a cold medicine bottle. Let the contents cool to at least room temperature. A small funnel or syringe helps with filling, as the narrow neck of the medicine bottle is harder to fill from an ordinary beaker.

Good to know

The bottle and the dropper are declared as suitable for contact with cosmetic products, and the declaration of conformity is available with the product. The set as a whole is intended for cosmetics, not for food.

The silicone bulb and the plastic parts of the dropper come into contact with the contents when drawing up the liquid and when the bottle is tilted. For concentrated essential oils, perfume compositions with a higher proportion of solvents or alcoholic tinctures, we recommend checking beforehand whether the bulb softens or changes shape over time.

The medicine bottle can be reused. After it is emptied, it is washed, disinfected and dried in the same way as before the first filling. For the dropper, it is worth checking that the bulb has not changed and that the tube has not come loose from the head. The 18/410 neck finish also fits other closures with the same type of neck, which you will find in the Handymade range together with ready-made packaging + closure combinations. For your own combination, we recommend checking the tightness and the behaviour of the packaging with your specific formulation.

For recycling, the bottle is sorted as glass. The dropper combines glass, silicone, plastic and aluminium, so it is separated from the bottle before disposal and sorted according to local rules.
