Gloss Black Glass Bottle, Matte Silver White Dropper, 50 ml

A glass bottle with a dropper for facial serums, oil blends and concentrated active ingredients that are dispensed drop by drop. Black opaque glass blocks light from reaching the contents, so it suits formulations sensitive to oxidation, for example oils with a high proportion of unsaturated fatty acids or serums with vitamins. The 50 ml volume matches a common serum or oil elixir pack size.

The set is supplied as a matched pair: a medicine bottle with an 18/410 neck finish and a dropper whose length is adapted to the height of the bottle, so the tube reaches almost to the bottom and the last of the contents can be used. The dropper consists of a glass tube, a squeeze bulb and a matte silver collar with a thread, which matches the glossy black glass. The bottle and the dropper are declared suitable for contact with cosmetic products; the declaration of conformity and certificates are available with the product.

What it is for

• Facial serums and oil blends – the dropper measures out an exact number of drops, which is an advantage for concentrated products with a high proportion of active ingredients.
• Face, beard and hair oils – dark glass slows the yellowing and oxidation of vegetable oils.
• Macerated oils and tinctures for cosmetic use – glass does not react with alcohol or oils, and the dropper dispenses a small amount into the finished product or directly onto the skin.
• Samples and test batches – 50 ml is enough to try out a recipe before making a larger quantity, and the contents stay protected just as in a larger pack.

Filling and dispensing

The nominal volume of 50 ml is the amount the bottle is intended for in normal filling. The brimful capacity is the physical volume up to the neck and is slightly larger. The difference is a reserve for the dropper tube, which pushes part of the contents upwards once screwed in, and for the expansion of the contents when the temperature changes. Therefore, fill only up to the nominal volume, not to the brim. An overfilled bottle will overflow when the dropper is fitted.

A funnel with a narrow neck or a syringe works well for filling. The liquid level cannot be seen through black glass, so fill a measured amount rather than going by eye. Tighten the dropper by hand, not by force. The aluminium collar may deform if overtightened and stop sealing.

Good to know

The dropper is made of several materials: glass, aluminium, polypropylene and silicone. With pure essential oils or blends with a high proportion of them, we recommend checking how the squeeze bulb and the seal behave after prolonged contact with the contents. This type of dropper is used as standard with common facial serums and vegetable oils.

Glass withstands normal temperatures during filling, but not thermal shock. Let hot contents cool to at least room temperature before filling, as cold glass may crack if suddenly heated. After thorough washing and disinfection, the bottle is suitable for refilling. Replace the dropper if the bulb has lost its elasticity or the tube no longer reaches the bottom.

Closures with the same neck type and other ready-made packaging + closure combinations can be found in the Handymade range. If you make your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation. At the end of its life, the medicine bottle goes into glass recycling; take the dropper apart and sort the individual parts by material.
