Green Glass Bottle, Gold Black Dropper, 50 ml

The green glass medicine bottle, 50 ml, with a black and gold dropper is used for filling and dispensing liquid cosmetic preparations drop by drop. Green glass reduces light exposure, so it is particularly suitable for facial serums, blends of vegetable and essential oils, beard and hair oils, tinctures or alcohol extracts, which lose stability when exposed to light for longer periods. The dropper dispenses precisely and the contents come into contact with fingers and air less during use than with a wide neck.

The set is declared suitable for contact with cosmetic products.

How the set works

• Medicine bottle – stable, with a narrow neck, made of glass that does not react with oils, alcohol or most common cosmetic ingredients.
• Dropper – metal collar in black and gold, silicone bulb and glass tube. The length of the tube is matched to the height of the bottle, so it draws up the contents from the bottom as well.
• Thread – the same on the bottle and the dropper, so the closure screws on directly and the set holds together even when carried.

What it is suitable for

The bottle is most often filled with preparations that are applied in small amounts and where the dose matters. These include facial oil serums, cuticle oils, hair oils for the ends, blends of essential oils with a carrier oil, or herbal tinctures. It is also suitable for water-based and hydrosol serums with soluble active ingredients, provided they are properly preserved.

It is not suitable for thick creams, butters and balms. The dropper does not draw up viscous contents and the narrow neck makes cleaning difficult.

Nominal volume and brimful capacity

Nominal volume is the amount the bottle is intended for in normal filling. Total brimful capacity is the physical volume up to the neck and you can find it in the parameters. The difference between them leaves room for the dropper tube, which displaces part of the volume once screwed in, and for the expansion of the contents when the temperature changes. For this reason, fill the bottle to the nominal volume. If you fill the bottle to the brim, the contents will overflow through the neck when the dropper is inserted.

Good to know

The silicone bulb and the plastic parts of the dropper come into contact with the contents only briefly while drawing up. With concentrated essential oils, pure alcohol or solvents, first check how the dropper behaves with your specific formulation, for example whether the bulb softens over time or the tube stops sealing. The glass itself withstands these substances without problems.

Glass does not tolerate sudden temperature changes well. Let hot contents cool down before filling and do not put the bottle straight from the cold into warm water.

The set can be reused. After emptying, wash the bottle with warm water and washing-up liquid, rinse the dropper tube with alcohol and leave everything to dry. When changing the contents, for example from oil to a water-based serum, thorough degreasing is necessary.

Closures with the same neck type as stated in the parameters, as well as other ready-made combinations, can be found in the Handymade range. If you make your own combination, we recommend checking the tightness, the dispensing and the behaviour of the packaging with your specific formulation.

Once the dropper is separated, the bottle belongs in glass waste. The dropper consists of metal, silicone, plastic and glass, so sort it according to its predominant material or dispose of it as mixed waste.
