Product description

Dropper white-gold, 84 mm

White-gold dropper is a closure for bottles with an 18/410 neck that dispenses liquid cosmetic preparations drop by drop. The contents do not spill or drip on their own — they are applied precisely where the customer needs them. The white colour with a gold detail suits products where the packaging should look clean while matching a coloured label.

Most commonly used for facial and oil serums, blends of carrier and essential oils, nail and cuticle care, beard oil, or concentrated active ingredients where every drop counts.


What the dropper consists of

  • Glass tube – draws up and dispenses the contents; glass does not react with oils or essential oils and leaves no odour of its own in the contents.
  • Silicone bulb – squeezing it draws the liquid in; when released, the dropper holds the liquid, and gentle squeezing dispenses it drop by drop.
  • 18/410 screw closure – the plastic inner part with the thread seals the bottle; the aluminium sleeve gives the closure its gold appearance.

How to use the dropper

The dropper is screwed onto a bottle with an 18/410 neck in place of a standard cap. To dispense, squeeze the bulb, submerge the tube in the contents, and release to fill it. Gentle squeezing then delivers the contents one drop at a time. For standard oils and water- or alcohol-based solutions this is a reliable way to apply small, repeatable amounts.

The dropper length should correspond to the height of the bottle. A correctly sized tube reaches almost to the bottom, so even the last of the contents can be dispensed. A tube that is too short leaves part of the product in the bottle; one that is too long rests against the bottom and bends the closure.

Once fitted, the dropper occupies part of the internal space of the bottle. For this reason the bottle should be filled only to the nominal volume, not to the rim of the neck. The headspace between the nominal and total volume is reserved for the dropper tube and for expansion of the contents with temperature changes. If the bottle is overfilled, the contents will overflow when the dropper is screwed on.


Suitable contents

  • Carrier and essential oils – the glass tube does not react with them; dosing is precise even with thicker oils.
  • Water-based serums – light serums and tonics with active ingredients, applied a few drops at a time to the face.
  • Alcohol-based preparations and tinctures – drop-by-drop dispensing without spilling.
  • Concentrates and active ingredients – wherever a small, precisely measured amount needs to be added to a formulation.

With more viscous contents (thick oil blends, serums with a higher thickener content) the bulb fills more slowly and the drops are larger. We recommend verifying suitability for a specific formulation by testing: fill the bottle, leave it to stand for several days both upright and on its side, and check for leaks and the condition of the bulb.


Good to know

Before first use it is advisable to wash and disinfect the dropper (with isopropanol or ethanol) and let it dry completely, especially when filling a leave-on product with no strong preservative system. The bulb may deteriorate after prolonged use with strong solvents or a high proportion of essential oils, so inspect it when refilling.

Based on technical documentation, the packaging is suitable for contact with cosmetic products. Bottles with the same 18/410 neck type and ready-made bottle-and-dropper combinations are available in the Handymade range. When combining components yourself, we recommend verifying the seal and dropper performance with the specific formulation.

The dropper consists of several materials (glass, plastic, aluminium, silicone), so the individual parts should be separated for recycling where possible.

The dropper is not intended for airtight sealing of oxygen-sensitive contents. Each time the dropper is used, air enters the bottle, which shortens the period during which oxidation-sensitive oils retain their fresh properties. For such products, choose smaller bottles and use them up more quickly.


Frequently asked questions

Which bottles are compatible with the white-gold dropper 84 mm?
The white-gold dropper fits bottles with an 18/410 neck and a height such that the tube reaches almost to the bottom. The 18/410 thread is standard on small glass bottles for serums and oils. Compare the dropper length from the product specifications with the height of the bottle up to the neck to ensure the last of the contents can be dispensed.
Is the dropper suitable for essential oils?
Yes, the glass tube is resistant to essential oils and does not alter their scent. The silicone bulb does not come into contact with the contents during normal use, but during long-term storage of the bottle on its side or when overfilled it may come into contact with them. For this reason the bottle should be filled only to the nominal volume and stored upright.
Why does the contents overflow after screwing on the dropper?
The contents overflow because the bottle was filled above the nominal volume. Once the tube is submerged it displaces part of the contents, so there must be a gap between the nominal and total volume of the bottle. Fill to the nominal volume stated for the bottle and leave a few millimetres of space below the neck before screwing on the dropper.
Can the dropper be reused?
Yes, the dropper can be reused if cleaned thoroughly. Rinse both the tube and the bulb with warm water and a mild detergent, then with isopropanol or ethanol, and allow to dry completely so that residues of the previous contents do not affect the new product. Before refilling, check that the bulb holds its shape and that the thread still closes securely.
Is the dropper suitable for water-based serums or only for oils?
The dropper is suitable for both water-based and oil-based contents; only the drop size and speed differ. Water-based serums and alcohol solutions drip faster and in smaller drops; thick oils drip more slowly. With water-based leave-on products, ensure adequate preservation, as air enters the bottle with each use and the tube comes into contact with the skin or hands.
