Gloss Black Glass Bottle, Gold Black Dropper, 30 ml

The glossy black glass bottle with a black and gold dropper is a complete set for dispensing liquid cosmetics drop by drop. The opaque black glass does not let light reach the contents, so the 30 ml size is especially suited to facial serums, oil concentrates with active ingredients and blends of essential oils in a carrier oil, whose components lose potency or change colour when exposed to light. The dropper with an 18/410 neck finish fits directly onto the bottle neck. The packaging is supplied assembled, so you do not need to look for a separate closure.

The set is declared as suitable for contact with cosmetic products. Only the glass bottle on its own has a certificate for direct food contact; the dropper does not have one, so the set as a whole is intended for cosmetics.

What it is suited for

• Facial and eye serums – both water-based and oil-based, where a few drops are dispensed per use.
• Oil blends with active ingredients – oils with vitamin E, coenzyme Q10 or retinol derivatives, which are sensitive to oxidation and light.
• Blends of essential oils in a carrier oil – massage and aromatherapy blends where you measure by drops.
• Beard and hair oils – dispensing drop by drop straight into the palm or onto the hair ends.
• Samples and small batches – when testing a recipe, 30 ml is enough to check how the formulation behaves without wasting raw materials.

How to work with the set

The dropper consists of a glass tube, a silicone bulb and a threaded PP part covered by a gold aluminium overcap. Squeezing the bulb draws in the contents and releasing it dispenses them drop by drop. The length of the dropper is matched to this bottle, so the tube reaches deep enough even when the level is low. The gold overcap and the black glass give the finished product a uniform look without any further decoration.

The nominal volume of the bottle is the amount the packaging is designed for under normal filling. The brimful capacity is the physical volume up to the neck and is slightly larger. The difference between the two is a reserve for the dropper tube, which is immersed in the contents once the dropper is screwed on, and for the expansion of the liquid when the temperature changes.

Good to know

• Preparation before the first filling – wash the bottle and the dropper, disinfect them and let them dry completely. Residual water in an oil serum shortens the stability of the product.
• The fill level is not visible – the black glass is opaque. Mark the filling date and keep in mind when selling that the customer cannot see how much of the product is left.
• Glass and heat – let the contents cool to room temperature before filling, as a sudden temperature difference can damage the glass.
• Water-based and oil-based contents – the glass and the glass tube withstand common cosmetic contents. Water-based serums need preservation, because the dropper comes into contact with the skin and with air at every use.
• Reuse – after thorough washing and disinfection, the bottle can be used again. For the dropper, check that the silicone bulb has not hardened and that the tube is not chipped.
• Recycling – the bottle belongs in glass waste. The dropper combines PP, aluminium, glass and silicone, so separate it from the bottle when sorting.

You will find closures with the same 18/410 neck finish and other ready-made bottle and closure combinations in the Handymade range.
