Green Glass Bottle, Gold Black Dropper, 30 ml

A green glass bottle with a nominal volume of 30 ml and a black and gold dropper is used for filling facial serums, oil blends and tinctures that are dispensed drop by drop. The tinted glass reduces the light reaching the contents, which you will appreciate with formulations containing vegetable oils, vitamins or extracts that lose their effectiveness faster in light. The set is supplied as a ready-made pair of bottle and closure. Before filling, simply wash and dry it.

The bottle has the shape of a medicine bottle with a narrow neck, a stable base and straight walls. The length of the dropper is matched to the height of the bottle, so it reaches deep to the bottom and the contents can be used up without tilting. The black and gold finish looks understated on a shelf of cosmetics and matches darker packaging colours.

What it is suitable for

• Facial and hair serums – concentrated products where customers need to measure out two to five drops, not a whole palmful.
• Oil blends for the face and cuticles – glass is resistant to oils, and the dropper allows precise application to a small area.
• Tinctures and alcohol extracts – alcohol does not damage glass, and tinted glass also slows the fading of plant pigments.
• Samples and trial batches – a volume of 30 ml is enough to test a formulation or for a gift pack without a large amount of raw material.

How the set works

The dropper is screwed onto the neck of the bottle, and its collar also serves as the cap. Squeezing the bulb draws the contents into the glass part, and releasing it dispenses them drop by drop. With thicker oils the drops form more slowly, with alcohol tinctures faster. You should therefore test the dispensing with your specific formulation before you include it in the instructions for customers.

The dropper is made of several materials: glass, silicone, aluminium and PP plastic. It is mainly the glass part that comes into contact with the contents. The bulb and the seal touch the contents only when the bottle is lying down or inverted, so store and transport it upright.

Volume and filling

Nominal volume is the amount the bottle is intended for with normal filling. 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 part of the dropper, which raises the liquid level once screwed in, and for the expansion of the contents when the temperature changes.

Good to know

• Preparation before the first filling – wash the bottle and the dropper, disinfect them with isopropyl alcohol or ethanol and let them dry completely, so that no water gets into an oil-based product.
• Reuse – glass withstands repeated washing and disinfection without limit. With the dropper, check after each wash that the bulb keeps its shape and the glass part is not cracked.
• Glass and heat – do not fill the bottle with hot contents and do not expose it to sudden changes in temperature. Let the finished serum or oil blend cool to room temperature before filling.
• Other closures – the bottle fits closures with the same type of neck as stated in the parameters, and you will find ready-made combinations in the Handymade range. If you make your own combination, we recommend checking the tightness and dispensing with your specific formulation.
• Contact with cosmetics – based on the technical documentation, the bottle and the dropper are suitable for use with cosmetic products. The set is not intended for filling food.
• Recycling – after use, take the glass bottle to glass collection. The dropper is made of several materials, so separate it from the bottle before disposal.
