White Glass Bottle, Matte Silver Dropper, 100 ml

Glass bottle with a dropper for serums, oil blends and tinctures, from which the contents are dispensed drop by drop. The white glass hides the contents and limits light exposure, which you will appreciate with vegetable oils, essential oil blends and light-sensitive active ingredients. The set consists of a pharmaceutical bottle with a nominal volume of 100 ml and a dropper with a white cap and a matte silver shell. The length of the dropper is matched to the bottle, so the tube reaches deep enough even when the contents are low.

Both the bottle and the dropper are declared suitable for contact with cosmetic products; you will find the declaration of conformity with the product. For home production and small batches, the 100 ml volume is a medium-sized pack: larger than a typical face serum bottle, but still comfortable to dispense with one hand.

What it is suitable for

• Oil serums and massage oils – the dropper measures the exact amount onto the palm or directly onto the skin; glass does not absorb the odour or colour of the oil.
• Hair and beard oils – thin oil blends are drawn up easily and dispensed drop by drop onto the ends or into the palm.
• Tinctures and alcoholic extracts – glass is resistant to alcohol, and the white wall protects the extract from light.
• Essential oil blends for diffusers or formulations – dispensing by drops is more accurate with concentrated fragrances than pouring from the neck.
• Water-based serums and toners with active ingredients – sensitive ingredients stay in the dark and are dispensed accurately.

How the set dispenses and seals

The dropper has a glass tube, a silicone squeeze bulb and a cap with a matte aluminium shell. When you squeeze the bulb and release it, the tube fills, and the contents are then dispensed drop by drop. Both parts have the same thread type, so the dropper tightens onto the neck and the bottle stays tightly sealed under normal handling.

The tube draws up thin and medium-viscosity liquids without any problem. Thick oils, gels and emulsions are drawn up slowly and drops form with difficulty. A pump or a jar is more suitable for such contents.

Nominal and total volume

The nominal volume is the amount the pharmaceutical bottle is designed for in normal filling. The total brimful volume is the physical volume of the glass up to the neck, and you will find it in the parameters. The difference between them 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.

Good to know

Before the first filling, wash the bottle and the dropper, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Traces of water in an oil serum shorten its shelf life and promote the growth of microorganisms.

The set can be used repeatedly. Before each refill, check that the dropper bulb has not lost its elasticity and that the tube is not cracked. For contents that are in long-term contact with the silicone bulb, for example concentrated essential oils, we recommend verifying the behaviour of the dropper over time with your specific formulation.

If the dropper does not suit your product, you will find other closures with the same neck type in the Handymade range, as well as ready-made combinations of packaging plus closure. For your own combination, we recommend verifying the seal and the dispensing with your specific contents.

The bottle is made of glass and can be recycled. The dropper consists of several materials, so separate it from the bottle before recycling.
