Blue Glass Bottle, Gold White Dropper, 30 ml

A 30 ml glass bottle with a dropper is a set designed for dispensing serums, facial oils, tinctures and essential oil blends, that is, products that are applied drop by drop and need protection from light. Blue glass reduces the amount of light reaching the contents, which slows down changes in oils, antioxidants and aroma compounds. The small volume suits recipes where only a few drops are used per application.

The bottle is a medicine bottle with a narrow neck and comes with a white and gold dropper that screws directly onto the thread. The set is supplied as a ready-made pair, so there is no need to look for a closure with the same neck. Both the bottle and the dropper are declared suitable for contact with cosmetic products. The set is not intended for foodstuffs.

What it is suitable for

• Facial and hair serums – water-based and oil-based serums with active ingredients, dispensed in a few drops per use.
• Facial and body oils – blends of vegetable oils, where blue glass limits the effect of light on oxidation.
• Essential oil blends and fragrance compositions – the dropper allows you to count drops precisely when diluting or preparing your own blends.
• Tinctures and alcohol extracts – glass does not react with alcohol and the dropper makes it easier to dispense small amounts.
• Samples and test batches – the small volume is enough for trial recipes that are evaluated over several weeks.

How the dropper works

The dropper consists of a glass tube, a silicone bulb, a white plastic thread and a gold aluminium shell. The tube reaches almost to the bottom of the bottle, so the product can be drawn up even when the contents are running low. When dispensing, tilt the bottle slightly, squeeze the bulb and, once you release it, the contents are drawn into the tube. The size of the drop depends on the viscosity of the product: thicker oils form larger drops, while water-based serums form smaller and faster ones.

The dropper seals via the thread. When transporting the bottle, keep it upright; the dropper is not designed as a travel closure and may leak under prolonged pressure from the contents.

Good to know

Nominal and total volume. The nominal volume is the amount the bottle is designed for under normal filling. The total volume to the brim is the physical volume up to the neck. The difference between them leaves room for the dropper tube, which pushes part of the contents upwards once screwed in, and for the expansion of the contents with temperature changes. Fill to the nominal volume, not to the brim.

Reuse. Once empty, the glass can be washed and used again. For the dropper, check the silicone part, which may change over time with frequent contact with concentrated essential oils or solvents. With such contents it is more sensible to replace the dropper than to risk leaking.

Glass and heat. Do not fill the bottle with hot contents and avoid sudden temperature changes, for example moving it straight from the fridge to hot water. Let oils and serums cool to room temperature before filling.

Other closures. You will find replacement droppers, caps or sprayers with the same neck type, as well as ready-made combinations, in the Handymade range. If you put together your own combination, we recommend checking the tightness and the behaviour of the packaging with your specific formulation.
