White Glass Bottle, Silver Black Dropper, 15 ml

The white glass medicine bottle with a black and silver dropper is used for filling small volumes of cosmetics that are applied drop by drop. Opaque white glass lets less light through to the contents than a clear bottle, so it suits facial serums, oil serums, blends of vegetable and essential oils, or alcoholic extracts whose stability is shortened by light. The nominal volume of 15 ml suits samples, travel sizes and concentrated products of which the customer uses only a few drops a day.

The set is supplied with the bottle and dropper together, so you do not need to buy a closure separately or check that the thread matches. Both the bottle and the dropper are declared suitable for contact with cosmetics. This set is not approved for contact with food and is intended exclusively for cosmetic products.

What it is suitable for

• Facial serums – both water-based and oil-based, where a few drops are dispensed into the palm or directly onto the skin.
• Oil blends for nails, cuticles and beards – a small amount is applied precisely to the spot without spilling.
• Alcoholic tinctures and concentrates – glass does not react with alcohol, and the dropper measures the dose straight into the base.
• Samples and test batches – a volume of 15 ml is enough to check a recipe or for a gift or trial pack.
• Essential oil blends for a diffuser or for soap – dispensing by the drop suits cases where the number of drops matters.

Dropper and dispensing

In this medicine bottle the dropper reaches almost to the bottom, so the contents can be drawn up even when the level is low. The tube is glass, the bulb is silicone and the black and silver cap combines aluminium and plastic. Squeezing the bulb and releasing it slowly draws up the liquid; a drop is then dispensed by pressing the bulb over your palm or skin. The thread of the dropper matches the neck of the bottle, so nothing needs adjusting.

Drop size depends on the thickness of the contents. A thin water-based serum forms smaller drops than a thick oil or a thickened serum, so it is worth weighing a few drops before setting the dispensing amount.

Volume and filling

Nominal volume is the quantity the packaging is designed for under normal filling, and this is what the bottle is filled to. Total brimful volume 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 dropper tube, which pushes the level up once screwed in, and for expansion of the contents when the temperature changes. If filled to the brim, the contents would overflow when the dropper is fitted and the dropper could not draw up properly.

Before the first filling, wash the bottle and dropper, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in an oil product promotes the growth of microorganisms and in a water-based product dilutes the preservative.

Good to know

• The level is not visible – opaque glass protects the contents but also hides how much product remains. Check the amount by lifting out the dropper.
• Essential oils and concentrates – the glass tube does not react with them. Check how the silicone bulb behaves in longer contact with undiluted essential oils or solvents on your specific blend.
• Reuse – after thorough washing and disinfection you can use the bottle again. The dropper is harder to clean, especially the bulb, so it is safer to use a new one when the contents change.
• Recycling – the bottle belongs with glass. The dropper is made of several materials, so before disposal separate the glass tube from the cap with the bulb.
• Neck – the neck type is given in the parameters. You will find closures with the same neck type and other ready-made combinations in the Handymade range. If you make your own combination, check the seal, the dispensing and how the packaging behaves with your formulation.
