Gloss Black Glass Bottle, White Safety Cap & Dropper, 10 ml

This glossy black 10 ml glass bottle with a plastic dropper insert and a white cap with an 18/410 neck finish is used for packaging small quantities of liquid preparations that are dispensed drop by drop. The black glass hides the contents and protects them from light. It is particularly suitable for essential oils and their blends, facial oils, concentrated serums, perfume oils and samples. The set is supplied as a whole, and both the dropper insert and the cap are matched to the neck of the bottle, so you do not need to buy them separately.

What the set is suitable for

The small volume and dark glass suit preparations that are used slowly and drop by drop. The colour of the contents is not visible, so the packaging looks uniform regardless of what is inside.

• Essential oils and blends – with the dropper insert you can measure an exact number of drops into a diffuser, a massage oil or a formulation.
• Facial and hair oils – suitable for oils that are sensitive to light and oxidation.
• Concentrated serums and active blends – contents that are applied in a small amount are dispensed without pouring.
• Perfume oils and samples – a common size for testing a fragrance or for customer samples.

How the set dispenses and seals

The short dropper insert is pushed straight into the neck of the medicine bottle. When you tilt the bottle, one drop at a time comes out. The cap is screwed onto the 18/410 thread and presses against the dropper insert, which also prevents the contents from leaking out on their own when the packaging is turned upside down in a bag or a parcel.

The dripping speed depends on the viscosity of the contents. Thin essential oils and alcohol solutions drip quickly, while thick oils and serums with glycerine drip more slowly. For your own formulation, we recommend checking that it dispenses the way you need.

Nominal and total volume

The nominal volume of 10 ml is the volume the medicine bottle is designed for under normal filling. The total brimful volume is larger and you will find it in the parameters. The difference provides a reserve for the dropper insert, which takes up part of the neck once inserted. For this reason, fill the bottle to the nominal volume, not to the brim. If you fill the bottle up to the neck, the dropper insert will push the contents out when you insert it.

Good to know

The set as a whole is declared suitable for contact with cosmetic products. Only the glass medicine bottle on its own has a certificate for direct contact with food; the dropper insert and the cap do not have one.

The dropper insert is made of polypropylene and the cap of polypropylene and polyethylene. For concentrated essential oils, alcohol solutions or preparations containing solvents, we recommend checking how the dropper insert behaves with your specific formulation, for example whether it changes shape and whether it still seals.

After thorough washing and disinfection, the medicine bottle can be reused. The dropper insert is removed from the neck by pulling; when cleaning it, rinse it with warm water and ethanol. If it has changed shape or no longer fits tightly, replace it, otherwise the packaging will stop sealing. Glass is sorted as glass waste and the plastic parts as plastic.

You will find other closures with the same 18/410 neck finish and ready-made bottle + closure combinations in the Handymade range. For your own combination, we recommend checking the tightness and dispensing with your specific formulation.
