Clear Glass Bottle, Black Tamper Evident Dropper, 10 ml

The clear 10 ml glass bottle with a black dropper is used for filling and precise drop-by-drop dispensing of liquid cosmetic products. Clear glass lets you see the contents, so you can keep an eye on the colour of the oil or serum and see at once how much product is left in the bottle. The dropper takes up exactly as much as your formulation or application requires, which is especially useful for concentrated products of which only a few drops are used.

The set is declared suitable for contact with cosmetic products, and the declarations of conformity for the bottle and the dropper are attached to the product. The set is not intended for food.

What the set is suitable for

The small volume and drop-by-drop dispensing make this bottle a good packaging choice for products that are applied in small amounts or added to other products:

• Facial and oil serums – the dropper applies a few drops directly to the skin or the palm of your hand without spilling the contents.
• Blends of essential oils in a carrier oil – diluted fragrance blends for massage or the bath are dispensed by the drop, and 10 ml lasts for a long time.
• Liquid active ingredients and concentrates – when adding them to a cream or toner, working by the drop is more precise than pouring.
• Samples and travel sizes – a volume of 10 ml corresponds to a trial size of a serum or oil, which a customer can try before buying a larger pack.
• Tinctures and alcohol extracts – glass does not react with alcohol, but check how the dropper behaves during longer contact with alcohol.

How the dropper dispenses

The dropper consists of a glass tube, a black screw closure and a squeezable part that draws the contents in and then releases them drop by drop. The tamper-evident ring serves as a first-opening check, which matters when selling finished products.

Thin oils and aqueous solutions are drawn up easily. Thicker serums, for example gel serums with a higher share of thickener, are drawn up more slowly and the drops tend to be larger. With such formulations, test whether the dropper dispenses the way you need.

Nominal and total volume

The nominal volume is the amount the bottle is designed for under normal filling. The brimful capacity is the physical volume up to the neck and can be found in the parameters. The difference between them leaves room for the dropper, which takes up part of the space once screwed on, and for slight expansion of the contents when the temperature changes.

Good to know

Clear glass lets light through, so it does not protect the contents from it. Store oils with a higher share of unsaturated fatty acids, essential oils and serums with sensitive active ingredients away from direct light, or choose dark glass for them.

Before the first filling, wash the bottle and the dropper, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in the dropper would dilute an oil-based product and, in unpreserved water-based products, would promote the growth of microorganisms.

Glass withstands ordinary cleaning and repeated use. The plastic and silicone parts of the dropper may soften or lose their elasticity over time in long-term contact with concentrated essential oils or with a higher share of alcohol. With such contents, monitor how the dropper behaves over time and how well it seals.

Closures with the same type of neck as this bottle, and other ready-made bottle + closure combinations, can be found in the Handymade range. If you make your own combination, check the seal and the behaviour of the packaging with your specific formulation.

At the end of its life, the glass bottle belongs in glass recycling. The dropper consists of glass, plastic and silicone, so take it apart before disposal and sort the individual parts separately.
