Amber Glass Bottle, White Safety Cap & Dropper, 30 ml

Amber glass medicine bottle, 30 ml with an 18/410 neck finish, supplied as a set with a plastic dropper insert and a white cap. The amber glass limits the amount of light reaching the contents, the dropper insert dispenses drop by drop and the cap seals the whole set. The set is suitable for face and body oils, oil serums, essential oils, tinctures and other liquid preparations where precise dispensing and protection from light matter.

The set as a whole is declared suitable for contact with cosmetic products.

What it is suitable for

• Oils and oil serums – the small volume means you only have as much product open at any one time as you actually use, and the amber glass limits the effect of light on sensitive oils.
• Essential oils and fragrance blends – the dropper insert dispenses drop by drop, so they are easier to measure into recipes and diffusers.
• Tinctures and alcohol extracts – the glass is resistant to alcohol and the cap keeps the contents in place during normal storage.
• Samples and test batches – 30 ml is enough to try out a recipe before a larger production run.

How to work with the set

The bottle is filled to the nominal volume, not to the brim. The nominal volume is the volume the packaging is designed for under normal filling. The brim-full volume is the physical volume of the bottle up to the neck, and you will find it in the parameters. The difference between the two values provides a margin for the dropper insert and for the expansion of the contents when the temperature changes.

After filling, press the dropper insert into the neck and screw the cap onto the thread. The contents are dispensed by tilting or inverting the bottle. The dripping speed depends on the viscosity of the contents: thick oils flow slowly through the dropper insert, thinner liquids faster.

Good to know

Before the first filling, we recommend washing the bottle, disinfecting it with isopropyl alcohol or ethanol and letting it dry completely. Otherwise, residual water in the neck or at the bottom would get into an anhydrous product.

Glass does not tolerate sudden temperature changes. Let hot contents cool to at least lukewarm before filling, and do not put the bottle straight from a cold environment into hot water.

The dropper insert is made of polypropylene and the cap combines polypropylene and polyethylene. With concentrated essential oils, fragrance compositions and solvents, we recommend checking how the dropper insert behaves with your specific formulation, especially during longer storage.

After washing and disinfecting, the bottle can be reused. The dropper insert and cap are harder to clean, so when switching to a different type of product it is better to replace them with new ones. Glass belongs in the glass recycling bin, the dropper insert and cap in plastics.

Closures with the same neck type as stated in the parameters, and other ready-made combinations of bottle and closure, can be found in the Handymade range. If you combine components yourself, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.
