Amber Glass Bottle, Matte Black Dropper With Shiny Strip, 15 ml

The 15 ml amber glass medicine bottle with a black dropper is used for filling and dispensing liquid cosmetic products that are applied drop by drop. The dark glass reduces the amount of light reaching the contents, which you will appreciate with vegetable oils, oil serums and concentrates of active ingredients that lose effectiveness faster in light. The dropper with a matte black cap and a glossy stripe gives the small bottle a uniform dark look that suits both your own brand and samples for customers. The 15 ml volume suits products that are used in small doses and are used up before they can spoil.

The set consists of a glass bottle and a dropper with a plastic threaded cap, a glass tube and a silicone head. Both parts are declared as suitable for contact with cosmetic products. The set is not approved for food use.

What it is suitable for

• Facial and oil serums – draw up a few drops with the dropper and apply them directly to the skin or into the palm of your hand without tilting the bottle.
• Essential oil blends in a carrier oil – amber glass slows the light-induced degradation of sensitive components, and dispensing drop by drop matches the way these blends are used.
• Concentrates of active ingredients and water-based serums – the dropper works with both oil-based and water-based contents, but check the compatibility of the plastic and silicone parts with your specific formulation.
• Oil for nails, beards and hair ends – the small volume and precise dispensing suit products of which only a few drops are used at a time.
• Samples and test batches – 15 ml is enough to try out a formulation or to provide a presentation sample for a customer.

Nominal and total volume

The nominal volume of 15 ml is the amount the medicine bottle is designed for in normal filling. The total brim-full volume given in the parameters is the physical volume of the glass up to the neck. The difference between them forms a reserve for the glass tube of the dropper, which pushes part of the contents upwards when screwed in, and for the expansion of the contents with changes in temperature. The bottle should therefore be filled up to the nominal volume. If it is filled to the brim, the contents will overflow through the thread once the dropper is fitted and the neck will not seal properly.

Working with the dropper

The length of the dropper is matched to this medicine bottle. The glass tube reaches deep enough for the contents to be drawn up even at a lower level. Dispense by squeezing the silicone head, immersing the tube and releasing it slowly. With thicker oils the tube fills more slowly and the drops are larger. When using it for the first time, therefore, check how many drops correspond to one dose. Tighten the thread of the cap by hand only. If it is overtightened, the plastic thread can become deformed and the seal will deteriorate.

If you want to close the medicine bottle in a different way, you will find closures with the same neck type as stated in the parameters, and ready-made combinations of packaging with closures, in the Handymade range. If you choose your own combination, we recommend checking the tightness and the behaviour of the packaging with your specific formulation.

Good to know

Glass and temperature. Do not fill hot contents into the medicine bottle. A sudden change in temperature, for example a hot filling in cold glass, can crack the bottle. Oil blends and serums should be filled once they have cooled to room temperature.

Plastic, silicone and aggressive contents. The cap of the dropper is made of polypropylene and the head of silicone. With pure essential oils, a higher proportion of alcohol or solvents, test on a single bottle before producing a larger batch whether these parts soften, swell or change shape after several weeks. The glass tube and the bottle itself do not usually have a problem with such contents.

Reuse. The amber glass medicine bottle can be used again after washing and disinfection. With the dropper, it is worth checking the elasticity of the silicone head and the condition of the thread; if it is worn, the whole dropper is replaced.

Recycling. The glass bottle belongs in glass recycling. The dropper consists of plastic, glass and silicone, so the glass tube should be separated from the plastic cap before disposal.
