Green Glass Bottle, Matte White Dropper, 15 ml

The green glass bottle with dropper is a ready-made set for 15 ml of liquid product that is dispensed drop by drop. Glass does not react with the contents, and the green tint filters out some of the light, so the contents remain visible while being less exposed to daylight than in clear glass. The white matte dropper with an 18/410 neck finish screws directly onto the bottle, and the length of its glass tube is matched to the height of the bottle so that it also draws up the remaining contents at the bottom.

This size suits facial serums, oil blends, tinctures and essences, that is, products used in small amounts where precise dispensing without fingers touching the contents matters. The set is declared suitable for contact with cosmetics. It is not intended for food.

What it is suited for

• Facial and hair serums – both water-based and oil-based, where a single dose is counted in drops.
• Oil blends for the face and cuticles – a smaller volume is used up before the oil starts to age.
• Herbal tinctures and alcohol extracts – glass does not react with alcohol, and the green tint dampens light.
• Samples and test batches – 15 ml is enough to try a new recipe before filling larger quantities.
• Essential oil blends for dilution – adding drops to a carrier oil or a diffuser is precise and convenient with a dropper.

Filling and dispensing with the dropper

The bottle has two volumes, and you will find both in the parameters. The nominal volume is the amount the packaging is designed for under normal filling. The total brim-full volume is the physical space up to the neck. The difference between them is a reserve, which in this set is taken up by the dropper tube once screwed in, and which also leaves room for the contents to expand when the temperature changes. For this reason, fill the bottle up to the nominal volume. If it is filled to the brim, the tube displaces part of the contents through the neck.

The dropper consists of a silicone bulb, a plastic closure with a thread and a glass tube. Squeezing the bulb before immersing it fills the tube, and releasing it dispenses the contents drop by drop. The size of a drop depends on the density and surface tension of the contents. A water-based serum forms smaller drops, a thicker oil larger ones. For a recipe where the number of drops matters, we recommend weighing one dose once and noting down the number of drops for the given product.

Good to know

Before first filling, wash the bottle and the dropper, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Residual water in the tube would dilute the first dose and could cause cloudiness in an oil-based product. Follow the same procedure when reusing the set. The glass and the tube withstand repeated washing, but check the silicone bulb. After prolonged contact with pure essential oils or solvents it may soften or lose its elasticity. It is advisable to test how the dropper behaves with a concentrated essential oil blend on a single piece beforehand.

Let a warm product cool down before filling, at least to a temperature you can hold in your hand. Hot contents do not belong in cold glass, as a sudden change in temperature damages the glass.

The bottle has the shape of a medicine bottle with a narrow neck, which limits contact of oil-based products with air. You will find closures with the same neck type and other ready-made combinations of bottle and closure in the Handymade range. If you make your own combination, we recommend checking the tightness and the behaviour of the packaging with your specific formulation. The empty bottle belongs in glass recycling.
