Gloss Black Glass Bottle, Glossy Silver White Dropper, 50 ml

The 50 ml glass bottle with dropper, in a glossy black finish, is a complete packaging set for oil serums, facial and hair oils and active ingredient concentrates that are dispensed drop by drop. The opaque black glass blocks light and so protects light-sensitive contents, such as vegetable oils or blends with essential oils. The glossy silver dropper with a collar in the same shade completes the packaging, which also suits small batches intended for sale.

The whole set is declared suitable for contact with cosmetics. The bottle on its own also has a certificate for direct food contact, while the dropper does not, so the set as a whole is intended for cosmetic products.

What it is suitable for

• Oil serums and facial oils – the 50 ml volume corresponds to a common pack size, and the dropper lets you apply a few drops without spilling.
• Hair and beard oils – thicker oils are drawn into the dropper more slowly, but they are dispensed more precisely than from a bottle with an ordinary cap.
• Concentrates and essential oil blends for dilution – the dark glass limits exposure to light, to which these ingredients are sensitive.
• Samples and test batches – when developing a formulation, it helps to have packaging from which you can dispense repeatedly and without touching the contents by hand.

How to fill and dispense

The bottle has a medicine bottle shape with a narrow neck, so it is filled with a funnel or from a container with a spout. After filling, the dropper is screwed on and tightened by hand, without tools. The glass tube of the dropper has a length adapted to this bottle, so the contents can be drawn up even when the level is low. The squeeze bulb is made of silicone.

The nominal volume is the volume the packaging is designed for under normal filling. The brimful volume is the physical space up to the neck and is given in the parameters. The difference between them forms a reserve for the submerged tube of the dropper and for expansion of the contents with temperature changes. Therefore fill up to the nominal volume, not to the brim, otherwise the contents will overflow when the dropper is screwed on.

Good to know

Through the black glass you cannot see the level of the contents. When the pack is nearly finished, it helps to shake the bottle occasionally or to draw up a trial dose with the dropper.

The dropper is made of several materials: an aluminium collar, a plastic inner thread, a silicone squeeze bulb and a glass tube. For formulations with a high proportion of essential oils or solvents, we recommend checking how the silicone bulb tolerates long-term contact with the specific formulation.

After thorough washing and disinfection, the bottle can be reused. When reusing the dropper, replace it if the silicone part has lost its elasticity or changed colour. You will find closures with the same neck type and other ready-made combinations in the Handymade range. If you combine the bottle with a different closure, we recommend checking the tightness and dispensing with the specific formulation.

The glass bottle belongs in glass recycling. The dropper contains metal, plastic, silicone and glass, so separate it from the bottle before recycling.
