Amber Glass Bottle, Gold Black Dropper, 5 ml

A glass bottle, dropper vial with a black-gold dropper, 5 ml is a complete packaging and closure set for small quantities of concentrated preparations dosed by drops. Amber glass protects the contents from light, and the dropper delivers exactly as much as the formulation or application requires. The set is declared as suitable for contact with cosmetics.

At a nominal volume of 5 ml, this is packaging for samples, testers and small batches. Suitable for facial serums, essential oil blends, fragrance oils, nail and cuticle oil serums, or concentrates of active ingredients that are diluted only at the time of use.

Why amber glass and a dropper

• Light protection – amber glass reduces light exposure to the contents. This is important for essential oils, vegetable oils with a higher proportion of unsaturated fatty acids, and for active ingredients sensitive to oxidation.
• Precise dosing – the dropper draws the contents drop by drop, making it suitable for preparations used in small amounts or dosed further into another formulation.
• Chemically stable material – glass does not react with common cosmetic ingredients, does not absorb fragrances, and is unaffected by oils or alcohol solutions.
• Finished product appearance – the black-gold dropper with a metal ring gives even a small sample the look of a finished product, which you will appreciate in gift sets and when presenting your own brand.

Suitable for products such as

The set is best suited for oil-based and alcohol-based contents with low to medium viscosity, which the dropper easily draws up and doses precisely:

• facial and eye serums on an oil base, skin care blends in minimal packaging;
• pure essential oils and their blends, aromatherapy concentrates;
• fragrance oils and samples of your own scents;
• nail and cuticle oil serums, beard oils;
• tinctures and water-alcohol concentrates of active ingredients;
• serum samples and testers for customers before purchasing full-size packaging.

For thick oils, balms and emulsions with higher viscosity, the dropper is less suitable. The contents draw up slowly and drops form unevenly.

Filling and the difference between nominal and total volume

The nominal volume is the quantity the bottle is intended for under normal filling. The total volume to the brim is the physical volume of the glass up to the neck and is higher. The difference between them is the reserve for the dropper: the glass tube occupies part of the space once screwed in, and the contents may expand slightly when warmed. The bottle should therefore be filled to the nominal volume, not to the brim; otherwise, when the dropper is screwed in, some of the contents will be pushed out through the neck. The exact values of both volumes can be found in the product parameters.

Working with the dropper

The dropper consists of a silicone bulb, a metal ring and a glass tube. The length of the tube is matched to the height of the bottle, so it reaches almost to the bottom and the last of the contents can be drawn up. To draw up, squeeze the bulb above the surface, submerge the tube in the contents, and release the bulb. The drop is then dispensed by a gentle squeeze. Drop size depends on the viscosity and surface tension of the contents – it differs for oils compared to alcohol solutions.

When combining with a different closure or using the dropper on another bottle with the same neck type, we recommend verifying the seal, dosing, and packaging behaviour with the specific formulation. Additional closures for this neck and ready-made combinations can be found in the Handymade range.

Good to know

• Preparation before first filling – wash the bottle and the dropper tube, disinfect with isopropyl alcohol or ethanol and allow to dry completely. Any remaining water in an oil-based product can shorten its shelf life.
• Reuse – the glass and the dropper can be reused after thorough washing and disinfection. The silicone bulb can retain strong fragrances; when changing the contents, it is better to replace the dropper.
• Essential oils and elastic parts – glass does not react with concentrated essential oils, but with prolonged contact some components may affect the silicone and plastic parts of the bulb. For pure essential oils stored over longer periods, check the dropper periodically and store the bottle upright.
• Labelling – narrow labels hold best on the small diameter, or a neck tag.
• Glass and temperature – do not pour hot contents into a cold bottle and vice versa; a sudden temperature change can damage the glass. Allow the contents to cool to room temperature before filling.
• Recycling – the bottle belongs in glass waste once the dropper has been removed. The dropper combines several materials and should be sorted according to the predominant material.
