Amber Glass Bottle, Slim, Black Cap with Inner Dropper, 50 ml

A brown glass dropper bottle with a black cap is a complete ready-to-fill set for liquid cosmetic preparations in a 50 ml volume. Brown glass reduces light exposure to the contents, which is valuable for essential oils, oil blends and serums whose components oxidise rapidly under light. The dropper inserted into the neck releases the contents drop by drop, allowing precise dosing without unnecessary contact with air.

The tall, slim shape of the bottle fits comfortably in the hand, takes up little shelf space and leaves enough surface area for a label. The set is suitable for small-scale producers and home formulators who need a sealed and ready-to-use container without assembling individual parts from different sources.

What makes the set practical

• Light protection – brown glass transmits less light than clear glass, which slows the oxidation of sensitive oils, vitamins and fragrance components. It does not replace an antioxidant in the formulation, but complements it.
• Drop-by-drop dosing – the dropper is inserted into the neck and releases the contents gradually when the bottle is tilted. The customer takes exactly as much as needed, and fingers or contaminants cannot enter the bottle.
• Chemically inert glass – glass does not absorb fragrances, does not discolour and does not release any components into the contents. This is important with concentrated essential oils and alcohol-based preparations.
• Consistent appearance – the brown bottle with a black cap looks understated and suits both dark and light labels without adjusting the cap colour.
• Reusable – glass can be refilled after thorough washing and disinfection. We recommend replacing the dropper and cap with new ones when changing the contents.

Suitable for products such as

The dropper works best with thin, low-viscosity contents. The set is therefore most suitable for:

• essential oils and fragrance blends for aromatherapy or diffusers,
• facial and hair oils, oil serums and blends of carrier oils with essential oils,
• aqueous and water-glycerin serums with lower viscosity that are applied drop by drop,
• alcohol tinctures, herbal extracts for cosmetic use and tonics in travel size,
• samples and test batches where you want to track consumption precisely.

Thicker oils, butters in liquid state or serums thickened with gums flow through the dropper slowly or not at all. For such contents, a bottle with a pump or without an insert is more suitable.

Nominal and total volume

With a dropper bottle you will encounter two volumes. The nominal volume is the volume for which the container is intended at standard filling, and this is the figure stated on the label. The total volume to the brim is the physical volume up to the neck. The difference between them forms a reserve for the dropper, which when inserted into the neck is submerged in the contents, and for the expansion of the liquid with changes in temperature. The bottle is therefore filled to the nominal volume, not to the brim. Exact values for both volumes can be found in the product parameters.

Preparation and filling

Before first use, wash the bottle with warm water, optionally with a mild detergent, and rinse with clean water. Then disinfect the inside with isopropyl alcohol or ethanol and leave to air-dry upside down. Residual moisture in an oil-based preparation causes cloudiness and creates an environment for microorganisms. The dropper and cap can simply be sprayed with alcohol and left to evaporate.

The neck of the bottle is narrow, so when filling small batches a narrow funnel or a dosing pump with a nozzle helps. Apply the label to a dry and degreased surface.

What is worth knowing

The set as a whole is intended for cosmetics. All three components are declared as suitable for contact with cosmetic products. The food-contact declaration applies only to the glass bottle individually; the dropper and cap do not have it. We therefore do not recommend the set for food use. The declaration of conformity is available at the product.

The dropper and cap are made of plastic. They are used as standard with common cosmetic oils, essential oils and alcohol tinctures. With aggressive solvents or concentrated substances outside cosmetics, we recommend verifying the material's behaviour with the specific formulation. Glass tolerates heat, but do not fill hot contents into a cold bottle. A sudden change in temperature may damage it.

Closures with the same neck type stated in the parameters, and other ready-made combinations, are available in the Handymade range. When combining parts yourself, we recommend verifying the seal, dosing and container behaviour with the specific formulation.

After use, glass is recycled as packaging glass and plastic components separately as plastic.
