Gloss Black Glass Bottle, Gold Black Dropper, 100 ml

This is a ready-made set consisting of a glass bottle with a capacity of 100 ml and a dropper, designed for precise dispensing of liquid cosmetic preparations. The black glossy glass is opaque, protecting the contents from light and helping maintain the stability of light-sensitive substances. The black and gold dropper forms a contrasting yet visually unified combination with the bottle, suitable for private label as well as gift packaging.

The set is particularly suitable for facial serums, oil serums, carrier and botanical oils, hair and beard oil blends, tinctures, or concentrated active solutions where the precise amount applied to the skin matters. The 100 ml volume corresponds to a standard packaging size for body and hair oils or a larger serum format.

Key benefits

• Light protection – black glass does not transmit light, which is appreciated with oils high in unsaturated fatty acids, essential oils, and active substances sensitive to light.
• Precise dispensing – the dropper allows the contents to be applied drop by drop, without spilling and without unnecessary finger contact with the contents.
• Glass durability – glass does not react with essential oils, alcohol-based extracts, or solvents that may degrade certain plastics.
• Consistent appearance – the glossy black surface and black-and-gold dropper cap form a cohesive whole and carry labels well in light or gold designs.
• Reusability – both the bottle and dropper can be washed and refilled after emptying.

How the set works

The dropper screws onto the neck of the bottle and seals the contents tightly when fully tightened. When the bulb is pressed and released, liquid is drawn up into the glass tube, which is then dispensed drop by drop. The tube reaches almost to the bottom of the bottle, allowing the remaining contents to be used up without tilting.

The dropper is composed of several materials – a glass tube, a flexible silicone bulb, and plastic and aluminium parts of the cap. This is a suitable combination for standard cosmetic formulations. With a high proportion of essential oils or alcohol, we recommend checking how the bulb behaves after prolonged contact with the contents.

Nominal volume and volume to the brim

For every container, we distinguish two volumes. The nominal volume is the quantity the container is designed for when filled normally. The total brim volume is the physical capacity up to the neck and is slightly larger. The difference provides a reserve for the glass tube of the dropper, which displaces some liquid when screwed in, and for slight expansion of the contents with temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim, otherwise the contents will overflow when the dropper is inserted.

Suitable for products such as

• Facial serums on both water and oil bases – drop-by-drop dispensing corresponds to the typical amount applied to the face.
• Face and body oils and oil blends with essential oils, where dark glass slows yellowing and rancidity.
• Beard oils and hair oil serums, where a small amount is applied directly to the ends or scalp.
• Tinctures and alcohol extracts – glass is resistant to alcohol and the dropper allows measuring an exact number of drops.
• Active ingredient concentrates intended to be added to a cream or serum just before use.

The set is not suitable for thick creams, butters, or gels with high viscosity – the tube cannot draw them up and dispensing does not work.

What's good to know

Preparation before first filling. We recommend washing both the bottle and dropper before first use, disinfecting with isopropyl alcohol or ethanol, and allowing them to dry completely. Traces of water in an oil product can cause cloudiness or promote microbial growth.

Opaque glass. Black glass will not show how much contents remain in the bottle, and any change in colour or cloudiness will not be visible through it. For formulations where you want to monitor stability, we recommend keeping a small control sample in clear glass.

Contact with cosmetics and food. The set as a whole is declared as suitable for cosmetic products, and a declaration of conformity is provided with the product. The glass bottle on its own has food contact approval; the dropper does not, so the set as a whole is not intended for food use.

Glass and heat. Glass can withstand normal filling temperatures, but a sudden transition from hot to cold may cause cracking. Allow hot oil phases to cool to at least a lukewarm temperature before filling.

Labelling. The glossy black surface holds self-adhesive labels well. Light, gold, or white print reads best on a dark background.

Closures. If you want to use the bottle with a different closure, select closures with the same neck type as stated in the parameters. Ready-made combinations can be found in the Handymade range. With a custom combination, we recommend verifying the seal and the behaviour of the closure with the specific formulation.

Recycling. Once emptied and washed, the glass bottle belongs in the glass recycling stream. The dropper consists of multiple materials and should therefore be recycled separately from the glass.
