Amber Glass Bottle, Black Tamper Evident Dropper, 15 ml

A glass bottle with a dropper in a volume of 15 ml is a small set designed for concentrated cosmetic preparations that are dispensed drop by drop. Brown glass protects the contents from light, and the dropper measures out small amounts without your fingers touching the contents. It is particularly suitable for facial serums, oil blends, essential oil mixtures in a carrier oil, tinctures, and concentrated active ingredients that are added to formulations in small doses.

The bottle has the shape of a medicine bottle with a straight body and a narrower neck, so it is easy to hold in the hand and a label can be applied to it. The black dropper cap has a tamper-evident ring that separates from the closure on first opening. The customer can see at a glance that the product has not been opened, which is especially useful when selling finished cosmetics.

How the set works

• Protection from light – brown glass reduces the penetration of daylight, which slows down the oxidation of oils and the degradation of sensitive active ingredients. For blends with essential oils, vitamins, or plant extracts, dark glass is more suitable than clear.
• Precise dosing – the dropper measures out one or several drops without spilling, which is practical for serums and concentrates where only a small amount is applied to the skin.
• Hygienic application – the drop is applied directly to the skin or to the palm, and the contents do not touch fingers. For leave-on products with lighter preservation, this reduces the risk of introducing contaminants.
• Tamper-evident ring – it breaks on first opening and serves as proof of integrity for the end customer.
• Glass resistant to the contents – the glass tube of the dropper and the glass body of the bottle come into contact with the preparation. The set is therefore also suitable for oil-based and alcohol-based contents, which could damage a plastic container over time.

The length of the dropper is matched to the height of the bottle, so the tube reaches almost to the bottom and the contents can be used up without tilting.

Suitable for products such as

The set is designed for cosmetic products and is declared as suitable for contact with cosmetics. In practice it is used for:

• facial and hair serums on both oil and water base,
• essential oil blends diluted in a carrier oil, for example for facial massage or cuticle care,
• beard and moustache oils,
• concentrates of active ingredients that are added to creams drop by drop,
• tinctures and alcohol extracts for cosmetic use,
• samples and test packaging where a small volume is sufficient.

For water-based serums, the dropper limits the contact of the contents with air and fingers. However, preservation of the water-based formulation is still necessary — the packaging does not replace it.

Nominal and total volume

The bottle has a nominal volume, meaning the volume it is designed for under normal filling conditions, and a higher total brim capacity, which corresponds to the physical space up to the neck. The difference between them is a reserve for the dropper tube, which pushes some of the contents upward when screwed in, and for the expansion of the contents with temperature changes. Both values can be found in the product specifications.

What is good to know when filling and using

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

Seal of the set. The dropper screws onto the thread of the bottle. When using a specific formulation for the first time, we recommend leaving the filled bottle on its side for a few days and checking that the contents do not leak. This applies especially to thin oils and alcohol-based solutions.

Essential oils and the silicone bulb. The dropper tube is made of glass, the bulb of silicone. During normal use, the contents do not come into contact with the bulb. However, if you store the bottle in a tilted position or turn it upside down for extended periods, the concentrated blend may enter the bulb. Therefore, after use, allow the dropper to drip freely and store the bottle upright.

Reuse. The glass can be washed and used again. After first opening, the dropper loses its function as proof of integrity, but the dosing continues to work. When changing the contents, rinse the dropper thoroughly so that residues of the previous formulation do not get into the new one.

Glass and temperature. Do not fill the bottle with hot contents and do not expose it to sudden temperature changes. Oil serums are filled after cooling, ideally at room temperature.

Labelling. The straight body of the bottle is suitable for applying a label. For oil-based products, use a label with a strong adhesive that will not come off if accidentally contaminated with oil.

Recycling. The bottle is glass and after cleaning belongs in the glass recycling bin. The dropper is a composite product made of plastic, silicone, and glass, and should therefore be sorted separately from the bottle.

Closures with the same neck type as listed in the specifications, as well as other ready-made bottle + closure combinations, can be found in the Handymade range. For custom combinations, we recommend verifying the seal, dosing, and packaging behaviour with the specific formulation.
