Tamper Evident Glass Dropper, White, 84 mm

White dropper with safety ring is a closure for glass bottles with an 18/415 neck that dispenses liquid cosmetic products precisely drop by drop. It is particularly suitable for facial serums, oil blends, tinctures and concentrated active ingredients, where a small and repeatable amount per use matters. The white cap with a silicone bulb and glass tube is complemented by a safety ring that detaches upon first opening, so the customer can immediately see that the bottle has not been opened.

What the dropper consists of and how it works

• White PP cap – screws onto the bottle neck, holds the entire dropper in place and seals the contents against spilling.
• Silicone bulb – squeezing and releasing draws liquid into the tube, squeezing again releases it drop by drop. Silicone retains its shape even with frequent use.
• Glass tube – guides liquid from the bottle to the tip. Glass does not react with common cosmetic ingredients, making it suitable for oils, essential oils and alcohol-based tinctures.
• Safety ring – detaches when the cap is first unscrewed and remains on the bottle neck. It serves as visible proof of first opening, which is particularly valuable when selling finished products.

Which products is it suitable for

The dropper makes most sense for products with low to medium viscosity that are dispensed in small amounts: facial and hair serums, blends of vegetable and essential oils, nail and cuticle oil serums, tinctures, concentrates of active ingredients and samples. Thick emulsions, high-viscosity gels or products with particles will not pass through the dropper, or will dispense unevenly.

The length of 84 mm is chosen so that the glass tube reaches almost to the bottom of a bottle of corresponding height. Only then can the last remaining content be drawn up. When choosing, compare the length of the dropper with the height of the bottle you intend to use. Bottles with the same neck type and ready-made bottle + dropper combinations are available in the Handymade range. For your own combination, we recommend verifying the seal and dropper behaviour with your specific formulation.

What is good to know

Preparation before first filling. Before use, we recommend rinsing the glass tube with clean water, disinfecting with isopropyl alcohol or ethanol and allowing to dry completely. The silicone bulb only needs to be wiped on the outside; prolonged soaking in solvents is not necessary.

Hygiene during use. The tip of the tube should not touch the skin or fingers. With each draw, some air and potential contaminants re-enter the bottle. Water-based and water-oil products in a dropper bottle therefore require effective preservation just as they do in any other container. Anhydrous oil blends are less demanding in this regard, but it is also advisable to protect them from oxidation with an antioxidant.

Material compatibility. Glass and PP tolerate oils, ethanol and common active ingredients. The silicone bulb does not come into direct contact with the contents during storage, but it does come into contact with the liquid and its vapours during drawing. For products with a high proportion of essential oils or other strong solvents, we therefore recommend monitoring the bulb's behaviour over time.

Repeated use. The dropper can be washed, disinfected and reused; however, the safety ring works only once. When refilling, it will no longer indicate first opening, but the dropper will continue to seal and dispense normally.

Contact with cosmetics. The packaging is suitable for use with cosmetic products and meets the applicable requirements. A declaration of conformity is available with the product. This closure is not declared for food contact.

Recycling. The dropper consists of multiple materials. Where possible, separate the glass tube from the plastic cap and silicone bulb and dispose of each part separately according to its material.
