The tamper-evident (TE) dropper cap is specifically recommended for those who wish to bottle essential oils, serums or other cosmetic preparations intended for retail — whether for their own webshop or for physical stores. The security ring at the base of the cap clearly indicates if the bottle has previously been opened, so the customer can be sure they are receiving a fresh, untampered product. This 110-piece pack of 30 ml bottles meets the quality and transparency expectations of commercial retail.
What this 110-piece pack contains
110 amber 30 ml glass dropper bottles + 110 TE dropper caps. The bottles are approximately 85 mm tall with a 35 mm diameter. The neck uses a standard GL18 thread. The cap features an integrated dropper insert and a tear-off security ring at the base. The total package weight is approximately 0.77 kg.
Amber glass and UV protection
Amber glass is the category standard in the essential oil and cosmetic segment: it filters out the shorter wavelengths of visible light and most of the UV spectrum, slowing active ingredient degradation. This is particularly important for products that may stand on shelves for extended periods of light exposure — amber glass protects the contents from this light exposure, ensuring the customer receives a well-preserved, high-quality preparation.
TE dropper cap details
The TE cap serves two purposes: a dropper function (via an integrated dropper insert) and tamper indication — a tear-off ring at the base of the cap detaches from the cap upon first opening and remains on the bottle neck. This visibly and tactilely signals whether the bottle has previously been opened — so the customer can be certain they are buying an untampered, fresh product. For retail-bound cosmetic and essential oil products, this kind of tamper-evident solution is the foundation of transparency and consumer trust.
Areas of use
- Bottling of retail-bound essential oil synergies
- Private-label cosmetic products
- Active-ingredient serums in commercial retail
- Supplement-like preparations (with appropriate authorisations)
- Fair and exhibition products where authenticity verification matters
Cleaning and maintenance
Wash the bottle in warm soapy water; do not place the cap in the dishwasher. The TE security ring is single-use: once detached upon first opening, it does not reset, and a new cap is required for subsequent use if you wish to maintain tamper-evident protection. Used bottles can be thoroughly cleaned and refilled with a new cap for personal use; for retail, however, they may only be reintroduced with a fresh TE cap.
