If there are children in your home and you work with concentrated essential oils or herbal tinctures, choosing the right container is both a quality and a safety question. This pack of 88 cobalt blue 50 ml dropper bottles is fitted with child-resistant caps: the dual protection — deep cobalt glass plus a safety mechanism — provides a sound foundation for those running a responsible artisan workshop or home laboratory.
What is included in the 88-piece pack
The pack contains 88 cobalt blue glass dropper bottles of 50 ml each, every one fitted with a child-resistant cap. Bottle height is approximately 100 mm, diameter approximately 42 mm, with a standard GL18 neck. The net weight per bottle with cap is around 70 g, and the total gross weight of the pack is approximately 6.8 kg. A built-in dropper insert in the centre of each cap allows for drop-by-drop dispensing when the bottle is tilted.
Cobalt blue glass and light protection
Cobalt blue glass filters a wider portion of visible light than amber while still providing full UV protection. Sensitive volatile compounds — such as the terpenes of citrus essential oils or the unsaturated fatty acids of cold-pressed oils — oxidise when exposed to light. The deep cobalt colour significantly slows this process, so preparations stored in these bottles retain reliable quality for longer. Glass is also chemically inert: it releases no plasticisers, does not react with essential oils, and remains odour- and taste-neutral.
Child-resistant cap — the safety mechanism
The child-resistant cap opens using a push-and-turn mechanism following the principles of EN ISO 8317: first press the cap down, then turn it anticlockwise. For an adult who knows how the cap works, this is a matter of a few seconds; for small children, it is difficult to figure out. It is a responsible choice for bottling any cosmetic, herbal preparation, or essential oil blend that will be kept in a home environment near children.
Areas of use
- Safe bottling of concentrated essential oil blends
- Family-appropriate packaging of botanical tinctures and herb extracts
- Home-made natural cosmetics, serums, body oils
- Aromatherapy formulations for households with children
- Safe storage solutions for DIY projects and artisan workshops
Cleaning and reuse
Before first use, wash the bottles with warm soapy water and rinse thoroughly. Essential oil residues are most effectively removed with isopropyl or food-grade alcohol. Remove the child-resistant cap from the bottle and clean it separately — residue inside the mechanism can over time impair its operation. Avoid the dishwasher. With appropriate care, the bottle and cap can be reused for many years.
