The 100 ml format typically holds larger, more concentrated preparations: body oils, massage oils, herbal tinctures, hydrosols. In a household with children, closing these with an appropriate safety cap is a baseline expectation. This pack of 70 cobalt blue 100 ml dropper bottles is fitted with a child-resistant cap: light protection and the safety mechanism together make this a responsible choice for any artisan workshop or home laboratory where preparations are kept near children.
What is included in the 70-piece pack
The pack contains 70 cobalt blue glass dropper bottles of 100 ml each, every one fitted with a child-resistant cap with a central dropper insert. Bottle height is approximately 130 mm, diameter approximately 52 mm, with a standard GL18 neck. The weight per bottle with cap is around 120 g, and the total gross weight of the pack is approximately 9.24 kg. The dropper insert provides even drop-by-drop dispensing when the bottle is tilted, with no spillage.
Cobalt blue glass and light protection
Cobalt blue glass effectively filters UV radiation as well as the shorter wavelengths of visible light. This is particularly important for 100 ml preparations that may stand on a shelf for several months: body oils, serums, herbal tinctures. The deep cobalt colour significantly slows photo-oxidation and preserves active ingredient content. The glass is chemically inert and contains no plasticisers, phthalates, or BPA.
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 100 ml cosmetic, herbal preparation, or essential oil blend that will be kept in a home environment near children.
Areas of use
- Safe long-term storage of concentrated essential oil blends
- Herbal tinctures and botanical extracts in a family environment
- Active-ingredient serums, body oils in households with children
- Responsible bottling of aromatherapy formulations
- A safety-focused storage solution for small artisan workshops
Cleaning and reuse
Rinse new bottles with warm soapy water and let them dry completely. Fragrance residue is most effectively removed with isopropyl or food-grade alcohol. Remove the child-resistant cap from the bottle and clean it separately — essential oil residue trapped in the internal mechanism can over time impair its operation. Avoid the dishwasher. With appropriate care, the bottle and cap can be reused for many years.
