The 15 ml cobalt blue glass bottle with a child-resistant cap is a responsible, refined combination: the light filtering of the cobalt blue glass protects delicately scented essential oils, while the child-resistant push-and-turn mechanism prevents children from accidentally opening the bottle. This pack of 156 is recommended for small essential oil businesses, natural cosmetic developers, ethanol-based tincture makers, and family-friendly household DIY solutions alike.

Cobalt blue glass — UV protection and vintage aesthetics
Cobalt blue glass blocks UV radiation and shorter (blue-green) wavelengths of visible light, which is particularly favourable for storing delicate linalool-based essential oils (lavender, bergamot, ylang, neroli, jasmine). The deep blue tone also lends a characterful vintage apothecary feel. Glass is chemically inert: it does not react with essential oils and contains no plasticisers or other migratable substances.
Child-resistant cap — safety mechanism
The child-resistant cap is designed so that it cannot be opened by a simple twist: the cap must be pushed downwards and only turned while held under pressure. This mechanism is difficult for small children to operate. A sealing disc on the inner surface of the cap provides an airtight closure, so evaporation and oxidation of the contents are also reduced. The 15 ml size is especially well suited to preparations with more concentrated active ingredients (essential oil blends, ethanol-based tinctures, disinfectant solutions) — these are appropriate applications for the CR mechanism. Note that the CR cap's safety mechanism does not replace the basic rule of storing such products out of the reach of children.
Typical areas of use
- Concentrated essential oils and blends in family households
- Home-made natural disinfectants and alcohol-based solutions
- Ethanol-based botanical tinctures and extracts
- Cosmetic solvents and perfume bases stored safely
- Small-business product line CR-compliance support
Cleaning and storage
We recommend rinsing new bottles in warm soapy water before first use, then drying thoroughly. Disassemble the child-resistant cap for cleaning; do not place the sealing disc in a dishwasher. An isopropyl alcohol rinse is the most effective way to remove residual scents. Store filled bottles in a cool, dark place, out of the reach of children.
