The 30 ml cobalt blue glass dropper bottles combined with child-resistant caps provide extra safety for storing preparations that may pose a risk to children — particularly concentrated essential oils and botanical tinctures. This 110-piece pack is intended for aromatherapy artisans, cosmetic formulator small business owners, and makers of therapy-support products.
What is included in the 110-piece pack
110 cobalt blue glass dropper bottles, each with a nominal 30 ml fill capacity and a matching child-resistant cap. The height of one bottle is approximately 85 mm and the diameter is 35 mm. The total gross weight of the pack is around 6.05 kg, and an empty bottle with cap weighs approximately 60 g together. The standard GL18 thread allows the cap to be swapped for another type if needed.
Cobalt blue glass and the benefit of light filtering
Cobalt blue glass absorbs not only the UV range but also part of the shorter visible wavelengths — particularly blue and green light. This extended protection provides longer shelf life for light-sensitive preparations and helps to preserve the original active ingredient content and scent profile of essential oils. The glass is chemically inert and contains no BPA or plasticisers.
The mechanism of the child-resistant cap
The child-resistant cap works on the press-and-turn principle: the cap must be pressed down while being turned. This two-step movement is simple for adults but difficult for small children to perform, reducing the risk of accidental opening. The mechanism complies with the CR (Child-Resistant) standard and is particularly recommended for preparations that could pose a risk if a child were to ingest them — such as concentrated essential oils, alcohol-based tinctures, or certain botanical extracts.
Areas of use
- Safe storage of concentrated essential oils and aromatherapy blends
- Bottling botanical tinctures and alcohol-based extracts
- Retail sale of therapy-support and wellness preparations
- Filling herb-based serums and oils
- DIY beauty products and own-brand creation for small business owners
Cleaning and reuse
The bottles and caps can be rinsed in warm soapy water before and after use. For stubborn scent residue, pure ethyl alcohol (70%) is recommended. The child-resistant mechanism is not damaged by alcohol, but it is worth drying it thoroughly so that the closure mechanism continues to operate smoothly. Avoid dishwasher use if there is a label or printed surface on the bottle.
