The 50 ml cobalt blue glass dropper bottles are supplied without caps, allowing you to flexibly combine them with the cap type that best suits your own preparations. This 88-piece pack is recommended for essential oil creators, aromatherapy artisans, and cosmetic formulator small business owners who already have their own cap stock.
What is included in the 88-piece pack
88 cobalt blue glass dropper bottles without cap, each with a nominal 50 ml fill capacity. The height of one bottle is approximately 100 mm and the diameter is 42 mm. The total gross weight of the pack is around 6.78 kg, and an empty bottle weighs approximately 70 g. The bottles have a standard GL18 thread and are therefore compatible with standard caps available on the market.
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 preparations sensitive to light. The 50 ml size is particularly suitable for massage oils, body oils, and larger essential oil blends, where longer storage times make light protection especially important.
Why the cap-free format is advantageous
The cap-free version is an ideal choice if you work with your own cap system, or if you want to use the same bottle with different cap types for various preparations. You can pair an aluminium cap for a massage oil, a pipette dropper for a facial serum, and a child-resistant closure for a therapy-support tincture — all on the same bottle. This modular approach reduces stock requirements.
Areas of use
- Bottling massage oils and body oils
- Storing larger essential oil blends and aromatherapy formulas
- Filling perfume bases, colognes, and cosmetic serums
- Dispensing botanical tinctures, hydrosols, and flower essences
- DIY beauty products and own-brand creation for small business owners
Cleaning and reuse
The bottles can be rinsed in warm soapy water before and after use. For stubborn scent residue, pure ethyl alcohol (70%) is recommended. The glass is reusable many times over and recyclable in an environmentally friendly way. Avoid dishwasher use if there is a printed surface or label on the bottle. After complete drying, the bottles can be refilled.
