Product description
The glass dropper bottle type M 10 ml is a small container made of amber glass for products that require light protection and drop-by-drop dispensing. Amber glass reduces light penetration, making it particularly suitable for essential oils, fragrance compositions, facial serums, oil concentrates, tinctures, and samples stored or shipped in small quantities. Glass does not react with its contents, does not absorb odours, and tolerates both alcohol and essential oils — a significant advantage over plastic. Dropper bottle refers to the shape of the container, not its intended use.
The container is suitable for use with cosmetic products; the statement of suitability is included in the product parameters.
Suitable applications for the dropper bottle
- Essential oils and fragrance blends – dark glass and small volume match the standard conditions for storing and dispensing these substances drop by drop.
- Serums and oil concentrates – the 10 ml volume is appropriate for higher-value active ingredients applied to the skin in small doses.
- Tinctures and alcohol extracts – glass withstands alcohol without deforming or becoming cloudy.
- Samples and test batches – during formula development or when offering samples to customers, a small bottle is practical and straightforward to ship.
Nominal and total volume
Nominal volume is the quantity for which the container is designed under normal filling conditions. Total volume to the brim is the physical volume of the bottle up to the neck and is higher. The difference provides a reserve for the dropper insert or closure liner and for thermal expansion of the contents. The bottle should therefore be filled to the nominal volume, not to the brim. Both values are listed in the parameters.
If you plan to use a dropper, bear in mind that its glass tube will displace some of the contents. Fill the bottle to the nominal volume, fit the dropper, and check that the contents do not leak through the thread.
Closures
The bottle has a neck with an 18/410 thread. Closures with the same neck finish and ready-made container and closure combinations are available from Handymade. With a custom combination, we recommend verifying tightness, dosing behaviour, and the container's performance with the specific formulation, particularly for essential oils and alcohol-based solutions, which place greater demands on the closure liner.
Useful information
- Before the first fill wash the bottle, disinfect it with isopropyl alcohol or ethanol and allow to dry completely. Residual water would dilute oil-based contents or promote microbial growth in water-based products.
- Reuse is possible; once washed and disinfected, the bottle can be refilled. Glass does not absorb odours, but the cap and its seal do — replace the cap when changing the contents.
- Glass and heat – do not pour a hot phase into the bottle. Allow the product to cool down; a sudden temperature change may crack the glass.
- Water-based products must be preserved just as they would be in any other container. Glass protects the contents from light, not from microbial contamination.
Amber glass limits light penetration but does not prevent oxidation by air. For essential oils and oils prone to oxidation, a tightly secured closure and as little air as possible in the bottle are equally important.
