Glass roll-on, amber, black cap, plastic ball, 5 ml

This amber glass roll-on bottle with a volume of 5 ml is designed for small amounts of oil-based perfumes, aromatherapy blends and oils for the skin or lips, which are applied directly to the skin with a roller ball. The set includes an amber glass bottle, a plastic roller ball and a black plastic cap, so once filled the packaging is ready to use. Amber glass reduces the amount of light reaching the contents and helps protect light-sensitive formulations, such as blends with essential oils or carrier oils prone to oxidation.

All three components of the set are declared suitable for contact with cosmetic products, and the declaration of conformity is provided with the product. The set is intended for cosmetics. None of its components is approved for contact with food.

What it is suitable for

The small volume and the roller ball make sense for products that are applied in small amounts and often:

• Oil-based perfumes – fragrance diluted in a carrier oil is applied to the wrists or neck in a thin layer without spilling.
• Aromatherapy blends – essential oils diluted in a carrier oil for the temples, the back of the neck or the wrists.
• Lip oil or cuticle oil – the roller ball spreads a small amount exactly where it is needed.
• Samples and testers – 5 ml is enough to try out a fragrance or an oil blend before making a larger batch.

The roller ball is intended for contents with low to medium viscosity. A thick gel or a solid balm will not roll through it, so a jar or a stick is more suitable for such textures.

Filling and assembly

Before the first filling, the bottle is washed, disinfected with isopropyl alcohol or ethanol and left to dry completely. The roller ball and the cap are treated in the same way. The contents are poured into the empty bottle, and only then is the roller ball pressed into the neck and the cap screwed on. A small syringe or a dropper helps with precise pouring into the narrow neck.

The nominal volume is the amount the packaging is designed for under normal filling. The total brim-full volume is larger, because the bottle needs space for the roller ball inserted in the neck and for the expansion of the contents when the temperature changes. For this reason, fill the bottle up to the nominal volume, not to the brim.

Good to know

Glass tolerates both carrier and essential oils well. The roller ball and the cap are made of polypropylene (PP), which is commonly used for cosmetic closures. Essential oils are filled into a roll-on diluted in a carrier oil. For blends with a high proportion of essential oils or for alcohol-based perfumes, we recommend checking the behaviour of the plastic parts with your specific formulation, and checking the tightness after several days of storage lying on its side.

The roller ball also dispenses water-based or alcohol-based contents, but at low viscosity they leak more easily around the ball. Before making a larger batch, it is advisable to fill a single bottle and test whether the contents leak when carried in a bag.

The bottle can be used repeatedly. The roller ball is carefully prised out of the neck, and all parts are washed and disinfected. For recycling, glass is sorted separately and the plastic parts belong with plastics.
