Green Glass Bottle with Roll-On, 100 ml

The green glass roll-on bottle 100 ml is a complete set ready for direct filling: a glass medicine bottle with an 18/410 neck finish, a roller ball insert with a metal ball and a black plastic cap. The contents are applied by rolling the ball over the skin, without dripping and without your fingers touching the contents. It is suitable above all for oil blends with essential oils, massage and aromatherapy oils, perfume oils or roll-on deodorants.

The set is declared suitable for contact with cosmetic products. You can find the declaration of conformity on the product page. It is not intended for contact with food.

How the set works

After filling, the roller ball insert is placed on the neck of the bottle and pressed in firmly, and the cap is then screwed onto the 18/410 thread. The steel ball sits in a clear polypropylene insert. When rolled, it turns and transfers a thin layer of the contents onto the skin. Dispensing is even and economical, which you will appreciate with blends containing a higher proportion of essential oils, where only a small amount is applied.

The 100 ml volume is a larger format among roll-on packaging. It suits massage oils for larger areas, deodorants or blends that are used daily and where a 10 ml bottle would quickly be empty. For concentrated perfume oils or more expensive blends, consider whether the contents will be used up within a reasonable time.

What it is suitable for

• Oil blends with essential oils – pulse point, sleep or relaxation blends in a carrier oil. The ball applies exactly as much as is needed.
• Massage and aromatherapy oils – a larger volume and rolling over a larger area, for example the neck, shoulders or feet.
• Roll-on deodorants – both water-based and alcohol-based formulations, as long as they have a viscosity that lets the ball roll freely.
• Perfume oils and alcohol-based perfumes – small doses on pulse points without spilling and without your fingers touching the contents.

Volume and filling

The nominal volume is the volume for which the packaging is intended with normal filling. The brimful capacity is the physical volume up to the neck and can be found in the parameters. The difference between them is a reserve for the roller ball insert, which takes up part of the space in the neck once inserted, and for the expansion of the contents when the temperature changes. Fill the bottle up to the nominal volume, not to the brim. An overfilled bottle will push the contents out when the insert is pressed in, and the thread may become soiled.

Good to know

Before the first filling, wash the bottle, the roller ball insert and the cap, disinfect them with isopropyl alcohol or ethanol and let them dry completely. With an oil filling, moisture in the ball insert would show up as cloudiness, and in water-based formulations it increases the risk of microbial contamination.

Do not fill the glass with hot contents. A sudden change in temperature can damage it, and the polypropylene insert is harder to fit into a warm neck. Let the filling cool to room temperature, then fill.

Both the cap and the ball insert are made of polypropylene. For blends with a high proportion of essential oils or with solvents, we recommend checking how the insert behaves with your specific formulation, as well as its tightness during transport and storage lying on its side.

The bottle can be reused. Wash out oil residues with warm water and washing-up liquid, rinse with ethanol and dry. When sorting waste, separate the glass from the plastic cap and the roller ball insert.
