Clear Frosted Glass Bottle with Roll-On, 15 ml

The 15 ml frosted glass roll-on bottle is used for applying oil-based perfumes, aromatherapy blends and light oil serums directly onto the skin. The set consists of a glass bottle with an 18/410 neck, a holder with a steel roller ball and a black plastic cap. After filling, simply press the ball holder into the neck, screw on the cap and the product is ready for sale or for your own use.

The frosted surface of the glass dampens direct light and the contents only show through the wall, which suits blends with essential oils better than clear glass. The small volume matches the amount that is used up within a few weeks when applied to specific spots such as the wrists, temples or the eye area, so oils do not sit for too long in a half-empty bottle. The set is declared suitable for contact with cosmetics; you will find the declaration of conformity with the product.

What the roll-on bottle is suited for

• Oil-based perfumes – the ball applies a thin layer exactly where the fragrance is meant to last, without spraying it into the surroundings.
• Aromatherapy blends – essential oils diluted in a carrier oil for the temples, nape or wrists. The roll-on is also a common format for travel blends.
• Oil serum for the eye area – a small amount is spread without your fingers touching the contents, and the steel ball feels cooling on the skin.
• Oil for lips and cuticles – free-flowing oils and low-viscosity oleogels are applied directly where they are needed.

How the set works

After filling, the ball holder is pressed into the bottle neck, where it is held by its shape alone, without any glue. The ball rotates on contact with the skin and delivers a thin film of the contents. The cap screws onto the bottle thread, covers the whole ball and prevents drying out and leaking when carried in a handbag.

Liquids with low to medium viscosity are suitable for a roll-on, that is vegetable oils, fragrance oils and light oil serums. Thick balms and butters will not move the ball, while very thin water-based solutions may seep around the ball. Test the behaviour of your particular formulation on one filled piece before filling a larger batch.

Nominal and brimful volume

The nominal volume of 15 ml is the amount the bottle is designed for in normal filling. The brimful volume is the physical volume up to the rim of the neck and can be found in the parameters. The difference between the two values leaves room for the ball holder, which takes up part of the space once pressed into the neck, and for the expansion of the contents when the temperature changes. Fill to the nominal volume, not to the rim.

Filling and reuse

Before the first filling, the bottle, the ball holder and the cap are washed, disinfected with isopropyl alcohol or ethanol and left to dry completely. Fill the bottle only once the contents have cooled down. A hot filling can damage the glass through thermal shock and the ball holder may not sit properly in the neck.

The holder and the cap are made of polypropylene, which withstands common vegetable and fragrance oils. With undiluted essential oils, a high proportion of alcohol or solvents, check whether the holder changes shape or colour over time, as it is in permanent contact with the contents.

Once empty, the ball holder can be pried out of the neck and the set can be reused after washing and disinfection. When reusing, check that the holder fits tightly in the neck and that the ball rotates freely. The glass bottle is sorted as glass, the cap as plastic after separation.

Closures with the same neck type, given in the parameters, and other ready-made combinations of a bottle with a closure can be found in the Handymade range. For your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your particular formulation.
