Amber Glass Bottle, Straight Top, 24 mm, Black Mat Plastic Cap, 100 ml

The glass bottle with a flat top and a matte black cap is a ready-made 100 ml set: fill it, close it and use it without searching for a suitable closure. The amber glass bottle dims light and thus helps protect contents that quickly lose quality in the light: plant and essential oils, oil serums, tinctures, alcohol extracts or facial toners. The screw-on plastic cap closes the bottle with a simple tightening, so the set is suited to products dosed by pouring or measuring, not by dropping or spraying.

The whole set is declared as suitable for contact with cosmetic products. The glass bottle alone holds certification for direct contact with food; the set as a whole is intended for cosmetics.

Why choose this set

• Protection from light – amber glass transmits less light than clear glass, which slows the oxidation of oils and the fading of coloured extracts. For products with essential or unsaturated plant oils, this is a practical advantage.
• Glass takes on no scents or dyes – after washing, the bottle can be used for a different content without any smell of the previous product lingering in it. This sets it apart from plastic bottles, which gradually "absorb" essential oils.
• Ready-made combination – the cap with a 24/410 thread matches the bottle neck, so there is no need to check whether the closure fits. The matte black colour of the cap looks understated on amber glass.
• Practical volume – 100 ml corresponds to a standard pack of massage or facial oil, a toner or a larger pack of serum.

What the set is suited for

It works best with liquid products dosed into the palm or poured out: massage and body oils, oil serums for skin and hair, blends of carrier oils with essential oils, herbal tinctures, alcohol-based lotions and toners, oil herbal extracts. Thanks to the glass, it is also suitable for contents with a higher proportion of alcohol, which could strain plastic packaging over the long term.

It is less suitable for thick creams and butters, which are hard to remove through the narrower neck, and for products that need precise drop-by-drop dosing or spraying. For those, the Handymade range offers ready-made combinations of the same bottle with other closures that share the same neck type.

Filling and volume

With this packaging you will come across two volume figures. The nominal volume is the volume the bottle is designed for under normal filling, i.e. 100 ml. The total brimful volume is the physical volume up to the neck and is somewhat larger. The difference between them is a reserve for the cap and for the expansion of the contents as the temperature changes. The bottle is filled to the nominal volume, not to the brim. When overfilled, the packaging pushes part of the contents into the thread as the cap is tightened and may leak when warmed.

Good to know

Glass and heat. The bottle withstands warm filling, but not a sudden change in temperature. Do not pour hot contents into cold glass and do not place a filled bottle directly on a hot surface. Let blends prepared hot cool to a lukewarm temperature before filling.

Cap and essential oils. The cap is made of polypropylene, which is resistant to both plant oils and alcohol. For products with a high proportion of essential oils, we recommend checking the seal on the first piece with the specific recipe before you fill the whole batch.

Tightening. The cap only needs to be tightened by hand. Excessive force when screwing it on will not improve the seal but can damage the cap thread.

Label. The straight cylindrical body of the bottle provides a continuous surface for a label without any fold. You will find the bottle dimensions in the product parameters.

Reuse and recycling. The bottle can be used again after thorough washing and disinfection. When discarded, the glass and the plastic cap are separated and sorted individually by material.
