Gloss Black Glass Bottle, Black Cap, 100 ml

The black glass bottle with a capacity of 100 ml and a black cap is packaging for contents that should not be exposed to light. Opaque black glass protects face and body oils, serums with light-sensitive active ingredients, blends with essential oils, massage oils and alcohol-based toners. The medicine bottle shape with a narrow neck makes it possible to pour out the contents even in small amounts. The glossy black surface of the glass and the equally black cap look like a single piece.

The set is declared as suitable for contact with cosmetic products, and the declaration of conformity is available with the product. Only the glass bottle on its own is certified for direct contact with food. The cap is not, so the set as a whole is intended for cosmetics.

What it is suitable for

• Oils and oil serums – black glass keeps light away from the contents, which helps slow down the oxidation of vegetable oils and of blends with vitamins or essential oils.
• Toners and alcohol-based preparations – glass does not react with alcohol or with water-based blends, and the contents pour straight from the narrow neck.
• Hair and body oils – the medicine bottle sits well in the hand, and you can pour the oil into your palm without an additional pump.
• Retail packaging – the uniform black colour of both the glass and the cap looks neat even without additional decoration.

Volume and filling

Nominal volume is the volume the bottle is designed for in normal filling. Brimful capacity, that is, the physical volume up to the neck, is slightly larger and you can find it in the parameters. The difference between the two values forms a reserve for the closure and for the expansion of the contents when the temperature changes. For this reason, fill the bottle up to the nominal volume and never to the brim, otherwise part of the contents will be pushed out or will leak into the thread when the cap is screwed on.

Cap and closing

The black PP cap with an EPE liner screws onto the 18/410 neck finish. The liner sits against the rim of the neck and seals the contents against leaking during storage and transport. The cap has no dispensing opening. The contents pour straight from the narrow neck of the medicine bottle, which is enough for pouring oils into your palm or for decanting smaller amounts.

If you need to dispense drop by drop or as a spray, the Handymade range includes closures with the same neck type as well as ready-made bottle and closure sets. When you make your own combination, we recommend checking the tightness, the dispensing and the behaviour of the packaging with your specific formulation.

Good to know

Before the first filling, wash the bottle, disinfect it with isopropyl alcohol or ethanol and let it dry completely. Residual water in the bottle would introduce moisture into an anhydrous oil and, without a preservative, also a risk of microbial growth. Treat the cap, including the liner, in the same way.

Glass does not tolerate sudden temperature changes. Let the hot oil phase cool before filling, at least to a temperature at which the bottle can be held in the hand without any problem. Do not pour hot contents into cold glass.

After thorough washing and disinfection, the bottle can be reused. Replace the cap if the liner has become deformed or has stopped sealing. Before disposal, separate the glass from the plastic cap, as each belongs in a different collection container.
