White Glass Bottle, Black Cap, 100 ml

The white glass medicine bottle with a black cap is intended for filling cosmetic products that do not need a pump: face and body oils, oil serums, hydrosols and pouring toners, finished products and intermediates during production. White glass hides the contents and limits light exposure, which matters for oils and active ingredients that lose quality faster in light. The narrow neck with an 18/410 neck finish lets you pour the contents in small amounts without spilling. With a nominal volume of 100 ml, the medicine bottle suits products that are used up within a few weeks, as well as larger samples.

Bottle and cap together

The cap is a plain screw cap with no dispensing opening. Its body is made of polypropylene, and inside it has a foam polyethylene (EPE) liner that sits on the rim of the neck and seals the joint. It is closed by tightening by hand. A black cap on white glass gives the bottle a simple look.

Glass does not react with common cosmetic raw materials and does not absorb odours, so the medicine bottle can be washed after use and filled with another product. For the cap, the condition of the liner is decisive. If it is compressed or cracked after repeated use, the joint stops sealing and it is better to replace the cap.

Nominal volume and brimful capacity

The nominal volume of 100 ml is the amount the medicine bottle is designed for in normal filling. The brimful capacity is the physical volume up to the top of the neck, and you will find it in the parameters. The difference between the two leaves room for the cap and for the contents to expand with changes in temperature. Fill to the nominal volume, not to the brim, otherwise the contents are pushed onto the thread when the bottle is closed and the cap then sticks or does not seal.

Suitable for products such as

• Face and body oils – white glass limits light exposure, and the contents pour from the narrow neck into the palm in drops or small amounts.
• Oil serums and blends with essential oils – glass is resistant to them. With a high proportion of essential oils, we recommend checking how the cap liner behaves with your specific blend.
• Hydrosols and toners – for pouring onto a cotton pad or into the palm, with no need for a sprayer.
• Alcohol tinctures and extracts for cosmetic purposes – glass does not affect the alcohol, and the opaque wall also hides coloured contents.
• Samples, intermediates and test batches – the 100 ml volume fills quickly and is used up just as quickly, and you can then use the bottle again.

Good to know

Before the first filling, wash the bottle and the cap, rinse them and disinfect them with isopropyl alcohol or ethanol. Let them dry completely, especially the cap liner, in which residual water stays longer than on glass.

The set is declared suitable for contact with cosmetic products. You will find closures with the same 18/410 neck finish and ready-made bottle and closure combinations in the Handymade range. If you combine them yourself, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

At the end of its life, the glass belongs in glass waste and the cap in plastics, so separate them before disposal.
