Glass bottle, glossy black, white pump dispenser, 10 ml

This black glossy glass bottle with a nominal volume of 10 ml and a white lotion pump is intended for small packs of creams, serums and emulsions that are taken out in doses, without dipping fingers into the contents. The opaque black glass does not let light through to the contents, so it is also suitable for formulations with sensitive ingredients, for example vitamin C, retinol or oils prone to oxidation. The pump dispenses approximately the same amount with each press, which is useful for eye creams, concentrated serums and anywhere that every dose of a more expensive active ingredient matters.

The set is declared as suitable for contact with cosmetics. Only the glass bottle has a separate certificate for direct food contact; the pump does not, so the set as a whole is intended for cosmetic products.

What it is suitable for

• Eye creams and lip area creams – the small volume matches the consumption when applying a thin layer, and the pump always measures out a similar amount.
• Serums and light emulsions – a thicker serum or a creamy texture is taken out cleanly with the pump, without running down the neck and without opening the bottle.
• Samples and travel packs – ten millilitres is enough for several weeks of trying a new formulation or for a stay away from home.
• Concentrated products with a higher content of active ingredients – they are applied to targeted spots in small amounts, so a larger bottle would stay unfinished for a long time.

Filling and dispensing

The nominal volume is the volume the bottle is designed for during normal filling. The total brimful volume given in the parameters is the physical volume up to the neck. The difference provides a reserve for the tube and the pump body and for the expansion of the contents when the temperature changes. For this reason, fill only up to the nominal volume. If the bottle is filled to the brim, part of the contents will overflow through the neck when the pump is screwed on.

The narrow neck calls for filling with a small funnel, a syringe or a spatula. After screwing it on, prime the pump by pressing it several times until it starts to dispense the contents. One press corresponds to approximately 0.14 ml.

Good to know

• Preparation before first filling – wash the bottle, disinfect it with ethanol or isopropyl alcohol and let it dry completely. It is enough to rinse the pump with clean water and let it dry, so that water residues do not dilute the first doses.
• Hot filling – fill the emulsion only after it has cooled. In a warm fill, condensation forms under the pump and the contents change volume as they cool, which can cause air to get into the pump.
• Air access – a pump with a tube is not an airless system; air is drawn into the bottle with every press. Water-based formulations therefore need preservation, just as in any other open packaging.
• Checking the fill level – you cannot see through black glass how much of the contents remains. With 10 ml this is usually not a problem; for larger batches, a filling date on the packaging helps.
• Reuse – the glass bottle can be refilled after washing and disinfection. The pump has an internal mechanism and a tube that are hard to clean. When you change the formulation, it is safer to replace the pump with a new one.
• Other closures – the bottle can also be used with other closures that have the same neck type given in the parameters. For your own combination, we recommend checking the tightness and dispensing with your specific formulation.
• Recycling – after use, separate the pump from the bottle. The glass belongs with glass and the polypropylene pump with plastics.
