White Plastic Bottle, Glossy Silver White Pump, 10 ml

This white plastic pharmaceutical bottle with a capacity of 10 ml and a glossy white and silver pump is a set for small quantities of serums, fluids and light emulsions that are dispensed in doses without touching them with your fingers. The white opaque PET hides the contents and limits light exposure. The bottle is lightweight and unbreakable, so it suits samples, travel packs or testing a formulation in a small batch. The pump with an 18/415 neck finish fits the G18x3 neck of the bottle, and the set as a whole is declared suitable for contact with cosmetics.

What it is suitable for

• Face and eye serums – the liquid consistency passes through the dip tube without resistance, and one dose corresponds to the amount needed for a single application around the eyes or on the face.
• Light emulsions and fluids – thin O/W creams and milks that the pump dispenses without problems and that spread quickly on the skin.
• Oil serums and blends of vegetable oils – dispensing in doses limits the contact of the oil with air and with hands, compared with an open bottle.
• Samples – the customer tries the product in the same way as they will use it from the full-size pack.
• Travel packs – a small volume and plastic that will not crack in a cosmetic bag.

Using the pump

One press of the pump releases approximately 0.14 ml of the contents. With a standard serum, this corresponds to the amount for a single application on the face or around the eyes. With oils, one dose is often enough, and with fluids two to three. After filling and screwing on the pump, prime it by pressing it several times until the dip tube and the head fill and the contents start to come out. Proceed in the same way after a longer break in use.

A mechanical pump with a dip tube works with liquid and slightly viscous formulations. A thick cream or balm will not be drawn up through the tube. Emulsions with solid particles, for example scrub particles, may block the valve. With very thin aqueous solutions, for example toners, it is worth checking that the dose does not drip from the head after pressing. We recommend testing how the pump behaves with your specific formulation on one piece before filling an entire batch.

Nominal volume and filling

The nominal volume is the amount the pharmaceutical bottle is designed for with standard filling. The physical volume up to the neck is larger. The difference provides a reserve for the dip tube and the lower part of the pump, which take up space in the bottle once screwed on, and for the expansion of the contents with temperature changes. Fill up to the nominal volume, not to the brim, otherwise the contents will overflow through the neck when the pump is fitted.

Good to know

Before the first filling, wash the bottle, disinfect it with isopropyl alcohol or ethanol and let it dry completely. The pump is rinsed by immersing the dip tube in the disinfecting solution, pumping the solution through several times and then pumping air through in the same way until nothing comes out of the head. When reusing the bottle, repeat the procedure and check that the pump dispenses evenly after rinsing.

PET withstands vegetable oils as well as aqueous and emulsion formulations. For formulations with a high proportion of essential oils or with solvents, we recommend checking how the material behaves on a test piece, as aggressive ingredients may soften or discolour the plastic. Let the contents cool to room temperature before filling.

The bottle is made of PET and belongs in sorted plastic waste. The pump combines polypropylene with aluminium and is unscrewed from the bottle before disposal. Closures with the same neck type, as well as ready-made bottle and closure combinations, can be found in the Handymade range. If you combine parts yourself, we recommend checking the tightness and dispensing with your specific formulation.
