White Glass Bottle, Lotion Pump with Black Overcap, 30 ml

Glass pharmaceutical bottle, white, lotion pump with black top, 30 ml

A bottle made of white glass with a nominal volume of 30 ml and a fitted lotion pump with a black top. The set is designed for thicker cosmetic products that are dispensed in small doses without dipping your fingers into the packaging: face and eye creams, thicker serums, body and face lotions, gel creams or BB creams. White glass is opaque and lets less light through to the contents than clear glass, which you will appreciate with emulsions containing oils and light-sensitive active ingredients. The contents cannot be seen from the outside, and the packaging looks uniform even with different shades of filling.

Both the bottle and the pump are suitable for contact with cosmetic products, and the declaration of conformity is available with the product. The set as a whole is not approved for contact with food.

What the set includes

• Glass pharmaceutical bottle – a shape with a straight body and a narrower neck, in white glass. “Pharmaceutical bottle” refers to the shape of the bottle, which is common in cosmetics for creams and serums.
• Lotion pump – a polypropylene (PP) pump with a tube that draws the contents up from the bottom. One press dispenses approximately 0.14 ml, which corresponds to a dose of eye cream or a small dose of face cream. For a larger amount, press several times.

What it is suitable for

A pump with a tube works best with medium-thickness emulsions that can be drawn up and hold their shape once dispensed: light to medium-thick creams, lotions, gel creams and thicker serums. The pump cannot draw up very thick balms, butters and anhydrous pastes, or it becomes clogged by them over time. With liquid contents (toners, hydrolates, clear oils) the pump does work, but the dose is less precise and some of the contents may drip after pressing. A dropper or a fine mist sprayer is more suitable for such fillings.

The 30 ml volume suits products that are used up within a few weeks: eye cream, décolleté cream, hand cream for your handbag, a serum for targeted skin treatment. It is also suitable for samples and test batches before production in larger packaging.

Nominal volume and total volume

The nominal volume is the amount the packaging is designed for under normal filling. The total brimful volume is the physical volume of the bottle up to the neck, and you will find it in the parameters. The difference between them provides a reserve for the tube and the pump mechanism and for the expansion of the contents with temperature changes. Fill up to the nominal volume, not to the brim. If the bottle is overfilled, the contents are pushed out through the neck when the pump is screwed on, and the thread seals less well.

Preparation and filling

Before the first filling, wash the bottle and the pump, disinfect them with isopropyl alcohol (IPA) or ethanol and leave them to dry completely. Moisture inside would get into the finished emulsion.

If the tube of the pump reaches the bottom and bends, shorten it with a straight cut so that it ends just above the bottom. A bent tube draws up poorly and part of the contents remains unused. After screwing on the pump, prime it by pressing it several times until it starts to dispense cream. The first presses only push air out of the mechanism.

Good to know

• Preservation – compared with a jar, the pump limits contact of the contents with fingers and air, but it does not replace a preservative in products with a water phase. This is not an airless system; air enters the bottle with every press.
• Residue at the bottom – the tube does not draw up absolutely everything. A small amount of cream remains below its end, so take this into account with smaller batches.
• Essential oils and solvents – the pump is declared for contact with common cosmetic preparations. For formulations with a higher proportion of essential oils or with solvents, we recommend checking how the pump behaves with the specific formulation.
• Reuse – after washing and disinfection, the bottle can be filled again. Rinse the pump by pumping warm water through it and leave it to dry. If the mechanism becomes clogged with dried cream, it dispenses unevenly and it is better to replace it.
• Another closure – you will find closures with the same neck type (stated in the parameters of the bottle) and ready-made combinations in the Handymade range. If you make your own combination, we recommend checking the tightness and dispensing.
• Recycling – glass and the plastic pump are sorted separately. Take the set apart before disposal.
