White Airless Jar with Silver Lining, 50 ml

Airless jar 50 ml with a pump dispenses cream without drawing air into the container with each use. The contents are pushed upward by a piston at the bottom; each press of the pump delivers the same small dose, and the remainder stays sealed. It is suitable for face and eye creams, thicker serums and emulsions with sensitive active ingredients, where it matters that the product does not come into contact with fingers during use and oxidises as little as possible.

The body of the jar is white, the cap with the pump is complemented by a silver trim. The combination of PP and PMMA gives the container a glass-like shine while remaining lightweight and shatterproof, so it can withstand shipping in a parcel. The complete set is declared as suitable for contact with cosmetics.

How an airless jar works

A regular jar fills with air every time it is opened and the cream is scooped out with fingers. Inside an airless jar there is a movable piston beneath the contents; when the pump is pressed, it moves slightly upward and pushes a dose to the top of the cap. No air returns inside, the contents remain sealed and protected at all times. The oil phase and active ingredients oxidise more slowly, the risk of microbial contamination is lower, and the container empties almost completely — the piston travels all the way to the top wall.

When the cap is attached, the pump is empty. A few dry presses will fill it, after which it will start dispensing evenly.

What it is suitable for

• Creams with sensitive active ingredients – vitamin C, retinol, peptides and unstable plant extracts will retain their efficacy longer in a closed system without air than in an open jar.
• Eye and face creams – a dose of 0.4 ml per press corresponds to typical use on the face or eye area; the customer does not over-apply.
• Emulsions with an oil phase prone to yellowing – without air exposure, the scent and colour of unrefined oils and butters change more slowly.
• Natural cosmetics with a milder preservation system – a container that is not touched by fingers reduces the introduction of microorganisms. It does not replace the preservative, however; a water-based formulation needs one even in an airless container.
• Samples and trial batches – the 50 ml volume is suitable for testing a new formulation with customers or in a salon.

The pump handles creams and thicker emulsions that hold their shape but can be spread. Very thin liquids do not belong in an airless jar — the piston does not reliably separate them and they may leak. Solid balms and butters cannot be pumped out either. We recommend testing the behaviour of a specific formulation on a single unit before filling an entire batch.

Filling and volume

Nominal volume is the amount the jar is designed for under standard filling. Total volume to the rim is the physical capacity right up to the neck and is slightly larger. The difference provides a margin for the cap with the pump and for the movement of the contents. The jar is therefore filled to the nominal volume, not to the rim; both values are listed in the parameters.

Before filling, unscrew the cap and make sure the piston is in the bottom position. Add the cream slowly, preferably with a spatula or filling bag from the centre, to prevent air bubbles from becoming trapped underneath. Let a hot emulsion cool down first. Warm contents shrink as they cool and leave air in the container, which the pump then pushes out instead of the cream.

Good to know

• Preparation before first filling – wash the jar and cap, disinfect with isopropyl alcohol or ethanol and allow to dry completely. Moisture beneath the piston would get into the cream.
• Material and resistance – polypropylene tolerates standard cosmetic emulsions, oils and water phases. For formulations with a high proportion of alcohol, essential oils or solvents, we recommend checking the container's behaviour over time.
• Labelling – a band label is applied to the body and a round label to the cap. The dimensions of both the jar and the cap are listed in the parameters.
• Reuse – after emptying, the piston is in the upper position. We recommend a new jar for a new batch. If you wish to reuse it, clean it thoroughly, push the piston back down and verify that it moves without sticking and the cap seals properly.
• Recycling – dispose of the container as plastic.
