Clear Airless Bottle with Golden Bottom, 45 ml

The 45 ml airless bottle with a transparent body and gold base is an airless dispensing container for creams, serums and light emulsions that need to stay protected from air from the first to the last pump. The set consists of a bottle with an airless piston system and a gold cap with a pump, so it just needs to be filled and is ready to use. It is particularly suited to formulations with sensitive active ingredients for which a standard jar or a bottle with an open neck are not the best choice.

The transparent body shows the contents and how much product remains. The gold base and cap give the packaging an appearance suitable for gift sets or a small retail series. The set is declared as suitable for contact with cosmetics.

How the airless system works

Unlike a standard pump with a dip tube, the airless bottle has no tube inside and no air gap above the contents. The product sits on a movable piston that moves upward with each press, pushing the contents towards the outlet. No air or fingers enter the bottle during dispensing. The contents are therefore less exposed to oxidation and microbial contamination, and the container can be emptied almost completely, even when held upside down or sideways.

Key benefits

• Protection from air – the contents are not exposed to the surrounding air after opening, which helps preserve the properties of ingredients prone to oxidation, such as vitamin C, retinol or unsaturated vegetable oils.
• Hygienic dispensing – the product is not scooped out with fingers as from a jar, reducing the risk of introducing contaminants into the formulation with everyday use.
• Precise and repeatable dosage – each press releases approximately the same amount, making it easier to dose concentrated serums and eye creams.
• Full use of contents – the piston pushes the product all the way to the outlet, so no unused residue remains on the walls or at the bottom as with a tube bottle.
• Visible contents – the transparent body shows the colour and texture of the product as well as the current level, which is an advantage both for retail and personal use.

Suitable for products such as

• facial serums and emulsions with active ingredients that lose efficacy upon contact with air,
• eye and face creams of light to medium consistency, where small and precise dosing is valued,
• oil serums and gel creams with low dosage, for which 45 ml is a practical size,
• samples and test batches for customers you want to show a product in retail-ready packaging.

Filling and working with the container

Before first filling, it is recommended to wash both the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and allow them to dry completely. Fill from the top with the piston in the lowest position, using a finished and cooled product. Do not pour warm product into the plastic body. SAN plastic is not intended for hot filling and warm contents could create a vacuum in the closed system as they cool.

During filling, avoid air bubbles. Thicker creams are easier to fill using a filling bag or a syringe with a wider nozzle and by gently tapping the bottle on a table so the product settles without cavities. After fitting the cap, the pump needs to be pressed several times until the system is primed and begins to release a dose. The first few empty presses are normal and are not a sign of a defect.

One press releases approximately 0.2 ml of product, which corresponds to a single dose of serum or eye cream.

Good to know

Product consistency determines how the airless system performs. Creams, gel creams, emulsions and medium-viscosity serums dispense best. Very thin, watery products may drip at the outlet or dispense unevenly, while very firm balms may not be drawn up adequately by the pump. With a new formulation it is worth filling one unit and testing for a few days how it dispenses and whether it seals properly.

The transparent body does not protect the contents from light. Formulations with photosensitive ingredients should be stored away from direct sunlight, or an opaque container should be chosen for them. Protection from air and protection from light are two different things, and the airless system addresses only the first.

SAN material is a rigid and clear plastic. For formulations with a high proportion of essential oils, alcohol or solvents, verify compatibility in the finished formulation, as such contents can cloud or etch the plastic over time.

A smaller label also works well on the transparent body, keeping the contents visible. The bottle body is plastic; the cap combines aluminium and plastic, so separate both parts for disposal.
