Clear Glass Bottle, Lotion Pump, 50 ml

A clear glass bottle with a capacity of 50 ml and a black lotion pump make up a ready-to-fill set for face creams, body lotions, fluid emulsions and serums. The contents are dispensed by pressing the pump, without opening the packaging. You do not scoop the product out of a jar with your fingers, so fewer impurities get into it than with an open container. The clear glass shows the colour and consistency of the contents, which is useful for products where appearance is part of the result, for example tinted emulsions or gel serums with a pearlescent effect.

The set is declared as suitable for contact with cosmetic products. The glass bottle itself also has a certificate for direct food contact, but the pump does not, so the set as a whole is intended for cosmetics. You will find the declarations of conformity on the product page.

What the set is suitable for

The lotion pump is designed for contents that can be drawn up through the dip tube and pushed through the pump. It works best with medium and lower viscosity:

• Face creams and fluids – light O/W emulsions for day and night, dispensed in small amounts.
• Serums and gel serums – water-based or gel systems with hyaluronic acid, niacinamide or peptides, where an exact dose matters.
• Body lotions and hand lotions – in a 50 ml size as a travel pack or sample.
• Oil serums and oil blends – the pump measures out a dose better than tilting the bottle.

Thick creams, balms and butters with a high proportion of solid ingredients are drawn through the pump with difficulty or not at all. A jar is more suitable for such products. For creams that are borderline, fill one bottle and check whether the pump delivers the whole dose without air gaps.

How the pump works

The pump draws the contents up from the bottom of the bottle through a dip tube and, when pressed, pushes the measured amount out through the nozzle. After the first filling, press the pump several times to prime it until the tube fills and the pump starts to deliver. If the tube is too long for the bottle, shorten it with a sharp knife so that it ends just above the bottom. Almost all of the contents can then be used.

With every press, air is drawn into the bottle to replace the dispensed volume. Emulsions and serums in this packaging therefore need effective preservation, just as in any other open system. For products containing antioxidants and easily oxidised oils, bear in mind that once opened, the contents are in contact with air.

Filling and capacity

The bottle is designed for a nominal volume of 50 ml. The total brimful capacity is larger and you will find it in the parameters. The difference is a reserve for the dip tube, the pump thread and the expansion of the contents when the temperature changes. Fill only up to the nominal volume. An overfilled bottle will overflow when the pump is screwed on, and the contents will get into the thread, where they dry over time and make opening more difficult.

Fill emulsions only once they have cooled to room temperature. Glass does not tolerate sudden temperature changes well. In addition, a warm emulsion changes its volume and viscosity as it cools, so you would not be able to judge correctly how well the pump dispenses it.

Good to know

Before the first filling, wash the bottle and the pump, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in the tube would dilute the first doses. In anhydrous oil products, it would also introduce water into a system without preservation.

The bottle can be reused, as the glass can be washed and disinfected thoroughly. The pump has an internal mechanism that is harder to clean of emulsion residues. When refilling, rinse it with warm water containing a small amount of surfactant, pump clean water through it several times and leave it to dry. For products with a high proportion of essential oils or alcohol, check whether the plastic parts of the pump change their properties after several weeks and whether the contents leak.

The glass bottle can also be combined with other closures with the same neck type from the Handymade range. When making your own combination, check the tightness, the dispensing and the behaviour of the packaging with your specific formulation.

For recycling, glass belongs with glass and the polypropylene pump belongs with plastics, so separate them before disposal.
