Blue Glass Bottle, Lotion Pump, 100 ml

Glass bottle, blue, lotion pump, 100 ml combines a blue glass medicine bottle with a nominal volume of 100 ml and a black plastic lotion pump with a clear overcap. The blue glass limits the amount of light reaching the contents, which suits formulations with light-sensitive vegetable oils, vitamins or extracts. The pump dispenses the contents in small doses, so you never need to reach into the bottle.

The set is most often used for light to medium-thick creams, face and body lotions, fluids, thicker serums and hand creams. A volume of 100 ml is enough for a daily face cream lasting several months or for a smaller batch of body lotion. Glass does not react with common cosmetic ingredients and can be refilled after washing, while the pump is made of polypropylene (PP). Both components are declared suitable for contact with cosmetic products; you will find the declarations of conformity on the product page.

What the set is suitable for

• Face and body creams – one press of the pump dispenses a portion that spreads easily over the face or hands, with no need to guess the amount.
• Lotions and fluids – thinner emulsions are drawn up smoothly through the dip tube and do not spill when the bottle is tilted.
• Thicker serums and gel creams – water-based and emulsion serums with higher viscosity, where a dropper would not be enough.
• Formulations with sensitive active ingredients – a closed pump limits contact between the contents and the surroundings between uses.
• Small batches for sale and gifts – the bottle is classed as retail packaging, so it also suits finished products intended for sale.

Filling and dispensing

The nominal volume is the volume the packaging is designed for under normal filling. The brimful volume given in the parameters is the physical volume of the bottle up to the neck. The difference between them leaves room for the dip tube and the pump body and for the contents to expand when the temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim. If you fill it further, the dip tube will push the contents out through the neck when you screw on the pump.

One press dispenses approximately 0.12 ml. For a face cream one or two doses are usually enough, for body lotion more, depending on the area treated. This figure also helps when planning a formulation with more expensive active ingredients, because you can estimate how much of the active ingredient reaches the skin with each use.

After screwing on the pump, press it several times until the dip tube fills and the contents start to come out. Thick creams, balms or formulations with solid particles (scrubs, crystalline sugar, salt) are hard for the pump to draw up or can clog it. With a thicker emulsion, we recommend testing the dispensing on a small amount first and adjusting the viscosity of the formulation if necessary.

Good to know

A pump with a dip tube draws the contents from the bottom, and with every press air enters the bottle to replace the volume used. Water-based and emulsion formulations therefore need a preservative, just as in an ordinary jar. The advantage over a jar is that fingers do not touch the contents, so microbial load during use is lower.

Before the first filling, wash the bottle in warm water, disinfect it with isopropyl alcohol or ethanol and leave it to dry completely upside down. Rinse the pump in warm water, pump clean water through it several times and leave it to dry. The glass can be reused; with the pump, it depends on how thoroughly it can be cleaned of the previous formulation. When you change the formulation or after longer use, it is more sensible to replace the pump with a new one.

Polypropylene resists common cosmetic ingredients. For formulations with a high proportion of essential oils, alcohol or solvents, we recommend testing how the pump behaves on a small amount. The set is not declared for contact with food; it is intended for cosmetics.

The bottle has a neck with the thread given in the parameters. You will find other closures with the same neck type and ready-made combinations in the Handymade range. If you make your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

When transporting finished products, put the overcap on the pump head and transport the bottles upright. At the end of their life, the glass belongs in glass recycling and the pump in plastics; separate them before disposal.
