Plastic bottle, white, 18/410, black fine mist sprayer, 100 ml

White plastic bottle with black spray pump, 100 ml

Ready-made set of bottle and spray pump for thin liquid preparations applied by spraying – facial tonics, hydrolats, hair and body mists, fabric and air fresheners, or disinfectant solutions. The white wall made of PET reduces light exposure to the contents. Plastic is lightweight and unbreakable, making the packaging suitable for travel, a handbag or a desk, where glass would be unnecessarily heavy and fragile. The 100 ml volume is sufficient for regular use while being depleted before the contents lose their freshness.

The set as a whole is declared as suitable for contact with cosmetics. The bottle alone holds a certificate for direct food contact; the spray pump does not. The set is therefore intended for cosmetic and technical use, not for food liquids.

How the set works

• Bottle – a lightweight white PET bottle with a standard 18/410 neck, which won't break when dropped and won't deform under normal use. The white colour conceals the contents, which is appreciated for light-sensitive products.
• Spray pump – a black plastic spray pump with a transparent dip tube sized to match the bottle height. The contents can thus be dispensed almost to the last drop. One press releases approximately 0.14 ml of fine mist – a dose suitable for applying tonic to the face or a mist to hair without over-wetting.
• Appearance – the combination of white bottle and black spray pump looks clean and works well with both colour and plain labels.

Nominal and total volume

For every bottle, a distinction is made between nominal volume and total volume to the brim. Nominal volume is the quantity the packaging is designed for during regular filling. Total volume is the physical capacity up to the neck. The difference between them is the allowance for the spray pump dip tube, which displaces part of the volume when fitted, and for the expansion of the contents with temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim – otherwise the contents will spill over the neck when fitting the spray pump.

What is suitable for the spray bottle

The spray pump works reliably with contents that have viscosity close to water. These include:

• Facial tonics and hydrolats – fine mist spreads evenly across the face, no need to apply with hands.
• Hair and body mists – aqueous or alcoholic solutions with solubilised essential oils or fragrance compositions.
• Air fresheners and fabric sprays – alcoholic or aqueous bases with fragrance.
• Disinfectant solutions for hands and work surfaces – alcoholic solutions of common concentrations.
• Technical use in the workshop – for example, spraying alcohol onto the surface of cold-process soap against soda ash, or moistening powder pigments.

Conversely, thick emulsions, gels and oils with higher viscosity are not suitable. The spray pump either cannot draw them in, or releases them as a stream rather than a mist and eventually clogs. Equally unsuitable are preparations with undissolved particles (scrubs, suspensions) that block the nozzle.

What is good to know before filling

• Preparing the packaging – before the first fill, rinse the bottle, disinfect it with isopropyl alcohol or ethanol and allow to dry completely. Rinse the spray pump with clean water and pump several times to remove any manufacturing residues.
• Priming the spray pump – after fitting onto a full bottle, several empty presses are needed before the dip tube and pump fill with contents. This is normal, not a defect.
• Leak-tightness during transport – the spray pump is not a hermetic seal like a cap. When transported on its side or with large temperature fluctuations, a small amount of contents may leak. When shipping to customers, transport the bottle upright, or test the seal in advance.
• Heat – PET is not designed for filling hot contents. Allow the finished product to cool to room temperature before filling, otherwise the bottle may deform.
• Repeated use – both the bottle and the spray pump can be used multiple times. Between refills, clean the packaging in the same way as before the first fill. When switching to a different type of contents (from alcoholic to aqueous and vice versa), it is safer to use a new spray pump.
• Preservation of contents – the spray pump limits contact of the contents with fingers, but aqueous preparations still require a preservative. The packaging itself does not protect them against microbial spoilage.
• Recycling – the bottle is PET, the spray pump is made of polypropylene and consists of several parts. Before disposal, unscrew the spray pump from the bottle and sort both parts as plastic.
