White plastic bottle, 24/410, black fine mist sprayer, 100 ml

The white plastic 100 ml bottle with a black 24/410 fine mist sprayer is supplied as a ready-to-fill set. It suits thin water-based products applied as a mist: facial and body toners, hydrosols, refreshing skin sprays and hair waters. The white bottle hides the contents, so less light reaches them than through clear packaging. PET is lightweight and does not break if dropped. The ribbed collar of the sprayer makes the closure easier to tighten and loosen.

The set is declared suitable for contact with cosmetic products. Only the bottle has a certificate for direct food contact; the sprayer does not, so the set as a whole is intended for cosmetics.

How the set dispenses

The sprayer draws the contents up through a tube from the bottom and breaks them into fine droplets when the head is pressed. One press releases approximately 0.14 ml; the value is indicative. The product is therefore applied in small doses and covers a larger area evenly, without collecting into drops on the skin.

Only liquids with a viscosity close to water belong in the sprayer. Thicker emulsions, gels or oils put a strain on the valve: the product then comes out as a stream, or the sprayer stops drawing up the liquid. For formulations with solubilised essential oils or a higher proportion of alcohol, we recommend testing on a single unit whether the nozzle clogs over time and whether the plastic changes.

Nominal volume and filling headroom

The nominal volume is the amount the bottle is designed for under normal filling, here 100 ml. The physical volume up to the neck is larger. The difference provides headroom for the tube and body of the sprayer, which push part of the liquid level upwards once screwed on, and for the expansion of the liquid with changes in temperature. The bottle should therefore be filled to the nominal volume, not to the brim. Otherwise the contents will overflow through the neck when the closure is tightened.

Suitable for products such as

• Facial and body toners – thin water-based solutions with active ingredients that are meant to reach the skin in a thin layer.
• Hydrosols – on their own or in blends; spraying is the usual way of applying them.
• Hair waters and sprays – products without thickeners to refresh the lengths or the scalp.
• Room and fabric sprays – scented water and alcohol blends; with a higher alcohol content, check how the sprayer behaves.
• Travel and sample sizes – the 100 ml volume also suits travelling.

Good to know

Before first filling, wash the bottle and the sprayer, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Flush the tube and valve with a few presses using clean water or alcohol. Water residues inside would dilute the product and, in a poorly preserved formulation, encourage the growth of microorganisms.

The set withstands repeated use. After emptying, take it apart, rinse it and disinfect it again when changing the product. A sprayer that has held a fragranced or coloured product for a longer time may not come completely clean. When changing the fragrance, it is safer to fit a new one.

The bottle has a 24/410 neck. You can find other closures with the same neck type, as well as ready-made combinations, in the Handymade range. If you build your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

For disposal, separate the sprayer from the bottle. The bottle is made of PET and the sprayer of polypropylene; each material is recycled separately.
