Mechanism that sprays liquid in the form of a fine mist. In perfumes, it helps to apply a small amount of product evenly without pouring onto the skin. One press is not a universal measure of volume as pump designs vary between packages. When applying, avoid eyes and follow the manufacturer's instructions, especially when using products intended for skin.
Spraying and the nature of application
The atomizer divides the liquid into small drops and directs them through the nozzle. The method of operation depends on the design of the pump, the opening and the liquid itself. Two bottles can therefore dispense different amounts of perfume with one press. A fine mist covers a different surface than a dense stream, which affects the first impression of the scent. The number of sprays is a useful note from a single bottle test, but not a precise unit for comparing all packages.
When describing the application, it is worth considering the distance of the nozzle and the place of spraying. The same volume spread widely may be perceived differently than when applied pointwise. Do not aim the mist at your face or inhale it immediately after applying it. The cosmetic's instructions determine its proper use.
Meaning and application
One press of different atomizers does not necessarily dispense the same amount of liquid. The design of the pump, the method of pressing and the form of the jet are important. The number of sprays is therefore a practical guide, not a common unit for all bottles.
In practice
When using for the first time, please read the instructions and check the nozzle direction. Spray away from eyes and sources of ignition. If application is irregular, check the tip and how the cap fits; do not forcefully disassemble factory-sealed components.
Do not calculate from the capacity alone that the bottle will last a certain number of days. Without data on pump dosing, this is just an estimate. Do not fix a leak or damage problem by heating the bottle or pouring it into a random container.
