Plastic bottles of spray is generally not pressurized, that is, no pressure difference between the bottle and the bottle, the spray is produced by the pump head pressure
No pressure difference spray, mist spray range is small, fog is coarse
There is pressure difference spray, generally use aluminum cans, spray is pressed by air pressure, and if the nozzle quality is very good, the fog will be very fine, more conducive to skin absorption
The quality of plastic bottles is uneven, and the better the material is, the closer the structure is, the less it dissolves with the solution in the bottle
So, still depends on the material of bottle body
Inferior plastic bottles, bottles will dissolve into the bottle solution, detrimental to the skin
