Press-Button Airless Mechanisms Remove Formula Bulb Contact
A conventional dropper works by squeezing an elastomer bulb that sits in the vapour path of the product and frequently in contact with it. Press-button airless mechanisms draw a measured dose through a sealed piston arrangement instead, so the formulation never touches the bulb material at all. That eliminates the compatibility problem rather than managing it, and it also delivers consistent dose volume that a squeeze bulb never can. Penetration is currently around 9% of units and growing at 11.4%. Cost is the constraint, since the mechanism runs several times a simple bulb assembly.
