To understand airless pump technology, one must first understand why it is pivotal to the future of lotion dispensing technology. Traditonal dispensing pump containers improperly manages the air-exposure issue. Instead of using the air-replacement principle, as all conventional containers use, airless pump containers use a vacuum mechanism which discards the use of a dip tube. Rather than a dip tube, airless pump containers use a flexible inner bag or piston system. These sealed systems allow for the entire lotion to be used, as the tube does not draw in air, and the formulation is protected from any external airborne contamination.
The primary vacuum pump creates negative pressure and is the core component for airless pump functionality. Each pump also has a piston/diaphragm assembly and a dispensing valve which manages the release of lotion and the vacuum seal around it. High quality seals and gaskets which hold the lotion in place, and maintain the lotion's efficacy also manage the vacuum seal pressure.
Every time you press the pump, it changes the pressure in a sealed compartment. This change in pressure moves the piston, which pushes the lotion through the valve and out the nozzle. When you release the pump, it is as if the valve closes and seals the vacuum so no air gets in. As you continue to pump, the piston rises and gets more lotion. This mechanism does not leave lotion behind in the bottom, and it works efficiently even with thick lotion. The vacuum pressure will always overcome any viscosity challenges.
Airless pump bottles give advantages for both the quality of the lotion and the user experience. Because of the sealed mechanism, no air can get in and the active ingredients, like vitamins and antioxidants, will not oxidize and lose effectiveness. This sealed system also keeps out bacteria and dust, which is a necessity for sensitive and dermatological lotions. Users will also get the benefit of simple, mess-free, and consistent lotion dispensing without the need to tap or shake the bottle. This keeps dosage controlled and allows for easy management of the lotion.
These bottles work for any kind of lotion, be it light lotions or thick body butters. They are mostly used for specialized or premium lotions because that is when you really need to keep the ingredients from spoiling. Their design is leak-proof and they are made for travelers, making them convenient for customers who are always on the move. Furthermore, the opaque or UV Protective materials used in the airless bottles keep light-sensitive lotions from spoiling and losing effectiveness.
For airless systems there is no comparison to traditional pumps or jars in terms of protection and efficiency. Regular pumps are built to trap air which leads to the waste of the product. With jars you can stick fingers into the product which is the best way to contaminate it. Airless pumps do not have this problem, and they also have a more safe way to dispense the product which is really important for products that are used on the face or sensitive skin.
