FAQ
What is the difference between a mist, a spray, and an aerosol?
The primary difference lies in the propellant and droplet size. A cosmetic spray pump and a mist pump are "non-atomizing" or "mechanical" sprayers. They use a manual pump to force liquid through a nozzle, creating droplets. "Mist" typically refers to a finer spray with smaller droplets (30-60μm). An "aerosol," on the other hand, uses a pressurized propellant (like butane or propane) to forcefully expel and atomize the product into very fine particles. Aerosols often provide a more consistent spray from any angle but have environmental considerations, whereas mechanical pumps are more sustainable and user-friendly for cosmetics.
Can any cosmetic spray pump be used for oils or serums?
No, using the wrong pump will lead to poor performance or complete failure. The key factor is the viscosity of the product. Standard cosmetic spray pumps are designed for low-viscosity liquids like toners or water. For thicker products like facial oils, serums, or liquid sunscreens, you need a specific "high-viscosity" or "oil" pump. These pumps feature a wider dip tube, a more powerful spring, and a larger nozzle orifice to handle the thicker liquid without clogging. Always check the pump's viscosity rating (measured in centipoise, cP) against your product's specifications.
How do I fix a clogged makeup or setting spray pump?
A clogged pump is often caused by formula residue drying in the nozzle. Here are the steps to fix it:
- Remove the pump from the bottle.
- Rinse the nozzle under warm (not hot) water to dissolve the residue.
- For stubborn clogs, submerge the entire pump head in a small bowl of warm water for a few minutes.
- Pump the water through the nozzle several times to flush it out.
- Air dry completely before reattaching it to the bottle to prevent diluting your product.
To prevent clogs, always wipe the nozzle clean after each use and ensure the cap is on securely.
Are cosmetic spray pumps recyclable?
This is a complex issue because a single pump is made of multiple materials (plastic body, metal spring, rubber gasket). Most municipal recycling facilities cannot process these mixed materials. Therefore, the best practice is to separate the pump from the bottle before recycling. The bottle (glass or plastic) is widely recyclable. The pump, unfortunately, often ends up in landfill. However, the industry is innovating. As a manufacturer, we are actively developing mono-material pumps (made entirely from one type of plastic, like PP) and designs that are easier to disassemble, which will significantly improve their recyclability in the future.
What does "360-degree spray" mean, and do I need it?
A "360-degree spray" (or "all-angle spray") pump is engineered with a special valve system that allows it to function correctly when held upside down or at any angle. A standard pump relies on gravity to keep the liquid at the bottom of the dip tube; if you tilt it too far, it will draw in air and stop spraying. You need this feature if your product is designed for use on hard-to-reach areas, such as a hair spray for the back of the head, a body sunscreen for legs and back, or a household cleaner for under surfaces. For products typically used upright, like facial toners, it is an added convenience but not a necessity.
