Product Efficiency: Foam spreads much farther than liquid, so you use ~15-25% less product per hand wash. The foam clings to the skin without dripping.
User Experience: The foam feels soft and luxurious. It requires no lathering, making it faster and more convenient.
Cleaning Effectiveness: Foam can encapsulate dirt and grime more easily and has greater surface area contact with the skin or surface.
Hygiene: It's a touch-free enabler (when paired with an automatic sensor), reducing cross-contamination.
