By making use of the Bag-on-Valve Instant Foam Technology™, the concentrated products are converted during dispensing into a rich, firm foam with high cleansing action. The tin cartridge contains a laminated bag that is attached to a valve, nozzle and cap. Pure air is injected between the can and the bag, before the bag is filled with soap. This increases the pressure and causes the bag to empty completely
Thanks to the Bag-on-Valve Instant Foam Technology™ and highly concentrated Dreumex Omnicare™ Foam Soap, a dose of 0.2-mL Dreumex Omnicare™ Foam Soap per hand wash is adequate for optimum hand cleansing. Other touch-free dispensers dose at least 0.4-mL per wash. Therefore, 400-mL of soap is enough for 2,000 hand washes. This is more than the typical one-liter package of competitive products.
Usage with a manual dispenser is a minimum of 2 doses per hand wash. This makes the consumption of soap with some manual dispensers up to 10 times higher than with Dreumex Omnicare™.
