By making use of the Bag-on-Valve Instant Foam Technology, the concentrated soaps are converted, during dispensing, into a rich, firm foam with high cleansing action. The cartridge consists of a laminated bag that is attached to a valve, a cartridge (tin), 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 Foam Soap, a dose of 0.2 ml Foam Soap per hand wash is adequate for optimum hand cleansing, whereas 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 pack of competitive products.
Usage with a manual dispenser is minimum 2 doses per hand wash. This makes the consumption of soap with some manual dispensers up to 10 times higher than with
Dreumex Omnicare.
