How does a foaming soap dispenser work?

The soap is foamy when it comes out.


Answer by  Rob69 (32)

The foaming soap liquid is sucked through a tube and then compressed through a gauze together with air. The gauze makes that the air and foaming soap liquid are mixed and the result is a foam that comes out of the soap dispenser. Like you are mixing air into whipped cream to make it creamy.

Foaming dispensers have two chambers. The first is on the bottom. When you push the nozzle down, the soap is carried into the first chamber and in the second chamber, air is pushed in, thus making the foam. Since the soap is in the bottle is very thin, it get a better foam than liquid soaps.

After a while the dispensers stop working well and the nozzle doesn't pop back up fully. Why does this happen? Is it the spring inside?  add a comment

"Foaming soap dispensers" inject some air long with "watered-down" liquid body wash, detergent, shampoo, or soap to create the "foaming soap". Refill mixtures should be mostly (2/3rds to 4/5ths) water or the dispenser's pump will clog.

I believe when they make the bags ro load the soap dispenser the soap is put into the bags as a foam.


Answer by  champaign9497 (11977)

It is liquid in the dispenser bag and when it comes out the dispenser mixes it with air in turn causing it to turn to foam because it puts it under pressure as it comes down through the dispenser thats why the bags of soap last so long in the foaming dispensers.
