While washing my hands in a McDonald’s restroom the other day, it dawned on me why so many places are switching to foamy hand soap. I reckoned it isn’t happening because the foamy soap is generally nicer, it’s that it induces people to use less soap and thus saves companies money. And as a google search revealed, I was correct, but the advantages don’t stop there.
From WiseGeek
For manufacturers, the advantage of foam soap is that they do not need to make as much soap. They argue that foam soap is also easier to lather, encouraging people to use soap properly, and that since many people overuse soap, foam soap dispenses a more appropriate amount of soap for basic hand washing needs. Foam soap is also thinner, making the dispensers less prone to clogging.

You’ll get significantly more Handwashings out of the Foam Soap System than traditional liquid soap dispensers. Foam Soap combined with the dispenser will create a powerful cleaning system. Air is infused into the soap as it’s dispensed creating a rich, luxurious lather. Just ONE push delivers a generous portion of foam. The volume of lather feels so satisfying in users’ hands that they don’t need a second push.
As the chart shows, you actually get more than two-times as many pushes per unit volume with foam soap. So you not only end up with a product that’s more appealing to the customer, but one that uses less to begin with and encourages still encourages people to be less wasteful. What an invention!
