Just the Right Amount of Foam
In many countries around the globe, washing is still done by hand. People believe it ought to foam properly – because that’s supposed to be a sign of effective cleaning. Yet this foaming is a problem, since after washing, laundry has to be rinsed out many times until all of the foam disappears. This is why researchers at WACKER have developed a defoaming agent that only begins to take effect during rinsing, halving the amount of water used.
