Yessi Pratiwi — August 30, 2007 / 12:41 am
Soap bubbles that collapse once clothes are clean could reduce the water needed during washing. A soap bubble is a very thin film of soap water. Their shape is a hollow, round ball, or sphere. They have a colorful surface. Soap bubbles do not last very long. Sometimes they break in the air. When they touch something else, they usually break.
When people talk about soap bubbles they think about them being pretty, but short-lived. So, they are a symbol for other things that are pretty, but short-lived or unimportant. But lately, researchers at the University of Queensland in Brisbane, Australia, have made a “pepfactant”, which only forms bubbles under mildly alkaline conditions, American Scientist reported. Detergents tend to be alkaline, so during a wash cycle the molecules link to form bubbles. The rinse water lowers the pH, breaking the bubbles apart, so less water is needed to wash out the lather. Pepfactants could also control the mixing of oil and water in industrial processes.
