Where do the bubbles come from when there’s no Sodium Lauryl Sulfate(SLS) in your soap?
    A lot of myths surround the notion that Sodium Lauryl Sulfate (SLS) equals bubbles in a bath product and if it does not contain SLS, it won’t foam up. That's not entirely true — normal water have a high water tension (think of it as being stiff) and to form bubbles,you need to lower the water tension (think of it as being flexible). To do that, a foaming agent, also known as surfactant, to lower the water tension is added. Soap itself is a natural surfactant whereas SLS is a synthetic man-made chemical which behaves similarly like soap.
