What are Bubble Bars??
A bubble bar is a mixture of ingredients that form a putty, or in most cases a "bar" of solid bubble bath. As the product is ran under warm water, it create bubbles in the same fashion as a liquid form of bubble bath. After the product has been ran under the water, take yours hands and agitate the water for piles of bubbles.
One of the main bubble making ingredients is Sodium Lauryl Sulfoacetate (SLSa), which is derived from plants, more known as coconut or palm oils. Its a safer, more skin friendly alternative to the known foaming agent Sodium Lauryl Sulfate.
Most bubble bars can be used in multiple baths, giving a small amount of bubbles, all the way to using the whole bar and enjoying a luxury of bubble mounds.
