Xcellerate 35 Sodium lauryl sulfate (SLS) which is a strong foaming agent (chemically known as a surfactant) is responsible for giving lather to products like shampoos, face washes, detergents etc. It is not only harmful to the environment but studies have proven that it can cause skin problems, male infertility and is also carcinogenic. There is a misconception that products that give lather are high-quality. The fact is you can clean with little lather too. Foam or bubbles are visually very appealing, but in actuality too much lather is not required to clean either your hair or your clothes.
