SLS, or Sodium Lauryl Sulfate, is a common ingredient found in many personal care products, such as shampoos, toothpaste, and body washes. It acts as a surfactant, helping to create lather and remove dirt and oil from surfaces. SLS is known for its ability to produce foam, making it popular in cleaning and cosmetic formulations. While SLS is effective in cleansing, it can sometimes cause skin irritation for sensitive individuals. As a result, some brands offer SLS-free alternatives for those who prefer gentler options. Understanding the role of SLS can help consumers make informed choices about their personal care products.
