Sodium Lauryl Sulfate (SLS) is a common ingredient found in many personal care products, such as shampoos, toothpaste, and body washes. It is a surfactant, which means it helps to create lather and remove dirt and oil from surfaces. SLS is effective at breaking down grease and is often used in cleaning products as well. While SLS is widely used, it can sometimes cause skin irritation for sensitive individuals. As a result, some brands offer SLS-free alternatives to cater to those who prefer gentler formulations. Understanding the role of surfactants like SLS can help consumers make informed choices about their personal care products.
