Ammonium Lauryl Sulfate (ALS) is a widely used surfactant in personal care products like shampoos, bath products, and cleansers. Derived from coconut oil, ALS acts as a powerful cleansing and foaming agent, effectively removing dirt and oils from both skin and hair. When mixed with water, it creates a rich lather, making it ideal for its cleaning and emulsifying properties. ALS is generally safe for use in cosmetics when used in appropriate concentrations, although excessive use or sensitive skin types may find it drying.
