Sodium Lauryl Sulfoacetate (SLSA) is a mild, plant-derived surfactant that creates a rich and stable foam. It is often used as an alternative to harsher sulfates, providing effective cleansing without stripping the skin or hair of natural oils. SLSA helps to emulsify oils and dirt, allowing them to be rinsed away easily.

Despite having 'sulfate' in its name, Sodium Lauryl Sulfoacetate is not a sulfate in the same chemical class as Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES). It is a much milder surfactant.
Is SLSA good for sensitive skin?
SLSA is generally considered a mild surfactant and is often used in products marketed for sensitive skin. However, like any cleansing agent, it can cause mild irritation in individuals with extreme sensitivity.
