Is SLSA good for sensitive skin?

Sodium Lauryl Sulfoacetate

Also known as: SLSA

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.
