SLSA is a distinct molecule, not a variant of SLS/SLES. It is a sulfoacetate — a larger, higher-molecular-weight anionic surfactant with a much lower skin-penetration profile, which translates into reduced irritation potential. Unlike sulfates, it is fully compatible with sulfate-free positioning, and it produces a denser, creamier lather.
