    Sodium Lauryl Sulfoacetate and sodium lauryl/laureth sulfate are different in terms of chemical structure, molecular weight, etc.

    Sodium Lauryl Sulfoacetate (SLSA) is a larger compound than sodium lauryl sulfate (SLS). Both of them can be similarly used as foaming agents, surfactants, etc. SLSA seems give a less irritation then SLS, and also do not form scum with hard water.

    "stated that sodium lauryl/laureth sulfate can cause cancer" I cannot agree on this statement as the usual formulation in pharmaceutical (not cosmetic) products have this SLS rather than SLSA! both LD50 in rats (oral) > 2000 mg / kg. so, they should be safe to use.

    because some "health people" don't know about chemistry. yes, SLS can cause irritation, but not high risk of cancer (with evidence) ~ sometimes don;t trust the ads or unauthorized people say.
