The different Sodium Lauryl Sulfoacetate and sodium sulfate?
what is the different Sodium Lauryl Sulfoacetate and sodium lauryl/laureth sulfate.
- are they the same? if they are different what is the different?
- stated that sodium lauryl/laureth sulfate can cause cancer, then how about Sodium Lauryl Sulfoacetate?

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.Source(s): me, Handbook of Pharmaceutical Excipients (PharmPress), USP 27
