Unlike SLS, SLSA is completely safe for most skin types, including sensitive skin. It removes oils and bacteria without irritating the skin. What throws people off when they look at these two ingredients is the first two words being identical, and from there, it’s assumed that they must be very similar. For those who suffer skin irritation, SLSA is not harsh as a cleanser. You could even go so far as to say it’s skin-friendly. It’s used as a foaming agent, wetting agent, or emulsifier in many hair care, body care, and personal care products.
