Sodium Lauroyl Methyl Isethionate

Explained

Sodium Lauroyl Methyl Isethionate is a gentle, sulfate-free cleansing agent. It's basically a mild "soap" molecule derived from coconut that makes a soft, cream foam and is very soluble in water.

Typical concentration use ranges from ~0.6-10% in rinse off products and only trace amounts (~0.009%) in leave on products.

The Cosmetic Ingredient Review Expert Panel has assessed it and concluded it to be safe as used at these concentrations when formulated to be non-irritating.

Allergy and sensitization risk is low and often when someone reacts to a cleanser it's due to the fragrance or preservatives rather than this ingredient itself.
