What Is Sodium Lauroyl Methyl Isethionate?
Sodium lauroyl methyl isethionate is a cleansing agent that is noted in research for its gentleness on skin. It is known to play well with other ingredients, showing excellent formulary compatibility in body washes, facial cleansers, and shampoos.
Suppliers of this surfactant praise its “dense, luxurious foam and elegant after-feel,” as well as its ability to easily rinse from skin.
As a raw material, sodium lauroyl methyl isethionate takes shape as white to off-white flakes/chips. It’s also supplied as a clear light-yellow liquid. Like many surfactants, it can be naturally derived from coconuts, with the final version considered plant-derived or synthetic depending on manufacturing practices.
In 2017, the Cosmetic Ingredient Review Expert Panel deemed sodium lauroyl methyl isethionate safe as used in personal care products. Their report looked at products containing up to 10.1% concentration.
