About
A cleansing and foaming surfactant similar to sodium lauryl sulfate but with slightly milder properties, commonly used in personal care products.
Magnesium Lauryl Sulfate (MLS) is an anionic surfactant derived from lauryl alcohol, used primarily as a cleansing and foaming agent in shampoos, body washes, and toothpastes. While structurally similar to SLS, the magnesium cation reduces its irritancy profile somewhat. The EU surfactant monograph notes it is safe for use in rinse-off products at typical concentrations of 1-15%, though concentrated formulations may cause eye and skin irritation.
