Expert Verdict
Moderate mildness - milder than SLS/SLES but less mild than the -16 variant; may cause dryness and irritation with overuse, particularly around eyes; 1,4-dioxane trace risk from ethoxylation process. The 5-EO chain provides a practical balance between cleansing power, foam generation, and skin compatibility; the magnesium counterion reduces the Krafft point and improves low-temperature solubility relative to sodium salts
