Sodium Lauroyl Methyl Isethionate (SLMI) is a gentle anionic surfactant derived from coconut-based fatty acids and isethionic acid, used to cleanse and produce a soft, creamy lather in syndet bars, facial cleansers, and body washes. It is valued for its mildness relative to harsher sulfates and good compatibility with sensitive skin.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient skin dryness | Uncommon | Possible with frequent use or high concentrations, generally less than with sulfate surfactants |
| Skin irritation or stinging | Rare | Reported infrequently, typically in already compromised or very sensitive skin |
| Eye irritation | Uncommon | Can occur on direct ocular contact, though milder than many surfactants |
| Allergic contact dermatitis | Very rare | Few documented cases; SLMI is considered a low-sensitizing ingredient |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
