Sodium Methyl Cocoyl Taurate
Sodium Methyl Cocoyl Taurate
Mild taurine-derived surfactant. Common in low-irritation Japanese and Korean foaming cleansers.
What it does
Sodium methyl cocoyl taurate is an anionic surfactant in the same gentleness tier as sodium cocoyl isethionate. It produces a soft lather, rinses cleanly, and tolerates a wide pH range — which is why it's a frequent pick in J-beauty and K-beauty foaming cleansers that need to rinse fully without leaving residue. Mild enough for daily use even on dry or sensitive skin.

Adding more steps does not equal more efficacy.Draelos 2018 · Journal of Cosmetic Dermatology ↗
