Sodium Methyl Cocoyl Taurate

Sodium Methyl Cocoyl Taurate is a mild anionic surfactant commonly used in cleansers (often a few to ~15% in the surfactant blend) and is generally less irritating than traditional sulfates, with good skin and eye tolerability in rinse-off use. However, as a true detergent it can still disrupt barrier lipids and increase transepidermal water loss in eczema-prone or over-washed skin, so I rate it as gentle rather than very gentle for highly reactive patients. Safety Notes: In consumer products, Sodium Methyl Cocoyl Taurate is most often used in rinse-off cleansers as a mild primary or secondary surfactant; at the low end (~0.2–1%) it appears as a co-surfactant/foam booster or mildness modifier in sulfate-free face washes and body washes. Mid-range usage (~3–12%) is common for primary cleansing systems in gentle syndet-style gels/creams, while high-strength OTC formats (solid shampoo bars, syndet cleansing bars, and ultra-mild baby cleansers) can reach ~15–25% as part of the total surfactant blend (higher in solids, lower in liquids). Leave-on usage is uncommon and generally limited to trace/low levels when present.
