Science
Mechanism of Action
This ingredient functions primarily as a mild surfactant, effectively lowering surface tension to facilitate the thorough removal of impurities from the skin. It also acts as an efficient foaming agent, producing a rich lather, and an emulsifier, proficiently blending oil and water-based components to achieve stable, uniform product textures. Critically, Sodium Methyltaurate's derivatives are known to cleanse without compromising the skin's natural pH or disrupting the skin barrier, leaving the complexion feeling moist and smooth.

Stability
Sodium Methyltaurate is water-soluble and demonstrates good stability, though its derivatives are susceptible to hydrolysis when exposed to strong acidic or alkaline conditions. The optimal pH range for stable formulations typically falls between 5.0 and 8.0, with high heat also noted as an incompatibility.

Safety
Safety Profile
The CIR Expert Panel concluded that Sodium Methyltaurate is safe for cosmetic use when formulated to be non-irritating. However, studies have shown that high concentrations, specifically 35-37% and 80-84%, can induce severe and irreversible eye damage, including persistent corneal opacity and inflammation. While no general maximum safe concentration for Sodium Methyltaurate itself is provided, a related derivative, Sodium Methyl Oleoyl Taurate, has been reported safe for use up to 28% in bath products.
