Science
Mechanism of Action
This amino acid alkyl amide functions by lowering the surface tension of water, which aids in the efficient removal of dirt and impurities from the skin. Beyond its primary role in cleansing and emulsification, its fatty acid components contribute to skin nourishment and protection, promoting hydration and softening, and helping to maintain skin elasticity. It is notably effective at producing a rich foam, particularly under weakly acidic conditions.

Stability
This ingredient produces a rich foam in weakly acidic conditions. While an optimal pH range for its stability is not explicitly defined, similar amino acid surfactants are generally stable and effective within pH ranges such as 5.0-8.0.
Conflicts
- Must not be used in cosmetic products where N-nitroso compounds may be formed due to potential safety concerns.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed Sodium Cocoyl Threoninate within the Amino Acid Alkyl Amides class, deeming them safe for cosmetic use, provided products are formulated to be non-irritating. A critical restriction is to avoid its use in formulations where N-nitroso compounds could potentially form. While specific maximum concentrations for Sodium Cocoyl Threoninate were not detailed, related acyl sarcosines and sarcosinates were considered safe in rinse-off products and at concentrations up to 5% in leave-on products.
