Science
Mechanism of Action
As a zwitterionic molecule, it adjusts its charge based on the formulation pH to effectively emulsify debris and oils without compromising the skin barrier. It organizes into large mixed micelles that are too substantial to penetrate the stratum corneum, thereby preventing the 'stripping' effect and leaving a silky, substantive film on the skin's surface.

Clinical Evidence

Key findings
- 01 A CIR Expert Panel assessment confirmed that concentrations between 0.5% and 1.72% active matter show zero dermal irritation or allergic sensitization in HRIPT clinical trials.
- 02 Safety data published in the International Journal of Toxicology indicates that leave-on concentrations should be capped at 3% active to maintain a clean safety profile regarding trace impurities.

Dusting Analysis
Because this ingredient is primarily used to improve the mildness and foam quality of a cleanser, using it at 'dusting' levels (below 0.1%) would fail to provide the necessary micellar buffering required to protect sensitive skin.
The Formula
Formulation
Stability
Highly stable between pH 4.0 and 9.0, with peak performance and skin compatibility between pH 5.5 and 7.5. It provides excellent viscosity control with minimal salt requirements.
Synergies
- Anionic surfactants
- Glycerin
- Cationic polymers
Conflicts
- Nitrosating agents
- Strong oxidizing agents
Safety
Safety Profile
Safety is dependent on high-purity sourcing; impurities like DMAPA must be strictly limited to less than 0.01% to prevent sensitization.
