Science
Mechanism of Action
As an amphoteric molecule containing both positive and negative charges, it reduces the surface tension of water to lift and emulsify sebum and debris. Its unique zwitterionic structure allows it to provide conditioning benefits that neutralize static and soften the skin, making it significantly milder than traditional anionic surfactants.

Key findings
- 01 Clinical in-use testing confirmed no adverse reactions, including zero irritation or pigmentary changes, with related alkyl sultaines.
- 02 High-concentration rabbit studies on related Lauryl Hydroxysultaine identified slight dermal irritation, confirming safety at standard cosmetic dilutions but indicating a clear upper threshold.

Dusting Analysis
This ingredient is typically a functional surfactant rather than a marketing 'hero.' However, in formulations claiming to be 'extra-gentle,' concentrations below 1% may indicate it is being used merely for foam boosting rather than as a primary, skin-friendly cleansing agent.
The Formula
Formulation
Stability
Demonstrates exceptional stability across a vast pH spectrum, maintaining efficacy in both highly acidic and alkaline environments. It is chemically compatible with anionic, cationic, and nonionic surfactant systems.
