Common Name(s): Amphoteric surfactant,mild broad ph stable,conditioning co-surfactant
CAS Number: N/a
DESCRIPTION
What It Does: Provides amphoteric mild cleansing with broad ph compatibility.
Why It's Used: Amphoteric ph-flexible surfactant โ the ability to adopt cationic, zwitterionic, or anionic character depending on ph provides inherent compatibility with all other surfactant charge types and low irritation from reduced net charge density at cosmetic formulation ph.
How It Works: Fatty chain + amino acid derivative + amphoteric chemistry. ph-dependent character. mild. broad compatibility. low irritation. baby/sensitive suitable. conditioning.
Typically Found In: Mild cleansers,baby products,sensitive skin

Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Amphoteric ph character: below isoelectric point (typically ph 4-5): cationic character provides conditioning substantivity; at isoelectric point (ph ~6-7): net zero charge, minimum irritation, maximum compatibility; above isoelectric point (ph>8): anionic character provides cleansing. cosmetic formulations at ph 5-7 position amphoterics near their isoelectric point โ the minimum-irritation maximum-compatibility condition explaining the preferred use of amphoterics in mild sensitive skin systems.
