Verdict

Amphoteric betaine surfactants are among the mildest surfactant classes; low irritation potential; generally well-tolerated even on sensitive skin. An amphoteric (zwitterionic) surfactant with a 22-carbon behenyl chain; excellent foam-boosting and viscosity-building properties; functions as a co-surfactant to reduce irritation potential of primary anionic surfactants; good compatibility across a wide pH range

US Note

Allowed - not prohibited or restricted; betaine-class surfactants are broadly accepted
