Expert Verdict

No publicly documented safety issues. Arginine-based cationic surfactants are generally mild and well-tolerated. Cationic conditioning agent based on the amino acid arginine, ether-linked to cetearyl (C16-C18) fatty alcohols; provides substantivity to hair and skin via electrostatic attraction to negatively charged surfaces; the longer cetearyl chain offers enhanced conditioning and emolliency compared to shorter-chain analogues
