Verdict
Long-chain C22 quaternary ammonium cationic surfactant confirmed safe as used by CIR. Superior conditioning for thick, coarse, and curly hair types due to enhanced substantivity from the C22 hydrophobic tail. Used at 0.5–3% in rinse-off conditioners. Incompatible with anionic surfactants.
US Note
CIR assessed behentrimonium chloride as safe as used. C22 long-chain quat — enhanced substantivity to hair shaft vs shorter-chain quats. Preferred conditioning agent for thick, coarse, and curly hair types. Incompatible with anionic surfactants.
