Polyquaternium-10
The question

Is Polyquaternium-10 safe in conditioner?

ClearedConditioner

A cationic polymer used as a hair conditioner and antistatic agent. The CIR approves concentrations up to 2%. Non-irritating, non-sensitizing, non-genotoxic, and approved in all major regulatory markets. Does not penetrate skin — remains on the hair surface.

What the research flags

  • Slight eye and skin irritation possible above 2% — well within safety limits at typical use concentrations
