Polyquaternium-67

Polyquaternium-67 is a synthetic polymer — a long-chain molecule built from repeating units — that carries a positive electrical charge. It is water-soluble and commonly used in hair and scalp care formulations.This ingredient functions primarily as a conditioning agent and film-former. It works by adhering to the hair shaft and scalp surface, where it deposits a thin, protective coating that can improve texture and manageability.

Polyquaternium-67 is positively charged, which allows it to bond electrostatically to hair and skin surfaces, which are negatively charged. Once deposited, it forms a thin film that can help retain moisture and improve the smoothness of the hair shaft.The antistatic effect occurs because the polymer neutralises electrical charges that build up on hair, reducing the friction that causes frizz.

Polyquaternium-67 is typically found in rinse-off products such as conditioners and scalp treatments. In these formulations, it is applied to damp hair or scalp, left for a brief period, and then rinsed away. Follow the product instructions for optimal results. It can be used as part of a daily hair care routine.

Polyquaternium-67 is generally well-tolerated and approved for use in cosmetics across major regulatory bodies. It is water-soluble and rinses away easily, minimising the risk of build-up or irritation in most individuals.
