Polyquaternium-22 is a multifunctional polymer and it is used in cosmetic formulations. Polyquaternium-22 acts as an antistatic (reduces static charges by neutralizing the electrical charge on the hair surface)and as hair conditioner and combability aid (reduces or prevents the confusion of the hair due to changes or damage to the hair surface and thus improves the combability). This is because the molecules of the Polyquaternium-22 are positively charged. They attach themselves to the (negatively charged) hair shaft and form a coherent film (film former) on the hair surface. This makes the hair appear smoother and easier to comb.
