Polyquaternium refers to the presence of quaternary ammonium centers in the polymer. They are positively charged polymers and neutralize the negative charge of most shampoos and hair proteins thus making the hair lie flat. Polyquaternium-22 is a copolymer of acrylic acid and diallyldimethylammonium chloride, that works as an antistatic agent and hair fixative in cosmetics and personal care products.
