Allyltrimethylammonium chloride is widely used in the synthesis of polymers, particularly in the production of cationic polyelectrolytes. These polymers are essential in water treatment processes, where they act as flocculants to remove suspended particles and clarify water. Additionally, it is employed in the textile industry as a fabric softener and antistatic agent, improving the handling and feel of fabrics. In the paper industry, it serves as a retention aid, enhancing the strength and quality of paper products. Its cationic properties also make it valuable in personal care products, such as hair conditioners, where it helps to smooth and detangle hair. Furthermore, it finds application in the oil and gas sector as a clay stabilizer, preventing the swelling and migration of clay particles during drilling operations.
