Trihydroxyethylmethylammonium Methylsulfate (THAMS)
CAS 29463-06-7
Trihydroxyethylmethylammonium Methylsulfate (CAS 29463-06-7) is a high-purity quaternary ammonium compound supplied as a colorless to pale yellow viscous liquid. It features excellent water solubility, thermal stability, and surface-active properties, making it a versatile additive across multiple industries. As an effective antistatic agent, it is widely used in polymer processing (such as polyurethane, plastics, and synthetic fibers) to reduce surface resistivity and prevent static charge accumulation. In organic synthesis, it serves as a reliable phase transfer catalyst, facilitating reactions between immiscible phases to improve yield and efficiency. Additionally, it functions as a conditioning agent in textile auxiliaries and personal care formulations, imparting softness, detangling properties, and static control.
>> Main Uses
Trihydroxyethylmethylammonium Methylsulfate (THAMS, CAS 29463-06-7) serves as a versatile multifunctional additive across diverse industrial sectors. As an effective antistatic agent, it is widely incorporated into polymer processing applications including polyurethane, polyvinyl chloride, polyethylene, and engineering plastics, where it migrates to material surfaces to form a hydrophilic layer that absorbs moisture and dissipates static charges, making it essential for electronic packaging, cleanroom flooring, automotive interiors, and textile fibers. In organic synthesis, it functions as a highly efficient phase transfer catalyst, facilitating nucleophilic substitutions, alkylations, and polymerization reactions by enabling reactants to interact across immiscible aqueous and organic phases, thereby improving reaction rates, product yields, and process efficiency in pharmaceutical intermediates, agrochemicals, and specialty chemical manufacturing. Additionally, it serves as a conditioning additive in textile finishing to impart softness, lubricity, and durable antistatic properties to natural and synthetic fibers, while in personal care formulations such as shampoos, conditioners, and leave-in treatments, it provides detangling, smoothness, and static control with mild conditioning benefits and easy rinseability.
