>> Product Introduce
Di(hydrogenated tallow)dimethyl ammonium chloride (DHTDMAC)
CAS 61789-80-8
Di(hydrogenated tallow)dimethyl ammonium chloride (CAS 61789-80-8) is a high-performance cationic surfactant derived from hydrogenated tallow fatty acids, typically appearing as an off-white to light yellowish paste or waxy solid at room temperature, and is commercially available in various concentrations including 74-77% active matter for industrial applications and 50% aqueous solutions for easier handling. As a quaternary ammonium compound, it functions primarily as an exceptional fabric softener and antistatic agent, adsorbing onto negatively charged textile fibers to reduce inter-fiber friction and impart a soft, fluffy hand feel while effectively eliminating static cling in both household laundry and industrial textile finishing processes. Beyond textiles, it serves as a powerful conditioning and detangling agent in personal care products such as hair rinses and conditioners, improving hair manageability by repairing cuticle damage and enhancing gloss without weighing hair down. In industrial applications, it acts as an effective emulsifier and modifier in the production of organoclays for paints, greases, and drilling fluids, provides biocidal properties for disinfection in water treatment and institutional laundering, and functions as a phase transfer catalyst in organic synthesis. Due to its cationic nature, it is incompatible with anionic surfactants and requires gentle heating to 35-40°C prior to use to facilitate homogeneous incorporation into formulations, and it should be stored in a cool, dry, well-ventilated area away from oxidizing agents to maintain product stability and performance integrity over time.
>> Main Uses
Di(hydrogenated tallow)dimethyl ammonium chloride (DHTDMAC, CAS 61789-80-8) is primarily used as a fabric softener and antistatic agent in textile and laundry applications, where it adsorbs onto fibers to reduce friction and impart a soft, fluffy hand feel while eliminating static cling in both household rinse-cycle softeners and industrial textile finishing processes; it also serves as a hair conditioning agent in personal care products such as rinses and conditioners, providing excellent detangling, wet combing, and gloss enhancement by repairing damaged hair cuticles; additionally, it functions as an emulsifier and modifier in industrial applications including organoclay production for paints and greases, as a biocide for disinfection in water treatment and institutional laundering, and as a processing aid in paper softening and phase transfer catalysis in organic synthesis.
