Dodecylbis(hydroxyethyl)methylammonium chloride (DDHMAC)
CAS 22340-01-8
Dodecylbis(hydroxyethyl)methylammonium chloride (CAS 22340-01-8) is a high-purity quaternary ammonium cationic surfactant with the molecular formula C₁₇H₃₈ClNO₂ and a molecular weight of 323.94. This versatile surfactant exhibits excellent emulsifying, conditioning, antistatic, and biocidal properties, making it widely used in personal care products such as hair conditioners and skin care formulations, textile softeners and lubricants, water treatment biocides and algaecides, as well as oilfield clay stabilizers for drilling and fracturing fluids. With good solubility in water and alcohols, stable performance below 85°C, and reliable compatibility with other ingredients, DDHMAC delivers consistent and high-performance results across diverse industrial and consumer applications.
>> Main Uses
Dodecylbis(hydroxyethyl)methylammonium chloride (DDHMAC, CAS 22340-01-8) serves as a versatile cationic surfactant across multiple industries. In personal care, it functions as a conditioning agent, emulsifier, and antistatic agent in hair conditioners, hair dyes, skin care lotions, and shampoos, imparting softness, smoothness, and improved combability while enhancing product stability and texture. In the textile industry, it acts as a softener, lubricant, and antistatic agent to improve fabric hand feel, reduce static buildup, and facilitate processing operations such as spinning, weaving, and finishing. For water treatment applications, DDHMAC provides effective biocidal and algaecidal activity in circulating cooling water, industrial process water, and oilfield injection systems, preventing biofilm formation and system fouling. In oilfield applications, it serves as a clay stabilizer in drilling fluids and fracturing fluids, effectively inhibiting clay swelling and migration to preserve formation permeability. Additionally, it is widely employed in papermaking as a softening agent, in leather processing as a fatliquoring auxiliary, and in coatings and industrial formulations as an emulsifier and dispersant, delivering reliable performance across a broad range of industrial and consumer applications.
