Dodecyltrimethylammonium chloride
Wide Range of Active Content: The product is offered in two grades: one with an effective content of 32–35% (present as a light yellow liquid) and another with 49–52% (a viscous liquid), offering adaptability to various application needs.
Excellent Chemical Stability: Both variants maintain their chemical integrity over time, guaranteeing reliable and consistent performance.
Superior Resistance: The product demonstrates exceptional resilience to high temperatures, light exposure, strong acids, and alkalis, enabling dependable operation under demanding conditions.
Outstanding Functional Properties: It possesses remarkable permeability, emulsifying, antistatic, and bactericidal capabilities, making it highly effective across diverse industrial uses.
Dodecyltrimethylammonium Chloride (DTAC) is offered in two specifications. The first specification has an active content of 32–35% and presents as a light yellow liquid. It solidifies at -15℃, has a relative density of 0.981 g/cm³, an HLB value of 17, and an open-cup flash point of 60℃. The second specification contains 49–52% active content and is supplied as a viscous liquid. It has a solidification point between -12℃ and -9℃, a density of 0.892 g/cm³, an HLB value of 17.1, and an open-cup flash point below 27℃. A 10% aqueous solution of this grade exhibits a surface tension of 33×10⁻³ N/cm. Both variants are fully miscible with water and demonstrate high chemical stability. They offer strong resistance to heat, light, strong acids, and alkalis. Additionally, they provide excellent permeability, emulsification, antistatic, and bactericidal properties.
