General description

Dodecyltrimethylammonium chloride is a quaternary ammonium compound (QAC) commonly used as a cationic surfactant. It is used in antimicrobial sanitizers due to its surface activity and germicidal efficiency.

Application

  • Polyethylene terephthalate depolymerization: Dodecyltrimethylammonium chloride was applied in the enzymatic depolymerization of polyethylene terephthalate, illustrating its utility in enhancing the efficiency of plastic degradation processes (Kawai et al., 2022).

Femtosecond fluorescence upconversion experiments were performed on the naturally occurring medicinal pigment, curcumin, in anionic, cationic, and neutral micelles. In our studies, the micelles are composed of sodium dodecyl sulfate (SDS), dodecyl trimethyl ammonium bromide (DTAB), and triton X-100 (TX-100).
