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).

Polyelectrolytes with amphiphilic counterions, PEACs, are water insoluble because the amphiphiles self-assemble into highly charged micelles that strongly associate with the equally highly charged polyions. However, in the presence of water soluble cyclodextrins (CDs) that form inclusion complexes with the
