Tridodecylmethylammonium chloride (TDMAC) is a quaternary ammonium salt extensively utilized in diverse scientific and industrial fields. It serves as a cationic surfactant produced by the reaction between tridodecylmethylamine and hydrochloric acid. Tridodecylmethylammonium chloride functions by reducing the surface tension of water, acting as a surfactant. It also acts as an emulsifier, facilitating the creation of stable emulsions. Due to its cationic properties, it can effectively bind with anionic substances like proteins, forming stable complexes. Moreover, Tridodecylmethylammonium chloride exhibits antifungal properties by disrupting the cell membrane of fungi.
