Introduction of excellent properties of quaternary ammonium

The quaternary ammonium salt type cationic surfactant is formed by substituting four hydrogen atoms of the ammonium salt with an organic group, and is usually obtained by reacting a tertiary amine with an alkylating agent. The quaternary ammonium salt cationic surfactant has a strong basicity, does not produce a free amine in an alkaline solution, and is stable in nature. The quaternary ammonium salt type cationic surfactant has many excellent properties and can be used as an antistatic agent, a softening agent, a retarding agent, a fixing agent, etc. of a fiber, and can also be used as a hair styling agent for a disinfectant and a hair cosmetic. . According to the structure, the quaternary ammonium salt type cationic surfactant can be classified into an alkyltrimethylammonium salt type, a dialkyldimethylammonium salt type, an alkyldimethylbenzylammonium salt type, and the like.
