Quaternary Ammonium Salts in Organic Silicon Industry

At present, silicone products are gradually becoming a very important industrial raw material, such as silicone oil, silicone rubber, silicone oil lotion and so on. Our quaternary ammonium salt is widely used in the production of silicone, especially in the production of silicone oil lotion. However, the variety of applications is relatively concentrated, with the most commonly used being Dodecyl dimethyl benzyl ammonium chloride and Dodecyl dimethyl benzyl ammonium bromide.

According to literature reports, the use of Cetyl trimethyl ammonium chloride, Cetyl trimethyl ammonium bromide, Octadecyl trimethyl ammonium chloride, and Octadecyl trimethyl ammonium bromide is also very widespread in many countries. Especially in the production of fabric finishing agents, cationic surfactants are used as emulsifiers to achieve the softness, anti-static properties, improve the texture, elasticity, smoothness, and waterproofing of fabrics, Sometimes Tetramethyl ammonium hydroxide is also used as a catalyst for the reaction. However, usually if cationic emulsifiers are used alone, the effect is not very good, resulting in oil bleaching and demulsification, and it is difficult to use them in the same bath with multiple raw materials. In order to make the lotion more stable and maintain the above characteristics, it is generally necessary to add some non-ionic surfactants (such as alkyl phenol polyoxyethylene ether) for compounding, so that the lotion obtained has the characteristics of cationic dairy industry and can ensure the stability of lotion.
