What's the role of Cetyl trimethyl ammonium chloride in fabric softener?

Hexadecyl trimethyl ammonium chloride is a quaternary ammonium salt surfactant commonly used as a softener and antistatic agent. In fabric softeners, CTAC can play the following roles:

• Soft Fabric: Cetyl trimethyl ammonium chloride can adsorb on the surface of fabric fibers, forming a thin film that makes the fabric soft and smooth. This can improve the texture of the fabric and increase its comfort.
• Anti static electricity: The static electricity generated by fabric friction is one of the common problems that people encounter. CTAC can reduce the electrostatic charge of fabrics, giving them anti-static properties and reducing the discomfort and troubles caused by static electricity.
• Improving the wrinkle resistance of fabrics: Due to the properties of its surfactants, Cetyl trimethyl ammonium chloride can help fabrics maintain good wrinkle resistance. It can change the surface tension between fabric fibers, reduce friction between fibers, and thus reduce wrinkles in the fabric.
• Improving the washing resistance of fabrics: Cetyl trimethyl ammonium chloride can react with salts and oils in water to form insoluble precipitates, thereby reducing the adhesion of stains to fabrics. This improves the washing and stain resistance of the fabric, extending its service life.
