Are 1631, CTAC and cetrimonium chloride the same product?
Yes. 1631, CTAC and cetrimonium chloride all refer to hexadecyl (C16) trimethyl ammonium chloride, CAS 112-02-7. They are different names for the same product, a cationic surfactant commonly available in paste and liquid forms.
What is the difference between 1631 and 1831?
1631 is hexadecyl (C16) trimethyl ammonium chloride and 1831 is octadecyl (C18) trimethyl ammonium chloride; the difference is carbon chain length. Both are cationic surfactants with similar softening, antistatic and emulsifying performance, selected by skin feel, solubility and phase-transfer catalysis needs.
What is hexadecyl trimethyl ammonium chloride mainly used for?
1631 is widely used in hair conditioner and cosmetic conditioning emulsification, fabric softeners, fiber antistatic agents, silicone/asphalt emulsification and waterproof coatings, and as a phase-transfer catalyst in pharmaceutical and fine chemical synthesis, as well as in paper, leather, water treatment flocculation and disinfection.
