What is the relationship between 1831, 1631 and how do I tell them apart?
1831 refers to octadecyl (C18) trimethyl ammonium chloride and 1631 to cetyl (C16) trimethyl ammonium chloride; the digits indicate carbon chain length and functional group. Both are cationic surfactants with similar softening, antistatic and emulsifying performance, selected by desired skin feel and solubility.
What is octadecyl trimethyl ammonium chloride (1831) mainly used for?
1831 is widely used in hair conditioner and cosmetic conditioning emulsification, fabric softeners, fiber antistatic agents, asphalt/silicone oil emulsification, waterproof coatings, organic bentonite modification, protein flocculation in biopharma, water treatment flocculation, and disinfection.
Does 1831 come in paste and liquid forms? How do I choose?
1831 is commonly available as a high-active paste (around 70%, alcohol-based) and a low-active liquid (around 30%, water-based). Paste has higher concentration and lower logistics cost, while liquid is convenient for direct blending. Choose based on your process and active-content needs, and confirm with Bio-CORNIGS.
What information should I provide to get a 1831/OTAC quotation?
