  • Applications

    Lauryl Isoquinolinium Bromide (CAS 93-23-2) is a quaternary ammonium cationic surfactant primarily used in cleaning formulations and industrial or household cleaners to provide surface activity, wetting, and oil emulsification. It is commonly employed as a conditioning surfactant in cosmetics and personal care products, contributing to conditioning and enhanced feel. It also serves as a surface-active additive in coatings and inks to improve pigment dispersion and gloss, and in polymer and plastic processing it may act as an emulsifier or stabilizer for formulations involving cationic polymers. In textiles and industrial finishing, it can function as a finishing agent or surfactant to enhance wetting and processing efficiency.
