  • Applications

    Lauramidobutyl guanidine acetate (CAS 161865-39-0) is used primarily as a cationic surfactant and conditioning agent in cosmetics and personal care products, where it helps soften hair and improve wetting and foaming characteristics. It also serves in household cleaners and laundry formulations as a surfactant and emulsifier to boost cleaning performance and formulation stability. In industrial manufacturing, it can function as an emulsifier or processing aid in polymers, coatings, and inks, aiding dispersion and compatibility of ingredients. Additionally, it is evaluated as a surface-active additive in specialty coatings, adhesives, and other engineered formulations.
