  • Applications

    Pentyl rhamnoside (CAS 494844-53-0) is typically used as a nonionic surfactant and emulsifier in formulation development. In cosmetics and personal care it provides mild cleansing and emulsion stability. In household and professional cleaners it improves wetting and dispersion of actives. In coatings and inks it acts as a wetting and dispersing agent, enhancing substrate coverage. In polymer and plastics processing it can serve as a processing aid or compatibilizer, aiding dispersion and formulation stability. In industrial manufacturing, it is used as a formulation aid or additive in varied systems.
