Dr. Marcus L. Renfield is a formulation chemist with over 15 years of hands-on experience in the research and development of industrial and household cleaning agents. He earned his Ph.D. in Applied Chemical Sciences with a specialization in surfactant chemistry and solvent systems used in commercial cleaners, degreasers, and disinfectants. At Active Ingredient Hub, Marcus focuses on breaking down the chemistry behind everyday cleaning products—from alkaline builders and chelating agents to antimicrobial actives—so both professionals and informed consumers can understand what truly works and why. His writing combines lab-tested insights with real-world application, making complex formulations easier to grasp without oversimplifying the science. Outside the lab, Marcus enjoys woodworking, restoring vintage tools, and experimenting with eco-friendly DIY cleaning formulations in his home workshop. He’s also an avid cyclist and often tests “real-life cleaning performance” after muddy weekend rides.
