Hand Sanitizer Gels from Sustainable Resources for Various Skin Types

Web Published:

Developing sustainable approaches to produce consumer materials is one of the promising routes to effectively reduce carbon footprint. During unpresented situations, for example COVID-19 global pandemic, consumer materials such as hand sanitizer gels become strategic products with a global high demand. Current technologies in producing such gels require at least 5 components and may go up to 10 in some cases. In addition, due to the usage of these petroleum-based components, the formulation and production process of hand sanitizer gels becomes inflexible and limited to small scale productions

Researchers at Princeton University have invented a novel formulation to produce green hand sanitizer gels that can kill 99.9% of germs on bare hands, leaving no sticky solid residues. The invention offers a sustainable yet scalable production process to produce hand sanitizer gels for any regional or global demands. Moreover, we offer special formulations for hand sanitizer gels that incorporates recommended ingredients for moisturizing different skin types (dry, normal, oily, and sensitive).


  • 99.9% effective in killing germs on bare hands
  • Special formulation that incorporates recommended ingredients for moisturizing different skin types



  • Green and Sustainable product – reduce carbon footprint
  • Biocompatible ingredients
  • Facile and cost-effective production process
  • Leaves no sticky residue on hands

Rodney Priestley is a Professor of Chemical and Biological Engineering, Vice Dean for Innovation and Associate Director for Princeton Center for Complex Materials. Professor Priestley has published nearly 100 articles, edited a book, and is co-inventor on four patent-pending technologies in the area of drug-delivery and polymer colloids, substances that make up gels and emulsions. His research group is focused on understanding how materials that undergo changes in their properties and join together when confined in tiny spaces open new possibilities for a vast range of novel applications, including drug delivery, designer colloids and sustainable manufacturing. Prof. Priestley is engaged in three industry-university research collaborations in the areas of pharmaceuticals and cosmetics as well as polymer nanocomposite design, and is the co-founder of two companies that are working to translate University intellectual property into technologies or products. Prof. Priestley joined Princeton as an assistant professor in 2009, after completing a postdoctoral fellowship at École Supérieure de Physique et de Chimie Industrielles in Paris. He received his Ph.D. in chemical engineering in 2008 from Northwestern University and his B.S. in Chemical Engineering from Texas Tech University in 2003.


Sujit Datta is an Assistant Professor of Chemical and Biological Engineering at Princeton University. He is also an Associated Faculty at the Andlinger Center for Energy and the Environment and the Princeton Institute for the Science and Technology of Materials. He earned a BA in Mathematics and Physics and an MS in Physics in 2008 from the University of Pennsylvania, where he studied nanomaterials like graphene and carbon nanotubes with Charlie Johnson. He earned his PhD in Physics in 2013 from Harvard, where he studied fluid dynamics and instabilities in porous media and colloidal microcapsules with David Weitz. His postdoctoral training was in Chemical Engineering at Caltech, where he studied the biophysics of the gut with Rustem Ismagilov. He joined Princeton in 2017, where his lab seeks to understand and control the behavior of soft materials in complex settings, motivated by applications like oil/gas recovery, water remediation, carbon sequestration, and drug delivery. Prof. Datta is the recipient of the LeRoy Apker Award for outstanding achievements in Physics, the Andreas Acrivos Award in Fluid Dynamics from the American Physical Society, the Alfred Rheinstein Faculty Award, and the ACS Petroleum Research Fund New Investigator Award.


Navid Bizmark is a PCCM Postdoctoral Research Fellow with Prof. Rodney Priestly. Dr. Bizmark recently earned his Ph.D. from the University of Waterloo, Canada, where he worked with Professor Marios Ioannidis' group. As a PCCM Postdoctoral Research Fellow, Navid is working with Professor Rodney Priestley focusing on generating Pickering emulsions with structured colloids and hybrid polymer/inorganic nanostructured systems.
