Chulalongkorn University Researchers Produce Spray To Enhance Protectiveness of Masks

Report Post

A Chulalongkorn University Research Team has invented a  “Shield+ Protective Spray” to make fabric masks waterproof and can enhance the protectiveness offered by masks against viruses, and water droplets.  The spray is an alternative innovation to make fabric masks more useful for the public, especially at a time when surgical masks become more difficult to find.

The research team, consisting of Assistant Professor Dr. Jittima Luckanagul, Faculty of Pharmaceutical Sciences, and Phutthimon Sribonfah, B.Sc.Pharm, worked on innovating this spray and it was devoid of any harmful respiratory substances. The spray acts as

From preliminary performance tests, results show that applying the Shield+ Protecting Spray on a fabric mask helps cover the fabric fiber and increases the efficiency of filtering out 0.3 micron particles by 83% and the filtering out of germs in saliva and in the air by 93% and 142% respectively.

The research team also collaborated with the Startups team from the CU Innovation Hub and the university’s public and private allies, to make a production that meets GMP standard requirements. The team aims to produce and distribute up to 10,000 Shield+ Protecting Sprays, which can be applied on a total of 240,000 fabric masks for the medical support team, hospital delivery drivers, police and soldiers at the COVID-19 checkpoints, and garbage collectors.
