Researchers in the Indian Institute of Technology (IIT) Hyderabad have developed their own hand sanitizer, in line with the standards recommended by World Health Organization (WHO) and Centers for Disease Control (CDC), a Federal Health Agency in the US, for the institute community.

Around ten liters of hand sanitizer have already been deployed on the campus for the benefit of the students, staff and faculty at locations such as faculty lounge, Shiru Cafe, meeting halls and laboratories, among other areas.

This makes it more likely that people will use it and this will help stop the spread of germs and promote good health and hygiene. This has been developed by Dr Shivakalyani Adepu, who was a Research Scholar at the Department of Materials Science and Metallurgical Engineering, IIT Hyderabad along with Dr Mudrika Khandelwal, Associate Professor, Department of Materials Science and Metallurgical Engineering, IIT Hyderabad, a statement here said on Wednesday.

Speaking about their effort, Dr Mudrika Khandelwal said, "My research group has always believed in doing scientific research and outreach for the benefit of society. This is our small contribution at the time of need.

I am glad we would make this happen and hope to make similar contributions in the future." The composition of this hand sanitizer is 70 per cent isopropanol with glycerol, polypropylene glycol to increase the viscosity and reduce the volatility so that the sanitizer stays on the skin to allow the action, as well as lemongrass oil for antimicrobial activity and therapeutic aroma.

The 70 per cent IPA solution penetrates the cell wall, coagulates all proteins, and therefore the microorganism dies. According to WHO and CDC, hands account for transmitting nearly 80 per cent of the infections due to frequent touching of eyes, nose, mouth and ears which leads to the entry of germs. Nearly one in five people do not regularly wash their hands.

Of those who do, 70 per cent do not use soap. The alcohol-based hand sanitizers kill most bacteria, and fungi, and stop some viruses, present on hands within 30 seconds of application, the statement added.
