This is truly a very interesting, high commercial value technology – female hygiene products that are bio-degradeable, eco-friendly, non-cancer causing.
IIT Hyderabad has come up with an invention of biocompabible polymer matrix for female hygiene products. The conventional sanitary napkins and tampons use what are known as super-absorbent polymers (SAP) which are got from petroleum—therefore, they are not biodegradeable and could cause cancer.
IIT Hyderbad has invented a cellulose acetata-based, electrospun nano fibres which is significantly higher absorbent in all the uses.
Use of electrospun CA nanofibers in place of micron size fabric in commercial female sanitary napkins not only enhances the absorption properties, mechanical strength and remarkably reduces residual percentage but also eliminates the use of SAP’ without compromising its performance. This in turn may pave the way to resolve many health and environmental issues related with the use non-biodegradable SAP.
IIT Hyderabad has put out plenty of scientific information. Check it out in this URL: https://patents.google.com/patent/WO2016016704A2/en
The IIT had called for Expression of Interest for buying this technology. The last date for it is over, but interested parties may reach out to them to see if it is still available.
