New Period Pads & Cups Solidify Blood To Keep The Leaks Out

For decades, menstrual hygiene products have relied on absorption to manage period flow. But what if, instead of soaking up blood, these products could solidify it? This is the intriguing concept being explored by researchers at the Virginia Polytechnic Institute and State University who are developing pads and cups that transform menstrual fluid into a gel-like state.
The idea hinges on a clever material combination to make the blood itself less prone to spills. The research team, led by biomedical scientist Bryan Hsu, is focusing on a powder mixture that leverages two readily available ingredients: alginate, a seaweed-derived polymer, and glycerol, a naturally occurring alcohol. When this powder comes into contact with menstrual blood, it triggers a chemical reaction that solidifies the fluid. This gel effectively traps the flow, preventing leaks and potentially offering a more secure and comfortable period experience.
A study published in the esteemed journal Nature highlights the promising potential of alginate-based menstrual products. The researchers compared the blood-solidifying properties of alginate to conventional absorbent materials used in pads. Their findings revealed that alginate significantly outperformed traditional fillers, particularly when it came to retaining blood at full capacity.
“We want to gel it, so that it can be managed better,” Hsu explained.

This bloody good invention extends beyond pads, with the scientists exploring the use of alginate in period cups, a reusable alternative that collects rather than absorbs menstrual fluid. Here, too, alginate demonstrated its ability to solidify the collected blood, minimizing the risk of spillage and mess—a common concern for menstrual cup users.
There is a double benefit to this concept. Both alginate and glycerol are biodegradable and already have established uses in various products, including food additives. This not only ensures the safety of these menstrual products but also bodes well for their environmental impact.
If the technology can make reusable cups more user-friendly by minimizing leaks and mess, it could be a game-changer in reducing the significant waste generated by disposable tampons and pads. By solidifying blood and minimizing leaks, these innovative menstrual products offer a promising solution for both users and the environment.
While the research is promising, it’s important to note that alginate-based menstrual products are still in the development phase. Further studies are needed to assess their long-term safety, comfort, and cost-effectiveness.
