A naturally derived biomaterial formulation for improved menstrual care

Adequately managing menstruation is an important factor for the overall quality of life for women. With a growing discussion of the global need for improved menstrual health and hygiene, it is clear that better management of menstruation can positively influence social, educational, and professional outcomes. Herein, we describe a biopolymer-based formulation that gels blood in a mechanism alternative to coagulation. We first tested several biopolymer mixtures with blood and quantified increases in viscosity, identifying that high-molecular-weight alginate in combination with glycerol could rapidly absorb blood. We then demonstrated that this powder could be deployed as both a traditional menstrual pad filler and as an additive to menstrual cups to reduce leakage and spillage, respectively. Finally, we include an antimicrobial polymer to impair the growth of Staphylococcus aureus, a bacterium associated with toxic shock syndrome. Collectively, our work describes a biodegradable formulation derived from renewable resources, that can improve menstrual care.
