South African Study Detects Endocrine Disruptors in 16 Menstrual Pad Brands
Research from the University of the Free State identifies hormone-disrupting chemicals in sanitary pads and panty liners, prompting calls for regulatory review of menstrual product safety standards across the continent.

Researchers at the University of the Free State in South Africa have identified endocrine-disrupting chemicals in 16 brands of sanitary pads and panty liners, raising questions about the safety of menstrual products used by millions of women across the continent.
The study examined commercially available menstrual products for the presence of chemicals capable of interfering with hormonal systems. Endocrine-disrupting compounds can mimic or block natural hormones, potentially affecting reproductive health, metabolism, and developmental processes. Women of reproductive age face particular exposure risks given the prolonged contact of these products with mucous membranes.
Chemical Detection and Health Implications
According to findings reported by SABC News, the University of the Free State research team detected hormone-disrupting substances across multiple product brands currently on the market. The study has sparked debate within South Africa's public health community about existing safety standards for menstrual hygiene products.
Endocrine disruptors represent a class of chemicals that can interfere with the body's hormonal balance even at low concentrations. Common sources include certain plastics, pesticides, and industrial compounds. When present in products that maintain direct contact with genital tissue for extended periods, absorption rates may exceed those of chemicals encountered through other exposure routes.
The mucous membranes of the vaginal area demonstrate higher permeability than ordinary skin, potentially increasing systemic absorption of any chemicals present in menstrual products. This anatomical consideration amplifies concerns about chronic exposure over years of product use.
Regulatory Gaps and Product Testing
Most African countries lack specific regulatory frameworks governing the chemical composition of menstrual hygiene products. Unlike pharmaceuticals or food additives, sanitary pads typically face minimal pre-market safety testing requirements. Manufacturers generally classify these items as personal care products rather than medical devices, subjecting them to less stringent oversight.
The South African research emerges amid growing global scrutiny of menstrual product safety. Studies in Europe and North America have previously identified various chemicals of concern in sanitary pads, including phthalates, volatile organic compounds, and dioxins formed during bleaching processes.
As reported by Bulawayo24, the University of the Free State findings highlight what researchers describe as a "hidden health risk in everyday menstrual products." The detection of endocrine-disrupting chemicals in commonly used brands suggests widespread exposure among South African women, with potential implications for markets throughout the Southern African Development Community region where similar products circulate.
Development of Safer Alternatives
In response to their findings, the University of the Free State has announced plans to develop safer sanitary pad alternatives, according to SABC News. This initiative reflects a broader movement toward creating menstrual products free from potentially harmful chemicals while maintaining affordability and accessibility.
The research institution's commitment to developing alternative products addresses both safety concerns and practical market needs. In many African countries, menstrual hygiene product costs already strain household budgets, with studies showing that between 15% and 30% of women face period poverty—the inability to afford adequate menstrual supplies.
Any new products must balance chemical safety with cost considerations to ensure accessibility. Premium organic or chemical-free menstrual products currently available in some markets often carry price points that place them beyond reach for average consumers in developing economies.
Public Health Response
The study's publication creates pressure on national health authorities to establish testing protocols and safety standards for menstrual hygiene products. South Africa's National Department of Health has not yet issued formal guidance in response to the research findings.
Public health experts note that comprehensive risk assessment requires additional research to quantify actual exposure levels and establish dose-response relationships for the detected chemicals. The presence of endocrine disruptors does not automatically indicate harm at the concentrations found, though the precautionary principle suggests minimizing exposure to such compounds, particularly among vulnerable populations.
Women's health advocates across the region have called for transparency in menstrual product manufacturing, including mandatory disclosure of chemical constituents. Such requirements would enable informed consumer choice and facilitate epidemiological research into potential health effects.
The University of the Free State research adds to mounting evidence that everyday consumer products may contain chemicals with biological activity at levels previously considered negligible. As testing methodologies improve and detection limits decrease, regulatory frameworks will need updating to reflect current scientific understanding of low-dose chemical exposures and their cumulative effects on human health.
