Millions of women across South Africa reach for basic hygiene products every month, relying on the implicit promise that these items are rigorously tested and safe. As independent testing reveals the potential presence of endocrine-disrupting chemicals in widely used sanitary pads and tampons, that trust is fracturing. While the Department of Health maintains that current levels fall within acceptable international safety limits, reproductive health activists argue that the regulatory framework is fundamentally opaque, lacking the localized, transparent oversight necessary to protect a vulnerable population from long-term chemical exposure.

This mounting controversy is not merely about consumer health it is a battle over the transparency of the South African Health Products Regulatory Authority (SAHPRA) and the manufacturers who operate within a largely self-regulated ecosystem. At stake are the reproductive health outcomes of millions of women and the integrity of a supply chain that has historically been exempt from the rigorous scrutiny applied to pharmaceuticals or food items. With activists demanding mandatory ingredient disclosure and public access to safety data, the South African government finds itself under pressure to prove that the products deemed essential for dignity are not, in fact, silently compromising public health.

The Anatomy of a Regulatory Vacuum

The core of the activist grievance lies in the disparity between the classification of sanitary products and the risk they pose. Unlike pharmaceuticals, which undergo exhaustive clinical review by the Department of Health before reaching pharmacy shelves, sanitary pads and tampons are often categorized as general consumer goods. This classification historically exempted them from the comprehensive ingredient disclosure requirements that apply to other health-adjacent products.

Public health advocates argue that the transdermal absorption of chemicals in the vaginal environment is significantly higher than that of the skin on other parts of the body, yet regulatory agencies have been slow to adapt their testing frameworks to this reality. Experts at the Reproductive Health Research Institute in Johannesburg note that without a centralized database of materials and chemical additives, it is impossible for independent scientists to conduct longitudinal studies on the cumulative impact of these products on South African women. The current government stance—that products meet international ISO standards—is criticized by activists as a reliance on outdated metrics that do not account for modern chemical manufacturing processes.

The Chemistry of Concern

Activists are specifically targeting the presence of volatile organic compounds (VOCs) and phthalates, which are often utilized in the manufacturing of absorbent polymers and plastic backings for sanitary products. According to data from independent environmental toxicology reports published in late 2025, several of the most common brands on the South African market contained traces of chemicals linked to hormonal disruption.

The following categories of additives are at the center of the dispute:

• Phthalates: Often used as plasticizers to increase the flexibility of tampon applicators linked to endocrine system disruption.
• Per- and Polyfluoroalkyl Substances (PFAS): Frequently used for moisture-wicking properties these 'forever chemicals' are known to persist in the human body.
• Dioxins and Furans: Byproducts of the chlorine bleaching process used to whiten cotton while levels have been reduced globally, activists argue that historical standards are insufficient for chronic, monthly exposure.
• Synthetic Fragrances: Often contain undisclosed mixtures of chemicals that can trigger allergic reactions and chronic inflammation.

The Nairobi Perspective: A Continental Ripple Effect

The debate in South Africa serves as a critical mirror for the East African region. In Kenya, the push for menstrual equity has centered on the removal of taxes to make products affordable, a policy success that has significantly expanded access. However, the conversation in Nairobi is now shifting toward the next logical step: quality assurance. The Kenya Bureau of Standards (KEBS) currently holds strict mandates on the physical dimensions and absorbency of sanitary towels, but, much like their South African counterparts, the regulatory focus has historically been on efficacy rather than chemical composition.

If South Africa, as a leading continental economy, shifts its regulatory framework to require full ingredient transparency, it would likely set a benchmark for the rest of the continent. Economists suggest that any new regulatory barriers—such as mandatory laboratory testing for imported products—could temporarily affect the market, which is valued at approximately USD 60 million (roughly KES 7.8 billion) in Kenya alone. However, the long-term public health savings from preventing endocrine-related reproductive issues could vastly outweigh the initial compliance costs for manufacturers.

The Path to Transparency

The impasse between the Department of Health and civil society organizations appears to be hardening. Government spokespeople have reiterated in recent press briefings that no evidence exists to suggest an immediate health crisis, urging the public to avoid panic. Conversely, the coalition of activists led by gender-based rights groups has threatened to initiate a class-action demand for an audit of all top-selling sanitary brands. They are not merely asking for reassurance they are demanding a fundamental change in how health is legislated.

As the conversation intensifies, the burden of proof is shifting. The government can no longer rely on the silence of the market to guarantee the safety of the user. Whether this leads to a mandatory labelling regime similar to that of the European Union, or a specialized testing unit within the national health regulator, the status quo is clearly unsustainable. For the millions of women relying on these products, the expectation is simple: the products that facilitate their daily participation in society should not be the reason they face health crises in the future.
