A recent study by the University of the Free State (UFS) has found endocrine-disrupting chemicals (EDCs) in every sanitary product tested, sparking nationwide concern and calls for greater transparency from manufacturers.
Deon Visser, head of the UFS’s Department of Chemistry, said the findings were consistent with international research. “Our literature review showed that these chemicals are commonly found worldwide. While product designs differ, manufacturing processes are largely similar,” Visser explained.
Visser highlighted that the main concern is long-term exposure. “The vaginal area is highly absorbent, far more so than ordinary skin, and women are exposed to similar chemicals through shampoos, conditioners, mascara, and other personal care products. It is almost impossible to measure the total daily exposure, given this cocktail of chemicals,” he said.
Cumulative exposure occurs when chemicals accumulate in the body over time, potentially increasing health risks. Visser noted that the concentrations detected in South African products align with international findings, indicating no unique regulatory gap locally.
Despite this, Visser sees an opportunity for change. He advocates revisiting acceptable chemical levels, enforcing clearer labelling of all ingredients, and encouraging manufacturers to phase out harmful substances entirely.
