JOHANNESBURG - The National Consumer Commission says further investigation is needed to validate findings around sanitary products by the University of the Free State’s Microbiology Department.
The study revealed that certain sanitary products sold in South Africa contain hormone-disrupting chemicals.
Researchers tested 16 popular sanitary pad and pantyliner brands and detected substances known to interfere with the body’s endocrine (hormone) system.

Deon Visser, Head of Chemistry at the University of the Free State, said chemicals including phthalates, parabens and bisphenols mimic hormones in the body.
“They look very similar to hormones in the endocrine system and mimic them in the body,” Visser explained.
He added that these substances are not unique to menstrual products and are commonly found in perfumes, plastics and other personal care items.

According to Visser, they are used as plasticisers, antibacterials, preservatives and stabilisers.
What is estrogen?
Estrogen is a group of primary female sex hormones produced mainly by the ovaries, with smaller amounts from fat cells and adrenal glands. It plays a key role in regulating the menstrual cycle and supporting reproductive, bone, cardiovascular and brain health.
Visser said the body may struggle to distinguish between natural hormones and synthetic chemical mimics.

“They unfortunately are in these products, and it’s all over the world. It’s not just a South African problem,” he said.
The National Consumer Commission says broader testing will now be conducted across menstrual products to ensure consumer safety before any potential recalls are considered.
Visser recommended silicone-based menstrual cups and reusable sanitary pads as possible alternatives but noted that proper sterilisation is essential.
“The silicone-based cups work well. The problem is that you need a microwave oven and clean water to clean them, otherwise you are looking at trouble again,” he said.
