BLOEMFONTEIN - A study by the University of the Free State has revealed a hidden health risk in everyday menstrual products, including some marketed as chemical-free.
Researchers tested 16 popular sanitary pad and pantyliner brands and found substances known to interfere with the body’s hormone system.
Deon Visser, Head of Chemistry at the University of the Free State, said the chemicals -- including phthalates, parabens, and bisphenols -- mimic hormones in the endocrine system.
“They look very much or very similar to the hormones in the endocrine system and they mimic them in the body,” Visser explained.
He added that these harmful substances are not unique to menstrual products, but are also found in perfumes, plastics, and other personal care items.
“They disrupt the hormonal system in a female's body. They are found in a lot of personal care products, not just sanitary pads. The harmful chemicals can also be found in perfumes and plastics.”
According to Visser, the chemicals are used as plasticisers, antibacterials, preservatives, and stabilisers in these products.
“They unfortunately are in these products, and it’s all over the world. It's not just a South African problem,” he said.
Visser recommended silicone-based menstrual cups and reusable sanitary pads as safer options.
"There are different products on the market. The silicone-based cups, work well. The problem is that you need a microwave oven and clean water to clean them or else you are looking at trouble again.”
He added that a multidisciplinary team at the university -- including chemists, social scientists, and microbiologists -- is working on developing sanitary towels with antibacterial properties as a safer option for women.
