A French study has revealed that reducing exposure to potentially harmful chemicals found in everyday personal care products can lead to a measurable decrease in those substances within just one week.
Researchers in Grenoble conducted an experiment involving over 100 women aged 18 to 30. Participants surrendered their usual makeup, shampoo, soap, toothpaste, deodorant, and lip balm, and were provided with “clean” alternatives – products formulated without hormone-disrupting ingredients.
Urine analyses conducted after one week showed an overall reduction of approximately 20–40% in several suspect substances. Specifically, levels of bisphenol A (BPA) decreased by 39%, according to the study published in Environment International.
BPA, a commonly used plastic component, has been linked to hormone disruption and potential adverse effects on fertility. The Voedingscentrum notes associations between BPA exposure and conditions like obesity, ADHD, diabetes, and prostate cancer, although a direct causal link remains unconfirmed. The Netherlands’ RIVM institute is also investigating whether even low concentrations of BPA could pose health risks.
While BPA is already prohibited in baby bottles in Europe and its use in food packaging is being restricted, regulations concerning its presence in cosmetic and hygiene product packaging are less stringent. Researchers, including Claire Philippat, point out that BPA can enter cosmetics through contamination during production or via packaging, rather than being a deliberate ingredient.
Nicolas Jovanovic emphasized that the rapid reduction in chemical exposure is encouraging for public health. The study also estimates that if pregnant women avoid cosmetics containing hormone disruptors, their children could have approximately a 4% lower risk of developing asthma, potentially leading to societal healthcare cost savings of around €9.7 million annually.
These findings highlight the potential impact of everyday product choices on individual and public health, and could inform future recommendations regarding cosmetic and personal care product formulations.
