ECHA classifies Benzophenone-3 as endocrine disruptor
The classification highlights the need to balance the benefits of UV protection with the health and ecological risks associated with the use of BP-3.
EUROPE – The European Chemicals Agency (ECHA) has named benzophenone-3 (BP-3), also known as oxybenzone, as an endocrine disruptor for both human health and environmental safety based on a comprehensive decade-long evaluation that began in 2014.
This classification is due to BP-3’s ability to interfere with hormonal systems, confirmed by toxicological, reproductive toxicity, and mechanistic studies.
BP-3 is commonly used as a UV filter in sunscreens and other personal care products, valued for its protective properties against ultraviolet radiation.
However, extensive research has demonstrated that BP-3 and its metabolite, benzophenone-1 (BP-1), are absorbed through the skin, metabolised, and excreted in urine, indicating systemic exposure in humans.
Studies in animal models revealed that BP-3 alters hormonal cycles, reduces sperm concentrations, and causes developmental effects in offspring.
In humans, BP-3 exposure has been linked with menstrual cycle hormonal alterations, increased risk of uterine fibroids, and endometriosis, demonstrating estrogenic activity at relevant concentrations.
ECHA’s findings also highlight environmental risks, where BP-3 and its metabolites disrupt endocrine systems in aquatic life such as fish and invertebrates, leading to reproductive and developmental harm.
The classification under the EU Classification, Labelling and Packaging (CLP) regulation is expected to be proposed by Denmark in 2026, which would likely lead to stricter regulatory controls on cosmetic products containing BP-3.
Industry and consumers may see reforms in product formulations and enhanced risk management practices.
Regulatory pressure on BP-3 is part of a broader scrutiny of UV filters and endocrine-disrupting chemicals in cosmetics, reflecting growing concerns about safety and environmental impact.
ECHA updates on PFAS restriction plan beyond beauty and cosmetics
The European Chemicals Agency (ECHA) recently revised its approach to restricting per- and polyfluoroalkyl substances (PFAS), excluding eight sectors from detailed evaluations, a move that has sparked debate.
The decision, announced in August 2025, affects industries like printing, sealing, machinery, explosives, military, technical textiles, broader industrial uses, and medical applications.
According to ECHA, time constraints prevent its Risk Assessment (RAC) and Socio-Economic Analysis (SEAC) committees from conducting sector-specific assessments for these areas.
An ECHA spokesperson stated that the committees will focus on 14 original sectors, including food contact materials, packaging, and cosmetics, as well as PFAS manufacturing.
