Similarly, limited evidence points to BHT’s ability to mimic estrogen, raising concerns about its impact on hormonal balance and overall endocrine health.
Links to Cancer
The International Agency for Research on Cancer (IARC) classifies BHA as a possible human carcinogen. Experimental studies have shown that dietary exposure to BHA can lead to the development of benign and malignant tumors in animals. While human epidemiological data are inadequate to conclusively link BHA to cancer, the presence of BHA in a variety of consumer products, including cosmetics, warrants caution and further investigation.
Impact on Aging and Skin Health
While BHA and BHT are effective in preserving the shelf life of cosmetics, they can also induce allergic reactions in the skin. These reactions can range from mild irritation to more severe dermatological conditions, potentially exacerbating the aging process and compromising skin health. The potential for these preservatives to bioaccumulate in aquatic organisms also raises questions about their long-term impact on human skin when absorbed from cosmetic products.
Other Reported Health Risks
Aside from the risks mentioned above, BHA and BHT have been associated with a variety of other health concerns. High doses of BHT have been found to be toxic in mice and rats, causing issues with liver, thyroid, and kidney function, as well as affecting lung function and blood coagulation. The potential for these effects to translate to humans, particularly through long-term exposure, is a significant concern. Additionally, BHA is listed as a chemical of potential concern under the Convention for the Protection of the Marine Environment of the North-East Atlantic, due to its toxicity to aquatic life and potential for bioaccumulation.
