9781984945020Plain-language summary of each regulated substance found above, drawn from public regulatory data.
17-beta-Estradiol is a natural form of the hormone estrogen, often simply called estradiol. It is used in hormone replacement therapy, birth control pills, and some cancer treatments. This substance is also found naturally in the body. California's Proposition 65 lists 17-beta-Estradiol because it is classified as a carcinogen, meaning it has been linked to cancer in scientific studies. The listing does not mean that everyday exposure is dangerous, but it requires businesses to inform Californians about significant exposures. The California Office of Environmental Health Hazard Assessment (OEHHA) manages this list to help people make informed choices. This summary draws on public regulatory data; the linked source is authoritative.
