Businesses must notify Californians about significant exposures to chemicals that cause cancer, birth defects, or other reproductive damage in accordance with Proposition 65. When products are purchased or utilized, exposure to these chemicals may occur. In California, exposure can also happen at home, at work, or in other settings. Proposition 65 empowers Californians to make knowledgeable decisions regarding their exposure to harmful chemicals by mandating the provision of this information.
Additionally, Proposition 65 forbids California companies from intentionally releasing large quantities of specified contaminants into drinking water sources.
California must publish a list of chemicals known to cause cancer, birth defects, or other reproductive harm in accordance with Proposition 65. Originally released in 1987, this list needs to be updated at least annually. There are currently more than 900 compounds in it.
Voters in California passed Proposition 65 by a vote of 63 to 37 in November 1986, making it a law. The Safe Drinking Water and Toxic Enforcement Act of 1986 is the statutory name for Proposition 65.
What types of chemicals are on the Proposition 65 list?
Numerous manmade and naturally occurring compounds are on the list because they can cause cancer, harm to the reproductive system, or both. These compounds include substances or additions found in food, medications, colors, solvents, everyday home items, and insecticides. Listed chemicals can also be byproducts of chemical processes, like motor vehicle exhaust, or they can be utilized in manufacturing and construction.
Recently added chemical to PROP 65 & its impacts
The list of substances that are covered by Proposition 65 is constantly changing. Bisphenol S (BPS) and vinyl acetate are two noteworthy substances that have been added to the list as of 2025. These latest developments emphasize how important it is for consumers and businesses to continue to be aware of environmental and public health hazards.
1. Vinyl acetate (Cas No.- 108-05-4): What Is It, and Why Is It a Concern?
One of the key chemicals added to the Proposition 65 list in early 2025 is vinyl acetate, a compound recognized as a carcinogen. This substance is widely used in the production of polymers and copolymers, such as ethylene vinyl acetate (EVA), which is commonly found in products like solar panels, wire insulation, and adhesives.
Vinyl acetate is used in a variety of applications where flexibility, durability, and insulating properties are needed. For example, EVA plays a crucial role in the solar industry by providing encapsulation for solar cells, thus increasing their durability and efficiency. EVA is also found in items like sports equipment, footwear, and coatings.
However, prolonged exposure to vinyl acetate has been linked to an increased risk of cancer, particularly for workers in industries where the chemical is present in high concentrations, such as manufacturing facilities.
2. Bisphenol S (BPS) (CAS No- 80-09-1): A Potential Reproductive Hazard
Bisphenol S (BPS) has also been added to the list because of its known harm to male reproductive systems. Products that claim to be BPA-free now use BPS, a chemical used in the manufacture of plastics and epoxy resins, as a substitute for bisphenol A (BPA).
BPS was formerly believed to be a safer alternative to BPA, but new research has shown that it has endocrine-disrupting qualities that may impact the reproductive system, especially in men. Thermal paper receipts, plastics, and even some personal care items frequently contain BPS.
Proposition 65’s listing of BPS emphasizes the continued worry about substances that mimic natural hormones and their potential to interfere with physiological processes.

Implications for Businesses and Consumers
These compounds’ inclusion on the Proposition 65 list is an important reminder of the possible health concerns associated with common environmental contaminants. Businesses will be subject to more regulatory scrutiny and the requirement for greater openness on the chemicals used in products because of these developments, especially those in manufacturing, retail, and product development.
According to California law, companies must give customers “clear and reasonable warnings” regarding their exposure to substances on the Proposition 65 list. As a result, businesses that produce, market, or transport goods that include vinyl acetate, bisphenol S, or other compounds on the list are required to warn consumers through labels, signs, or notifications.
Customers can use the labels or warnings as a guide to help them make better judgments regarding the goods they purchase. It’s crucial to remember that a product’s inclusion on Proposition 65 list does not always indicate that it is dangerous; rather, the legislation only mandates that consumers be informed when they may be exposed to a chemical at levels higher than those considered safe.
Vinyl acetate and bisphenol S are two more substances underscoring the critical role of Proposition 65 in safeguarding consumer safety and public health. As the list of regulated chemicals continues to evolve, both businesses and consumers must stay vigilant and informed about the potential risks linked to the products they use and the chemicals they encounter daily.

FAQs:
1. What are the new chemicals added to the Proposition 65 list in 2025?
Bisphenol S (BPS) (CAS No- 80-09-1) & Vinyl acetate (Cas No.- 108-05-4)
2. What is Vinyl Acetate and why is it a concern?
Vinyl acetate (CAS No. 108-05-4) is a chemical widely used in the production of ethylene vinyl acetate (EVA), which is found in products like solar panels, adhesives, and wire insulation. Prolonged exposure to vinyl acetate has been linked to an increased risk of cancer, particularly among workers in manufacturing industries. Its inclusion in Proposition 65 list helps raise awareness about the risks associated with this chemical
3.What is Bisphenol S (BPS) and why is it harmful?
Bisphenol S (CAS No. 80-09-1) is a chemical commonly used as a substitute for bisphenol A (BPA) in BPA-free products. It is used in the production of plastics and epoxy resins. Recent research has shown that BPS has endocrine-disrupting properties and may interfere with reproductive health, particularly in males. It is found in products like thermal paper receipts, plastics, and some personal care items.
