The California Office of Environmental Health Hazard Assessment (OEHHA) has announced that bisphenol S (BPS) will be classified as a reproductive toxin under California Proposition 65.

Recently, the California Office of Environmental Health Hazard Assessment (OEHHA) announced that bisphenol S (BPS) will be classified as a reproductive toxin under California Proposition 65.

 

California Proposition 65, also known as Prop 65, is a legislative measure aimed at informing consumers that certain chemicals may pose potential health risks. The full name is the California Safe Drinking Water and Toxic Substances Enforcement Act of 1986, which requires all products containing chemicals that may have adverse effects on health to be clearly labeled, especially those that may cause cancer or reproductive health problems. OEHHA, as the main agency implementing the proposal, is responsible for evaluating the relevant chemicals, while DARTIC provides necessary advice and assistance.

 

BPS is usually a substitute for Bisphenol A (BPS), which is a component of polyethersulfone plastics and a synthetic fiber used in the manufacture of hard plastic items and clothing textiles. It is also used as a color developer for thermosensitive paper and as a protective coating for some food cans. BPS can even be detected in personal care products, food, baby bottles, and other products.
According to data from the US Environmental Protection Agency (EPA) and the European Chemical Administration (ECHA), the total amount of BPS produced in the US each year ranges from 1 million to 10 million pounds, while at least 10000 tons of BPS are manufactured or imported into Europe each year.

 

Research has shown that BPS can be rapidly absorbed through the mouth and skin, and is widely distributed in the human body. Although it does not accumulate in tissues or blood, it will be metabolized in the liver after absorption. It is reported that it has been detected in human blood, amniotic fluid, breast milk, skin, and urine.

 

Although BPS was once considered a safe alternative to BPA, increasing research has shown that it has a wide range of harmful effects on the neuroendocrine function of animals. DARTIC's research has found that the level of harm of BPS to the reproductive system is comparable to that of BPA, and even at lower doses, it may cause damage to female oocytes.

 

The inclusion of BPS in California's Proposition 65 list of reproductive toxins marks an important step for the state in protecting public health and the environment. This decision not only enhances the warning effect on consumers, but also drives manufacturers to seek safer alternative products.
