Scientists have warned that over time, some sunscreens can become toxic and produce a chemical that can cause cancer.
American and French scientists studied a number of brand name sun lotions that contained a chemical called octocrylene.
They found that over time, the chemical can break down and produce a compound called benozophren, which can cause skin and liver cancer.
Scientists want the chemical banned, reports The mirror.
your study was published in Chemical Research in Toxicology using branded sunscreens purchased in stores in the United States and France.
Scientists artificially aged the products.
Speaking of which to France info About the study, said Dr. Didier Stien, one of the authors: “When benzophenone is on the skin, dermatitis can develop. It can cause cancer, especially liver cancer.”
“It is a molecule that affects the thyroid function and disrupts the development of the reproductive organs.
“To our knowledge in the scientific literature and in general, nobody [before this study] had shown that octocrylene is broken down to benzophenone. “
In the study’s conclusion, scientists said, “There is enough scientific literature to argue that octocrylene / benzophenone products can pose a threat to individual and public health.
“Several jurisdictions, including the Republics of Palau and Marshall Islands and the US Virgin Islands, have banned octocrylene in sunscreens and cosmetic products with effect from January 2020.
“It is convenient that there needs to be more refined, more stringent, unbiased data on exposure and toxicity of these chemicals and the products they contain.”
According to the Cosmetic Toiletry & Perfumery Association, the new study is not intended to show that octocrylene-containing sunscreens pose a health risk to humans, only that benzophenone impurities may be present in sunscreens after manufacture.
There is a sunscreen number on the back of the package that tells how long you can use it after opening it.
