The rest of the evacuees have tested negative for the coronavirus. Pyridine-2,6-dicarbohydrazide manufacturer The KCDC said a 28-year-old man had tested positive. He was among the 368 repatriated South Koreans who arrived from Wuhan on a charter flight on January 31. The rest of the evacuees have tested negative for the coronavirus. Pyridine-2,6-dicarbohydrazide supplier We found over half the products we tested contained elevated fluorine levels,” Bruton said.
The cosmetic categories that had the highest percentage of 213 high fluorine products were foundations (63%), eye products (58%), mascaras (47%), and lip products (55%), the study found.
Even more concerning was that cosmetics containing high levels of fluorine more often than not failed to disclose any PFAS chemicals on their labels, Bruton noted.
Further analysis of 29 cosmetics with high fluorine levels revealed that they contained between four and 13 specific PFAS chemicals, researchers found. However, only 1 of the 29 products listed PFAS as an ingredient on the product label.
“Even if a consumer is doing their due diligence and trying to avoid harmful chemicals by reading labels, our work is showing that these harmful chemicals are often not disclosed,” Bruton said.
Despite this, Bruton recommends that consumers who want to limit their exposure to PFAS read the labels anyway, to at least avoid products where the chemicals are accurately listed.
High levels of fluorine were frequently found in products advertised as “long-lasting” and “wear-resistant,” which could provide another clue for discerning consumers.
But in the end, there’s not much consumers can do to solve the problem.
“It’s important that the government step up to regulate ingredients in cosmetics with more stringency,” Bruton said. “It’s also time the cosmetics industry steps up and begins efforts to move away from this class of chemicals.
