In a letter to GIB, LLC, FDA enforcers warned the comapany to get caucer-causing formaldehyde out of the product, or the agency will start pulling it off the shelves.
The Braziilian Blowout is marketed as "formaldehyde-free," however, the FDA letter says its tests showed dangerous levels of formaldehyde. It said methylene glycol, the liquid form of formaldehyde, ranged from 8.7% to 10.4% of the solution.
The agency says Brazilian Blowout releases formaldehyde vapor when hair treated with the product is heated with a blow dryer, and then a hot iron.
Those vapors can be a danger to salon clients and workers, according to the FDA letter.
Formaldehyde reacts with the tissues lining the respiratory tract and eyes. It can cause eye, nervous system, and breathing disorders, as well as nausea, chest pain, vomiting, and rash.
The FDA gave the company 15 days to respond to the complaint. The company says stands by its product.
