We first learned about benzene in early 2021 when its presence in a long list of sunscreens shook the beauty industry (and pretty much all sunscreen users across the country), and recalls ensued. And unfortunately the scare didn’t stop at sunscreen. In October 2022, more than 1.5 million dry shampoo products were recalled due to traces of the chemical, which can pose some threatening risks.
So what is benzene exactly? “Benzene is a volatile chemical used in the production of a wide range of industrial products, including chemicals, dyes, detergents, and some plastics,” explains Ron McLaughlin, senior vice president of product development for Living Proof. “Benzene is formed from both natural processes, such as volcanoes, and from human activities, such as tobacco smoke, emissions from automobiles, and burning coal and oil. Unintentionally, benzene can also show up as a by-product, or impurity in what is known as ‘trace amounts in certain raw materials.”
McLaughlin continues, explaining that the majority of aerosol dry shampoos on the market utilize hydrocarbon propellent (gas) and ethanol in their products at various levels to deliver the product onto hair. “Most hydrocarbon aerosol propellant blends are made up of propane, n-butane and iso-butane, and have the potential of having benzene as an impurity due to their source materials.”
Without strict quality control measures in place, McLaughlin says both ingredients are possible pathways for low levels of benzene to make it into the final dry shampoo products. “It’s important to note that just because you see these ingredients like propane and isobutane listed on packaging does not mean that benzene has made its way into the formula. This is where strict quality controls and testing come into play. Not every brand does this thorough level of due diligence.”
At the end of the day, no one should have to worry about breathing in harmful chemicals while trying to hide greasy roots, so for now, we’re sticking to the formulas that have been tested and proven safe, like these nine dry shampoos.
