A Missouri woman was stunned recently when a bottle of dry shampoo exploded in her daughter’s car after it was left there during a hot day and blew through the sunroof before landing some 50 feet away.

Christine Debrecht of St. Louis, Missouri took to Facebook to post photos showing the damage inside her 19-year-old daughter Josie’s car.

“It was hot yesterday and the can exploded,” Christine wrote. “It blew the console cover off of its hinges, shot through the sunroof, and went high enough in the air that it landed about 50 feet away.”

“I just want to remind you (and your kids) to heed those warnings on products you may be using,” she continued. “Please don’t leave aerosol cans (and especially dry shampoo, as this seems to be an issue with some brands) in your car! I am so grateful that no one was hurt.”

The photo that Christine posted showed a green bottle of dry shampoo produced by Equate Beauty.

Equate was once an independent brand, but has since been taken over by Walmart, where it is now sold. The product’s page on Walmart’s website states that Equate’s dry shampoo contains ingredients such as propane, butane, isobutane, chloride, and phenethyl alcohol. The green bottle that Christine posted about contain a label warning of its “extremely flammable” nature.

“Container may explode if heated,” the warning on the bottle reads.

Propane and butane are chemicals that act as propellants, which means they help push out the liquids stored in an aerosol can. When they are heated, these chemicals are known to become extremely flammable.
