Unilever US and drugstore chain Rite Aid are facing a legal battle after a couple from California alleged that the Anglo-Dutch FMCG manufacturer’s Vaseline Petroleum Jelly is flammable, according to a report published by Reuters.

The lawsuit, which was filed on September 18, 2017 in the US District Court for the Central District of California, maintains that the plaintiff suffered third-degree burns in October 2016 after applying Vaseline to her skin, which then ignited.

Unilever-owned Vaseline’s US site states that ‘Vaseline Jelly is not flammable. When heated to extremely high temperatures of more than 400 degrees Fahrenheit, Vaseline Jelly may give off flammable vapors. Even in summer, this isn’t going to happen naturally.”
