Hexafluoropropylene oxide dimer acid (HFPO-DA) is a member of a group of perfluorinated chemicals used in many consumer products. HFPO-DA and other perfluorinated chemicals can cause serious health effects, including cancer, endocrine disruption, accelerated puberty, liver and immune system damage, and thyroid changes. These chemicals are persistent in the environment and they accumulate in people. Click here to read more about perfluorinated chemicals.
