“Imagine dropping a salt shaker on the floor and then having to clean it up one individual salt crystal at a time,” describes Cosmetics Business. “Now imagine having to do the same after spilling it into the ocean, but instead of salt, which dissolves, the pieces are microplastic [plastic pieces smaller than 5mm]. The same size, but never dissolves.”
Glitter is a microplastic. Comprised of petroleum-based plastic coated in aluminum that persists in the environment for centuries, it coats ocean floors and feeds fish. Allure quoted Dr. Sherri Mason, Professor of Chemistry at SUNY Fredonia, calling glitter “a little poison pill.”
But Racked reports that perhaps glitter does not have to be bad for the planet after all.
