What about polyethylene in toothpaste?

Polyethylene is often used as a microplastic in some toothpaste formulations, primarily as a thickening agent or for its abrasive properties. Concerns have arisen regarding its environmental impact, as these microplastics can contribute to pollution in waterways and oceans. Additionally, there are questions about the safety of ingesting small amounts of polyethylene during brushing. As a result, some consumers are seeking toothpaste alternatives that are free from microplastics.
