Your toothpaste may be full of plastic.
Earlier this year, Phoenix dental hygienist Trish Walraven began noticing tiny blue dots trapped in the spaces between the teeth and gums of her patients.
The saddest part? Polyethylene microbeads are FDA-approved as a food additive.
"It is used primarily for containers and packaging… and has been a concern for the environment because polyethylene lasts practically forever and isn’t biodegradable," said Walraven. “It only breaks down into smaller and smaller particles until you can’t see it anymore.”
"According to Crest: Polyethylene plastic is in your toothpaste for decorative purposes only," wrote Walraven at the time. "This is unacceptable not only to me, but to many, many hygienists nationwide. We are informing our patients. We are doing research separately and comparing notes. And until Procter & Gamble [which manufactures Crest toothpaste] gives us a better reason as to why there is plastic in your toothpaste, we would like you to consider discontinuing the use of these products."
Walraven may get her wish. New York and California had already moved in February to ban beauty products with microbeads due to health concerns, but Procter & Gamble, announced Wednesday that the company is making major changes to several of its products following national attention to Walraven's post.
“While the ingredient in question is … part of an enjoyable brushing experience for millions of consumers with no issues, we understand there is a growing preference for us to remove this ingredient,” company officials told ABC7 Detroit in a statement. “So we will.”
Unilever and Colgate-Palmolive have joined P&G in a pledge to start phasing microbeads out of their products. P&G says all of their products will be microbead-free by March 2016.
