Tiny plastic microbeads have been used in beauty products, toothpaste and even home cleaning products for years as an abrasive for skin, teeth and surfaces. But the problem with these tiny beads is that when they are washed down the shower drain, they are not biodegradable, and they end up ingested by aquatic wildlife. Since the ingredients list for personal care products do not need to warn about microbeads, it can be impossible for consumers to tell what products contain them. The nonprofit North Sea Foundation has created an app called "Warning! Plastics Inside!" where you can scan any product and it will tell if it contains microbeads. Download the app for any smartphone for free.
