Plastic microbeads are tiny non-biodegradable solid plastic particles. They have been added to a wide range of products including rinse-off cosmetics, personal care, and cleaning products for a variety of purposes include an abrasive or exfoliant. Why is it important to stop microbeads polluting the environment? Microbeads are not captured by most wastewater treatment systems. If they are washed down drains after use, they can end up in rivers, lakes, and oceans and can have a damaging effect on marine life, the environment and human health.
