Nanoplastics are extremely small plastic particles, typically less than 100 nanometers in size. They can be formed through the breakdown of larger plastics or can be manufactured intentionally for various applications.
Nanoplastics are used in products such as filters and some consumer goods due to their ability to trap contaminants and due to their physical properties. The health evidence regarding nanoplastics is still emerging. Some studies have raised concerns about their potential to enter biological systems and cause harm, but comprehensive assessments are not yet conclusive.
When you see nanoplastics on a label, it's important to consider the product's context, as the potential risks can vary based on usage and exposure levels.
Commonly found in: Shower Filters, Sink Filters, Home Filters
What to watch
- Some studies suggest that nanoplastics may penetrate biological membranes, but conclusive evidence is lacking.
- Uncertainty exists regarding the long-term impact of nanoplastics on human health and the environment.
There are no specific regulations or GRAS status for nanoplastics, and usage is monitored cautiously.
Research is ongoing, with mixed findings about the health impacts of nanoplastics and their environmental persistence.
Nanoplastics are not derived from animals and are typically considered vegan-friendly.
