| [ Microplastics](https://global-standards.org/javascript:void(0)) | Based on the working definition of ECHA: ‘Microplastic’ means a particle containing solid polymer, to which additives or other Substances may have Microplastics been added, and where ≥ 1% w/w of particles have all dimensions 1nm ≤ x ≤ 5 mm, or a length of 3nm ≤ x ≤ 15 mm and length to diameter ratio of &gt; 3. Natural polymers that have not been chemically modified are excluded, as are polymers that are (bio)degradable or have a water solubility &gt; 2 g/L. <https://echa.europa.eu/documents/10162/b56c6c7e-02fb-68a4-da69> 0bcbd504212b |
