Media misconceptions augment uncertainty
The wipes also might poseenvironmental risks,because they’re made fromplastics and syntheticcellulosic fibers, some ofwhich arenon-degradable....

Ongoing issue: industry misconception
…Key requirements for any standardinclude that the product: … does notcontain plastic or regenerated celluloseand only contains materials which willreadily degrade in a range of naturalenvironments.

Federal Trade Commission definition for “Rayon” fiber:
A manufactured fiber composed of regenerated cellulose, in which substituents havereplaced not more than 15% of the hydrogens of the hydroxyl groups. Lyocell isclassified as a sub-category under “Rayon”.

Biodegradability is break down of aproduct by microorganisms intocarbon dioxide and water, so that itcan be consumed by the environment[EN 14046 (2003) or ISO 14855(2005)].
Lenzing™ fibers are completely biodegradable in soil
