Knicks do not contain
harmful chemicals.
All the polymers we use are water-based and are approved by global regulations
(no detergents). The main polymer is Vytex which is natural and
hypo-allergenic. The fibers are made of viscose (a fibre derived from natural
sources).Vytex is biodegradable—for
two reasons: because of natural oxidization and chemical reaction to the
environment, and because relatively common bacteria and fungi are able to
break  it down for use over their life
cycles.
