Carboxymethyl-chitin (CMCh) is an anionic
polysaccharide and a chemical modification of chitin
that provides an alternative to improve the
biopolymer s water solubility. The chemical
structure of CM-chitin, a natural polymer, is very
close to that of mucopolysaccharides (heparin and
hyaluronic acid), whose biological tolerance has
been demonstrated for a long time. In addition, it
is an efficient trapper of heavy metals that are
responsible for very many contact allergies;
therefore it is really interesting for skin
allergies. CM-chitin is a particularly effective
hydrating agent. It has two advantages: it supplies
water and it avoids dehydration to get better on
gloss, stiffness and stickiness
