Commentary:

Chitosan is a partially deacetylated polymer of N-acetyl glucosamine. The
molecular weight varies from 10,000 to more than 1,000, 000 daltons. The mole
fraction of deacetylated units, defined as the degree of deacetylation, is usually
from 70% to 90%. In acidic conditions, the deacetylated amino groups are protonized
to formhigh positive charge densities and make the chitosan soluble in water.
As a result, chitosan is usually dissolved in a diluted, weak acid, such as acetic acid,
citric acid or lactic acid.
Chitosan possesses moisturizing ability, film-forming ability and ability to control flow
characteristics, and these properties are useful in a variety of cosmetic applications.
Apart from the cosmetic applications, chitosan has found widespread application as a
fat absorber in the health food industry.
