Product
description:
Chitosan is a linear polysaccharide composed
of randomly distributed β-(**4)-linked D-glucosamine (deacetylated
unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by
treating shrimp and other crustacean shells with the alkali sodium
hydroxide.
Chitosan has a number of commercial and
possible biomedical uses. It can be used in agriculture as a seed
treatment and biopesticide, helping plants to fight off fungal
infections. In winemaking it can be used as a fining agent, also
helping to prevent spoilage. In industry, it can be used in a
self-healing polyurethane paint coating. In medicine, it may be
useful in bandages to reduce bleeding and as an antibacterial
agent; it can also be used to help deliver drugs through the
skin.
More controversially, chitosan has been
asserted to have use in limiting fat absorption, which would make
it useful for dieting, but there is evidence against
this.
Other uses of chitosan that have been
researched include use as a soluble dietary
fiber.

Agriculture
Grade
1. In agriculture, chitosan is typically
used as a natural seed treatment and plant growth enhancer, and as
an ecologically friendly biopesticide substance that boosts the
innate ability of plants to defend themselves against fungal
infections.
2. As feed additives, can inhibit and kill
the harmful bacterium, improve animals
immunity.
Industrial
Grade
1. Chitosan has good adsorption
characteristics of heavy metal ion, applied in treatment of organic
wastewater, dye wastewater, water purification and textile
industry.
2. Chitosan can be also applied in
paper-making industry, improving the dry and wet strength of paper
and surface printability.
Water Soluble
Grade
Water soluble grade Chitosan is transformed
from chitosan through carboxylation, freely soluble in water and
the character is stable. It has excellent moisture absorption,
moisture retention, opsonization, bacteria inhibition, etc.
Applicable to various cosmetics, such as emollient cream, shower
gel, cleaning cream, mousse, advanced ointment frost, emulsion and
colloid cosmetics, etc. Also applicable to moisturizing and
antistaling agent for food, fruits and vegetables, flocculant for
sewage treatment, drug sustained release agent, nontoxic adhesive,
auxiliaries for dyeing& printing and paper making,
etc.
Carboxymethyl
Chitosan
Carboxymethyl Chitosan is the higher
ramification of chitosan, which have **0% water solubility, film
forming ability, heavy metal chelation. It has been applied in
advanced cosmetics, heavy metal chelating agent, drug sustained
release agent, plant growth regulator agent , wastewater treatment,
etc.
