Pharmaceutical Grade Chitosan Water soluble 90% /100% Chitin
Quick Detail :
Water-Soluble Chitosan is off-white or yellowish, transparent and
amorphous semitransparent solid. Easily soluble in water. The
solution is clear and character is stable
Water-Solubility Chitosan(Acet-Chitosan Sodium) is prepared by the
acetylation of chitosan that is extracted from shell of Alaska Crab
.It is soluble in water ,and has an excellent functions of moist
CPCTS absorbing ,wet keeping , regulating, and bacteria inhibiting
etc. It is widely used in the following fields: cosmetics,food,
fruit water Keeping and preservation, flocculation of waste water,
relaxation agent of drugs, no toxic adhesive,textile and dyeing,
and paper assistant preparation etc.
1. Chitosan contains amido and carboxyl, and has excellent film
forming performance. Thus, it can be applied in water resistance of
2. Chitosan is a linetype substance of high molecular weight, and
has enough bonding strength and linkage function among fibers, so
it can be used as intensifier and retention aid.
The molecular weight and chemical structure of chitosan is similar
to that of fibrin. It shows positive electricity in water solution,
with certain cation performance, excellent membrane forming
performance, good penetration and stable water resistance. Chitosan
suitable for sizing agent of paper.
3. Chitosan is also a kind of preservative in paper making
4. Chitosan, compounded with glutin, polyol and polyacid etc.,can
be produced into compound sizing agent. The special-purpose paper
made with chitosan can be applied in offset printing, absorbing
both water and ink.
5. Capacitor paper, treated with 0.3%-2% chitosan HAC solution, can
greatly improve electrical resistivity.
6. At present the widest application of chitosan is intensifier and
retention aid in paper making industry. Ideal intensifier should be
of the following conditions:
① Of linear macro molecule, enabling the amido in close proximity
to the fiber surface.
② Of comparatively large molecular mass and film forming capacity,
enough fiber bonding strength and linking capacity among fibers.
③ There are many centers of positive charge and carboxyl on the
molecular chain, convenient for electrostatic bonding.
Off-white flake or powder
5. Competitive Advantage :
