INCI Name(USA): Carboxymethyl chitosan

CAS No.: 83512-85-0


Introduction

Carboxymethyl Chitosan (CMC) is one salt of the biopolymer chitosan, and chitosan is a natural biopolymer modified from chitin, which is the main structural component of squid pens, cell walls of some fungi and shrimp and crab shells.


Carboxymethyl Chitosan (CMC) has wide range of new and exciting applications. It has been employed as flocculant agent for water treatment, as bactericide and fungicide in agriculture, as preservative in alimentary formulation, etc. Additionally, Carboxymethyl Chitosan has demonstrated to be a promising material for biomedical applications such as controlled drug release, enzyme immobilization for biosensor preparation, gene therapy, etc.

Application

1)Carboxymethyl Chitosan can regulate crops, such as increasing germination percentage, plant height, increasing single plant weight, and root length and leaf area. Increase crop yield, such as wheat, rice, corn, soybeans and other food crops, can improve the production of cucumber, cabbage, tomatoes, potatoes and other vegetables.

2)Carboxymethyl Chitosan can improve the quality of the crop chitosan can obviously increase the protein content of the crop, in addition, can increase the content of vitamin C, soluble total sugar, reduce the crude fiber content. It can be seen that the use of chitosan to improve the nutritional quality of crops, so that their nutrition is richer, the value of higher goods.

3)Carboxymethyl Chitosan can inhibit the growth of pathogenic bacteria, improve the antibacterial activity of crops and resist pests and diseases. The results showed that chitosan can inhibit the spore germination and growth of plant pathogenic fungi, and induce the protective function of pathogen infection, so chitosan could restrain the growth of pathogenic bacteria in the plant.
