Product Details

What is Source of 99% chitosan ?

Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-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 Graden 

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. 

 

Application:

Water Soluble Grade of Chitosan
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 100% 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.
