Product Description

Chitosan Acetate

Common chitosan is insoluble in water and organic solvents. It can only be dissolved in some dilute inorganic acids and organic acids, which limits its application to a great extent.
Chitosan acetate improves the solubility of chitosan, and maintains the polymer properties of chitosan, which makes its application more convenient and more extensive.


Carboxymethyl Chitosan

Carboxymethyl chitosan is an important derivative of chitosan. Compared with chitosan, carboxymethyl chitosan has the advantages of being able to dissolve in neutral and weakly alkaline environment and has stable properties.
Carboxymethyl chitosan has excellent hygroscopic and moisturizing properties and can be used in cosmetics and other fields.
Main technical indicators:
Appearance: Like white to light yellow powder
Degree of substitution: >60%
Moisture <10%
Water soluble >99%
Pb < 2 PPM
As < 1 PPM
Packing: 25kg/ barrel



Chitosan nitrate

Appearance: Raw white powder, highly soluble in water, PH3-5.
Product features: Good water solubility, high nitrogen content.
Application: raw material intermediates, agriculture, fertilizer and other specialized fields. Products are mainly supplied to foreign markets and a small amount of domestic markets.
Use environment: neutral, weak acid, acid
Packing specification: 25kg/ barrel


Chitosan lactate

Product properties: White to light yellow solid powder, easily soluble in water, insoluble in high concentration of ethanol, ace tone and other organic solvents. The aqueous solution is colorless or light yellow clear transparent solution with stable physical and chemical properties. The molecular structure of the product contains abundant -hydroxyl group, which is easy to bind water molecules, and has good water absorption and water retention performance.
Uses: Chitosan lactate has good biocompatibility, excellent bacteriostatic performance, moisturizing performance, health care function, but also has other potential special uses, can be used in dressings, sanitary materials, biochemistry, health food, functional food, tobacco additives, food additives, raw material intermediates and other fields.
Our advantages: chitosan lactate is produced with natural raw materials and auxiliary materials, and the production process does not contact with other chemical synthetic raw materials, so the product is more natural and safe. Chitosan lactate products produced by our company have been exported to North America, Europe, Japan and South Korea and other developed countries for nearly ten years, and the indicators of the products fully meet the requirements of international standards.

High viscosity chitosan (high molecular weight chitosan)

High viscosity chitosan is also known as high molecular weight chitosan, the product is produced by a specific process, its viscosity, high molecular weight, good solubility, can be used in food, cigarette adhesives, textile fibers, gels, biomedical materials, flocculating clarifying agent, and other industries with special uses.

The high viscosity chitosan produced by our company is produced by our company's proprietary technology. Compared with the traditional process products, it has the advantages of good appearance quality, apparent viscosity, long molecular chain segment, high molecular weight, superior solubility and high clarity of the solution. It avoids the shortcomings of high viscosity chitosan produced by traditional process, such as insufficient dissolution, high acid insoluble substance and poor solution transparency.
Over the years, the high viscosity chitosan produced by our company has been exported to Japan, South Korea, the United States, the Netherlands and other countries, and has been well received by users, and also undertakes the processing business of the products from abroad.

High density chitosan

High density chitosan, also known as high density chitin, has a higher packing density than conventional chitosan and is suitable for application in the field of health food.
Generally speaking, the packing density of powdered chitosan is usually 0.15-0.30g/ml, which is relatively low. The weight of filling chitosan is low for capsules of the same volume.
Our company adopts mature technology and process means, according to the needs of customers, can produce 0.3-0.5g/ml of medium density chitosan, and 0.5-0.7g/ml of high density chitosan, to meet the health products and other industries of capsule filling or tablet requirements.
The density of high-density chitosan is 2-3 times that of conventional chitosan, and its adsorption capacity of oil is more than 3 times that of conventional chitosan at the same volume. Generally, only 1 capsule is used each time, which can quickly dissolve under the condition of stomach acid in a short time, and absorb a large number of oil, cholesterol and chloride ions. Flocculation is produced in the alkaline environment of intestinal tract and is directly discharged from the body. To achieve the goal of losing weight, lowering blood lipid and controlling blood pressure.

Product advantage
Our company all uses high quality raw materials to produce high density chitosan, advanced product process, good appearance of products, heavy metal index and microbial index control strictly, internal quality index is better than general products.
We can adjust the density of products according to customer requirements, so as to facilitate the capsule filling process requirements of the health product industry. At the same time, the company can according to customer requirements for capsule filling basic experiment, provide the necessary reference data. The company can provide chitosan with different packing densities of 0.10-0.30g/ml, 0.30-0.5g/ml, 0.5-0.7g/ml and so on.
