Product Description

Production description

 is a sugar obtained from the hard exoskeletons of shellfish, including crab, lobster and shrimp. It is used in medicine. Chitosan is used for high blood pressure, high cholesterol, obesity, wound healing, and other conditions, In the pharmaceutical industry, chitosan is used as a filler in tablets to improve the way certain drugs dissolve and mask bitterness Taste. It is also used to help make food last longer. Chitosan is extracted from the shells of shrimp, lobsters and crabs. It is a fibrous substance that may block the absorption of dietary fat and cholesterol. When applied to wounds, chitosan helps blood clot.

Certificatiion of Analysis

Funcation

 has good inhibitory effect on escherichia coli, pseudomonas fluorescein, Staphylococcus aureus, bacillus subtilis, etc., and can also inhibit physiological changes of fresh food. Chitosan natural non-toxic, suitable for acidic and containing less protein food preservation, polymer and ionic complex can agglutinate. For example, the antiseptic preservation of fruit, the dosage of acetic acid 0.1%+ chitosan 0.05%-0.1%. Derivatives of chitosan also have good antibacterial activity, even stronger than chitosan.

Application

1. Pharmaceutical and pharmaceutical applications

As mentioned earlier, chitosan is a biopolymer with interesting biomedical applications due to its low toxicity, biodegradability and biocompatibility. The biopolymer is readily degraded by enzymatic hydrolysis and lysozyme, a proteolytic enzyme found in all human tissues. In the same way, lipases found in the stomach, pancreatic juice or saliva can degrade chitosan. In all cases, the resulting products were non-toxic.

2. Biological materials

 has shown a wide range of applications due to its good behavior in humans, as this biopolymer has been reported to have antibacterial activity, biological activity, chemotaxis, immune stimulation, enzymatic biodegradability, mucosal adhesion or epithelial permeability, which facilitates adhesion to different types of cells . Due to this excellent performance, on the one hand, chitosan and chitin are used to treat wounds, burns and ulcers due to their hemostatic properties and accelerated wound healing effect. On the other hand, chitosan has also been used for tissue regeneration and repair due to its biodegradability and cellular affinity.

3. Agricultural application

1. The application of chitin and chitosan in agriculture mainly focuses on four directions:

2. Plants protect against disease and plague (before and after harvest).

3. Support beneficial microbial-plant symbiosis.

4. Strengthen biological control and antagonism of microorganisms.

5. Plant growth and development and regulation.

6. Chitosan has shown interesting fungicidal activity as well as antiviral and antibacterial activity against 7. many plant pathogenic fungi. In this sense, the antibacterial properties of chitosan and its excellent 8. film-making ability have been used for post-harvest preservation of fruits and vegetables, producing 9. antibacterial protection and extending shelf life

4. cosmetics

Chitosan is the only naturally occurring cationic polymer that becomes thick when neutralized by an acid. This fact, along with the static properties of fungicides and fungi, favours their use in creams, lotions, permanent wave lotions and nail polish

5. Drug delivery

The development of drugs in the clinical field is a great challenge, because most drugs fail to achieve the desired clinical effect due to their inability to reach the target site of action. A high proportion of administered drugs spread to organs and tissues that do not participate in pathological processes, leading to severe effects.

chitosan extra forte de arkopharma due to its abundant availability, inherent pharmacological properties and other biological characteristics (biodegradability, biocompatibility, avirulent spectrum or low immunogenicity) and can be used as a potential excipient of oral drug sustained release, in the human body has no side effects of chitosan can be different forms (beads, membrane, microcapsules, coating, table) suitable substrate. Membranes or films with different hydrophilic behaviors can be prepared by forming mixtures of chitosan with highly hydrophilic polymers (such as polyvinyl alcohol, polyvinylpyrrolidone or gelatin) that control swelling or by semi-interosmosis and interosmosis networks. Gelation of glutaraldehyde crosslinked chitosan has been reported to be sensitive to pH values delivered by the drug because the gel can swell and deswell over a wider pH range. Smart drug delivery systems can release them after some changes in environmental conditions (temperature, pH, electric field, light and some chemicals). This drug delivery is managed by diffusion coefficient and relaxation time, which is highly dependent on pH and drug solubility.
