Purified Chitin

Product Name Purified Chitin Product Overview Purified Chitin is a natural basic polysaccharide polymer material prepared from natural biomass (exoskeletons of crustaceans such as shrimp shells and crab shells, and fungal cell walls) through a green and mild multi-stage purification process (demineralization, deproteinization, decolorization, water washing, and drying). Its CAS number is 1398-61-4, molecular formula is (C₆H₁₁NO₄)ₙ, and molecular weight can be precisely adjusted according to requirements. This product adopts green purification technologies such as structure-selective oxidation to completely remove calcium carbonate, protein, pigments, heavy metals and impurities from raw materials, with a purity of more than 99%. It is a white or off-white loose powder with no odor and no toxicity, and has good biocompatibility, biodegradability, chemical stability and unique cationic properties. As the only natural basic polysaccharide containing nitrogen in nature, it conforms to the concept of green, low-carbon and sustainable development, and can be widely used in various high-end fields such as biomedicine, food, environmental protection and agriculture. Product Features High Purity and No Impurities, Controllable Quality: After multi-stage green purification process, the purity is as high as 99% above,no heavy metals, pigments and toxic solvent residues, fully complying with food-grade and pharmaceutical-grade standards (such as USP, EP, GB 1886.215-2016), with high quality consistency between batches, which can meet the strict purity requirements of high-end fields. Green and Environmentally Friendly, Mild Preparation: Adopting green purification technology under normal temperature and pressure, no toxic pollutants are emitted, and lye can be neutralized, recovered and recycled, truly realizing zero-pollution production; raw materials are derived from crustacean wastes (such as shrimp shells and crab shells), realizing resource utilization of agricultural wastes, which not only solves the problem of waste disposal, but also reduces raw material costs, conforming to the global green development trend. Excellent Performance and Diversified Functions: It retains the natural biocompatibility and complete biodegradability of chitin, and the degradation products are carbon dioxide and water without environmental residues; it also has good chemical stability, film-forming property, adsorbability and cationic activity, rich in active functional groups such as -NH₂ and -OH, which can be further modified and processed to achieve multiple functional adaptations. Controllable Morphology and Strong Adaptability: The product is in the form of loose powder with good dispersibility and no obvious agglomeration. The particle size, molecular weight and morphology (such as powder, fiber, film) can be adjusted according to application needs, which can be uniformly dispersed in aqueous phase, organic phase and various matrices, facilitating subsequent processing and forming, and adapting to application scenarios in different fields. Safe and Non-Toxic, Widely Applicable: After safety testing, it is non-toxic, non-immunogenic, and harmless to human body and environment, and can be directly used in fields with high safety requirements such as food contact and biomedicine; compared with synthetic polymer materials, it has both environmental protection and safety, outstanding cost performance, and can replace some high-priced functional materials. Application Fields Biomedical Field: With excellent biocompatibility, biodegradability, hemostatic and wound-healing properties, it can be used to prepare medical dressings, tissue engineering scaffolds, drug carriers, etc.; as a drug sustained-release carrier, it can prepare microspheres, capsules and other preparations to achieve precise drug release and reduce side effects; it can also be used to prepare hemostatic sponges and wound-healing gels to accelerate wound recovery, adapting to the high-end needs of the medical field. Food Industry Field: As a food-grade functional raw material, it can be used as a food additive (thickener, stabilizer, emulsifier) in the processing of beverages, meat products, dairy products and other products to improve product taste and stability; at the same time, it can be used to prepare degradable food packaging materials and food preservation films. By virtue of its good barrier properties and antibacterial properties, it can extend the shelf life of food, replace traditional non-degradable plastic packaging, and conform to the green and safe needs of the food field. Environmental Protection Field: By virtue of its unique adsorption performance, it can be used for wastewater treatment to efficiently adsorb heavy metal ions (such as lead, arsenic) and organic pollutants in wastewater to purify water quality; it can also be used as an environmentally friendly adsorbent for air purification (such as adsorbing formaldehyde), and can also prepare degradable environmental protection films and disposable environmental protection tableware to reduce white pollution and assist environmental governance. Agricultural Field: It can be used as a soil amendment to improve soil structure and fertility, and can stimulate plant growth and induce plants to produce disease and insect resistance; it can also be used as a carrier for pesticides and fertilizers to achieve slow and controlled release, improve the utilization rate of pesticides and fertilizers, reduce environmental pollution, and adapt to the needs of green agricultural development. Cosmetics Field: As a natural skin care raw material, it has good moisturizing, antioxidant and antibacterial properties. It can be added to skin care products and cosmetics to improve skin moisture, enhance skin barrier function, and its mild and non-irritating characteristics are suitable for sensitive skin. It can be used to prepare moisturizing creams, masks, hair conditioners and other products. Other Fields: It can be used in the industrial field, such as adding to paints and inks to increase the coloring efficiency by more than 30%, enhance the gloss, crack resistance and antibacterial ability of paints; used in battery diaphragm modification to strengthen ion transport efficiency, improve diaphragm wrinkle resistance, and reduce the risk of battery short circuit; it can also be used to prepare high-performance fibers, flexible electronic device substrate materials, etc., expanding the application boundary of new green functional materials.
