Product introduction：
Carboxymethyl dextran is a polymer formed by chemical reaction of glucose molecules, and each glucose unit has a carboxymethyl group (–-CH2COOH). The introduction of carboxymethyl gives carboxymethyl dextran many special chemical and physical properties, such as water solubility, biocompatibility and versatility. Usually exists in the form of its sodium salt. As a natural polysaccharide existing in yeast cell wall, its special molecular structure enables it to specifically activate immune cells of the body, and bind with specific receptors on the surface of Langerhans cells to activate Langerhans cells and induce their immune and repair functions. So as to enhance the immune function of the body, which is called "immune polysaccharide". The product has the functions of moisturizing, repairing skin and preventing ultraviolet damage. It is completely water-soluble, especially beneficial to skin absorption.
Structural characteristics of carboxymethyl dextran：
Glucose unit: Carboxymethyl glucan is composed of multiple glucose units connected by glycosidic bonds. Glucose is a six-carbon sugar, which plays the role of the basic structural unit in carboxymethyl dextran.
Carboxymethyl: Each glucose unit is connected with a carboxymethyl group (–ch2cooh), which is the named source of carboxymethyl dextran. The introduction of carboxymethyl gives carboxymethyl dextran many special chemical and physical properties.
Hydroxyl group: In addition to carboxymethyl group, there are hydroxyl groups (–Oh) on the glucose unit, which make carboxymethyl dextran have good water solubility.
Multifunctional: Carboxymethyl Glucan is multifunctional, and different properties and functions can be achieved by adjusting the preparation method and structural changes. For example, the solubility, viscosity and drug release performance of carboxymethyl dextran can be adjusted by changing the number and position of carboxymethyl.
Natural sources: carboxymethyl dextran is usually extracted from marine organisms, such as algae and crustaceans. This makes carboxymethyl dextran have good biocompatibility and biodegradability.
Preparation method of carboxymethyl dextran：
Material preparation: prepare glucose and formaldehyde as raw materials. Glucose can be extracted from natural sources (such as algae or plants), while formaldehyde can be used in industrial production.
Optimization of reaction conditions: according to the properties and application requirements of carboxymethyl dextran, the reaction conditions were optimized. This includes the adjustment of reaction temperature, reaction time, raw material ratio and pH value.
Reaction process:
A. Dissolve glucose: dissolve glucose in an appropriate solvent, such as water or organic solvent.
B, adding formaldehyde: gradually adding formaldehyde into the glucose solution, and fully stirring and mixing during the reaction.
C. Adjusting reaction conditions: According to requirements, parameters such as reaction temperature, pH value and reaction time can be adjusted during the reaction to control the structure and properties of products.
D, completion of the reaction: after continuing the reaction for a period of time, the formation of carboxymethyl dextran will reach a balance. After the reaction, the product is separated by an appropriate method (such as filtration or centrifugation).
Purification and treatment: The carboxymethyl glucan obtained by separation may contain other impurities, which need to be purified and treated. Common purification methods include solvent precipitation, gel filtration and ion exchange. These steps can help to remove unreacted raw materials and secondary products, thus obtaining carboxymethyl dextran with high purity.
Function of carboxymethyl dextran：
Biocompatibility: carboxymethyl dextran is a polysaccharide extracted from natural sources (such as algae or crustaceans), which is not easy to cause immune response in human body, so it is widely used in medicine. It can be used as sustained-release agent, biological scaffold, tissue engineering and skin repair.
Curing agent: carboxymethyl dextran can form a cross-linked network with other compounds, which makes it have excellent mechanical strength and spatial stability. This curing agent has excellent durability and high efficiency, so it can be used in coatings, adhesives and paper.
Adhesive: carboxymethyl dextran can be used as a biological adhesive to keep medical devices in the right position and promote tissue healing. It can also be used in the fields of paper processing and wood products.
Drug sustained release: Carboxymethyl dextran can achieve drug sustained release by adjusting its structure and solubility. It can be used for oral and topical drugs to prolong the action time of drugs and reduce side effects.
Environmental protection: carboxymethyl dextran is widely used in water treatment and soil remediation. It can be used for adsorption, filtration and separation to remove environmental pollutants and improve environmental conditions.
In which fields can it be applied?
Medical field: it can be used as a carrier of drug sustained-release system to control the release of drugs to improve the therapeutic effect. In addition, carboxymethyl dextran also has antibacterial, hemostatic and wound healing activities, which makes it have potential clinical application value in wound dressing, bone tissue engineering and regenerative medicine.
Food field: Because of its stability and thickening, it is often used as food additive, such as thickener, emulsifier and stabilizer. In addition, carboxymethyl dextran can also enhance the texture of food, improve the taste and prolong the shelf life.
Cosmetic field: It can be used as a natural humectant and antioxidant, which helps to improve the moisture content of skin and prevent free radical damage. In addition, carboxymethyl dextran can also provide soft texture and good lubricity, making it a common ingredient in cosmetics.
Environmental field: Because of its biodegradability and biocompatibility, it can be used to purify wastewater and treat pollutants. In addition, the adsorption properties of carboxymethyl dextran make it an effective adsorption material for heavy metal ions and organic pollutants.
Material field: carboxymethyl dextran can be used as coating, adhesive, paper and wood products. It can be used as an important component of curing agent, biological adhesive and durable material.
