AlthoughSodium Carboxymethyl StarchWhile sodium carboxymethyl starch is not an antibiotic, it is a pharmaceutical ingredient. It's primarily used with various drugs and food stabilizers, maintaining puffing activity. Therefore, our body's muscles can absorb this substance. Sodium carboxymethyl starch molecules are colorless and odorless, so patients can take it with peace of mind. Furthermore, in the current textile industry, health organizations also add sodium carboxymethyl starch, which is beneficial to the human body. So what are its uses?

　　1. Food GradeSodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch made by carboxymethyl starch etherification. It is tasteless, non-toxic, mildew-proof, and easily soluble in water. When used in different foods, it has multiple functions such as thickening, suspending, emulsifying, stabilizing, shaping, film-forming, puffing, preserving freshness, acid resistance, and health benefits. Its performance is superior to carboxymethyl cellulose, making it the best substitute. Food-grade sodium carboxymethyl starch is widely used in products such as milk, beverages, frozen foods, fast food, pastries, and syrups. In addition, carboxymethyl starch is physiologically inert and has no caloric value, so it can be used to make low-calorie foods to achieve the desired effect.

　　2. Pharmaceutical Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is widely used in the pharmaceutical field. In terms of drug preparations, carboxymethyl starch can replace gelatin as a raw material for preparing capsules, tablets, and sugar coatings. It has strong water absorption and expansion properties and can swell rapidly in cold water. After water absorption, the particles swell but do not dissolve, nor do they form a colloidal solution. It does not hinder the continuous penetration of water, nor does it affect the further disintegration of the tablets. Therefore, it can be used as an effective disintegrant and excipient for both insoluble and soluble drug tablets.

　　3. Paper GradeSodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch made by carboxymethyl cellulose etherification. Its performance is superior to carboxymethyl cellulose, making it the best substitute. Carboxymethyl starch is widely used in papermaking. Added as a stabilizer to the filler, it plays a thickening and bonding role, making the paper bright, improving the printability of the paper, and enhancing the toughness and wear resistance of the paper. Used as an additive for pulp to improve retention and drainage. It can also be used for surface sizing of paper, which can significantly improve the dry strength, wet strength, oil resistance, ink absorbency, and water resistance of the paper. Its application in coating and bonding can improve the production and use performance of paper.

　　4. Construction Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch made by carboxymethyl cellulose etherification. Its performance is superior to carboxymethyl cellulose, making it the best substitute. Its solution has good thickening, stabilizing, water-retaining, film-forming, and suspending effects. It is easy to use and environmentally friendly. It has been widely used in the building materials industry. Used as a thickening and water-retaining agent in putty powder and latex paint; used as a suspending agent, stabilizer, and film-forming agent in coatings, with emulsification, thickening, and anti-settling effects. The produced cement powder is used in cement plaster mortar, cement heat-insulating crack-resistant mortar, tile adhesive, exterior wall waterproof putty, and other cement-related products.

　　5. Ceramic Industry Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch made by carboxymethyl cellulose etherification. Its performance is superior to carboxymethyl cellulose, making it the best substitute. In the ceramic industry, carboxymethyl starch is used as a shaping agent, plasticizer, and enhancer. It can increase the adhesion of the blank, making the blank easy to shape, doubling the bending strength, and effectively reducing the breakage rate of the blank; the moisture in the blank can evaporate evenly to prevent drying and cracking. Added to the glaze as a stabilizer and binder, it can enhance the binding of the glaze, keep the glaze in a dispersed state, improve the surface tension of the glaze, increase the smoothness of the glaze, and reduce pinholes after baking.

　　6. Daily Chemical Industry GradeSodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch made by carboxymethyl cellulose etherification. Its performance is superior to carboxymethyl cellulose, making it the best substitute. Carboxymethyl starch has chelation, ion exchange, and polycationic flocculation functions. It can be used as a stabilizer, fiber finishing agent, and pollution carrier in detergent formulations. Its descaling effect is significantly better than carboxymethyl cellulose, and its pollution diffusion capacity is excellent, especially for hydrophobic synthetic fiber fabrics. In the cosmetics industry, carboxymethyl starch is used as a water-retaining or water-absorbing colloid in the manufacture of anti-acne drug preparations and skin cleansers. In toothpaste, carboxymethyl starch can form a three-dimensional polymer network structure, ensuring the storage stability of the toothpaste in the tube and extending the shelf life; improving the uniformity and surface smoothness of the slurry; and reducing the transmission power of the paste. Carboxymethyl starch is easily biodegradable and environmentally friendly.

　　7. Petroleum Industry Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch made by carboxymethyl cellulose etherification. Its performance is superior to carboxymethyl cellulose, making it the best substitute. The CMS aqueous solution is stable and has excellent performance, with adhesion, thickening, water retention, emulsification, suspension, and dispersion functions. As a mud stabilizer and water retention agent in oil well operations, carboxymethyl starch plays an important role in reducing water loss and improving the aggregation stability of clay particles in drilling fluid. Carboxymethyl starch has little effect on the plastic viscosity of the mud, but a great effect on power and shear force, which is conducive to carrying rock, especially when drilling salt formations, it can stabilize the drilling fluid, reduce losses, and prevent wellbore collapse. It is particularly suitable for high-salinity, high-acid-alkali salt-alkali wells.

　　8. Printing and Dyeing Industry GradeSodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch etherified with carboxymethyl cellulose, whose performance is superior to carboxymethyl cellulose, making it the best product to replace carboxymethyl cellulose. CMS aqueous solution is stable and has excellent properties, including adhesion, thickening, water retention, emulsification, suspension, and dispersion functions. The raw material of carboxymethyl starch is starch, which is widely available and inexpensive. Carboxymethyl starch used in printing and dyeing serves as a carrier slurry for dyes and printing auxiliaries, exhibiting good compatibility and stability. The dyeing slurry prepared with CMS has good permeability, especially for deep transparent shaping of fabrics, allowing for rapid printing of patterns according to the design and significantly improving the fidelity of the print. In addition, carboxymethyl starch is soluble in cold water, making it convenient to use.
