　　9. Characteristic Applications: Super disintegrant, high-efficiency disintegrant, suspending agent.

　　Sodium Carboxymethyl StarchMain Uses:

　　I. Food Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch (CMS) is a modified starch carboxymethyl etherified. It is tasteless, non-toxic, resistant to mildew, and easily soluble in water. When applied to different foods, it exhibits various functions such as thickening, suspending, emulsifying, stabilizing, shaping, film-forming, puffing, preserving, acid resistance, and health benefits, with performance superior to carboxymethyl cellulose (CMC), making it a better substitute for CMC. Food-grade sodium carboxymethyl starch is widely used in milk, beverages, frozen foods, fast foods, pastries, syrups, and other products. In addition, CMS is physiologically inert and has no caloric value, so it can also achieve ideal results when used to manufacture low-calorie foods.

　　II. Pharmaceutical Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch (CMS) has a wide range of applications in pharmaceuticals. In terms of drug formulations, CMS can replace gelatin as a raw material for making capsules, tablets, and sugar coatings. It has strong water absorption and swelling properties, and can swell quickly in cold water. After absorbing water, the particles swell without dissolving, and do not form a colloidal solution, which does not hinder the further penetration of water and affect the further disintegration of tablets. Therefore, it can be used as a high-efficiency disintegrant and excipient for tablets of both insoluble and soluble drugs.

　　III. Papermaking GradeSodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch carboxymethyl etherified, with performance superior to carboxymethyl cellulose, making it a better substitute for CMC. CMS has a wide range of applications in papermaking. When added to fillers as a stabilizer, it plays a thickening and binding role, making the paper bright and glossy, improving the printability of the paper, and enhancing the toughness and wear resistance of the paper. Used as an in-pulp additive to improve retention and filtration efficiency. It is also used for surface sizing of paper, which can significantly improve the dry and wet strength, oil resistance, ink absorbency, and water resistance of the paper. Use in coating bonding can improve the production and use performance of paper.

　　IV. Construction Industry Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch carboxymethyl etherified, with performance superior to carboxymethyl cellulose, making it a better substitute for CMC. Its solution has good thickening, stabilizing, water retention, film-forming, and suspending effects. It is easy to use and environmentally friendly. It has been widely used in the building materials industry. In putty powder and latex paint, it acts as a thickening and water-retaining agent; in coatings, it acts as a suspending agent, stabilizer, and film-forming agent, with emulsification, thickening, and anti-sedimentation effects. Made into cement adhesive powder and applied to cement plaster mortar, cement heat-insulating crack-resistant mortar, tile adhesive, exterior waterproof putty, and other products related to cement.

　　V. Ceramic Industry GradeSodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch carboxymethyl etherified, with performance superior to carboxymethyl cellulose, making it a better substitute for CMC. In the ceramic industry, CMS serves as a shaping agent, plasticizer, and reinforcing agent for blanks. It can increase the bonding strength of the blanks, making the blanks easy to shape, increase the bending strength by several times, and effectively reduce the breakage rate of the blanks; it can also make the moisture in the blanks evaporate evenly, preventing drying and cracking. Added to glaze slurry as a stabilizer and binder, it can enhance the bonding between the blank and the glaze, keep the glaze in a dispersed state, increase the surface tension of the glaze, increase the smoothness of the glaze surface, and reduce the pinhole phenomenon after firing.

　　VI. Daily Chemical Industry Grade Sodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch carboxymethyl etherified, with performance superior to carboxymethyl cellulose, making it a better substitute for CMC. CMS has chelating, ion exchange, and polycation flocculation functions and can be used as a stabilizer, fiber finishing agent, and soil carrier in detergent formulations. Its descaling effect is significantly better than CMC, its soil dispersion capacity is excellent, especially its anti-redeposition effect on hydrophobic synthetic fiber fabrics is excellent. In the cosmetics industry, CMS is used as a water-retaining or water-absorbing colloid, used in the manufacture of anti-acne drug formulations and skin cleansers. In toothpaste, CMS can form a three-dimensional polymer network structure, which can ensure the storage stability of the paste in the tube, extend the shelf life; improve the uniformity and surface finish of the paste; and reduce the conveying power of the paste. CMS is easily biodegradable and environmentally friendly.

　　VII. Petroleum Industry GradeSodium Carboxymethyl Starch

　　Sodium carboxymethyl starch is a modified starch carboxymethyl etherified, with superior performance to carboxymethyl cellulose, making it a better alternative to CMC. The aqueous solution of CMS is stable and performs well, possessing functions such as binding, thickening, water retention, emulsification, suspension, and dispersion. In oil well operations, CMS serves as a mud stabilizer and water retention agent, reducing water loss and improving the flocculation stability of clay particles in drilling fluid. CMS has little effect on the plastic viscosity of the mud, but significantly affects the dynamic and shear forces, facilitating the carrying of cuttings, especially when drilling salt formations. It stabilizes drilling fluid, reduces loss, and prevents wellbore collapse. It is particularly suitable for high mineralization and high-pH saline-alkali wells.

　　VIII. Printing and Dyeing Industry Grade Sodium Carboxymethyl Starch

　　Sodium Carboxymethyl StarchSodium carboxymethyl starch is a modified starch carboxymethyl etherified, with superior performance to carboxymethyl cellulose, making it a better alternative to CMC. The aqueous solution of CMS is stable and performs well, possessing functions such as binding, thickening, water retention, emulsification, suspension, and dispersion. The raw material of CMS is starch, widely available and inexpensive. In printing and dyeing, CMS serves as a carrier paste for dyes and printing auxiliaries, offering good compatibility and stability. The dyeing paste prepared using CMS also has good permeability, especially for fabrics requiring deep and thorough penetration, allowing for quick printing of patterns according to the plate design and significantly improving the brightness of the print. In addition, CMS dissolves in cold water, making it easy to use.
