The main application of carboxymethyl starch (CMS)(2)

6. Daily chemical industrial grade sodium carboxymethyl starch

Sodium carboxymethyl starch (CMS) is a modified starch etherified with carboxymethyl. Which is better than carboxymethyl cellulose (CMC), and is the best product to replace CMC. CMS has the functions of chelation, ion exchange, and polycation flocculation, and can be used as a stabilizer, fiber finishing agent, and stain-carrying agent in detergent formulations. Its descaling effect is obviously better than CMC, and its pollution diffusion ability is excellent. In particular, it has excellent anti-soil redeposition effect on hydrophobic synthetic fiber fabrics.
In the cosmetic industry, CMS is used as a water-fixing or water-absorbing and water-retaining glue for the manufacture of anti-acne pharmaceutical preparations and the manufacture of skin cleansers.
In toothpaste, CMS can form a three-dimensional polymeric network structure, which can ensure the storage stability of the paste in the tube and prolong the shelf life. Improves paste uniformity and surface finish. Reduce paste delivery power. CMS is easily biodegradable, safe and environmentally friendly.

7. Petroleum industrial grade sodium carboxymethyl starch

Sodium carboxymethyl starch (CMS) is a modified starch etherified with carboxymethyl. Which is better than carboxymethyl cellulose (CMC), and is the best product to replace CMC. The aqueous solution of CMS is stable and has excellent performance, and has functions such as bonding, thickening, water retention, emulsification, suspension, and dispersion. CMS is used as a mud stabilizer and water retention agent during oil well operations to reduce water loss and improve the coalescence stability of clay particles in drilling fluid.
CMS has little effect on the plastic viscosity of the mud, but has a great effect on the power and shear force, which is beneficial to carry cuttings. Especially when drilling salt and gypsum layers, it can stabilize the drilling fluid, reduce the loss and prevent the well wall from collapsing. It is especially suitable for saline-alkali wells with high salinity and high PH value.

8. Printing and dyeing industrial grade sodium carboxymethyl starch

Sodium carboxymethyl starch (CMS) is a modified starch etherified with carboxymethyl. Which is better than carboxymethyl cellulose (CMC), and is the best product to replace CMC. The aqueous solution of CMS is stable and has excellent performance. And it has functions such as bonding, thickening, water retention, emulsification, suspension, and dispersion. The raw material of CMS is starch, which has wide sources and low price.
CMS for printing and dyeing is used as carrier paste for dyes and printing and dyeing auxiliaries, which has the advantages of good compatibility and stability. Dyeing pastes formulated with CMS are also very permeable. Especially for fabrics that require deep and transparent printing. The pattern can be printed quickly according to the layout. And the vividness of the printing can be significantly improved. In addition, CMS can be dissolved in cold water, which is convenient to use.
