What is Carboxymethyl Starch CMS

 

Carboxymethyl starch is an anionic starch ether with the chemical formula of [c10h19o8na]n, white or yellow powder, and an electrolyte soluble in cold water. It is a kind of modified starch and belongs to ether starch. It is a water-soluble anionic polymer compound. It is tasteless, non-toxic, not easy to mildew, and soluble in water when the degree of substitution is greater than 0.2. CMS has stable aqueous solution and excellent performance, with the functions of bonding, thickening, water retention, emulsification, suspension and dispersion. As a mud stabilizer and water retaining agent during oil well operation, CMS can reduce water loss and improve the coalescence stability of clay particles in drilling fluid. CMS has little influence on the plastic viscosity of the mud, and has a great influence on the power and shear force. It is conducive to carrying drilling cuttings. Especially when drilling the salt gypsum layer, CMS can stabilize the drilling fluid, reduce the loss and prevent the collapse of the well wall. It is especially suitable for saline alkali wells with high salinity and high pH value.

Working Principle of Carboxymethyl Starch CMS
 

Sodium carboxymethyl starch (CMS or SCMS) is a starch ether derivative derived from starch. It is soluble in water at room temperature and forms a transparent to light milky and viscous solution.


CMS is an important modified starch with unique properties due to the presence of negatively charged functional group (CH2COO-). The introduction of carboxymethyl groups interrupts the ordered structure of native starch and intervenes with the re-association of gelatinized starch. This modification yields starch with decreased gelatinization temperature, increased solubility and improved storage stability.


CMS is chemically processed carbohydrate typically derived from native starch viz. Maize, potato, tapioca & rice.
These sodium carboxy methyl starch and solution are alkaline in nature and have the capacity to replace sodium car-boxy methyl cellulose in fields like textile sizing and printing, corrugated paper, paper sizing, oil well drilling, water based distemper, oil bound distemper, electrodes, ceramics, pesticides, foundry, adhesives and others.


CMS has a wide range of applications in industries, mostly used for purposes of thickening, stabilization, water preserving, etc. In pharmaceutical industry, CMS, also known as sodium starch glycolate, is commonly used as disintegrate. It is also used in textile industry as thickening agent in textile printing paste and as sizing agent especially for hydrophilic yarn.


Another closed related material is carboxymethyl cellulose (CMC), which has been used intensively in similar industries. However, CMS not only has many advantages over CMC, but comes with a much lower price tag. Therefore, CMS is poising to replace CMC in many of industrial applications.


CMS are widely used in oil well drilling, textile, paper & corrugated board, detergent, welding electrodes, food, pharmaceutical, pesticides, cosmetic, toothpaste, paint, mining and ceramic industries.

Carboxymethyl Starch CMS as a Reducing and Capping Agent

 

 

The hydrothermal method is a cost-effective and eco-friendly route for preparing various nanomaterials. It can use a capping agent, such as a polysaccharide, to govern and define the nanoparticle morphology. Elemental selenium nanostructures (spheres and rods) were synthesized and stabilized using a tailor-made carboxymethyl starch (CMS, degree of substitution = 0.3) under hydrothermal conditions. CMS is particularly convenient because it acts simultaneously as the capping and reducing agent, as verified by several analytical techniques, while the reaction relies entirely on green solvents. When submersed into the water, the subsequent particle release was confirmed by dynamic light scattering (DLS), promising great potential for use in bio-three-dimensional printing and other biomedical applications.

 

Polysaccharides are promising candidates for various fields, including material science, medicine and biotechnology, due to their biodegradability, renewability and versatility. They consist of amylose and amylopectin chains. Starch is poorly soluble in water at room temperature due to the strong hydrogen bonds of hydroxyl groups, limiting its applications in food, cosmetics, medicine, absorbents and adhesives. However, it could be chemically modified due to the three active hydroxyl positions at C2, C3 and C6. Generally, this reaction is performed in a heterogeneous medium (ethanol/water, isopropyl alcohol/water, benzene/water). The polar aprotic solvent is required for efficient etherification. DS is controlled by factors such as solvent type, NaOH and SMCA concentration, temperature and reaction time. Isopropyl alcohol aqueous solution was previously identified as the most effective solvent for CMS production, giving the best DS. The solubility in water appears already at DS of 0.1. Isopropyl alcohol/water mixture is also convenient for removing unreacted impurities from CMS.

 

CMS is particularly convenient because it acts simultaneously as the capping and reducing agent. Used CMS with a DS of 0.3 as a reducing and stabilizing agent to investigate the hydrothermal process in more detail. It explored the effect of processing parameters, such as reaction time, temperature and reagent concentration, on the nanoparticle size and morphology. The formation of selenium nanostructures was monitored via colour change (UV-visible (UV-VIS) spectroscopy), dynamic light scattering (DLS), scanning and transmission electron microscopy (SEM and TEM), Fourier transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Particular emphasis was put on anisotropic Se nanorods for their potential use in biomedical applications. On top of that, we also included an application case by embedding the Se nanoparticles into a three-dimensional-printed 2-hydroxyethyl methacrylate (HEMA) hydrogel carrier.

Synthesis Process of Carboxymethyl Starch CMS

 

_20240531165047

Carboxymethyl starch was prepared using sodium monochloroacetate, where 1 g (6 mmol) of potato starch was dispersed in 100 ml of the round bottom flask containing 50 ml of isopropyl alcohol-water mixture (9 : 1). The mixture was treated with 1 ml 10% NaOH at room temperature (RT) for 1 h to deprotonate the alcohol groups present in the monomeric units of starch (scheme 1a). The mixture was stirred for up to 5 h at RT, followed by adding a sodium monochloroacetate solution (2.096 g/18 mmol in 5 ml of distilled water) and stirring for 2 h at 50℃. After the reaction, a white solid was collected, dried at 50℃ for 14 h, and neutralized by 0.4 ml of 6 M HCl for 2 h at RT. Several filtrations with an acetone-water mixture were conducted to purify the product .


The obtained solids were weighed and used to grow selenium nanostructures using the hydrothermal technique. Initially, 0.1 g (1%) of carboxymethyl starch (DS = 0.3, pH 5–6) and 0.1 g (1%) of Na2SeO3 were dissolved in 10 ml of distilled water and placed into a Teflon-lined stainless steel autoclave. The reaction was performed at 160℃ for 14, 7 or 3 h (scheme 1b). It was then cooled to room temperature, and the solid content was separated by centrifuging and washed with ethanol. Different Se ion concentrations were obtained by varying the concentration of sodium selenite (1%, 0.5% and 0.25%).
