Sodium 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.
The chemical name of SCMS is SODIUM SALT OF CARBOXYMETHYL ETHER OF STARCH

APPLICATIONS
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.
