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

cas number: 9063-38-1.

properties
1) white or light yellow powder.
2) insoluble in ethanol, ether, acetone and other organic solvents.
3) easily soluble in cold water, immediate intake water and swell in 15 minutes.
4) absorption of water is 30 times comparing to original volume.
5) in the presence of acid and metal salts, will produce a white turbidity or precipitation.
6) biodegradable and non-toxic.
