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 Carboxymethyl starch and solution are alkaline in nature and have the capacity to replace sodium carboxymethyl cellulose in fields like textile sizing & 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
