Sodium Carboxymethyl Cellulose
Since 1962, we are noted amongst the pioneer manufacturers and suppliers of quality Sodium Carboxymethyl Cellulose. Our compounds are formulated using high quality ingredients as per set industry standards. Sodium Carboxymethyl Cellulose is white or slightly yellowish in color and used across various industries like pharmaceutical, food, iron & steel etc. Our carboxymethyl cellulose is used in ice-creams and is also an important constituent of non food products like toothpaste, laxatives, diet pills & detergents.
Further Details :
Sodium Carboxymethyl Cellulose is the sodium salt of carboxymethyl cellulose which is formed by the reaction of highly pure alpha cellulose powder, caustic soda lye and ethanol media to first form alkali cellulose and then react with Monochloroacetic acid under controlled conditions to form CMC.
CMC Solution :
- Effect of pH : Viscosity of Sodium CMC Solution shows maximum viscosity at pH 7.0-9.0 above pH 9.0 viscosity start decreasing and below pH 4.0 free acid of CMC formed.
- Effect of Temperature : Viscosity of CMC decreases as the temperature of solution increases, but does not affect original viscosity, provided solution is not heated for longer hours at High Temperature 90°C and above.
- Effect with Salts :- The effect of salts depend upon
i) Concentration of salt
ii) pH of solution
iii) D.S of CMC
iv) Manner of Addition
a) High D.S. CMC are more tolerant to salts than low D.S.
b) Addition of salt to a sodium CMC solution increases the tolerance of salt, where as addition of salt and CMC simultaneously will reduce salt tolerance.
Sodium CMC solution is prone to bacterial and chemical attack. When sodium CMC solution is stored, a preservative should be added to prevent viscosity reduction.
