This product is a high viscosity carboxymethylcellulose (CMC); the viscosity of a 1% solution in water at 25 oC is 1500-3000 centipoise (cps).
Is sodium carboxymethyl cellulose a viscosity modifier?
It serves as a viscosity modifier, thickener, emulsion stabilizer, and water-retention agent (Li et al. 2009). Na-CMC is also used in the production of hydrogels with biomedical applications (drug delivery, tissue engineering) (Ali et al. 2016).
How do you prepare a 0.5% CMC solution?
Measure 0.5g of dry CMC-Na and dissolved in 100 ml ddH2O/0.9% Saline (0.9 g NaCl in 100 ml ddH2O) to make a clear solution.
How do you dissolve CMC powder?
Operation method: Put CMC Powder in the container (note that the container must be dry), and fully moisten with 95% ethanol (to fully wet the CMC powder, usually 1gcmc powder plus ethanol). Then add water and stir quickly to achieve the desired result quickly.
What is the difference between CMC and sodium CMC?
The key difference between sodium CMC and CMC is that sodium CMC, or sodium carboxymethyl cellulose, is easily soluble in both hot and cold water and is easy to preserve, whereas CMC, or carboxymethyl cellulose, is poorly soluble in water and is difficult to preserve as it is.
Is carboxymethylcellulose soluble in water?
CMC is soluble in water at any temperature. Because of its highly hygroscopic nature, CMC hydrates rapidly. Rapid hydration may cause agglomeration and lump formation when the CMC powder is introduced into water.
How do you make CMC gel?
1. First, dissolve 1.05 grams of Al3+ in 350ml of water, and then gradually add 7.0 grams of CMC while agitating the solution at 10,000rpm using a Homo Mixer (mfg by PRIMIX Corporation). It is also possible to prepare this gel by putting the alum and water into a plastic bag containing CMC.
How do you make carboxymethylcellulose gel?
Add 50 ml water to 3 g carboxymethyl cellulose . Allow it to swll overnight. Add slightly more water say, 30 ml. Stirr and heat to 40-50 degree Celsious.
What is carboxymethylcellulose used for?
Generic Name: carboxymethylcellulose sodium This medication is used to relieve dry, irritated eyes. Common causes for dry eyes include wind, sun, heating/air conditioning, computer use/reading, and certain medications.
How do you mix carboxymethylcellulose?
The solubility of CMC generally depends upon the degree of substitution of CMC itself. The low DS will have lower solubility whereas higher DS will have high DS. However, you can dissolve CMC by heating water at 60 C and stirring at very high speed. I tried to put CMC in water and stir it at 4°C over-night.
Is sodium CMC soluble in water?
Is carboxymethylcellulose sodium salt?
Carboxymethylcellulose, Sodium Salt is the most often used form of cellulose gum. CMC is used in a variety of industries as a thickener and/or to prepare stable emulsions in both food and non-food products.
