The difference between Sodium CMC and CMC

Sodium CMC spell is very similar with CMC, but it is absolutely a different material. Many customers can’t distinguish these two products well. How to differ these two products, let’s introduce briefly here.

1. Frame difference:

    The full name of Sodium CMC is Sodium Carboxymethyl Cellulose(CMC), its formula frame has negative charge.

    It’s one kind of cellulose derivates and made from natural cellulose after reaction of alkaline, etherification process. It’s a kind of sodium salts.

    The full name of CMC is Carboxymethyl Cellulose, its formula doesn’t have charge. It’s a kind of cellulosic acids obtained by removing sodium ions from Carboxymethyl Cellulose, it is also called cellulose gum. Definitely, we can find Carboxymethyl Cellulose(CMC) in Sodium Carboxymethyl Cellulose(SCMC), which is the sodium salt form of CMC.

    2. Property difference:

     Sodium CMC can be dissolved in hot and cool water easily but CMC can’t be dissolved in water. Normally, Sodium CMC has high viscosity compared to CMC. And there are more than 80 types of Sodium CMC based on different viscosity range, purity and D.S(Degree of Substitution) etc.

    3. Application difference:

     Sodium CMC is widely used in pharmaceutical, food, cosmetic, paper making, ceramic textile printing industries as thicker, emulsifier. But CMC is mainly used in Oil drilling, Civil engineer and cosmetic industries as blowing agent and dispersing agent.

    Price difference:

     Sodium CMC price is higher compared to CMC, because its production technology is more complex and its cost is also higher. Especially for food grade high viscosity CMC, raw material refine cotton price is much higher.
