WeKcelo MC -----   Methyl  Cellulose
Each anhydroglucose unit contains three hydroxyl groups, shown in white. By substituting carboxymethyl groups for some of the hydrogens of these
hydroxyls, as shown in Figure 1, sodium carboxymethylcellulose is produced. The average number of hydroxyl groups substituted per anhydroglucose
unit is known as the “degree of substitution,” DS. If all three hydroxyls are replaced, the maximum theoretical DS of 3.0 (impossible in practice) results.
Idealized Unit Structure of CMC, with a DS of 1.0

Optimum water solubility and other desirable physical properties of CMC are obtained at a much lower degree of substitution than 3. The most widely used
types of WekceloCMC have a DS of 0.7 . V
CMC solution characteristics depend on the degree of polymerization (DP) as well as the degree of substitution. Average chain length and degree of substitution
determine molecular weight of the polymer. As molecular weight increases, the viscosity of CMC solutions increases rapidly.
WeKcelo CMC has a minimum purity of 99.5%. it has the following functions and properties:
  • Control Viscosity and rheology
  • Suspending and binding rheology
  • Water retention aid
  • Crystal growth inhibitor
  • Strong ,resistant film former
These properties and functions make it suitable for use in a broad range of applications in the food, pharmaceutical, cosmetic, paper, and other industries.
Various types based on carboxymethyl substitution, viscosity, particle size, and other parameters.


 Major application for WeKcelo CMC:  
Pharmaceutical preparation
Cosmetics and personal care products
Toothpaste
Food : Frozen dairy products ,pet food , bakery products , beverages ,low calorine food , instant products,salad dressings .
Ceramic
Oil field
Construction

Microbiological Information for Use in Foods, Drugs, Cosmetics, and Toiletries
Microbiological Information

WeKceloCMC is routinely sampled and subjected to microbiological testing by an independent laboratory and data are tabulated to provide an ongoing indicator
of control in production. The data generated are not intended to be used to provide product specifications, but typical results using our standard protocol, are shown below.
