Frequently Asked Questions
Q: What are the primary applications of Sodium Carboxy Methyl Cellulose?
CMC is widely used in construction chemicals, detergents, pharmaceuticals as a medical excipient, and the food industry due to its thickening and stabilizing properties.
Q: How should CMC be stored to maintain its quality?
It should be stored in a cool, dry place away from sunlight and avoid storage under pressure. Unopened packaging can be stored for several years.
Q: Is Sodium Carboxy Methyl Cellulose safe for medical use?
Yes, CMC is a natural polymer derivative that is physiologically harmless, which is why it is frequently used in medical excipient products.
Q: What is the significance of the 'Degree of Substitution' in CMC?
The degree of substitution (typically 0.6-0.9) affects the solubility and viscosity of the product, determining its suitability for specific industrial applications.
Q: How does CMC improve water retention in construction materials?
By forming a stable gel-like structure, CMC prevents the paste from drying too quickly, which reduces shrinkage and prevents cracking after application.
Q: What is the standard packaging for bulk orders?
The product is typically packed in multi-layer paper bags lined with a polyethylene layer, with a standard net weight of 25KG per bag.
