Ammonium Carboxymethyl Cellulose(CMC-NH4), with CAS No.9086-60-6 andaliases of Amino Cellulose and AmmoniumCMC, is a high-performance cellulose etherderivative modified by the ammoniation ofcarboxymethyl cellulose, with a molecularformula of CsHisO-N. It appears as white or slightly yellow powder/fibrous particles,serving as a non-toxic, odorless and eco-friendly functional material.
- Tile Adhesives & Putty (Grades: K100M, E15) - High water retention extends open time and enhances workability/bond strength
- Cement Mortars (Grades: E5, E15) - Reduces cracking and improves fluidity/pumpability
- Self-Leveling Compounds (Grade: E5) - Low viscosity ensures superior flow and minimizes segregation
Binder for Honeycomb Ceramic Substrates - Water-soluble support for extrusion; leaves no residue after sintering (decomposes to CO+HO), ideal for automotive exhaust purification carriers.
- Tablet Coating & Sustained-Release Matrices (Grade: K100M) - High-viscosity grade forms controlled-release barriers and modulates drug dissolution
- Ophthalmic Solution Thickener (Grade: E5) - Safe/non-irritating, prolongs ocular residence time
- Appearance: White or off-white powder with no odor or slight odor, free of visible impurities
- Identification: Verified by TLC or UV spectroscopy
- Content Assay: Specific ratio of methyl and hydroxypropyl groups verified by GC or HPLC
- Moisture Content: Below 5% for storage stability
- pH: 6.0-8.0 for solution stability
- Viscosity: Specific range at 2% aqueous solution (25°C)
- Heavy Metal Content: ≤20 ppm (as lead)
- Impurity Testing: Strict controls for non-fibrous impurities and microbial limits
- Solubility: Rapid dissolution in cold water forming clear solution
- Cosmetics & Coatings: Water-based paints (Grade E15) for uniform film formation; shampoo/toothpaste (Grade E5) for suspension enhancement
- Food Industry: Dairy/sauce thickening (Food-Grade HPMC) as gelatin alternative in vegan products
