Sodium-free Ammonium Carboxymethyl Cellulose
,High Purity Ammonium Carboxymethyl Cellulose
,Easily Dispersible Ammonium Carboxymethyl Cellulose
Ammonium Carboxymethyl Cellulose(CMC-NH4), with CAS No.9086-60-6 andaliases of Amino Cellulose and AmmoniumCMC, is a high-performance cellulose derivative 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.
- Thickening and Thixotropic Performance - Imparts pseudoplasticity:maintains consistency when stationary,and reduces viscosity under shear force(e.g.,troweling,stirring),greatly enhancing.
- Crack Resisitance and Anti-Segregation - The uniform nrtwork structure refines internal pores in mortar,reducing drying shrinkage caused by water migration,thereby lowering the risk of cracking.
- Improved Bonding Strength - The sodium-free formula avoids potential adverse effects of sodium ions on cement hydration,providing better long-tern stability.
Water Solubility and Excellent Formability - As a water-soluble binder,it can be uniformly disoersed in ceramic slurry to form a stable network structure,endowing the green body with good extrusion formability and strength,It is particularly suitable for the extrusion process of complex shapes such as honeycomb ceramics.
- Controlled-release film-forming property - High-viscosity grades (e.g., K100M) canform a uniform and dense film on thesurface of tablets or granules. This film acts as a sustained-release barrier,regulating the dissolution rate of sand achieving the effect of long-term stable release, which is applicable to sustained and controlled-release
preparations. - Stability and formulation compatibility - It has good stability in a certain pH range,is not easy to react with active
pharmaceutical ingredients (APls) orother excipients, and can be compatible with most common pharmaceutical
additives (such as fillers, lubricants),which facilitates the preparation of vari...
- High Purity and Low Impurity Content: The main content (on a dry basis)is generally98.0%. The contents of
impurities such as sodium ions, heavy metals (lead, arsenic, etc.), chlorides and sulfates are strictly controlled. The regquirements for pharmaceutical gradeare particularly stringent, with heavymetal content10ppm, so as to avoidadverse effects on the human body orend products. - Viscosity Stability: The viscosity of different grades (e.g.,K100M, E5, E8) must conform to thenominal range. Under specifiedtemperature and pH conditions, theviscosity change rate after standing for acertain period of time shall be 5%,ensuring stable performance in production and application.
- Degree of Substitution (DS)and Uniformity: The degree of substitution is generallycontrolled between 0.6 and 1.2, withuniform distribution of substituents. Thisdirectly affects its key functions such aswater solubility, water retention and film-forming property, and is a core index fordistinguishing the applicable scenarios ofproducts.
- Physical and Chemical Safety: It has low ignition residue (ash content),with the requirement of s0.5% for pharmaceutical grade and s1.0% for construction and ceramic grades.Meanwhile, it shall be free of peculiarsmell and visible foreign matters to the
naked eye. Pharmaceutical grade products also need to pass microbial limittests, with bacterial count s100cfu/g and mold & yeast count s10cfu/g. - Dispersibility and Solubility: At the specified water temperature (25Ct2C) and stirring speed, it can beuniformly dispersed and dissolved within5-10 minutes without caking, ensuringeasy operation and compatibility in actualproduction.
- Daily Chemical Products Field: As a thickener and stabilizer in shampoosand conditioners, it can increase the
viscosity of the system and improve thesmoothness and film-forming property ofproducts. In toothpaste, it serves as abinder to keep the paste uniform andstable, while also having goodbiocompatibility and causing no irritation
to oral mucosa. - Food Industry Field: Food-grade CMC-NH, can be used as athickener and stabilizer in jams, jellies,dairy products and other products,improving the taste and morphologicalstability of food. With no sodium added,it is suitable for food formulations catering to special dietary needs.
