Ultra Low Viscosity CMC is a specially engineered grade of Sodium Carboxymethyl Cellulose designed for applications where functional performance is required without significantly increasing system viscosity. It is widely selected by formulators who need dispersion, stabilization, lubrication, or film-forming effects while maintaining excellent fluidity.Hondo Chem ultra low viscosity CMC is a special type of sodium carboxymethyl cellulose (CMC-Na). Its solution viscosity is significantly lower than that of ordinary CMC-Na (usually 1% solution viscosity is less than 50 mPa·s, and the ultra low viscosity CMC produced by our company can be less than 25mpas of 4% aqueous solution viscosity). While maintaining the basic functions of CMC-Na (such as dispersion, stability, and film formation), the ultra low viscosity CMC avoids significant impact on the fluidity of the system and is widely used in papermaking, pharmaceuticals, food, daily chemicals and industrial fields.
Core Application Areas
-
1. Ultra low viscosity CMC in pharmaceutical industry
In oral liquid preparations (such as syrups and suspensions), the ultra-low viscosity carboxymethyl cellulose could combine with water molecules to form an ultra-low viscosity colloidal solution, providing slight thickening, which can improve the suspension of drugs and avoid a sticky taste.
In Eye drops & nasal sprays, the Ultra-low viscosity sodium CMC can be used as a lubricant and stabilizer in eye drops or nasal sprays to prolong the retention time of drugs in the mucosa, prolong the efficacy of drugs, and facilitate the recovery of inflammation.
In the immediate-release tablet coating, the ultra low viscosity carboxymethyl cellulose forms a fast-dissolving film layer when combined with water, which does not affect the disintegration rate of the drug, allowing the drug to slowly release its efficacy and improve the drug's absorption rate.

Functional Properties
High Fluidity
Hondo Chem manufactured ultra low viscosity CMC can form a low viscosity solution even at high concentrations (2%-4%), and has good fluidity under the shear resistance of the aqueous solution, which is suitable for processes that require fast flow (such as injection and spraying).This performance is attributed to controlled polymer chain length and narrow molecular weight distribution, ensuring predictable rheological behavior under shear
Fast Solubility
The ultra low viscosity CMC has a small molecular weight and a moderate degree of substitution (DS). The ultra low viscosity CMC can be quickly dispersed in cold water to avoid agglomeration.Cold-water solubility is achieved through optimized particle size distribution and surface treatment, reducing fish-eye formation during mixing.
Environmental Tolerance
The ultra low viscosity CMC and PAC, due to its unique molecular structure and low molecular weight composition, can maintain stability under high temperature (<80°C) and high salt (such as NaCl concentration ≤15%) conditions, and is suitable for complex industrial environments.Stability tests indicate less than 5% viscosity loss after 24 hours under high salinity and elevated temperature conditions.
Functional Diversity
The ultra low viscosity CMC and PAC have the properties of thickening, suspension, and emulsification, but due to its ultra-low liquid viscosity characteristics, its main goal is to regulate fluidity.This functional balance is achieved through controlled molecular weight and optimized degree of substitution, allowing ultra low viscosity CMC / PAC to form weak hydration and adsorption layers at micro levels.
Application case and Solutions
Pharmaceutical Oral Liquid – Sedimentation Control Without Increasing Viscosity
Conventional CMC grades provided sufficient suspension but significantly increased viscosity, resulting in a sticky taste and reduced patient compliance. Reducing CMC dosage led to fast sedimentation and inconsistent drug distribution.
Solution
Hondo Chem ultra low viscosity pharmaceutical grade CMC was introduced as a suspension stabilizer. Due to its low molecular weight and controlled degree of substitution, the ULV CMC formed a weak hydration layer around drug particles, slowing sedimentation without building a high-viscosity network.
Water-Based Coatings – Pigment Stability With High Spray Fluidity
A water-based coatings manufacturer required a dispersant to prevent pigment sedimentation while maintaining high spray fluidity for automated spraying equipment.
Problem
Traditional thickeners improved pigment suspension but caused excessive viscosity, leading to nozzle blockage, uneven spray patterns, and increased energy consumption during pumping.
Solution
Ultra low viscosity sodium carboxymethyl cellulose was applied as a dispersant and flow regulator. Its molecular structure allowed adsorption onto pigment surfaces, improving dispersion stability without significantly affecting the rheology of the coating system.
Advantages
1. Better fluidity of powders and solutions
Hondo Chem supplied ultra low viscosity CMC do not change to the original viscosity of the system, suitable for precision scenarios requiring low viscosity.Hondo Chem supplied ultra low viscosity CMC is specifically designed to regulate flow behavior without significantly increasing system viscosity. This is achieved by controlling molecular chain length and substitution uniformity, allowing the product to maintain excellent fluidity even at higher solid concentrations. For precision industries such as pharmaceuticals, cosmetics, and coatings, this characteristic ensures accurate dosing, smooth pumping, and consistent spray or injection performance. Compared with conventional CMC grades, ULV CMC minimizes flow resistance, reduces energy consumption during processing, and improves overall production efficiency.
2. Fast dissolution of powders
There is no need for long-term stirring or heating in actual production process, ultra low viscosity CMC could improve production efficiency.Ultra low viscosity CMC demonstrates rapid dispersion and hydration in cold water, eliminating the need for prolonged stirring or heating. This is particularly important for large-scale manufacturing, where time efficiency directly impacts production cost. The fast dissolution behavior results from optimized particle size control and reduced polymer entanglement. In industrial practice, dissolution time can be shortened by 20–35%, enabling faster batch turnover and more stable formulation control.
3. Wide application compatibility
The ultra low viscosity CMC and PAC adapt to pH 4-10, compatible with most anionic / non-ionic ingredients.With a broad pH tolerance range of 4–10 and excellent compatibility with anionic and non-ionic ingredients, ultra low viscosity CMC and PAC can be easily integrated into diverse formulations. This wide compatibility reduces formulation risk and minimizes the need for frequent adjustments when scaling up production. For bulk buyers and formulators, this means higher formulation flexibility, fewer quality issues, and more reliable long-term supply performance.
