CMC Powder Solution Viscosity Comparison – 0.25% to 3% @silversonmachines

Uploaded March 2022 | Updated September 2026, 30 minutes ago

See how viscosity and flow change across a range of Carboxymethyl Cellulose (CMC) solution concentrations — from 0.25% up to 3%.

In this video, we demonstrate the hydration and dispersion of CMC using a Silverson High Shear Laboratory Mixer, showcasing the flow characteristics at increasing concentrations.

Please note: Results may vary depending on the type and grade of CMC used. In many cases, even higher concentrations are achievable based on the ingredient's properties.

Silverson offers a full range of mixers capable of handling high-viscosity applications, from lab-scale testing to full-scale production.

$How to Disperse Starch – Mixing Pregelatinized Starches There are many different grades and types of starch. Starch is used as a thickening, stabilizing and binding agent in many food products and other industries such as pharmaceutical tablets and chemicals such as adhesives. Unmodified starches generally don’t increase in viscosity until heated and can be dispersed without difficulty. However, “pregelatinized” starches increase in viscosity as soon as they are added to water. Agglomerates will form making it difficult for conventional agitators to disperse the starch efficiently as they cannot break these down. A high shear mixer can rapidly incorporate pregelatinized starch powder and hydrate it without forming agglomerates, all in a fraction of the time taken by conventional agitators. For small volumes Silverson recommends a high shear Batch mixer for rapid powder incorporating and an agglomerate-free dispersion. For large scale production, the Silverson Flashmix offers a fast, clean and efficient means of dispersing starch.
