An important indicator for detecting the quality of sodium carboxymethyl cellulose (CMC): particle size

Particle size, usually referring to the size or diameter of sodium carboxymethyl cellulose（CMC） particles, is one of the important indicators for measuring the quality of CMC, which has a certain impact on the solubility, dispersibility, viscosity, and application effect of CMC.

The influence of particle size on solubility

Finer CMC is more easily dispersed in solvents, thereby accelerating dissolution rate and improving dissolution efficiency. Moreover, CMC with uniform fineness can come into contact with the solvent more fully, reducing agglomeration during the dissolution process and making the dissolution process smoother.

The influence of particle size on viscosity

Generally speaking, CMC with moderate fineness can form a more uniform network structure, thereby endowing the solution with higher viscosity.  However, this does not mean that smaller CMC particles are better.  It is necessary to adjust its fineness appropriately according to the needs of actual application scenarios to achieve optimal viscosity performance.

The influence of particle size on stability

CMC with uniform fineness effectively resists the disturbance caused by gravity and solution flow, thereby maintaining the stability of the solution and preventing delamination or precipitation.

The influence of CMC particle size on application effectiveness

In industries such as food, medicine, and cosmetics, the fineness of CMC directly affects its application effectiveness. For example, in foods such as fruit juice and ice cream, CMC with uniform fineness can be used as a thickener and stabilizer to improve the taste and texture of the food; In the pharmaceutical field, CMC with moderate fineness can be used as a drug excipient to help better disperse and dissolve drugs, and improve their bioavailability.

The particle size of CMC from YuCMC Co., Ltd.

Product particle size:

一、 Conventional particle size: The pass rate of conventional products with 100 mesh is greater than 95%, and can also be adjusted according to customer needs.

二、 Ultra fine particle size:

1.The continuous production line with a 200 mesh pass rate greater than 90% adopts a special process design and is currently the only enterprise with this production line.

2.The product is ultra-fine, has a smooth and silky feel, a shiny white luster, strong fluidity, good dispersibility, and a faster dissolution rate than conventional particle sizes.

3.If dissolved with other components, the dispersion is more uniform, the adhesion is better, and the amount added is smaller.

4.Used in the food industry, it has a smooth and delicate taste; Special particle size products are particularly needed in the field of medical excipients.
