In the pharmaceutical sector, CMS serves as a disintegrant in tablets, helping them break down quickly for effective drug release. It is also employed in drug delivery systems due to its biocompatibility and controlled release properties.

In the textile industry, CMS is used as a sizing agent to improve the strength and smoothness of yarns during weaving. It is also utilized in paper manufacturing to increase paper strength and improve surface properties. Additionally, CMS finds applications in water treatment as a flocculant to remove impurities and clarify water. Its versatility and functionality make it a valuable additive across various industries.
